What is the difference between single-direction and double-direction thrust bearings?

Single-direction thrust ball bearings (511xx/512xx/513xx) have one shaft washer, one housing washer, and one ball-cage assembly — they handle axial load in one direction only. Double-direction types (522xx/523xx) have one shaft washer, two housing washers, and two ball-cage assemblies, handling axial load in both directions. Choose double-direction when axial forces alternate, such as in vertical shafts with reversing loads.

Thrust Ball Bearings: SKF 51100/51200/51300 Series

Name: Thrust Ball Bearings: SKF 51100/51200/51300 Series
Brand: SKF

Pure axial load, one simple answer: SKF thrust ball bearings sandwich a ball complement between a shaft washer and a housing washer, supporting vertical shafts, crane hooks, and screw jacks with free rotation. Single-direction 51100, 51200, and 51300 series cover 10mm to 150mm bores; double-direction 52200 and 52300 types handle reversing thrust. The 51300 series takes static loads to 500 kN for heavy platens and indexing tables, while small 51100 bores spin to 6,000 RPM. One rule: they take no radial load, so pair them with a radial bearing. Crane operators, machine shops, and vertical pump maintenance teams across Noida-NCR pick up 51106 through 52210 from our counter. Stocked at Sector 9, Noida; WhatsApp for price.

Frequently Asked Questions: Thrust Ball Bearings

No. Thrust ball bearings are built exclusively for axial (thrust) loads. They cannot handle any radial load. In most applications, a thrust ball bearing pairs with a radial bearing (such as a deep groove ball bearing) that supports the radial forces. Applying radial load to a thrust bearing causes rapid failure.
