INA GYE35-KRR-B 35x72x42.9 Radial Insert Ball Bearing

INA GYE35-KRR-B 35x72x42.9 Radial Insert Ball Bearing

INA GYE35-KRR-B, currently designated GYE35-XL-KRR-B by Schaeffler, is a radial insert ball bearing with dimensions 35x72x42.9 mm. It has a 35 mm bore, 72 mm spherical outside diameter and width B = 42.9 mm. Its construction combines a spherical outer ring surface, R seals on both sides and grub screws for locating the inner ring on the shaft.

Exact product identification:

INA + GYE35-KRR-B + GYE35-XL-KRR-B + 35x72x42.9 mm + radial insert ball bearing + KRR + grub-screw locking

INA GYE35-KRR-B – Technical Characteristics

INA GYE35-KRR-B Dimensions – 35x72x42.9 mm

The principal dimensions are:

d = 35 mm – bore diameter

Dsp = 72 mm – spherical outside diameter

B = 42.9 mm – width

Additional catalogue dimensions include:

C = 19 mm – outer ring width

C2 = 22.5 mm

S = 17.5 mm

d1 = 46.8 mm

The commonly used dimensional search format is:

35x72x42.9 mm

However, dimensions alone are not sufficient to confirm interchangeability. Outer-ring geometry, shaft-locking method, sealing arrangement and housing compatibility must also be checked.

What Is INA GYE35-KRR-B?

INA GYE35-KRR-B belongs to the radial insert ball bearing family and is designed for installation in compatible bearing housings.

Unlike a conventional deep groove ball bearing, the GYE35 design incorporates several features specifically intended for housed-bearing arrangements:

extended inner ring

spherical outer ring surface

integrated shaft locking by grub screws

and:

sealing on both sides.

The product should therefore be identified by its complete design rather than simply as a bearing with a 35 mm bore.

Spherical Outer Ring Surface

The outer ring of GYE35-KRR-B has a spherical outside surface.

When installed in a compatible housing with a corresponding spherical seat, this geometry allows the bearing unit to compensate for limited static misalignment resulting from mounting.

This should not be confused with the internal self-aligning mechanism of a conventional double row self-aligning ball bearing.

In the GYE35 design, alignment capability is provided by the interface between the:

spherical bearing outer surface

and:

matching housing seat.

Shaft Location by Grub Screws

One of the most important features of INA GYE35-KRR-B is its shaft-locking system.

The bearing is located on the shaft using grub screws in the extended inner ring.

This locking method distinguishes the GYE series from other radial insert bearing designs that may use:

an eccentric locking collar

or:

an adapter sleeve.

The locking method must therefore be checked when selecting a replacement insert bearing.

What Does KRR Mean?

For this INA bearing series, KRR identifies a design with R-type seals on both sides.

The sealing arrangement helps limit contamination entering the bearing while retaining lubricant around the rolling elements and raceways.

KRR is therefore an important part of the exact product identification and should not be omitted when checking a replacement.

What Does B Mean?

The B suffix forms part of INA/Schaeffler's design designation for this radial insert bearing configuration.

Bearing suffixes are manufacturer-specific.

The INA suffix B should therefore not be interpreted according to SKF, NSK, NTN, KOYO, TIMKEN or another manufacturer's designation system.

GYE35-KRR-B vs GYE35-XL-KRR-B

The bearing is widely encountered under the designation:

GYE35-KRR-B.

Current Schaeffler documentation identifies the current version as:

GYE35-XL-KRR-B.

The XL designation identifies the current X-life version.

Both references are important for spare-parts identification because maintenance engineers and purchasing departments may search using a reference taken from:

an older installed bearing

a machine manual

historical technical documentation

ERP purchasing records

or:

current Schaeffler documentation.

For this reason, both GYE35-KRR-B and GYE35-XL-KRR-B should be indexed on the product page.

Basic Dynamic Load Rating Cr

For the current:

GYE35-XL-KRR-B

version, the basic dynamic radial load rating is:

Cr = 27,500 N = 27.5 kN.

Cr is a standardized parameter used in bearing rating-life calculations under dynamic loading.

It should not be interpreted simply as the maximum permissible operating load under all conditions.

Basic Static Load Rating C0r

The basic static radial load rating is:

C0r = 15,300 N = 15.3 kN.

C0r is used when evaluating the bearing under static loading and specified very-low-speed operating conditions.

GYE35-KRR-B vs GRAE35-NPP-B

GYE35 and GRAE35 belong to the radial insert bearing family but use different shaft-locking arrangements.

A key difference is:

GYE35-KRR-B – shaft location by grub screws

GRAE35-NPP-B – shaft location by eccentric locking collar.

Consequently, bearings should not be considered interchangeable merely because their bore and outside diameter are similar.

Selection and Interchangeability

When selecting a replacement for INA GYE35-KRR-B, verify:

bearing type – radial insert ball bearing

d = 35 mm

Dsp = 72 mm

B = 42.9 mm

C = 19 mm

spherical outer ring surface

shaft location by grub screws

R seals on both sides

housing compatibility

required load ratings

and:

mounting and operating conditions.

Matching the nominal 35x72x42.9 mm dimensions alone does not confirm full interchangeability.

INA GYE 35 KRRB – Is This the Same Bearing?

Yes. The search phrase:

INA GYE 35 KRRB

is a common way of entering the designation:

INA GYE35-KRR-B.

The same bearing reference may be searched as:

GYE35KRRB

GYE35 KRRB

GYE 35 KRRB

GYE35 KRR B

or:

GYE35-KRR-B.

For technical identification, use the manufacturer's complete designation:

GYE35-KRR-B

or the current:

GYE35-XL-KRR-B.

35x72x42.9 Bearing – How to Identify the Correct Product

If the designation on an installed bearing is damaged or unreadable, a buyer may search by dimensions:

35x72x42.9 bearing

35x72x42.9 insert bearing

INA 35x72x42.9 bearing

35mm bore insert bearing

or:

72mm OD insert bearing.

Dimensions are useful for narrowing the search, but they do not identify the complete construction.

For this product, the full identification is:

INA + GYE35-KRR-B + 35x72x42.9 mm + spherical outer ring + KRR + grub-screw locking.

GYE35 Bearing – Is the Base Designation Enough?

A search for:

GYE35 bearing

identifies the bearing family, but the complete suffix must be checked before ordering.

For this product, the complete reference is:

INA GYE35-KRR-B.

The KRR sealing configuration and grub-screw shaft locking are important construction features and should be confirmed when comparing alternatives.

GYE35-KRR-B vs Standard 6207 Bearing

Both bearing families use a nominal:

35 mm bore.

However, they are fundamentally different bearing designs.

GYE35-KRR-B is a radial insert ball bearing with:

spherical outer ring surface

extended inner ring

grub-screw shaft locking

and:

integrated sealing.

A conventional 6207 deep groove ball bearing should therefore not be considered a replacement merely because it also has a 35 mm bore.
