NSK Open Deep Groove Ball Bearings are high-performance, precision-engineered components designed for smooth, high-speed rotation with minimal friction, making them ideal for a wide range of industrial, automotive, and mechanical applications. Manufactured by NSK Ltd., these open-type bearings allow for easy lubrication and maintenance, ensuring optimal performance in controlled environments where contamination is minimal. Known for their durability, low noise operation and high load capacity, NSK open deep groove ball bearings are widely used in electric motors, pumps, gearboxes, and machinery requiring reliable and efficient motion. Their simple yet robust design supports both radial and axial loads, providing versatility across various industries.
The NSK 6212-C3 is a high-quality single-row deep groove ball bearing with a 60mm bore, 110mm outside diameter, and 22mm width, engineered for applications requiring reliable performance and the ability to handle thermal expansion. As an open-type bearing, its design allows for easy relubrication and is ideal for high-speed operation, while the C3 radial internal clearance provides a greater-than-normal internal gap to accommodate thermal expansion, preventing unwanted preload and ensuring consistent performance under fluctuating temperatures or at high speeds. Manufactured to NSK's exacting standards, this bearing delivers a dynamic load rating of 57.5 kN and a static load rating of 36.0 kN, supporting both radial and axial loads in either direction with minimal friction, and with a grease lubrication limiting speed of 6,700 rpm and oil lubrication capability of 8,000 rpm, it is well-suited for electric motors, pumps, compressors, gearboxes, and general industrial machinery. Featuring a pressed steel cage and ten precision-ground 15.875mm balls, the NSK 6212-C3 delivers consistent, low-vibration, and quiet operation, making it an ideal choice for demanding industrial environments where thermal variation and high-speed performance are key considerations.
