TIMKEN Bearing 21212-B
Category: TIMKEN Bearing > Tapered Roller Bearings > Tapered Roller Bearings - Single Flanged Cups - Imperial
Like the TS bearing design, the TSF design consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft. TSF bearings have flanged cups to facilitate axial location and accurately align seals in through-bored housings.
Material: Bearing steels

Tapered Roller Bearings - Single Flanged Cups - Imperial, TIMKEN Bearing 21212-B, Machined cages for tapered roller bearings are robust in design and are suited for high-speed and high-load applications. Machined cages use alloy steels and are produced through milling and broaching operations. Assembly does not require a close-in operation and rollers can be retained using nibs or staking. Oil holes also can be easily added for extra lubrication for demanding applications. Some designs are silver plated for special applications.
The most common type of cage used for tapered roller bearings is the stamped-steel cage. These cages are mass produced from low-carbon sheet steel using a series of cutting, forming and punching operations. These cages can be used in high temperature and harsh lubricant environments.
Spacer bearing assemblies speed up bearing installation time because there is no need for bearing adjustment. Spacer bearing assemblies are suitable for use with two-row and four-row Timken® tapered roller bearings to preset the bench lateral (bench end play). Most matched bearing assemblies have serial numbers to ensure correct installation sequence. Timken spacer bearings are precisely ground to provide the exact bench lateral required for the particular bearing application. Since each spacer is custom-fitted to a particular set of components, a spacer cannot be used with any other bearing components – even if they carry the same part numbers.
