CRBC20025 Thrust Roller Bearing
Selection Guide
Thrust bearings carry axial load only and cannot carry radial load, so they must be combined with a radial bearing that provides radial location. Key selection points: thrust ball (point contact, suited to moderate speed and light-to-moderate pure axial load) versus thrust roller (line contact, much higher axial capacity and shock resistance); single versus double direction; and types with a sphered seating ring that compensate misalignment. At high speed, the limiting speed of thrust ball bearings drops markedly due to rolling element centrifugal effects.

Can you provide engineering drawings and material certificates for CRBC20025?
Yes—CAD/DXF/PDF high-precision drawings and 3.1 material certificates (GCr15 bearing steel) for CRBC20025 are available on request from RAYSDE.
CRBC20025 What is the difference between a thrust ball bearing and a thrust roller bearing?
Thrust ball bearings use point contact: low friction and a relatively high limiting speed, but limited axial capacity, suiting moderate speed and light-to-moderate pure axial load. Thrust roller bearings (cylindrical, tapered or spherical roller types) use line contact with far higher axial capacity and shock resistance, suiting heavy thrust duties such as mill screw-downs and marine propulsion. If your axial load is heavy or subject to shock, choose a thrust roller type.
CRBC20025 Why must a thrust bearing always be paired with a radial bearing?
By design a thrust bearing carries axial load only — it cannot carry radial load at all and cannot locate the shaft radially. A radial bearing such as a deep groove ball or cylindrical roller bearing must therefore carry the radial load and maintain concentric location, while the thrust bearing handles axial load alone. Also ensure shaft shoulder and housing faces are square; otherwise load becomes eccentric, stress concentrates locally and life drops sharply.
