Hydraulic pump special self-lubricating bearing bushing, It’s also called oil-free bushes, plain sliding bearing, bushes, PTFE bushes.
Self-lubricating bearings & Flat Bushings have always been our main products, in which the second layer of the composite bushing is made of bonded composite antifriction and wear-resistant materials.
Self-lubricating bearings have a number of series, including metal backing rolling series, metal mesh backing rolling series, metal backing bonding series and another relatively complete material system, and according to customer requirements to develop and transform the new material system. These materials are suitable for making shaft sleeves, bushings, gaskets, guide rails, sliding plates, and joint bearings, and other mechanical parts, which have been widely used in automobiles, general machinery, household appliances, and aerospace machinery.
One of the suppliers of high-quality self-lubricating bearings, custom size complex bearing bushing parts, is your good choice.
The use of composite self-lubricating materials, to achieve the real sense of green energy saving
The company uses composite self-lubricating materials, the benefits of this innovative process lies in: environmental protection production process, low energy consumption, high production efficiency, energy saving, environmental protection and green manufacturing.
Plain bearings, bushings & sleeves – metric size
Bonded composite self-lubricating plate can be used under interference conditions
Can eliminate the gap, play a role of shock, noise elimination, self-lubrication, in the material strength is better than the metal mesh belt, the use of a wider range of conditions, lower cost, more environmentally friendly process.
