NTN MU 1315 L Self-Aligning Ball Bearing - 75x160x37mm High Capacity Industrial Grade

The NTN MU 1315 L is a high-performance self-aligning ball bearing engineered specifically for industrial applications prone to shaft deflection or mounting errors. Featuring a 75mm bore, 160mm outer diameter, and 37mm width, this bearing utilizes two rows of balls operating in a spherical outer ring raceway, allowing it to accommodate significant angular misalignment without stressing internal components. The robust design, characterized by the 'MU' high-precision designation, ensures reliable operation and prolonged service life even under fluctuating loads and speeds. This inherent self-correcting capability drastically reduces the likelihood of premature failure caused by common installation inaccuracies. Designed for environments demanding maximum reliability, the NTN 1315 series is ideal for use in conveying systems, agricultural machinery, paper mills, and heavy-duty fans where maintenance access is difficult and downtime is costly. The 'L' suffix often denotes specific cage material or clearance optimization (typically C3 or standard CN), ensuring lower friction and heat generation at operational speeds up to 4,800 RPM (grease lubrication). Investing in NTN means securing component consistency, superior material quality, and reduced lifetime ownership costs due to exceptional durability and reduced need for frequent component replacements.

Key Features
