What Silverthin Bearing Group does

Silverthin Bearing Group is a U.S.-based specialty manufacturer of precision thin section ball bearings and slewing ring bearings, operating as a business unit within the privately held Mechatronics Corporation (founded 1979, headquartered in Preston, Washington). The company produces thin section bearings in inch (SAA, SA, SB, SC, SD, SF, SG series) and metric (SM08, SM13, SM20) sizes across three principal architectures — Angular Contact (Type A), Radial Contact (Type C), and 4-Point Contact (Type X) — together with slewing ring bearings in rectangular, flanged, and pinion configurations, plus ceramic hybrid and specialty-coated variants. Supporting services include bearing modification (pair matching/duplexing, preload adjustment, lubrication, rolling element changes, separator selection, special widths, universal grinding), custom bearings and assemblies, and application engineering support. Pricing is quote-based and not publicly disclosed.

The company's go-to-market combines a global authorized distributor network with direct enterprise field-sales and application engineering, targeting OEM and engineering buyers in demanding end-markets — Space, Aerospace & Defense, Robotics, Medical Systems as primary verticals, and Renewable Energy, Semiconductors, Heavy Equipment, Oil & Gas, and Industrial/Machinery as secondary verticals. Its stated value proposition is weight reduction, space optimization, friction minimization, and configurability for precision motion control applications. The company employs 11-50 people, has over 40 years of bearing manufacturing experience, and operates as part of a diversified privately held parent, with no public filings, disclosed revenue, M&A activity, or leadership changes in the input record.
