FREQUENT Q/A

What are the plastic bearings?

SINO BEARINGSAug 02, 2022
1. Precision plastic bearing
 
Precision plastic bearing, compared with the traditional plastic bearing precision and tolerance improved. Generally, inner and outer rings, rolling bodies and cages are made of materials suitable for precision machining. On the basis of maintaining the traditional advantages of plastic bearings, they can be used for precision and relatively high speed operation. Usually the inner and outer ring materials are POM, PPS, or PEEK, the cage is made of fiberglass reinforced nylon 66(RPA66-25), or PEEK, and the rolling body is glass ball, stainless steel ball or ceramic ball.
 
2. Anti-corrosion plastic bearing
 
There ARE a variety OF MATERIAL SOLUTIONS FOR different USE situations, which can operate smoothly even in the harshest acid/alkali/salt/solvent/oil/gas/sea water erosion, ensuring ideal durability and life expectancy.
 
3. Acid and alkali resistant plastic bearing
 
Hdpe, PE, UHMWPE materials have been proved to be used in relatively weak acid-base cross environment (30% CUCL2 solution and 30% NaOH solution test OK), strong acid and strong base environment can be used PVDF and PTFE materials, including PTFE can be used in all concentrated acid and alkali occasions, including HF and fuming sulfuric acid nitric acid (more than 98%) And so on.
 
4. High temperature resistant plastic bearing
 
PVDF, PTFE (TEflon), PPS (polyphenylene sulfide), PEEK (polyether ether ketone), PI (polyether imide) and other proved to be the ideal material for the production of high temperature plastic bearing, PI can be used in the long-term temperature of 290℃ environment, short-term temperature resistance can reach 350℃. It is one of the best high temperature properties of all known engineering plastics.
 
5. Plastic bearing seat and plastic outer spherical bearing
 
Plastic belt bearing unique light weight, easy installation, corrosion resistance, free from maintenance, in addition to the common cast iron seat or stamping seat does not have the vibration and impact resistance.
