Bearing Families Mapped to Machine Duties
Which precision bearing family fits which German and Swedish machine duty, and why. Every family is matched to a real duty cycle, then specified by tolerance class, steel grade and mounting method so a buyer can compare directly.
Machine Tool Spindles
P4 spindle bearings to ISO 492 hold runout below 0.001 mm under 10,000–24,000 rpm; 100Cr6 steel with matched preload suits high-speed finishing lathes.
Robotics Joint Actuators
Angular contact ball bearings in robot joint reducers take radial and axial load together, with light inertia and service life matched to cyclic stop-start duty.
Printing Press Rollers
Cylindrical roller bearings support oscillating and rotating print rollers, with low friction and stable preload across long press runs.
Pumps and Hydraulic Units
Cylindrical roller bearings handle high radial load with low speed in piston and gear pumps; sealing and clearance set to the medium.
Wind and Material Handling Drives
Tapered roller bearings in gearbox and conveyor drive lines cope with shock loads, misalignment and contamination, with adjusted internal clearance.
Feed and Drive Rollers
Compact precision bearings for feed rollers and auxiliaries run at high speed with minimal noise, sized to shaft and housing dimensions on the drawing.
