Roller Thrust Bearing

Roller thrust bearings are designed to carry very high axial (thrust) loads with excellent rigidity, making them ideal for heavy-duty applications where loads push along the shaft direction. Using rollers instead of balls increases contact area, improving load capacity and reducing deformation under load—especially in slow-to-moderate speed systems.

Key Features

• Very high axial load capacity (roller contact)

• High stiffness for stable axial positioning

• Better suited for heavy loads than thrust ball bearings

• Available as cylindrical roller thrust or tapered roller thrust designs

• Typically separable for easier installation and maintenance

Common Applications

Screw jacks, presses, extruders, cranes/hoists, rotary tables, heavy gearboxes, vertical shafts, and industrial turntables.

Selection Notes

Roller thrust bearings are primarily for axial loads and have limited radial load capacity (unless using specific combined-load designs). Match bore/OD/height, confirm required axial load direction, and choose cage/material and lubrication based on speed and operating temperature. Ensure mounting faces are flat and rigid to prevent uneven loading.
