SKF K 30X35X13 30 mm ID Roller Bearing Needle, 35 mm OD

This roller bearing provides a compact, single-row solution for radial load support in rotating assemblies. It is a needle-style roller and cage assembly intended for mechanical and automation equipment where a round bore and slim envelope are required. The component is delivered as a sheet steel-caged set of rollers suited to high-speed rotating shafts and housings.

• Dynamic capacity 15.1 kN enables sustained radial load cycling
• Static capacity 25.5 kN resists high standstill loads
• Limiting speed 15,000 r/min supports high-speed usage
• Cage MADE from sheet steel reduces centrifugal deformation

• Suitable for servo motor shaft support in automation
• Ideal for gearbox intermediate shafts in robotics
• Used with precision actuators in electronics assembly
• Can be used for spindle support in electrical equipment

Design guidance covers shaft and housing tolerances and radial internal clearance to ensure correct preload and running behaviour for needle roller assemblies.

The needle roller and cage assembly mass is 0.014kg which minimises added inertia for responsive servo and high-speed systems.

Selection and lubrication can be supported by specialist calculation and grease selection tools referenced for engineering use, including bearing selection and speed calculators.

A reference speed of 13,000 r/min and a limiting speed of 15,000 r/min provide practical constraints for thermal rise and lubrication regime planning.
