Inch Size Miniature Ball Bearings

Inch size miniature ball bearings are small rolling-element bearings measured in imperial units, commonly used in precision instruments and small-scale machinery.

Dimensions Based on the Inch Size

Compared with the more common metric miniature bearings, the inner diameter, outer diameter and width of the inch size miniature ball bearings strictly follow the imperial system (inches) standards. This design concept ensures that their manufacturing process is centred around inch size units, which is particularly important for equipment that is designed or maintained using the inch size of dimensions.

Therefore, choosing inch size miniature bearings as substitutes or new design solutions for this equipment is very appropriate. This not only ensures the interchangeability and compatibility of components, but also effectively avoids the additional design or processing costs and complexity caused by size mismatch.

Designed for Tight, Precise Spaces

The most notable feature of this type of bearing is its miniature external dimensions. Despite being measured in imperial units, the overall size is very compact.

This miniaturised design enables them to be easily integrated into precision machinery and electronic devices where space is extremely limited.They provide essential rotational support in applications such as precision instruments and meters, medical equipment, small motors, automation components, hard disk drives, cameras, and various models and toys, all while maintaining a compact size.

Handles Radial and Moderate Axial Loads

Inch size miniature ball bearings typically adopt the internal structure of deep groove ball bearings. This design enables them to effectively withstand radial loads mainly acting perpendicularly to the bearing center. Although their axial load-carrying capacity is usually lower than that of specially designed thrust bearings, in many miniature applications, the simultaneous presence of radial and moderate axial loads can be met by such high-quality bearings.

This comprehensive load-carrying capacity makes them exhibit good versatility in compact applications where they need to support rotational motion and resist certain axial forces at the same time.

FREQUENTLY ASKED QUESTIONS

What materials are available for Inch Size Miniature Ball Bearings?

Common options are 52100 Chrome Steel (strong, cost-effective, needs protection from moisture) and 440C Stainless Steel (resists corrosion, ideal for damp environments)

What is the general size range for Inch Size Miniature Ball Bearings?

These are "miniature," typically meaning the outer diameter (OD) is under 0.5 inches (12.7mm). However, specific sizes vary greatly within this category.

Can I replace a metric miniature bearing with an inch one?

Generally, no. Inch and metric bearings have different standard dimensions. Direct replacement is usually not possible unless sizes are nearly identical and your application's tolerance allows it.

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.
