Reliable axial performance by Skf

Practical benefits

High single-direction axial support: You accommodate unidirectional axial forces reliably to maintain stable machine operations under heavy thrust loads.
Simple mounting and maintenance: The separable components allow you to perform quick shaft installations, routine inspections, and servicing with ease.
Durable brass cage design: A robust sheet brass cage guides the rolling balls smoothly, significantly reducing operational friction and wear.

In a nutshell

The right choise for

With the Skf 51103 thrust ball bearing, you reliably accommodate pure single-direction axial loads. This single-direction bearing with a 17 mm bore, 30 mm outside diameter, and 9 mm width prevents the axial displacement of rotating shafts in machinery, machine tool spindles, and rotary tables. The robust sheet brass cage guides the single ball row with high precision, significantly reducing rotational friction and wear. Thanks to its separable design, you can complete shaft mounting, dismounting, and routine maintenance inspections quickly and effortlessly.
