FAG 23034-E1A-XL-M 170x260x67 mm - Spherical Roller Bearing

Characteristics of FAG 23034-E1A-XL-M

FAG 23034-E1A-XL-M belongs to the 230 dimensional series of double-row spherical roller bearings.

Compared with other spherical roller bearing series having the same bore diameter, the 230 series provides a relatively compact axial cross-section.

The bearing consists of two rows of symmetrical barrel-shaped rollers, an inner ring and an outer ring with a common spherical raceway.

Key construction features:

• Double-row spherical roller bearing.

• Two rows of symmetrical barrel-shaped rollers.

• Self-aligning design with a spherical outer ring raceway.

• Cylindrical bore with a nominal diameter of 170 mm.

• Optimized E1A internal construction.

• Schaeffler X-life performance design.

• Solid brass cage guided by the rolling elements.

• Open bearing construction without integrated seals.

• Lubrication groove and lubrication holes in the outer ring.

The bearing can accommodate substantial radial loads and axial loads acting in both directions.

Its self-aligning construction allows compensation for certain angular deviations between the shaft axis and the housing axis.

Technical Specifications - FAG 23034-E1A-XL-M

The stated load ratings and speed values are catalogue specifications for the designated bearing version and should be checked against the current Schaeffler technical catalogue when finalizing an engineering design.

Reference speed and limiting speed represent different technical parameters. Neither should be interpreted as an unconditional permissible operating speed for every application.

What Does FAG 23034-E1A-XL-M Mean?

23034 - Bearing Series and Size

The designation 23034 identifies a double-row spherical roller bearing belonging to the 230 dimensional series.

Its principal dimensions are:

• d = 170 mm - bore diameter.

• D = 260 mm - outside diameter.

• B = 67 mm - bearing width.

The 230 series is designed to accommodate substantial loads while requiring comparatively limited axial installation space.

E1A - Optimized Internal Design

The suffix E1A identifies a specific FAG spherical roller bearing internal design.

Characteristic features include:

• Two rows of symmetrical barrel-shaped rollers.

• Inner ring construction without a central guiding rib.

• Optimized contact geometry between rollers and raceways.

• Internal arrangement designed to operate with a solid brass cage.

The absence of a central inner ring rib does not mean that the rolling elements are unsupported.

The cage and internal geometry provide the required guidance within the bearing assembly.

XL - Schaeffler X-life Technology

The designation XL identifies the Schaeffler X-life performance design.

X-life bearings incorporate optimized manufacturing and design characteristics intended to improve operating performance.

Depending on the bearing type and application, these improvements may include:

• Increased fatigue life.

• More favourable internal load distribution.

• Reduced frictional losses.

• Improved raceway surface quality.

• Enhanced performance under demanding loads.

However, X-life does not guarantee the same percentage increase in operating life under every set of conditions.

Actual bearing life depends on loading, lubrication, contamination, temperature, mounting accuracy and operating conditions.

M - Solid Brass Cage

The suffix M identifies a solid brass cage in this FAG bearing design.

The cage maintains the correct spacing of the barrel-shaped rollers and helps guide their movement during operation.

In FAG 23034-E1A-XL-M, the brass cage is guided by the rolling elements.

The M designation should not be confused with steel or polyamide cage constructions.

Double-Row Spherical Roller Bearing Construction

Two Rows of Symmetrical Barrel Rollers

FAG 23034-E1A-XL-M contains two rows of barrel-shaped rolling elements.

The rollers operate between the inner ring raceways and the common spherical raceway of the outer ring.

This arrangement allows the bearing to support high radial loads together with axial loads in both directions.

The design is particularly relevant where heavy loading and angular misalignment may occur simultaneously.

Self-Aligning Capability

The spherical outer ring raceway allows the inner bearing assembly to adjust its angular position relative to the outer ring.

This self-aligning capability helps accommodate:

• Shaft-to-housing misalignment.

• Certain shaft deflections.

• Angular deviations occurring during operation.

The permissible misalignment angle depends on the operating load, bearing arrangement and surrounding components.

A single universal misalignment value should not be assumed for all operating conditions.

Cylindrical Bore

FAG 23034-E1A-XL-M has a cylindrical bore with a nominal diameter of 170 mm.

This is an important distinction from tapered-bore versions identified by the additional suffix K.

Cylindrical and tapered bore bearings require different mounting arrangements and shaft seat designs.

Lubrication Arrangement

The bearing incorporates a lubrication groove and lubrication holes in the outer ring.

These features allow lubricant to be supplied to the internal rolling contact areas.

Because FAG 23034-E1A-XL-M is an open bearing, it does not include integrated seals to protect against external contaminants.

Suitable sealing arrangements must therefore be provided by the bearing housing or surrounding machinery.

