TIMKEN 32932 160x220x38 Tapered Roller Bearing

TIMKEN 32932 is a single-row tapered roller bearing measuring 160x220x38 mm. The dimensions are d = 160 mm bore diameter, D = 220 mm outside diameter and T = 38 mm total bearing width. The 32932 design uses tapered rollers and separable cone and cup components, allowing combined radial and single-direction axial loads to be accommodated. TIMKEN commercial listings identify this bearing as 32932 / 32932-90KA1.

TIMKEN 32932 160x220x38 Tapered Roller Bearing

TIMKEN 32932 is a single-row tapered roller bearing with principal dimensions of 160x220x38 mm. The 160 mm dimension is the bore diameter d, 220 mm is the outside diameter D and 38 mm is the total bearing width T. Its tapered roller and raceway geometry is designed to accommodate combined radial and axial loading.

TIMKEN 32932 - Characteristics

The 32932 uses a single row of tapered rollers between tapered inner and outer raceways. The geometry allows radial load and axial load to be transmitted simultaneously.

Because this is a single-row tapered roller bearing, axial load is accommodated in one direction. Where axial location is required in both directions, tapered roller bearings are commonly incorporated into an appropriately arranged bearing pair.

TIMKEN 32932 Dimensions

The confirmed boundary dimensions are:

d - Bore Diameter: 160 mm
D - Outside Diameter: 220 mm
T - Total Bearing Width: 38 mm
B - Inner Ring Width: 38 mm
C - Outer Ring Width: 30 mm
Dimensions: 160x220x38 mm

The B = 38 mm and C = 30 mm dimensions are consistent with the standardized 32932 envelope published for this bearing size.

For a tapered roller bearing, the third dimension in 160x220x38 mm should be identified as T = total bearing width, rather than automatically described as B.

Tapered Roller Bearing Construction

The 32932 has the characteristic separable construction of a single-row tapered roller bearing.

The bearing consists of a cone assembly, incorporating the inner ring, tapered rollers and cage, and a separate cup, which forms the outer ring.

This construction allows the cone and cup to be mounted separately. Correct bearing setting after installation is important because the final operating clearance or preload is determined by the complete bearing arrangement.

Radial and Axial Load Capability

The tapered contact geometry enables TIMKEN 32932 to accommodate radial and axial forces simultaneously.

Unlike a conventional deep groove ball bearing, the geometry of a single-row tapered roller bearing creates a defined axial load direction. A second bearing can therefore be used in an opposing arrangement when the shaft must be axially located in both directions.

The actual permissible loads depend on the exact bearing specification, mounting arrangement, lubrication and operating conditions.

32932 and 32932-90KA1

TIMKEN 32932 is also commercially identified as 32932-90KA1. A current product listing identifies 32932-90KA1 as a TIMKEN tapered roller bearing measuring 160x220x38 mm with a listed mass of approximately 4.229 kg.

For product identification and search, retaining both 32932 and 32932-90KA1 on the product page can therefore be useful.

Bearing Setting

A tapered roller bearing should not be selected or installed solely from its boundary dimensions.

The final bearing arrangement must provide the required operating clearance or preload. Incorrect setting can change roller contact conditions, load distribution and operating temperature.

This is particularly important where two single-row tapered roller bearings are mounted in an opposing arrangement.

Selection and Interchangeability

When selecting an equivalent for TIMKEN 32932, verify:

Designation: 32932
Bearing Type: Single-row tapered roller bearing
Bore d: 160 mm
Outside Diameter D: 220 mm
Total Width T: 38 mm
Inner Ring Width B: 38 mm
Outer Ring Width C: 30 mm
Load Capability: appropriate for the application
Bearing Setting: appropriate clearance or preload
Accuracy and Internal Geometry: compatible with the bearing arrangement

The designation and 160x220x38 mm dimensions are important identification parameters, but dimensions alone should not be used as proof of complete interchangeability between manufacturers.
