Prevent Costly Downtime with Precision Double Row Cylindrical Roller Bearing NN3013-K-TN-SP
Equipment failures due to substandard bearings cost manufacturers thousands in lost production daily. Many buyers struggle with mismatched tolerances causing premature wear, or delayed shipments when sourcing critical replacement parts. For precision mechanical equipment, even minor bearing inaccuracies can lead to vibration issues, increased energy consumption, and unplanned maintenance stops.
Genuine Double Row Cylindrical Roller Bearings, In Stock and Ready for Shipment
Our NN3013-K-TN-SP Double Row Cylindrical Roller Bearing eliminates these frustrations by combining European precision standards with reliable availability. As an official distributor, we maintain centralized inventory across 55+ countries, ensuring this critical component is ready for immediate dispatch. Whether for CNC machine spindles requiring tight tolerance control or industrial gearboxes handling heavy radial loads, this bearing delivers consistent performance where precision matters most.
Engineered for High-Precision Mechanical Applications
This Double Row Cylindrical Roller Bearing excels in applications demanding high radial load capacity and precise axial alignment. Its separated design allows for easy mounting and dismounting, making it ideal for equipment where maintenance accessibility is crucial. The bearing operates efficiently in moderate speed environments typical of machine tools, steel processing lines, and wind power gearboxes, where stable performance under continuous operation directly impacts production efficiency.
Technical Features That Ensure Reliable Performance
The NN3013-K-TN-SP features a brass or steel cage that provides robust guidance for rollers, reducing friction and ensuring even load distribution. With clearance options from C0 to C5, it can be precisely matched to specific operating conditions—tighter clearances (C2) for high-precision spindles, or larger clearances (C4-C5) for applications with thermal expansion. Vibration levels rated Z1V1 to Z3V3 ensure smooth operation, critical for minimizing noise in precision machinery. The bearing steel construction, hardened to 60-64 HRC, delivers the durability needed to withstand the rigors of industrial environments.
Why Authentic Bearings Deliver Lower Total Cost of Ownership
Counterfeit bearings often fail within 30-50% of the expected service life of genuine components, leading to repeated replacement cycles and unplanned downtime. A single hour of production loss in manufacturing can exceed the cost of five genuine bearings. Our products adhere to ISO 9001 quality standards, with each unit inspected before shipment to ensure compliance with original specifications. This commitment to quality reduces long-term costs by extending maintenance intervals and preventing collateral damage to connected equipment.
