Ball Bearings

high speed ceramic ball bearing (Si3N4)

ceramic bearing with good quality and high speed, at reasonable price. Quick delivery, good service, all sizes available. We supply a comprehensive range of ceramic bearings.Ceramic bearings usually weigh 40% less than ball bearings and roller bearings for its size and material.Ceramic bearings are typically constructed with a ferrous inner and outer ring with ceramic balls in stead of steel.They takes many advantages over steel bearings, such as higher speed and acceleration capability,

High Precision Si3N4 (Silicon Nitride) Ceramic Bearings

**SI2N4 **ZrO2 **SSIC Si3N4 (Silicon Nitride) Ceramic Bearings The ultimate hub has to have the ultimate bearings. Silicon Nitride (Si3N4) ceramic bearings are 30% lighter than steel and 40% stronger. So finely balanced, they have an incredible maximum spin rating of 300, 000 rpm under load. Manufactured in matched sets of 15 balls per cartridge, they exhibit variance in size and sphericity of LESS than 2 millionths of an inch among the entire bearing set.

High Speed Si3N4 Ceramic Bearing

Low density: Due to low density, ceramic bearings have low centrifugal load and create little heat, so they can work in the conditions of higher speed Rational elastic ratio: The elastic ratio of ceramics is higher than that of steel, thus increasing bearing's dynamic stiffness, however, the elastic ratio should not be too high, otherwise, excessive elastic ratio will create stress concentration to decrease the bearing capacity Low thermal expansion:

608 Full Ceramic Bearing (Si3N4)

Full Si3N4 bearing has some better performance than ZrO2, the rings and balls made by full ceramic material: Si3N4, as a standard constructure, the cage made by PTFE, generally we also could make the cage with GFRPA66-25, PEEK, PI, Phenolic Textolite Tube, etc. Compares than the material of ZrO2, The SiN4 ceramics bearings could endure heavier load and could be used in higher temperature environment.
