Gamet Constant Preload Bearings are precision-engineered bearing solutions designed to maintain a stable and consistent preload in high-accuracy machine tool and industrial applications. Manufactured in the UK by Gamet Bearings, these bearings are developed to deliver reliable rigidity, positional accuracy, and repeatable performance under varying operating conditions.

The constant preload arrangement is based on a single-row bearing with an extended outer ring that houses a number of precisely calibrated springs. This bearing is mounted in conjunction with either a single-row or double-row bearing to form a complete bearing system. The outer race is free to slide within the housing, allowing the spring force to act continuously on the bearing set.

As operating temperatures change and thermal expansion occurs within the shaft and housing, the spring-loaded outer ring compensates automatically for these dimensional variations. This ensures that a constant bearing system preload is maintained at all times, preventing loss of stiffness, excessive preload, or positional drift. The result is reduced vibration, consistent running accuracy, and improved surface finish in precision machining operations.

Gamet constant preload bearings are commonly used in machine tool spindles, grinding machines, and other high-precision assemblies where stable axial positioning and long-term accuracy are essential. Manufactured to tight tolerances using high-quality bearing materials, they offer smooth operation, low run-out, and dependable performance, making them a proven solution for demanding precision engineering applications.
