Bearing manufacturer: what are the types of bearing?
Currently used bearings manufacturers generally can be divided into rolling bearing and sliding bearing;
The working principle of rolling bearing and sliding bearing can by name can distinguish, rolling bearing rolling friction is the friction at work, and sliding bearing work happens when sliding friction;
The rolling friction is mainly depends on the size of the manufacturing accuracy;
And the size of the sliding bearing friction is mainly depends on the slip plane of the bearing material.
Commonly used are: 1, acetal bearing materials: the material price is the lowest, it to the dynamic and static friction factor of steel is very low, the strength and stiffness is higher also, commonly used to manufacture the outer box under light load;
2, nylon bearing material: material is a kind of low price and low friction factor, the self lubrication is stronger, often adding graphite, molybdenum disulfide and ptfe packing, in order to increase the embellish sex, strength and stiffness, working temperature is 120 ℃;
3, ptfe bearing materials: minimum friction factor, and when the load increases, the friction factor decreases, often adding glass fiber, graphite, bronze powder to improve the performance indicators, such as working temperature is higher;
4, phenolic bearing material: high strength, high temperature resistance, but the friction coefficient is bigger, wear faster, for packing with ptfe resin, to reduce friction factors and improve the life (
