INA HK3520-B 35 mm ID Roller Bearing Drawn Cup Needle, 42 mm OD

This roller bearing is a drawn cup needle roller component designed for applications requiring Compact radial support in rotating assemblies. It features an open end and a single-row arrangement, providing low cross-section rolling support where space is limited. The bearing is intended for installations that need a parallel bore Interface and a sheet steel cage to retain rollers, operating across oil- and grease-lubricated conditions at elevated shaft speeds.

• Sheet steel cage retains rollers and reduces internal friction
• Supports a dynamic load of 23800 N for operational resilience
• Withstands static loads up to 46000 N for high contact stress
• Permits grease lubrication at sustained 4500 r/min
• Accepts oil lubrication at elevated 7500 r/min
• Parallel bore design for straightforward shaft mounting

• Suitable for Compact transmissions with limited radial space
• Ideal for industrial gearboxes requiring high static capacity
• Used with low-profile shafts needing parallel bore interfaces
• Can be used for high-speed rotating shafts in oil-lubricated systems
• Suitable for maintenance scenarios favouring grease-lubricated bearings

It has an open-end design allowing axial insertion of the shaft.

It uses a single row of needle rollers which minimises radial cross-section.

The limiting speed under oil is 7500 r/min and under grease is 4500 r/min.

The mating shaft must provide a parallel bore Interface for correct seating.

The dynamic load rating is 23800 N and the static load rating is 46000 N.
