Metal-Polymer Composite Bearings

JBM-FR

Bronze Mesh + PTFE/Solid Lubricants

PRODUCT OVERVIEW

Features & Benefits

The JBM-FR features a unique composite design consisting of a bronze mesh shell integrated with a PTFE and solid lubricant filler. This flexible structure is engineered for ease of assembly, ensuring excellent fitment particularly in hinge applications. It delivers reliable performance by maintaining consistent torque levels across a wide range of operational conditions.

MATERIAL COMPOSITION
