Miniature Angular Contact Ball Bearings

Super precision angular contact ball bearings are engineered for high-speed, high-accuracy applications such as machine tools, aerospace systems, and robotics.

Combined Load Capacity in Tiny Sizes

Miniature angular contact ball bearings are specifically designed to handle both radial and single-direction axial (thrust) loads simultaneously, even within extremely small bearing dimensions.

This dual capability makes them perfect for compact applications where space is critical, but load conditions are complex, such as in small medical devices or precision robotics.

Choose these when you need more than just radial support in a micro bearing footprint.

Suitable for High-Speed Miniature Applications

Despite their small size, miniature angular contact ball bearings can often operate at relatively high speeds.

Their precise construction and quality materials allow for smooth operation at higher RPMs, compared to other bearing types of similar dimensions, making them suitable for components like small high-speed motors, dental handpieces, or micro-spindles.

Space-Saving Micro Bearing Design

The “miniature” aspect means these bearings have very small bore sizes, outer diameters, and widths, often falling into the micro bearing category.

This allows designers to significantly reduce the size and weight of their assemblies. If you are working within extremely tight space constraints and need reliable combined load support, these miniature angular contact ball bearings are the ideal solution for achieving miniaturisation goals.

FREQUENTLY ASKED QUESTIONS

Why do I need to use these miniature angular contact bearings in pairs?

A single bearing only supports axial load in one direction. Using a pair allows support for bidirectional axial loads and proper preloading, crucial for rigidity and preventing ball skidding in angular contact bearings.

Are chrome steel options available for these small bearings?

Yes, many miniature angular contact ball bearings are offered in chrome steel. Due to its excellent hardness, wear resistance, contact fatigue strength and cost balance, it is widely used in various mechanical systems.

Check product detail pages for material options.

When should I choose these over miniature deep groove bearings?

Choose miniature angular contact bearings when you have significant axial loads alongside radial loads, require higher system rigidity, or need better running accuracy than standard miniature deep groove bearings can offer.

Do you offer samples? What is the Minimum Order Quantity (MOQ)?

Sample availability and Minimum Order Quantity (MOQ) can vary by product model. Please check the specific product page or contact our sales team for details on the bearing you need.
