Bearing, Set of 6, Leybold, Ruvac, Part# RA9001B

This is a complete set of six bearings for large Leybold Ruvac vacuum pumps. It fits models RA9001, RA5001, and RA7001S . The set includes five radial ball bearings (Part #330026) and one radial ball bearing (Part #330027) . These bearings support the rotating parts inside your pump. They reduce friction and wear. A direct replacement set that keeps your pump running smoothly.

Big pumps like the RA9001, RA5001, and RA7001S work hard every day . They have two impellers that spin in opposite directions very close to each other . The bearings inside take a lot of stress.

Over time, these bearings wear down. You might notice strange noises. The pump might feel hot. Or you might see metal flakes in the oil.

When you do a full pump rebuild, you need to replace all the bearings. That is exactly what this set is for.
