HK3520 Drawn Cup Needle Roller Bearing (35mm x 42mm x 20mm, Open Ends)

Model: No Seal

Product Highlights

Standard metric dimensions (35mm Fw x 42mm OD x 20mm Width) providing high radial capacity in tight spaces
Deep-drawn, thin-walled outer ring allows extreme compactness where housing bores cannot be used as raceways
Precision-ground GCr15 chrome steel needle rollers ensuring uniform load distribution and low vibration
Rigid stamped steel cage guides rollers accurately for smooth high-speed rotation and low operating torque
Exceptionally high dynamic (26.5 kN) and static (49.5 kN) radial load ratings
Open-end design enables easy through-flow lubrication with standard mineral oils or greases
Press-fit mounting design requires no axial shoulders or snap rings for retention
Plná shoda s environmentálními směrnicemi RoHS a REACH ve všech výrobních procesech
