Rollway Bearings 6306 Bearing

The Rollway 6306EMQ is a precision-engineered 30mm ID open ball bearing designed specifically to provide high-performance cooling and lubrication for critical HVACR and electric motor applications. As a direct replacement for standard 6306 radial ball bearings, this EMQ (Electric Motor Quality) rated component features G10 ultra-precision balls and high-carbon SAE 52100 chrome steel construction, ensuring reduced vibration and lower noise levels in residential and commercial air handling units. With a 30mm bore, 72mm outside diameter, and 19mm width, this single-row deep groove bearing is optimized for high-speed operation, supporting dynamic load ratings up to 28.2 kN and reaching limiting speeds of 11,000 RPM in oil environments.

For technicians servicing fans, pumps, or blower motors, the 6306-EMQ offers superior radial load capacity compared to standard industrial-grade bearings. The open closure design allows for continuous re-lubrication in oil-mist or bath systems, maintaining low friction and optimal heat dissipation in demanding duty cycles. Whether performing a routine motor swap or a system overhaul, utilizing 6306 metric ball bearings with EMQ specifications is essential for minimizing parasitic noise and extending the service life of high-RPM rotating equipment.

• EMQ Rated Performance: Specifically manufactured to the Electric Motor Quality standard for ultra-low noise and minimal vibration in HVAC motors.
• High Load Capacity: Robust 28.2 kN dynamic and 15.8 kN static load ratings ensure stability under severe belt tension or mechanical stress.
• Precision Tolerance: Features ABEC 3 precision standards and G10 balls for tighter internal clearances and smoother rotation.
• Direct Interchange: Fully compatible as a direct replacement for 6306 standard open bearings across all major 6300 series applications.

• What is the difference between a standard 6306 and the 6306EMQ? The EMQ designation signifies higher manufacturing precision and finishing on the raceways, resulting in quieter operation required for electric motors compared to standard industrial variants.
• Can this bearing be used in vertical shaft applications? Yes, the deep groove design allows it to handle both significant radial loads and moderate axial (thrust) loads in both directions.
• Does this bearing come pre-greased? As an open-type bearing, it is supplied with a light rust-inhibitive oil and requires the application of compatible lubrication (grease or oil) during installation based on your specific system requirements.
