Si3N4 626 Miniature Ball Bearings Full Ceramic Bearing
The 626 bearing is a Ceramic Bearing with an inner diameter of 6 mm , an outer diameter of 19 mm, a width of 6 mm. It typically uses P0 P4 P5 P6 grade precision tolerances and open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
Si3N4 626 Miniature Ball Bearings Full Ceramic Bearing:
Features:
1, Material: ZrO2, Si3N4, SiC and Al2O3, etc.
1).High speed bearings:12000rpm--75000rpm
2).High temperature-resistant bearing:100°C--800°C.It can been applied in kiln,plastic,steel and other equipments that can bear high temperature
3).Corrosion-resistant bearings
4).Electric-insulated bearings
5).Vacuum bearings:self-lubricating without
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, increased stiffness, lower friction and more.
Ceramic bearings are available in all standard industry categories such as angular contact bearings, thrust bearing, pillow block bearing, needle roller bearings and other roller bearings.
Ceramic bearings are made from Si3N4 which have greater hardness than steel.
Ceramic bearing balls have smoother surface than most steel bearings balls.
They require less lubricant and exhibit lubrication degradation, which results in increased bearing life.
Ceramic bearings are applied on high temperature, high speed, friction, semiconductor and food processing and so on.
Application:
Full ceramic bearing could be used in following industries: chemical, semi-conductor, valve & pump, food, electronic, medical, vacuum, refining, insulation, etc.
Note:
Full ceramic bearing is not suitable for heavy loading, impact loading and variable loading application.
