Product description of TIMKEN Bearing 32021X

TIMKEN Bearing 32021X,Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. Timken® tapered roller bearing assemblies are precisely designed to manage both radial and axial loads, even in the most unforgiving conditions.Double- or two-row Timken® tapered roller bearings feature double cups and two single cones. They are available in a variety of configurations for general industrial and automotive applications. And related type you may also like TIMKEN Bearing 32024X. This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the inner race assembly and the outer race. It is typically mounted in opposing pairs on a shaft. Size Range ID 7.937 to 1562.100 mm (0.31225 to 61.5000 in.) OD 31.991 to 1806.575 mm (1.2595 to 71.1250 in.) Design Attributes Single cone and cup One-piece pressed steel cage retains rollers on the cone and spaces them evenly Pin type cages also available Applications Vehicle front wheels Differential and pinion configurations Conveyor rolls Machine tool spindles Trailer wheels TIMKEN Bearing 32021X,Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. An assembly of a pair of roller bearings in which the inner bearing rings are axially spaced apart by a first member and the outer bearing rings are spaced apart by a second member with one of the inner or outer ring of each bearing being an axially outer bearing ring spaced axially further from the outer bearing than the other ring of that bearing. The method comprises forming an assembly of the two members and bearings in which one of the axially outer bearing ring is a loose fit on one of the first and second members, and then axially moving the axially outer bearing ring of the one bearing which is loose fit in a direction towards the other bearing to create a pre-load, and then increasing the degree of pre-load to effect elastic deformation of that ring and thereby create a shrink fit type interface load. TIMKEN Bearing 32021X,Tapered Roller Bearings TDI (Tapered Double Inner) Imperial. A method of setting the clearance of a tapered roller bearing assembly of the type having a housing with an access opening, and in which housing is positioned an input shaft engaging a worm or gears for driving an output gear engaging an output shaft mounted on a bearing assembly for transmitting power. The method includes the steps of first tightening a removable cover in the housing to a point in contact with the bearing assembly and having a predetermined torque value, and thereafter backing the cover away from the bearing assembly by a distance calculated by the following formula: End play setting angle in degrees=(360 degrees)×(Clearance constant)×(Desired bearing clearance in inches)/(Thread pitch in inches). This method achieves a correct clearance setting defined by the end play setting angle in degrees where the cover is rotated by the number of degrees in the end play setting angle to reduce the predetermined torque value. The last step is to lock the cover in a position that defines the correct.
