SERIES K DISC SPRINGS FOR USE WITH BALL BEARINGS
SERIES K DISC METRIC SPRINGS
Series K disc springs are specially designed as preloading springs for use with radial ball bearings. They help maintain positioning accuracy of the bearing with no end play. They also minimize vibration and shaft deflection. Proper preloading will increase bearing rigidly and eliminate excessive running noise.
