Frequently asked questions about 51100
What does the open design mean on a 51100 bearing?
The 51100 (10mm x 24mm x 9mm) is supplied open — without seals or shields — so lubrication and relubrication come from the surrounding housing or an external system. Compare seal types before deciding on the replacement.
Does the 51100 come with C3 clearance?
This directory lists the 51100 with CN (Standard). C3 (increased internal clearance) versions are common for higher operating temperatures, higher speeds, or press-fit arrangements — specify the required clearance on your RFQ so the quotation matches the application. Read the clearance guide.
The 51100 is listed as a 10×24×9mm thrust ball bearing in open configuration. Part of the 51100 series, the directory records chrome steel gcr15 and P0 (ABEC-1) precision grade for RFQ verification.
The 51100 uses the same part number designation across SKF, FAG, NSK, NTN, and Timken catalogs. This is a standardized thrust ball bearing with industry-standard boundary dimensions. Confirm the housing style, shaft diameter, and seal type before ordering a replacement.
About the 51100 Series
The 51100 series is a single direction thrust ball bearing designed for pure axial loads. The separable design (shaft washer, housing washer, ball/cage assembly) handles axial forces in one direction only. Used in automotive transmissions, machine tool spindles, and vertical pump shafts.
Common Applications
- Vertical Shafts
- Hook Cranes
- Centrifugal Pumps
