Position: Home > About Us
 We believe that bigger is not always better. By keeping our product range specialised and clearly defined, we know our products well allowing us to give you a better service with excellent technical back-up. SXM Bearings originally specialised in miniature bearings, thin-section bearings and stainless steel bearings. By natural progression, we expanded the range to include other corrosion resistant bearings such as plastic bearings, 316 stainless bearings and ceramic bearings.

Our determination to remain specialised gives us a high level of product knowledge, providing bearing and lubrication solutions to existing or potential customers, whether individuals or large corporations. We don’t just sell bearings, we help to solve your problems.

EZO Agents - We are authorised distributors for Sapporo Precision of Japan who manufacture EZO brand miniature bearings, thin section bearings and stainless steel bearings. Sapporo Precision have been manufacturing small bearings for over 50 years and have a reputation for consistent quality and reliability throughout the world thanks to continuous improvement in manufacturing and quality control.

We began over 30 years ago by catering to a growing demand for micro and miniature ball bearings and expanded to include the whole of the EZO range.

Many years ago we added the SXM range of Chinese bearings to our portfolio to give customers the option to reduce costs for less demanding or price sensitive bearing applications. Now, most of our miniature bearings, stainless steel bearings and thin section bearings are supplied through either the high-precision EZO brand or the standard grade SXM brand.


During our early years, customers were often asking us to supply bearings with non-standard lubricants such as food grade, high temperature or military specification greases and oils.  Customers had been used to long delivery times or large minimum order quantities so, in response, we set up a bearing relubrication facility so that we can lubricate our bearings or our customers’ own bearings with a large range of oils, greases or dry lubricants. This facility has been recently expanded to include a new processing room and additional staff along with proprietary lubrication equipment.
