The ball trains have a 45° contact angle, enabling equal load distribution in radial, reversed radial, and lateral directions, making them suitable for any installation direction. The MSA series provides balanced preload for increased rigidity in all directions while maintaining low friction, ideal for high-precision, high-rigidity motion. The patented lubrication design ensures even lubricant distribution, optimizing lubrication in any installation direction, enhancing running accuracy, service life, and reliability.
