Thrust Ball Bearings — SKF 51100/51200/51300 Series

SKF Thrust Ball Bearings in the 51100, 51200, and 51300 series are purpose-built to carry pure axial loads in one direction at moderate speeds. Their flat washer-like profile with a ball complement sandwiched between a shaft washer and a housing washer makes them the simplest and most cost-effective solution for axial load support. Available in single-direction (511) and double-direction (522/523) configurations, these bearings are widely used in crane hooks, screw jacks, turntables, indexing tables, and vertical shaft arrangements. SKF's precision-ground raceways ensure smooth rotation even under heavy thrust, while the pressed steel cage maintains uniform ball spacing for quiet, vibration-free operation. The 51300 series offers higher load ratings than the 51100 and 51200 for demanding applications. Shri Narayan Machinery LLP in Noida stocks SKF thrust ball bearings for immediate delivery to industries across Delhi NCR, Greater Noida, and Ghaziabad.

Applications

The Thrust Ball Bearings is used across a wide range of industrial applications:

  • Crane hooks and swivels — supporting vertical loads with free rotation
  • Screw jacks and lifting devices — thrust loads from lead screw mechanisms
  • Turntables and indexing tables — smooth axial rotation under heavy platens
  • Vertical pump shafts — supporting rotor weight in vertical motor-pump sets
  • Machine tool tailstocks — axial load from live center pressure
  • Automotive clutch release bearings — thrust during engagement/disengagement

Frequently Asked Questions — Thrust Ball Bearings

No. Thrust ball bearings are designed exclusively for axial (thrust) loads. They cannot handle any radial load. In most applications, a thrust ball bearing is used alongside a radial bearing (such as a deep groove ball bearing) that supports the radial forces. Applying radial load to a thrust bearing will cause rapid failure.
