TIMKEN 32930 150x210x38 TS Tapered Roller Bearing

TIMKEN 32930 is a metric single-row TS Tapered Single roller bearing measuring 150x210x38 mm. According to Timken data: d = 150 mm, D = 210 mm, T = 38 mm, B = 38 mm and C = 30 mm. The separable bearing consists of X32930M cone and Y32930M cup. Its tapered roller and raceway geometry accommodates combined radial and axial loads.

TIMKEN 32930 150x210x38 TS Tapered Roller Bearing

TIMKEN 32930 is a metric single-row tapered roller bearing classified by Timken as TS - Tapered Single. Its principal dimensions are 150x210x38 mm, with bore diameter d = 150 mm, outside diameter D = 210 mm and total bearing width T = 38 mm. The bearing has a separable design comprising X32930M cone and Y32930M cup. Timken classifies it in ISO 355 dimensional series 2DC.

TIMKEN 32930 - Characteristics

The 32930 uses tapered rollers operating between tapered inner and outer ring raceways. This geometry enables the bearing to accommodate combined radial and axial loads.

As a single-row tapered roller bearing, it accommodates axial load in one direction. Bearing arrangements requiring axial location in both directions normally use a second bearing arranged according to the requirements of the application.

TIMKEN 32930 Dimensions

Official Timken dimensions for 32930 are:

d - Bore Diameter: 150 mm
D - Outside Diameter: 210 mm
T - Total Bearing Width: 38 mm
B - Cone Width: 38 mm
C - Cup Width: 30 mm
Commercial Dimensions: 150x210x38 mm
ISO 355 Dimensional Series: 2DC

For a tapered roller bearing, the third dimension in 150x210x38 mm must be correctly identified as T, the total bearing width. It should not automatically be described as B.

TS - Tapered Single Construction

Timken classifies 32930 as a TS - Tapered Single bearing. This is the manufacturer's basic single-row tapered roller bearing configuration.

The assembly consists of:

Cone: X32930M
Cup: Y32930M

The cone assembly contains the inner ring, tapered rollers and cage. The cup is the separate outer ring.

This separable construction allows the cone and cup to be mounted independently and is relevant when setting the final bearing arrangement.

Radial and Axial Loads

The tapered geometry generates a contact arrangement capable of supporting radial and axial forces simultaneously. In a single-row configuration, axial load is supported in one direction.

Bearing setting is therefore an important part of the complete installation. Depending on the arrangement, operating clearance or preload must be established correctly to obtain the intended contact conditions.

Timken specifies e = 0.33 and K = 1.78 for this reference.

TIMKEN 32930 Load Ratings

Timken publishes the following values for this exact reference:

Dynamic Radial Rating C1: 324,000 N
Dynamic Radial Rating C90: 84,000 N
e: 0.33
K: 1.78
Y: 1.83

C1 and C90 are Timken catalogue rating parameters. They should be interpreted according to Timken's calculation methodology rather than directly compared with differently defined rating values without checking the applicable calculation standard.

X32930M Cone and Y32930M Cup

The complete TIMKEN 32930 bearing consists of two specifically identified components:

X32930M: cone assembly
Y32930M: outer ring / cup

The cone includes the inner ring, tapered rollers and cage, while Y32930M forms the outer raceway.

This component identification is useful for maintenance and replacement because tapered roller bearing cones and cups can also appear as separately identified catalogue components.

Meaning of 32930

The designation 32930 identifies the metric tapered roller bearing series and size. For the Timken product, the complete technical identification is strengthened by the component references X32930M and Y32930M.

The bearing belongs to the ISO 355 2DC dimensional series according to Timken catalogue data.

Selection and Interchangeability

When selecting an equivalent for TIMKEN 32930, verify:

Bearing Type: Single-row tapered roller bearing
Timken Type: TS - Tapered Single
Bore d: 150 mm
Outside Diameter D: 210 mm
Total Width T: 38 mm
Cone Width B: 38 mm
Cup Width C: 30 mm
ISO 355 Series: 2DC
Load Ratings: Appropriate for the operating conditions
Bearing Setting: Compatible with the bearing arrangement

Identical nominal dimensions alone should not be treated as proof of complete interchangeability. Internal geometry, ratings, tolerances and application requirements must also be considered.

FAQ

What are the dimensions of TIMKEN 32930?

TIMKEN 32930 has a 150 mm bore, 210 mm outside diameter and 38 mm total width, giving commercial dimensions of 150x210x38 mm.

What type of bearing is TIMKEN 32930?

It is a single-row tapered roller bearing, classified by Timken as TS - Tapered Single.

What does 150x210x38 mean?

150 mm is bore diameter d, 210 mm is outside diameter D and 38 mm is total bearing width T.

What are X32930M and Y32930M?

X32930M is the cone assembly and Y32930M is the cup. Together they form the TIMKEN 32930 tapered roller bearing.

Is TIMKEN 32930 a separable bearing?

Yes. The cone assembly and outer ring cup are separable components, which is characteristic of the TS tapered roller bearing design.

What loads can TIMKEN 32930 accommodate?

Its tapered roller geometry allows it to accommodate combined radial and axial loads. As a single-row bearing, axial load is supported in one direction.

Is the 38 mm dimension B or T?

For TIMKEN 32930, the commercial 150x210x38 mm dimension uses T = 38 mm, the total bearing width. Timken also specifies B = 38 mm for the cone width and C = 30 mm for the cup width.

Is a 32930 bearing from another manufacturer automatically interchangeable?

Not solely from the designation or nominal dimensions. Internal geometry, load ratings, tolerances and the requirements of the bearing arrangement should also be verified.
