H913849 / H913810 TIMKEN 69.850x146.050x41.275 mm Tapered Roller Bearing

H913849 / H913810 TIMKEN 69.850x146.050x41.275 mm Tapered Roller Bearing

H913849 / H913810 TIMKEN is a complete single-row tapered roller bearing set of the TS (Tapered Single) type, consisting of the H913849 cone assembly and H913810 cup. The complete bearing has a 69.850 mm bore diameter, 146.050 mm outside diameter and 41.275 mm overall width. Its tapered roller construction is designed to accommodate combined radial and axial loads.

Technical data - TIMKEN H913849 / H913810

Is H913849 / H913810 TIMKEN a complete bearing?

Yes.

The designation:

H913849 / H913810

identifies the complete TIMKEN single-row tapered roller bearing set.

The set consists of:

H913849 - cone assembly

and

H913810 - cup

Together, these components form the complete H913849 / H913810 tapered roller bearing.

This distinction is important when ordering because H913849 alone does not represent the complete bearing set.

What is H913849?

H913849 is the TIMKEN designation for the cone assembly.

The cone assembly consists of:

• inner ring
• tapered rollers
• cage

H913849 is therefore not simply an inner ring. It is the complete inner bearing assembly.

However, it still requires the corresponding outer ring to form the complete tapered roller bearing.

For this bearing, the corresponding cup is:

H913810

What is H913810?

H913810 is the cup, or outer ring, of the tapered roller bearing.

The inner surface of the cup forms the outer raceway on which the tapered rollers of the H913849 cone assembly operate.

Therefore:

H913849 = cone assembly

H913810 = cup

H913849 / H913810 = complete tapered roller bearing set

Dimensions of H913849 / H913810

TIMKEN specifies the principal dimensions of the complete bearing as:

69.850x146.050x41.275 mm

where:

• d = 69.850 mm - bore diameter
• D = 146.050 mm - outside diameter
• T = 41.275 mm - overall bearing width

The corresponding imperial dimensions are:

• d = 2.7500 in
• D = 5.7500 in
• T = 1.6250 in

The imperial values explain the characteristic metric dimensions of this bearing series.

Important: T, B and C are different dimensions

For tapered roller bearings, the overall bearing width must not be confused with the widths of the individual cone and cup components.

TIMKEN specifies:

T = 41.275 mm

Overall width of the complete bearing.

B = 39.688 mm

Cone width.

C = 25.400 mm

Cup width.

The correct principal dimensions of the complete bearing are therefore:

69.850x146.050x41.275 mm

and not 69.850x146.050x39.688 mm.

TS - Tapered Single construction

TIMKEN classifies H913849 / H913810 as:

TS - Tapered Single

This is a single-row tapered roller bearing design consisting of two main separable components:

• cone assembly
• cup

The separable construction allows the cone and cup to be mounted separately and the bearing arrangement to be adjusted according to the requirements of the machine.

How does H913849 / H913810 work?

The rollers and raceways have tapered geometry.

This enables the bearing to accommodate:

• radial loads
• axial loads
• combined radial and axial loads

In a single-row tapered roller bearing, axial load capacity acts primarily in one direction.

For this reason, tapered roller bearings are frequently installed in appropriately arranged pairs when axial load support in both directions is required.

The correct arrangement depends on the machine design and operating conditions.

Load ratings of TIMKEN H913849 / H913810

TIMKEN specifies:

Dynamic radial load rating C1: 273 kN

Static radial load rating C0: 256 kN

TIMKEN also specifies:

Dynamic axial rating Ca90: 94.7 kN

and:

C90: 70.7 kN

These are catalogue engineering ratings used in bearing calculations.

They should not be interpreted as universal maximum permissible operating loads for every machine.

Correct bearing selection requires consideration of the complete operating conditions.

Calculation factors

TIMKEN specifies the following calculation factors:

• e = 0.78
• K = 0.75
• Y = 0.77

These parameters are used in bearing load calculations according to the manufacturer's engineering methodology.

