Exceptional Radial Rigidity: The double row configuration provides a significantly larger number of rolling elements than a single row bearing, ensuring maximum stiffness and stability under heavy radial loads.
W33 Lubrication System: The outer ring is equipped with a circumferential groove and three lubrication holes (W33). This allows for direct and efficient relubrication of the raceways, reducing friction and extending the bearing's service life.
Durable Machined Brass Cage: The brass cage is designed for high-stress environments. Guided by the rolling elements, it offers superior sliding properties and durability, even at high rotational speeds.
High Precision Stability: Designed for high-speed operation, the NN 3012 RICH maintains tight dimensional tolerances, preventing vibration and ensuring smooth performance in precision engineering applications.
Cylindrical Bore Design: The 60 mm cylindrical bore allows for easy mounting on standard cylindrical shafts, providing a secure and reliable fit for critical drivetrains.
Transparency Note: This product is manufactured under the RICH brand. The code NN 3012 MW33 is used for identification purposes.
