Self-lubricating multilayer composite bearing JX-SF-1-2238

Metal-Polymer Composite Material.Bronze Back + Porous Bronze Sinter + PTFE.Trusted & Reliable Bronze Backed Bushing.Rolled composite plain bearings according to DIN 1494 / ISO 3547
Bronze / PTFE sliding layer Maintenance-free High chemical resistance
Maintenance/lubrication. Lubrication is not required because of dry plain bearings with a PTFE sliding layer. However, additional lubrication is possible.    

Light Duty Dry-Running Sleeve Bearings. Use where high loads and speeds are not required. MDS-filled nylon bearings create less friction than standard nylon bearings, making them more wear-resistant.
Acetal bearings have low moisture absorption and are more chemical resistant than nylon and MDS-filled nylon bearings.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.    

PV value is an effective criterion to calculate the service life of Self-Lubricating Multilayer Composite Bushing. If there is a need to prolong the service Life, the PV value must be reduced.2). Ambient Temperature.The higher the working temperature is, the shorter the life of the products would be.3). Quality of the Mating Surface
Service life Self-Lubricating Multilayer Composite Bushing can be prolonged if its mating axis is made of alloy steel or is plated by hard chrome and with surface Roughness Ra=0.4~0.63.
