Rollway Bearings 6207ZZC3EMQ Bearing

When you're pulling a motor for a 35mm shaft, you need a bearing like the Rollway 6207ZZC3EMQ that handles the heat and the load without breaking a sweat. This is a deep groove ball bearing with a 35mm bore, 72mm OD, and 17mm width, engineered specifically for high-performance HVAC motor replacement and industrial fan assemblies. The C3 radial internal clearance is a critical spec here; it provides that extra room for thermal expansion when your blowers or pumps are running at high RPMs, preventing premature seizing. The EMQ (Electric Motor Quality) rating ensures this unit operates with minimal vibration and low noise levels, which is exactly what you need in commercial air handling systems where acoustics matter. With its double shielded (ZZ) design, the 6207ZZC3EMQ retains its factory-fill lithium-base grease while blocking out the dust and debris common in mechanical rooms. Whether you're swapping parts in a centrifugal pump or an exhaust fan, this 35mm shielded ball bearing delivers a 25.7 kN dynamic load rating, making it a reliable workhorse for heavy-duty radial and axial loads.

• Thermal Stability: The C3 clearance allows for shaft expansion during continuous operations, maintaining optimal rotation.
• Contamination Protection: Dual metal shields (ZZ) provide a physical barrier against particulates while securing internal lubrication.
• Superior 52100 Steel: High-carbon chrome steel construction ensures high fatigue strength and resistance to wear under high radial ball bearing loads.
• Quiet Operation: The EMQ precision grinding reduces friction and harmonic resonance, extending the life of your motor housing.

Is the Rollway 6207ZZC3EMQ compatible with high-speed fan applications?
Yes, this bearing is rated for speeds up to 9,000 RPM with grease lubrication. Its deep groove geometry and EMQ rating make it ideal for high-speed HVAC blower wheels and motor drives.

Why choose C3 clearance over standard clearance for a 35mm bearing?
In HVACR applications, motors often generate significant heat. Standard clearance can become too tight as the components expand, leading to increased friction. The C3 clearance provides the necessary tolerance for these high-temperature environments.

Can this bearing be used in wet environments?
While the ZZ metal shields protect against dust and splashing, they are not hermetically sealed. For direct exposure to heavy moisture or wash-down conditions, we recommend reviewing our 2RS (rubber sealed) alternatives.
