R188 Stainless Steel Hybrid Ceramic Bearings For Fishing Gear
Stainless steel hybrid ceramic bearing special high-quality hybrid ceramic bearing for fishing gear
FreeRun is a specialized manufacturer of Hybrid Ceramic Bearing,Full Complement Ceramic Bearings & Ceramic Balls.
Ceramic bearings offer a significant performance improvement from those made from traditional steel. Our ceramic bearings are manufactured from silicon nitride (Si3N4), an exceptionally hard non-metallic material rated for speeds to 2 million dN, offering a wide selection of benefits.
In very high speed applications, heat from friction during rolling can cause problems for metal bearings, which are reduced by the use of ceramics. Ceramics are also more chemically resistant and can be used in wet environments where steel bearings would rust. In some cases, their electricity-insulating properties may also be valuable in bearings.
Ceramic Balls:
We are special in making Silicone Nitride Balls (Si3N4 Balls), Zicronia Balls (ZrO2 Balls),Sic Ceramic Balls, Aluminum Oxside Valve (AI203) ceramic balls.
Compared with steel, ceramic materials are noted for their better or particular characters, such as wear-resistance, corrosion resistance, high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
