SKF BA 3 1 Row Ball Bearing - 3 mm ID, 8 mm OD

This thrust ball bearing provides axial load support in Compact rotating assemblies common to automation and electronics equipment. It is designed as a single-row thrust element with a ground bore and sheet-metal cage to ensure orderly ball guidance. The component is intended for miniature assemblies where axial thrust control and smooth rotation are required at high shaft speeds.

• 36,000 r/min limiting speed enables high-speed rotary usage
• 0.806 kN dynamic load capacity supports fluctuating axial forces
• 0.72 kN static load rating resists short-term high thrusts
• Sheet-metal cage maintains ball spacing for consistent operation
• Ground bore improves concentricity and simplifies mounting
• Bearing steel balls provide wear resistance under cyclic loading

• Suitable for bearing axial loads in micro gearboxes
• Ideal for precision motor end-fixings in automation
• Used with rotary encoders requiring low-profile thrust support
• Can be used for axial support in Compact electrical actuators
• Suitable for miniature pump shaft axial restraint

Contact lubrication selection should match operating temperature and speed

A finely machined ground bore promotes accurate shaft alignment and reduces run-out, which in turn lowers vibration and uneven load distribution on the raceways.

Ensure correct thrust washer or housing-face flatness to control axial play, minimal face irregularity prevents premature contact stress concentrations.

The rolling elements are MADE from bearing steel, so environmental sealing or corrosion-resistant variants should be considered for humid or corrosive atmospheres to prolong service life.
