Koyo KOYO6200-2RDC3 Deep Groove Ball Bearing C3

Product Description

The KOYO KOYO6200-2RDC3 is a deep groove ball bearing designed for rotating shaft applications in HVAC equipment, pumps, motors, and light industrial machinery. It features a 10 mm bore, 30 mm outer diameter, and 9 mm width. The bearing ships with light contact rubber seals on both sides, which retain grease and exclude contaminants while producing lower drag torque than standard contact seals. The C3 internal clearance designation indicates a looser-than-normal fit between the rolling elements and raceways, making this bearing well suited for applications where thermal expansion or press-fit mounting would otherwise preload a standard C0 bearing.

This bearing sees wide use in single-phase and three-phase motors, blower assemblies, circulator pumps, and fan shaft assemblies common to residential and light commercial HVAC systems. The C3 clearance and dual-seal configuration make it a preferred choice when the operating environment involves elevated temperatures or contamination risk. Technicians replacing failed motor or shaft bearings will find this a direct dimensional match to the 6200-series envelope wherever that series is called out.

Key Features

• Light contact rubber seals on both sides reduce drag torque while maintaining grease retention
• C3 internal clearance accommodates thermal expansion and press-fit shaft installations
• 10 mm bore fits common motor and pump shaft sizes in HVAC and light industrial applications
• Deep groove design handles both radial and modest axial loads
• Compact 9 mm width suits space-constrained motor housings and shaft assemblies

Compatibility

Designed as an OEM-style replacement for equipment specifying a 6200-series deep groove ball bearing with dual seals and C3 internal clearance.

Installation Notes

Bearing replacement should be performed by a qualified technician. Always disconnect and lock out power to the motor or unit before disassembly. Use a proper bearing press or driver tool sized to the inner or outer race to avoid brinelling the raceways during installation. Do not apply installation force through the rolling elements, and confirm shaft and housing diameters are within tolerance before pressing the new bearing into place.
