Key Performance Advantages:
P4 Super-Precision Accuracy: Manufactured to P4 precision standards, this bearing ensures minimal runout and exceptional rotational accuracy, which is vital for high-end CNC machining and spindle assemblies.
Superior Radial Rigidity: The double-row design provides a larger contact surface compared to single-row bearings. Combined with the C1 internal clearance, it offers maximum stiffness and stability under heavy radial cutting loads.
Machined Brass Cage (KM): The heavy-duty brass cage provides excellent durability and heat dissipation. Being guided by the rolling elements, it reduces friction and vibration, allowing for stable performance at high operational speeds.
Tapered Bore (1:12): The tapered bore allows for extremely precise adjustment of the radial internal clearance during mounting, ensuring the bearing can be perfectly tuned for the specific spindle requirements.
High Speed Performance: The optimized internal geometry and high-grade materials allow the NN 3015 RICH to operate at high RPMs without excessive heat buildup, extending the life of both the bearing and the spindle.
Transparency Note: This product is manufactured under the RICH brand. The code NN 3015 KMP41 is used for identification purposes.
