定义
A specialized rolling-element bearing engineered to support axial loads parallel to the shaft axis, specifically used in screwdown mechanisms of industrial machinery to convert rotational motion into precise linear force application while maintaining alignment and minimizing friction.
工作原理
Operates by distributing axial forces across multiple rolling elements (balls or rollers) arranged perpendicular to the shaft axis, allowing relative rotation between shaft and housing while preventing axial displacement through precise raceway geometry and preload mechanisms.
材料
Bearing rings: AISI 52100/100Cr6 steel (HRC 58-62)Rolling elements: AISI 52100 steel (HRC 60-64)Cage/retainer: Brass (CuZn39Pb3) or polymer (PEEK/PA66)Optional coatings: Black oxide or zinc phosphate for corrosion resistance.
Clearance
C3/C4 (ISO 5753)
Lubrication
Grease (NLGI 2) or oil bath
Speed Rating
Up to 3000 rpm
Load Capacity
50-500 kN static, 30-300 kN dynamic
Precision Class
P5/P6 (ISO 492)
Temperature Range
-30°C to +120°C
标准
ISO 104DIN 711DIN 715ISO 199ISO 492

常见问题

What is the main function of a thrust bearing in screwdown mechanisms?

To absorb and manage axial forces generated during screw operation while maintaining precise positioning and preventing shaft displacement.

How do thrust bearings differ from radial bearings?

Thrust bearings are designed specifically for axial/parallel loads, while radial bearings handle perpendicular loads; thrust bearings have raceways perpendicular to the axis.

What maintenance is required for thrust bearings in screwdown applications?

Regular lubrication replenishment, clearance monitoring, contamination prevention, and periodic inspection for wear patterns and preload maintenance.
