Under Severe Operating Conditions
DX POM Coated Bushing have been specially developed for marginally lubricated applications and so can function for long periods with minimal lubrication.
Main advantages of DX POM Coated Bushing include:
• Minimal maintenance
• High sliding velocity
• High load
• Low friction coefficient
• Minimal bearing play
DX POM Coated Bushing are made from a steel backing to which a sintered bronze layer is applied. A POM top layer is then applied to this bronze layer. The bronze intermediate layer ensures efficient heat dissipation and makes for a strong joint between the steel backing and the sliding surface.
The steel backing is provided with a layer of copper or tin to prevent corrosion, while the POM top layer incorporates grease pits to retain the lubricant.
DX POM Coated Bushing are specially suited to severe operating conditions where frequent maintenance is not possible.
Common applications are:
• Hydraulic applications
• Mechanical engineering
• Construction machinery
We recommend that DX POM Coated Bushing are lubricated with grease. The grease must contain an antioxidant for environments with temperatures over 50oC. Greases containing EP additives or significant amounts of graphite or MoS2 are not generally recommended.
Lubricating with oil is only advisable with applications in which the oil temperature does not exceed 70℃。
