Sta-Rite C23-58 (2358) Shaft Sleeve — Stainless Steel, 1 in. ID x 1-1/4 in. OD, with O-Ring

The Sta-Rite C23-58 shaft sleeve (2358) is a precision-machined stainless steel slip-fit sleeve for Sta-Rite pumps on the 1-1/4 in. seal, built on 184JM and 215JM motor frames. It slides over the motor shaft so the mechanical seal runs on the sleeve instead of the shaft. A chamfered lead-in makes it easy to start, a keyway in the bore at the other end drives it with the shaft, and the O-ring that seals it to the shaft is included. It measures 1.000 in. ID x 1.250 in. OD x 2.285 in. long. Built to OEM-equivalent standards or higher.

Why replace the sleeve with the seal

The seal runs directly on the sleeve. Once the sleeve is scored or pitted, even a new seal can leak. A fresh C23-58 at every seal change protects the shaft and gives the new seal a true surface to run on.
