Rollway Bearings 6205ZZC3EMQ Bearing

The Rollway Bearings 6205ZZC3EMQ is a high-performance deep groove ball bearing specifically engineered for the rigorous demands of HVAC and electric motor applications. Featuring a 25mm inner diameter, 52mm outer diameter, and 15mm width, this single-row radial bearing is optimized for vertical and horizontal shaft support where low noise and vibration are critical. The Electric Motor Quality (EMQ) designation ensures high-precision manufacturing, making it the preferred choice for contractors servicing condenser fans and blower motors found in premium air handling units.

Equipped with dual metal shields (ZZ), this bearing provides essential defense against dust and debris while retaining high-grade factory lubrication, extending the service life of rotating assemblies. The C3 internal clearance is vital for high-speed operation, as it allows for thermal expansion during continuous duty cycles, preventing premature seized-bearing failures. Built from 52100 high-carbon chrome steel, the 6205ZZC3EMQ delivers a 14 kN dynamic load rating, ensuring reliable power transmission in high-torque environments.

Key Benefits:

• Electric Motor Quality (EMQ) Rating: Specifically designed for ultra-low noise and minimal vibration in hvac motor repair.
• Double Metal Shields: Protects internal raceways from contaminants and retains lubricant without increasing friction.
• C3 Clearance Specification: Accommodates thermal expansion in high-speed industrial motors, preventing shaft binding.
• Precision Radial Loading: Optimized for circular raceway stability under both high-radial and moderate-axial loads.
• Universal Compatibility: Standard 25x52x15mm dimensions for seamless replacement in major HVAC and pump brands.

Common Questions:

What is the maximum RPM for the Rollway 6205ZZC3EMQ?
This bearing is grease-lubricated and rated for speeds up to 13,000 RPM, making it ideal for standard 2-pole and 4-pole electric motors.

Can I use a C3 clearance bearing where a standard clearance is specified?
Yes, C3 clearance is preferred for motors that experience high heat or operational friction, as the extra internal space prevents failure when components expand.

Why choose EMQ over a standard industrial bearing?
EMQ bearings undergo tighter quality control to ensure quieter operation, which is critical for HVAC installations in residential or office environments where noise suppression is a priority.
