Thrust Ball Bearing

Thrust ball bearings are divided into single and double direction types.

Thrust ball bearings are divided into single and double direction types.

The former is able to accommodate axial load in one direction, while the latter is able to accommodate it in both directions. Neither is suitable for applications that involve radial load or high-speed rotation.

Bearings whose housing washer back face is spherical (with a spherical back face or an aligning seat washer) are designed with a self-aligning capability and can accommodate the effects of inaccurate mounting.

Spherical Thrust Roller Bearings

Spherical thrust roller bearings are designed to carry high axial loads. They can also support radial load if magnitude is no more than 55% of the axial load being carried. These bearings are not suitable for high-speed rotation. Having a spherical housing washer raceway surface, these bearings are self-aligning and capable of adjusting to axial inclination. They are usually used with oil lubrication

FAQ

What is a tapered roller bearing?

A tapered roller bearing is a bearing in which tapered rollers (truncated conical rollers) are inserted between the cup (outer ring) and cone (inner ring). The rollers are guided by the cone back face rib.

They have high radial and axial (thrust) load capacities at low to intermediate speeds. Taper roller bearings are available in single-row, two-row and four-row designs. With single-row bearings, the thrust load capacity is about 60% of the radial capacity. Double-row bearings have a greater radial load capacity and can handle thrust loads from both directions. The rollers can be configured so that the contact lines to the races converge or diverge towards the axis of rotation. Diverging double-row bearings increase the rigidity of the shaft mounting, but converging bearings do not. Other configurations for double-row bearings feature a single outer ring and two inner rings, or two outer rings and a single inner ring. Four-row tapered roller bearings consist of four rows of alternating converging and diverging rollers.
