BK12 Model Ball Screw Bearing, 12mm Inner Diameter

The BK12 ball screw bearing is a critical component in industrial systems, especially in CNC machinery and industrial automation. This primary ball screw support bearing, with a 12mm inner diameter, is designed to deliver optimal performance and high precision in transferring linear and rotational motion. The BK12 ball screw bearing is specifically engineered for use with ball screw systems and is installed at both ends of the ball screw. This primary ball screw support not only acts as a holder for the screw but also restrains lateral and longitudinal movement, allowing only rotational motion.

The BK12 ball screw bearing employs high-strength, low-torque angular contact bearings in the primary section, which ensures precise and smooth shaft rotation. The secondary section utilizes deep-groove 6000-series bearings that prevent oil and dust from entering the bearing.

This industrial bearing, with its excellent quality, is particularly suitable for high-precision industries requiring exact performance, such as CNC machinery and industrial automation systems. With its unique design and precise engineering, this component can meet the needs of designers and equipment manufacturers while guaranteeing optimal performance under various operational conditions. Brands such as Hiwin and HQM are well-known in the production of industrial ball screw bearings.

The industrial ball screw bearing, also known as CNC support, is widely used in CNC machines to hold and stabilize ball screws. This feature enhances accuracy and reduces potential vibration and play in ball screw systems, ultimately improving the performance of industrial machinery.
