Ring Bearing Backup, Kinney, Rotary Piston, Part# 801262 – vacstellar

This ring is a Kinney part. It fits around the bearing and acts as a support, keeping the bearing from moving out of place. Without it, the bearing could shift, causing misalignment, noise, and premature wear. Using a Kinney ring ensures the thickness and dimensions are exactly as specified. A ring that is too thin may not support the bearing properly. One that is too thick could put preload on the bearing. This ring bearing backup is a Kinney replacement part for rotary piston vacuum pumps. It is used to properly position and support bearings inside the pump, ensuring correct alignment and long‑lasting performance. Part number 801262 guarantees a fit during pump rebuild or maintenance.
