This WHEELER-REX 275828 thrust race is a hardened bearing race used in the thrust bearing stack of Wheeler-Rex shut-off tools. It provides a smooth, wear-resistant surface for the mating thrust bearing to ride against, helping the tool operate smoothly under load and reducing metal-to-metal wear.
Common Applications
- Used in Wheeler-Rex Model 75 and Model 77 shut-off tools
- Installed as part of the thrust bearing assembly (works with the matching thrust bearing)
Notes for Service & Replacement
- Often shown as (2) thrust races used per tool in the Model 75/77 parts diagrams
