Now we use the self aligning ball bearing variety, each of which has its common use, not mixed, self aligning ball bearing plastic and metal self aligning ball bearing with the most self aligning ball bearing, then the plastic and metal self aligning ball bearing what is the difference? Let Shandong kayyou self aligning ball bearing limited to inform you.
The use of self aligning ball bearing now can be divided into self bearing and ball aligning over self aligning ball sliding bearing; self aligning ball bearing the work principle of rolling and sliding self aligning ball bearing the title can be difference apart, self aligning ball bearing with rolling operation is rolling and sliding self aligning ball. Bearing operation occurs when the sliding resistance force; rolling resistance mainly depends on manufacturing precision; and self aligning ball bearing with sliding force of composite self aligning ball bearing self aligning ball bearing depends primarily on the sliding surface material. Sliding self aligning ball bearing has self-lubricating function on the general working surface; sliding self aligning ball bearing is divided into non-metallic sliding self aligning ball ball and metal sliding pin, respectively, according to the material.
Self aligning ball bearing non metal sliding self aligning ball now mainly in the plastic bearing, self plastic aligning ball bearing are generally selected function of engineering plastic sleeve; comparison of professional manufacturers generally have the self lubrication engineering plastics modification technology by fibers, special lubricants, glass beads and so on of engineering plastics lubrication reinforced modified to make it to certain function, and then use the modified plastics into self-lubricating plastic self aligning ball bearing. by injection molding
Self aligning ball bearing metal sliding now use the most is the three layer self aligning ball bearing self aligning ball bearing, which is generally based on carbon steel substrate by sintering technology in steel plate on the first layer of spherical copper powder sintering, and then on the copper layer on the sintering of PTFE lubricant layer is 0.03mm; the center the first is to enhance the effect of spherical copper layer bonding strength between steel plate and PTFE, in the course of the operation also has certain bearing and lubrication.
It is not difficult to see that there are the following differences between the plastic self aligning ball bearing and the metal sliding self aligning ball bearing through the above description:
1, self aligning ball bearing plastics are all lubrication materials, using his long; and self aligning ball bearing metal sliding lubrication layer is only the surface of 0.003mm PTFE, when a thin layer of conflict after using his declared end;
2, plastic self aligning ball bearing will not rust and corrosion-resistant in operation, while metal self aligning ball bearing is easy to rust and can not be used in chemical solution.
3, the quality of the plastic self aligning ball bearing is lighter than the metal, which is more suitable for the modern light weight planning trend.
4, the manufacturing cost of plastic self aligning ball bearing is lower than that of metal products. Plastic self aligning ball bearing is made by injection molding, and is suitable for mass production.
5, the plastic self aligning ball bearing has no noise in the work, and has a certain absorption function.
Because there are many advantages of the self aligning ball bearing plastic metal sliding self aligning ball bearing self aligning ball bearing, now the plastic production is growing, self aligning ball bearing plastic applications has been extended from fitness equipment to office equipment and car industry and so on are chosen by self aligning ball bearing plastic. Now travel on the road car without the use of plastic self aligning ball bearing. Plastic self aligning ball bearing market prospects are unlimited!
