JBM-12

Steel with PTFE Tape

JBM-12 product
PRODUCT OVERVIEW

Features & Benefits

The JBM-12 is engineered for applications requiring a lightweight, simplified bearing structure. Its versatile design facilitates easy assembly—supporting both manual and automated press-fit methods. The material is available in thin-wall configurations for space-saving efficiency, as well as thick-wall options that allow for post-assembly resizing to achieve superior mating accuracy. Suitable for both clearance and interference fits, the thick PTFE tape layer ensures excellent dry-running performance while effectively dampening operational noise.
