Typical Applications
Our self-lubricating bearings are everywhere. It can help you create a quiet and comfortable working environment. Photocopying, printers, shredders, revolving chairs, etc.
1.The rotation wheelchair Metal-Polymer Lubricated Bushes
2.Massage Armchair Metal-Polymer Lubricated Bushes
Lubrication Free with Excellent Wear Resistance
Plain Bearings & Self-lubricating Bushings
Wh it is expansion or joint position, the unleaded environmental self-lubricating sleeve of the VIIPLUS bronze bushings can be used for oil free lubrication and the damping force requirement, so that the equipment can be parked in the position you want.
Self Lube Bearings Product Category SF-2 Boundary Lubricating Bearing
Characteristics
VSB-20 Boundary lubrication bearing High Quality POM Bush China Manufacturer
· 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
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.
Strusture
1. POM thickness 0.30~0.50 mm. It provides high wear resistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.
