Bearing alloys: mainly tin, lead, antimony, or other metals, also known as white metal roll bearings alloy. Because of its good wear resistant, high plasticity, ran together good performance, good thermal conductivity and resistance to rubber and oil resistance and good absorption and therefore suitable for heavy, high-speed case, the bearing strength of the alloy, low price expensive, use must be cast in bronze, steel or cast iron bearing, to form a thin coating.
1, plastic bearings: plastic bearings have greater compressive strength and wear resistance, commonly used bearings Plastic Bakelite, nylon, PTFE and so on. Lubricating oil and water are available, but also a self-lubricating properties, but poor thermal conductivity.
2, the porous metal material: a porous tissue, the porous metal material is a powder. If it is immersed in lubricant, allowing the pores filled with oil, into oil bearing, self-lubricating properties. Porous metal material toughness is small, only suitable for stationary and non-impact load, the low-speed situations.
To improve the sliding performance and life of the bearing, bearing information should choose these factors into account. Bearings and bearing liner information collectively referred to as bearing materials, bearing wear and journal information, bearing their own materials, lubricants and lubrication directly related.
