Gamet Plain Cup Series comprises precision taper roller bearings developed for applications requiring high accuracy, controlled preload, and flexible housing arrangements. Designed and manufactured in the UK by Gamet Bearings, this series reflects the expertise of one of the world’s leading precision bearing specialists, combining advanced manufacturing techniques with proven bearing design.
Plain cup bearings feature a smooth, unflanged outer cup, allowing axial location to be controlled by the surrounding components rather than the bearing itself. This makes the series particularly well suited to machine tool spindles, gearboxes, and general industrial assemblies where accurate positioning and adjustment are required. The basic single-row bearing arrangement provides a simple and cost-effective solution for light to medium loaded applications while still delivering excellent rigidity and reliability.
The Gamet Plain Cup Series is manufactured using high-quality bearing materials and precision-ground components to ensure consistent performance and long service life. Cone bore run-out tolerances are tightly controlled, typically ranging from 0.5 microns to 1.5 microns, supporting high levels of running accuracy and smooth operation. The range covers a comprehensive selection of sizes from 25 mm bore upwards, making it suitable for a wide variety of industrial and precision engineering requirements.
All bearings are quality assured in accordance with BS EN ISO 9001:2000 standards, ensuring dependable manufacturing consistency and traceability.
Supplied by Bearing King Ltd, the Gamet Plain Cup Series provides a reliable, precise, and economical bearing solution backed by British engineering expertise and comprehensive technical support.