Bearing life and application calculations should be based on current TIMKEN engineering data and the actual operating conditions of the bearing arrangement.

Separable cone and cup design

H913849 / H913810 has a separable tapered roller bearing construction.

The H913849 cone assembly and H913810 cup can be separated.

This can facilitate:

• installation
• removal
• component inspection
• bearing adjustment
• setting of axial clearance
• setting of preload in appropriately designed arrangements

Separable construction does not mean that arbitrary cones and cups with similar dimensions can be combined.

The internal geometry of the cone and cup must be compatible.

For this product, the specified combination is:

H913849 + H913810

H913849 vs H913810

H913849

is the cone assembly containing the inner ring, tapered rollers and cage.

H913810

is the cup, or outer ring.

When a complete bearing is required, the correct complete product designation is:

H913849 / H913810 TIMKEN

Is H913849 alone a complete bearing?

No.

H913849 is a cone assembly consisting of the inner ring, tapered rollers and cage.

The corresponding H913810 cup is required to form the complete H913849 / H913810 bearing.

This distinction is important when purchasing individual tapered roller bearing components.

Is H913810 a complete bearing?

No.

H913810 is the cup, which is the outer ring of the tapered roller bearing.

The complete bearing set requires:

H913849 + H913810

H913849/810 - abbreviated designation

The shortened notation:

H913849/810

is commonly used as a compact reference to the complete pair:

H913849 / H913810

The designation may therefore also be encountered as:

H 913849/810

For precise technical identification, B2B procurement and product documentation, displaying both full component numbers is preferable:

H913849 / H913810 TIMKEN

Radial and axial loads

Tapered roller bearings are designed specifically for combined loading conditions.

Their geometry enables forces to be transmitted through the tapered rollers and raceways in both radial and axial components.

Actual bearing performance depends on factors including:

• radial load
• axial load
• load direction
• rotational speed
• bearing setting
• lubrication
• shaft and housing fits
• operating temperature
• contamination
• required service life

Engineering calculations should be based on verified data for the exact bearing.

Bearing clearance and preload

Correct bearing setting is particularly important with tapered roller bearings.

Depending on the application, the bearing arrangement may require a specified:

• axial clearance
• operating clearance
• preload

Incorrect adjustment can result in:

• excessive friction
• increased operating temperature
• excessive bearing clearance
• inaccurate shaft guidance
• premature roller or raceway damage
• reduced bearing life

The required setting should be determined according to the machine manufacturer's specifications and appropriate TIMKEN engineering recommendations.

How to select a replacement for H913849 / H913810

Before selecting an equivalent bearing, verify:

• 69.850 mm bore diameter

Identical principal dimensions alone do not guarantee complete interchangeability.

Typical applications of tapered roller bearings

Single-row TS tapered roller bearings are widely used in bearing arrangements exposed to combined radial and axial loads.

Typical application areas for this bearing category include:

• industrial gearboxes
• reduction gear units
• drive shafts
• transmission assemblies
• heavy industrial machinery
• agricultural machinery
• construction machinery
• material handling equipment
• conveyor systems
• production machinery
• maintenance operations
• industrial service

These are typical applications of tapered roller bearings as a product category. They do not confirm that H913849 / H913810 is specified for a particular machine, vehicle or OEM application.

Installation of H913849 / H913810

Before installation, inspect the shaft, housing and all mating surfaces and maintain a high level of cleanliness.

Good installation practice includes:

• keeping rollers and raceways clean
• using appropriate mounting tools
• correctly installing the cone
• correctly installing the cup
• checking shaft and housing fits
• applying the appropriate lubricant
• setting the required axial clearance
• setting the required preload where specified

Tapered roller bearing adjustment must correspond to the requirements of the specific bearing arrangement.

Incorrect clearance or excessive preload can increase friction and operating temperature and may reduce bearing service life.
