608 Zirconia Ceramic Bearing Lifespan Long 8x22x7mm
ZrO2 Ceramic Bearing 608-2TS With High Precision
Description of 608-2TS:
1. ZrO2 Races and Balls:Are made by highly purified, sub-micron and after Y2O3 partially stabled zirconia powder material and are sintered by HIP (Hot isostatic pressure) technology and ground by our automatic machine.
2. Peek cage: PEEK has more significant advantages compared with other special engineering plastics. Positive high temperature 260 degrees, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, peel resistance, wear resistance, resistance to strong nitric acid, concentrated sulfuric acid and so on.
3. seals: has excellent chemical stability, corrosion resistance (is one of the best corrosion resistance materials in the world today. The seals in this material can resistant to many corrosion operating situation.
Properties of zirconia material:
| ♦ Max Temperature up to 380℃ |
