Rollway Bearings 6208ZZC3EMQ Bearing

The Rollway Bearings 6208ZZC3EMQ is a high-performance deep groove ball bearing engineered for heavy-duty industrial and HVAC motor applications. This 40mm ID double shielded ball bearing features a 40mm bore, 80mm outer diameter, and 18mm width, providing a precision fit for high-speed shafts. As the direct replacement for the 6208-ZZ-C3, it is manufactured with 52100 bearing steel to handle significant radial loads while maintaining low frictional torque. The C3 radial internal clearance is specifically designed to accommodate thermal expansion in high-temperature environments, preventing premature seize-up. This Electric Motor Quality (EMQ) rated component ensures quiet operation and minimal vibration, critical for condenser fan motors and air handlers. The dual metal shields offer superior protection against dust and debris without increasing rotational drag. For contractors and technicians, this radial ball bearing provides the reliability needed for demanding service calls.

• Electric Motor Quality: Engineered with EMQ specifications for near-silent operation and reduced vibration in HVAC units.
• Enhanced Thermal Tolerance: C3 internal clearance allows for optimal performance during heat-induced shaft expansion.
• Dual-Shield Protection: Metal shields on both sides retain lubricant while blocking contaminants in harsh mechanical rooms.
• Drop-In Compatibility: Serves as a standard 6208zz replacement, ensuring quick field swaps without housing modifications.

• Can I use this shielded bearing in place of a sealed 6208-2RS? Yes, the 6208ZZC3EMQ has identical dimensions (40x80x18mm). While shields offer lower drag for high-speed motors, ensure your environment does not require the moisture-tight properties of a rubber seal.
• Why is the C3 clearance important for HVAC motors? HVAC motors generate significant heat; a C3 clearance provides the necessary room for internal components to expand without causing metal-on-metal binding.
• What does the EMQ rating signify for my application? Electric Motor Quality means the bearing has undergone specialized testing for noise and vibration, making it the industry standard for high-efficiency air conditioning and heating equipment.
