Description
The shaft sleeve is like a strong, protective jacket for that shaft. It is a small, hollow metal cylinder that slides onto the shaft.
The shaft passes through seals and bearings. Over time, these parts can wear a groove into the metal. If the groove wears into the shaft itself, the whole shaft might need to be replaced. That’s a big and expensive job.
But if the groove wears into this replaceable sleeve, you just change the sleeve. It’s a small, affordable part that protects a big, important one.
This is the Busch shaft sleeve, part number 472512673.
The numbers 30x35x20 mm are its exact dimensions. This guarantees it fits your specific pump perfectly. It is designed for Busch R5 RD0300A and RD0360A vacuum pumps.
Replacing a worn shaft sleeve is smart maintenance. It restores a smooth surface for seals to work against. This helps prevent oil leaks and keeps your pump running efficiently.
It’s a simple part that offers big protection for your pump’s core.
