The Nachi 6307-2NSENR is a high-performance deep groove ball bearing designed for demanding electrical and mechanical applications, featuring a 35mm inner diameter, 80mm outer diameter, and 21mm width for precise fit and reliable operation. This double-sealed bearing utilizes Buna-N rubber contact seals on both sides to effectively prevent contamination and grease leakage, while the C3 radial clearance ensures optimal performance under varying thermal conditions. With a dynamic load capacity of 33,500 N and a static load capacity of 19,200 N, it supports high rotational speeds up to 6,000 rpm with grease lubrication. The stamped steel cage enhances durability, and the integrated snap ring groove allows for secure axial positioning, making it ideal for electric motors, automotive alternators, compressors, and other applications requiring smooth, quiet, and maintenance-free operation. Its robust construction, combined with NACHI’s original seal design and special grease, ensures extended service life and consistent performance across a wide temperature range up to 250°F.
