Rubber coated steel bearing balls

Shore hardness is 90. 
Specifications: φ15, φ20, φ30
Specification and size of rubber-coated steel ball: 9-10-12.7-15.5-18-20-22-24-29mm
Coating material: silicone, polyurethane, rafter, nylon
Polyurethane steel ball, polyurethane coated steel ball
Polyurethane plastic, known as the "wear-resistant king", is an innovative multifunctional material with excellent comprehensive properties.
1. Excellent abrasion resistance;
2. The hardness range is wide and adjustable (10A to 73D);
3. Adaptation temperature -40℃ to +80℃;
4. Good tear resistance and high bending strength;
5. Large tensile strength and elongation at break;
6. Good elasticity, the shape becomes smaller after long-term compression;
7. It is resistant to oil and organic solvents, which is better than nitrile rubber;
8. Excellent aging resistance.
