Applications
The 6312 series deep groove ball bearing is one of the most widely used bearing types in industrial and mechanical engineering. The double rubber seal (2NSE/2RS) construction keeps lubricant in and contaminants out, making it well suited for applications in moderately dirty or wet environments without requiring a separate external seal. The C3 clearance designation indicates a radial internal clearance greater than the standard CN class, which is specified when the bearing will operate at elevated temperatures, run with a tight interference fit on the shaft or housing, or be used in high-speed applications where thermal expansion during operation would otherwise tighten clearances to an unacceptable level. Typical uses for a bearing of this size and type include electric motors, pumps, compressors, fans, conveyors, agricultural machinery, gearboxes, and general industrial power transmission equipment. Nachi is a Japanese manufacturer with a long history of producing precision bearings to JIS and ISO standards, and 6312-2NSE bearings from Nachi are widely used as OEM and replacement bearings in both industrial and mobile equipment.
This Nachi 6312-2NSE Deep Groove Ball Bearing is new and unused, in its original Nachi-branded box. The bearing shows no signs of use, wear, or handling damage. The rubber seals are clean and intact, and the steel races appear free of rust or blemish. Please view our photo set and contact us if you have any questions.
