Metal-Polymer Plain Bearings Grease Lubricated, 

Metal-Polymer Composite Bushing Material

Steel Back + Porous Bronze Sinter +POM with Lubrication Indents Bearings Supplier & Bushing

Material-Characteristics

Steel with porous sintered tin bronze layer, which is coated with POM as sliding layer. The POM sliding layer contains grease pockets, which serve as a lubricant reservoir. Suitable for grease and oil lubrication

• DX marginally lubricated bushings for grease or oil lubricated applications
• Standard parts contain grease indents in the sliding layer; plain sliding layer available by request
• Optimum performance under relatively high loads and low speeds
• Suitable for linear, oscillating and rotating movements
• Wide range of parts available from stock

Article Description: Dx bush

Why choose dx composite bearing?

• Maintenance-free operation

• No lubrication required (PTFE composite)

• Initial lubrication required (POM composite)

• Minimum wall thickness, minimum space requirements

• Accommodation of heavy loads

• Wide range of temperatures

• Good sliding properties

• Virtually no stick-slip

• High wear resistance

• Less sensitive to edge loading (POM composite)

• No machining required.
