What SMB Bearings does

SMB Bearings is a privately held specialist bearing distributor founded in 1991 and headquartered in Carterton, Oxfordshire, United Kingdom. The company supplies precision miniature bearings (shaft sizes from 0.6mm to 80mm bore), offered in multiple materials including chrome steel, 440 and marine grade 316 stainless steel, acetal/POM-C, PEEK, PTFE, PVDF plastics, and full ceramic options in zirconium dioxide (ZrO2) and silicon nitride (Si3N4). Products are sold in both metric and imperial sizes across categories such as miniature, ceramic, thin section, thrust, extended inner ring, taper OD, skate, and electric motor (EMQ) bearings. SMB Bearings is the authorized UK distributor for EZO brand bearings manufactured by Sapporo Precision of Japan, and the EZO relationship is described as central to the product offering. In addition to distribution, the company operates an in-house bearing relubrication facility providing cleaning, degreasing, and bespoke re-lubrication of SMB or customer-supplied bearings with specialist lubricants for specific torque, rotational resistance, or custom requirements. All products are RoHS compliant under EU Directive 2011/65/EU.

The business operates from a single UK warehouse with no trade counter (visitors by appointment only) and ships worldwide. Distribution is direct-to-customer via phone (+44 (0) 1993 842 555) and email, with no published pricing and quote-based ordering. Marketing is limited to a content-rich company website covering technical resources, downloadable catalogs, and an extensive set of application pages spanning instrumentation, marine, food and beverage, chemical/pharmaceutical, vacuum/cleanroom, aerospace and drones, robotics, fishing reels, automotive, bicycles, clocks, skateboards, agricultural, and industrial uses. The horizontal segmentation approach targets a long-tail of niche B2B and hobbyist buyers rather than any single anchor vertical. Pricing is opaque and order-based, consistent with low-volume, high-touch specialty distribution.

The company is led by Managing Director Chris Johnson. There are no disclosed external funding rounds, parent companies, subsidiaries, or material M&A activity. Headcount is stated at 1-10 employees, indicating a micro-distribution operation. The revenue model is one-time product sales of physical bearings plus service revenue from relubrication, with no subscription or recurring software component.
