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