Glass Ball Manufacturer Introduces The Advantages Of Plastic Balls In Plastic Bearings For Turntables

Update:15 Apr 2021

The plastic ball materials for slewing bearings mainly include POM (polyoxymethylene plastic balls), PA (nylon plastic balls), PTFE (Teflon plastic balls), PEEK plastic balls, etc. The plastic slewing bearing requires that the plastic ball bearing pressure is below 200kg, Plastic ball accuracy requires a diameter tolerance of ±0.001. Below, Glass Ball Manufacturermainly introduces the advantages of several plastic balls in turntable plastic bearings.

1.POM plastic ball (polyoxymethylene plastic ball), with high hardness, good surface finish, non-absorbent, can work in high humidity environment for a long time, temperature resistance is between minus 30 degrees and above zero, no need Lubricating oil has a long service life, and its impact resistance is slightly weaker than nylon plastic balls.

2. PA plastic ball, high hardness, good toughness, strong impact resistance, good surface finish, no lubricating oil, strong high-temperature resistance, can be used between minus 40 degrees-150 degrees above zero and has a long service life.

3. PEEK plastic ball has high strength, good toughness, and high hardness. It is the plastic ball with the best high-temperature resistance among plastic balls. It can withstand high temperatures above 200 degrees, but the material cost is high, and it is difficult for ordinary customers to accept PEEK plastic balls. The price of the bearing.
