NU310 Ceramic Roller Bearing Of Si3N4 Races And Rollers+PEEK Cage
Description of NU310 (Si3N4 races and rollers+Peek cage):
1. Si3N4 races and rollers: Are made of highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, and is processed by GPS (Gas Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology.
2. Peek cage: Peek has high temperature resistance ( can work long time at 260 degrees) excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, peel resistance, wear resistance, not strong nitric acid, concentrated sulfuric acid, radiation resistance, super mechanical properties can be used in high-end machinery, nuclear engineering and aviation science and technology.
Performance advantages of NU310 (Si3N4 races and rollers+Peek cage):
► Key properties of hot isostatic sintered silicon nitride |
♦ Max temperature to 1000℃ |
♦ High strength over a wide temperature range |
♦ High fracture toughness: 6.1 MPa-m1/2 |
♦ High hardness: 1580 HV5 |
♦ Outstanding wear resistance, both impingement and frictional modes |
♦ Good thermal shock resistance |
♦ Good chemical stability,resistance to acid and alkali corrosion |
♦ Good electric insulation |