Load Ratings of FAG 23034-E1A-XL-M

The catalogue load ratings for this bearing version are:

Basic Dynamic Load Rating Cr

The basic dynamic radial load rating is used in bearing fatigue life calculations according to the relevant standardized calculation method.

It does not represent the maximum permissible operating load under all conditions.

The actual bearing life depends on the equivalent dynamic load, rotational speed, lubrication conditions, contamination and other application factors.

Basic Static Load Rating C0r

The basic static radial load rating relates to a defined criterion for permanent deformation at the rolling element and raceway contact areas.

When selecting the bearing, engineers must consider the required static safety factor, loading conditions and application requirements.

Operating Speeds

The catalogue speed values are:

Limiting Speed

The limiting speed is a catalogue parameter associated with the bearing's mechanical operating limitations.

It must not be treated as an unconditional maximum operating speed independent of lubrication, temperature, load and installation conditions.

Reference Speed

The reference speed is a standardized thermal reference parameter used in bearing selection and operating temperature assessment.

It is not the same as the limiting speed.

The permissible operating speed must be determined by considering the complete bearing arrangement and actual service conditions.

FAG 23034-E1A-XL-M vs Other Versions

Bearings with the same basic designation may differ in internal clearance, bore configuration and other characteristics.

These designations illustrate construction and clearance differences. Availability of individual versions should be verified against the manufacturer's catalogue.

These bearing versions are not automatically interchangeable.

Bore configuration and radial internal clearance are particularly important because they affect mounting methods, shaft fits and operating conditions.

Normal Clearance vs C3 and C4

The standard FAG 23034-E1A-XL-M designation does not include an additional C3 or C4 clearance suffix.

It therefore identifies the normal radial internal clearance version.

C3 and C4 designate progressively larger clearance groups.

The correct clearance class must be selected according to:

• Shaft and housing fits.

• Temperature differences between bearing rings.

• Operating loads.

• Rotational speed.

• Required operating clearance.

A larger clearance class does not automatically improve bearing performance.

Applications of FAG 23034-E1A-XL-M

Spherical roller bearings of this construction are used in industrial machinery where substantial radial loads, variable loading or shaft misalignment may occur.

Typical application categories include:

• Industrial gearboxes.

• Paper manufacturing machinery.

• Conveyor systems and bulk material handling equipment.

• Industrial fans.

• Mining machinery.

• Metallurgical equipment.

• Raw material processing machinery.

• Large industrial shaft assemblies.

These are general application examples for spherical roller bearings, not a verified list of specific machines fitted with FAG 23034-E1A-XL-M.

When Is This Bearing Design Appropriate?

A spherical roller bearing may be an appropriate choice when a machine requires both high radial load capacity and the ability to compensate for angular misalignment.

Final selection must account for:

• Radial and axial loading.

• Operating speed.

• Operating temperature.

• Shaft and housing fits.

• Lubrication conditions.

• Required bearing life.

• Contamination protection.

• Mounting and maintenance requirements.

Bearing Selection and Interchangeability

Before purchasing FAG 23034-E1A-XL-M, verify:

1. Complete manufacturer designation: 23034-E1A-XL-M.

2. Dimensions: 170x260x67 mm.

3. Bore configuration: cylindrical.

4. Internal design: E1A.

5. X-life performance designation: XL.

6. Cage: solid brass.

7. Required radial internal clearance.

8. Radial and axial operating loads.

9. Lubrication and contamination protection.

10. Shaft and housing fits and required bearing life.

A bearing from another manufacturer with identical dimensions may be considered as an alternative only after comparing its construction, load ratings, internal clearance, cage design and other relevant specifications.

Identical dimensions alone do not establish complete technical interchangeability.

Installation and Operating Recommendations

Before installation, inspect the shaft, housing and locating components.

Particular attention should be given to:

• Correct shaft and housing tolerances.

• Appropriate interference or clearance fits.

• Clean mounting surfaces.

• Alignment of the bearing arrangement.

• Suitable mounting tools and procedures.

• Avoiding transmission of mounting forces through the rolling elements.

• Correct lubricant selection.

• Adequate lubrication supply.

• Effective protection against contamination.

• Verification of operating clearance after mounting.

For large spherical roller bearings, correct ring seating and fit selection are especially important.

Improper mounting may alter the internal operating clearance and lead to excessive temperature, vibration or premature bearing damage.

Lubrication

FAG 23034-E1A-XL-M is an open bearing requiring an appropriate lubrication system.

The lubricant and lubrication method must be selected according to operating speed, load, temperature and environmental conditions.

The lubrication groove and holes in the outer ring support lubricant distribution within the bearing assembly.

Storage

Store the bearing in its protective packaging in a clean, dry environment.

Protect it from moisture, dust, corrosive substances and mechanical impact.

The bearing should be unpacked only when required for inspection or installation.
