234412-M-SP

The 234412-M-SP is a double-direction axial angular contact ball bearing, engineered to meet the highest standards of precision required in demanding applications. Specifically designed for the main spindles of machine tools, this bearing provides extremely accurate axial guidance. With a 60 mm bore, 95 mm outside diameter, and 50 mm width, its compact, high-rigidity design is optimized for environments where rotational accuracy and stability are critical. The "SP" designation signifies Super Precision, ensuring the tightest tolerances for runout and dimensional accuracy, which is fundamental for high-quality machining operations.

This super precision bearing features a two-piece inner ring and a solid brass, window-style cage (M designation), which offers superior strength and stability at high rotational speeds. The 60° contact angle is specifically configured to accommodate very high axial loads from both directions while providing exceptional system rigidity. This robust construction minimizes deflection under load, a critical factor for achieving precise cuts and superior surface finishes in milling, grinding, and turning centers. The bearing's design facilitates straightforward mounting and ensures a long, reliable service life even under continuous, high-speed operation.

Integrating the 234412-M-SP into machine tool spindles delivers tangible benefits in performance and productivity. Its superior axial stiffness and minimal runout directly translate to improved workpiece quality and reduced scrap rates. The bearing's ability to handle high speeds allows for faster machining cycles, increasing overall output. Furthermore, the inherent reliability and durability of its design reduce machine downtime and maintenance costs. For manufacturers seeking to push the boundaries of precision engineering, this bearing provides the foundational stability needed to achieve unparalleled accuracy and operational efficiency.
