6301-2RSH/C3 Single Row Deep Groove Ball Bearing 12×37×12mm Double RSH Seal C3 Clearance Small Motor Pump

The 6301-2RSH/C3 is single row deep groove ball bearing equipped with double low-friction RSH reinforced NBR contact rubber seals and C3 enlarged radial clearance. The RSH lip seals tightly fit the raceway surface to block dust, water mist and liquid splashes, perfectly suited for damp, dusty and polluted working environments. C3 extra internal clearance reserves expansion space to eliminate thermal expansion jamming during continuous high-speed and high-temperature operation. It supports combined radial loads and light bidirectional axial loads, widely applied for small industrial motors, miniature water pumps, cooling fans, power tools and light mechanical transmission parts.

Complete technical data and dimensional drawings are available upon customer request.

1. Double RSH low-friction reinforced NBR seals balance outstanding sealing performance and low running torque, effectively isolate moisture, dust and impurities
2. C3 enlarged radial clearance offsets shaft thermal elongation, completely avoid bearing seizure under long-time high-temperature continuous operation
3. Standard deep groove raceway design ensures low vibration, low noise and stable high-speed rotation, bears radial and slight bidirectional axial loads simultaneously
4. Integrated pre-greased sealed structure retains internal lubricant, greatly extending maintenance interval without frequent refueling
5. Compact small-size structure saves installation space for miniature motors, power tools and small pump equipment
6. Customizable options include CN standard clearance, ZZ metal dust shield, OEM laser marking and special high/low temperature lubricating grease
