About ball thrust bearing

Designed for load that pushes along the shaft, a thrust ball bearing holds a caged ring of balls between two flat washers: a shaft washer and a housing washer. Single-direction types such as the 51100 and 51200 series take thrust one way; double-direction types add a third washer to take it both ways. They suit low to moderate speeds and purely axial duty. Buyers compare bore, outer diameter, height, cage material and washer finish. Common uses include crane hooks, swivels, rotary tables, steering assemblies, vertical pumps, screw jacks and machine tool tailstocks.

Buyer's guide

What to check

  • Bore, outer diameter and height against the number (for example, 51105 = 25 x 42 x 11 mm)
  • Shaft washer and housing washer bores, so each seats on the correct part
  • Cage material (pressed steel, brass or polyamide) and speed rating

What to ask the supplier

  • Ask for axial dynamic and static load ratings
  • Ask about the minimum axial load needed at your running speed
  • Confirm brand, origin and batch marking
