Rexnord 40BSK22KL Sprocket

Rexnord 40BSK22KL Sprocket is a Rexnord-brand drive sprocket identified by the model number 40BSK22KL. It features a keyed bore with a 1-3/16 inch shaft diameter, designed to accept a matching shaft key and deliver positive torque transmission without slip. The listing specifies a keyed bore, reinforcing that a key and slot are used to lock the sprocket to the shaft. The 40BSK22KL designation distinguishes this particular sprocket within Rexnord's catalog from other bore styles and tooth counts in the same product family. As a sprocket, it is intended to engage with a compatible Rexnord chain drive system to enable rotational motion transfer between a driving source and a driven component, with the keyed bore helping maintain alignment under load. This model’s precise bore size and keyed interface make it suitable for applications where a secure, non-slip shaft connection is required and where Rexnord components are specified in the bill of materials.
