Oil-free self-smooth bearing: The product is made of steel plate; the middle layer is sintered with spherical bronze powder; the surface layer is rolled with a mixture of polytetrafluoroethylene [ptfe] and lead. It has a small coefficient of conflict, wear resistance and corrosion resistance. Oil-free self-smoothing and long life characteristics; it can reduce cost, reduce noise, avoid stickiness and slip. It is widely used in various mechanical sliding parts such as printing machines, textile machines, hydraulic pallet trucks, tobacco machines, Medicinal machinery, fitness equipment, micro-motors, automobiles, motorcycles, etc.
Metal-based inlaid solid self-smooth bearing: It is a novel smooth bearing with both metal bearing characteristics and self-smooth bearing characteristics; it is loaded by metal matrix; the specially formulated solid smooth material has a smooth effect. It has high bearing capacity; Impact; high temperature resistance; self-smoothing and strong features.
Traditional oil-impregnated bearings: Because of the low sound and self-smooth strength; oil-impregnated bearings have become the new favorite of computer CPU fan bearings; the market demand is large, and others; the demand for voices is getting higher and higher; oil-bearing bearings are The use of ordinary household appliances is also expanding.
The fundamental requirement of the bearing for the data depends to a large extent on the working function of the bearing. It is appropriate to select the material for the rolling bearing; it will have a great influence on the function and life. Under normal circumstances, the primary damage of the rolling bearing is Excessive shearing under the effect of alternating stress; and loss of bearing accuracy due to conflicting wear. In addition; cracks, indentations, rust, etc. cause abnormal damage to the bearing. Therefore; rolling bearings should have high resistance to plastic deformation; Less conflict wear; outstanding rotation accuracy, outstanding scale accuracy and stability; and long touch fatigue life. And many of the functions are determined by the data and heat treatment process.

| The bearing type of the bearing block unit is a professor's trick: using the car to reduce the wear of the clutch. The bearing scale for the industrial pump and the compacting machine is re-manufactured. The gas smooth bearing is used in the machining of the bearing and the outer ring of the outer ring. |
