Schaeffler Series HK Roller Bearing, 20mm Race Width, 35mm Inside Diameter - HK3520-B


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.

Features and Benefits:


• 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

Applications


• 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

What bearing end configuration does it use?


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

How many rows of rollers are included and what advantage does that offer?


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

What are the limiting rotational speeds for different lubricants?


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

What bore geometry should the mating shaft present?


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

What are the primary load ratings relevant to selection?


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