Roller Bearings
Compact high-capacity bearings for restricted radial space.
HK · NK · RNA · AXK · KROverview
Roller bearings deliver high load capacity in minimal radial space — drawn-cup (HK), machined-ring (NK/RNA), thrust (AXK) and stud-type track roller (KR) designs cover gearboxes, transmissions, pivots, cam drives and compact machinery.
Key Features
- Highest capacity-to-size ratio
- Drawn-cup and machined types
- With or without inner rings
- Thrust series available
