Koyo KOYO6214-2RDC3 Deep Groove Ball Bearing C3 Clearance

Product Description

The KOYO KOYO6214-2RDC3 is a deep groove ball bearing built for rotating equipment found in HVAC, pump, motor, and fan drive applications. It features a 70 mm bore, 125 mm outer diameter, and 24 mm width, placing it in the 6214 frame size. The double-sealed design uses light contact seals on both sides to retain grease and exclude contaminants while keeping rotational resistance low. The C3 internal clearance designation means the bearing is spec'd for applications where thermal expansion or press-fit mounting demands more internal play than standard clearance bearings provide. Licensed HVAC technicians, pump mechanics, and motor repair shops are the typical installers.

This bearing is suited for residential and commercial HVAC blower motors, condenser fan motors, pump shafts, and general-purpose rotating machinery where a sealed, low-torque bearing is required. The C3 clearance makes it appropriate for applications with elevated operating temperatures or interference fits on the shaft or housing. It is a direct replacement bearing in any application calling for the 6214 2RDC3 specification.

Key Features

• 70 mm bore, 125 mm outer diameter, 24 mm width — standard 6214 frame dimensions
• Double-sided light contact seals reduce torque drag while protecting internal raceways
• C3 internal clearance for elevated-temperature or interference-fit installations
• Deep groove raceway design handles radial loads and moderate axial loads in both directions
• Factory-greased and sealed, requiring no field lubrication at installation

Compatibility

Designed as a direct replacement for any application specifying a 6214 2RDC3 deep groove ball bearing with a 70 mm bore, 125 mm outer diameter, and 24 mm width with C3 clearance and light contact seals.

Installation Notes

Bearing replacement should be performed by a qualified mechanic or technician. De-energize and lock out all power to the equipment before disassembly. Use a bearing press or proper pull-and-drive tooling to seat the bearing squarely against the shaft shoulder and housing bore — never strike the bearing directly with a hammer. Verify shaft and housing dimensions fall within tolerance before installing to avoid damaging the new bearing.
