Metal-Polymer Bearings
DS
Metal-Polymer Self-Lubricating Bearings
CHARACTERISTICS
- Self-lubricating bushings for operation in mixed film lubrication conditions
- Sliding layer is machinable (ca. 0.4 mm above bronze sinter layer)
- Resistant to fretting corrosion damage to the shaft under low amplitude oscillating movements
- Similar in performance to DX® but with lower friction
Bearing forms available in standard dimensions
Cylindrical bushes 
Flanged bushes
Thrust washers 
Sliding plates
Bearing forms made to order: cylindrical bushes, thrust washers, sliding plates, half-bearings, special shapes obtained by stamping, customized bearing designs
STRUCTURE AND COMPOSITION
