The SKF 6306-2ZJEM is a high-performance deep groove ball bearing engineered for demanding industrial and HVACR applications. Featuring a 30mm inside diameter, 72mm outside diameter, and a 19mm width, this radial ball bearing is optimized for high-speed operation with minimal friction. The C3 internal clearance provides the necessary radial room for thermal expansion, making it a critical choice for heavy-duty electric motors and fan assemblies where heat generation is a factor.

Built with high-grade bearing steel and a robust steel cage, this unit utilizes double shielded closure (2Z) to retain factory-applied grease while protecting the raceways from large contaminants without the drag of contact seals. As an SKF Explorer class component, it is designed for increased dynamic load capacity (29.6 kN) and reduced vibration, ensuring stable rotation up to a limiting speed of 11,000 RPM. This non-cancelable industrial-grade part is a standard requirement for contractors maintaining centrifugal pumps and air handling units.

• Electric Motor Quality (EMQ): Optimized for silent operation and reduced electromagnetic interference in motor housing.
• Thermal Management: C3 clearance ensures operational reliability in high-temperature environments by preventing internal binding.
• Maintenance-Free Design: Pre-lubricated and double shielded to prevent grease leakage in horizontal or vertical orientations.
• High Load Rating: Engineered to manage significant radial and moderate axial loads in both directions.

• What is the difference between 2Z and 2RS for the 6306 series? The 2Z suffix denotes non-contact steel shields, which allow for higher operating speeds compared to the 2RS contact rubber seals, which offer better moisture protection but more friction.
• Is this bearing suitable for high-speed HVAC fans? Yes, the SKF 6306-2ZJEM is rated for high rotational speeds with a reference speed of 20,000 RPM, making it ideal for belt-driven and direct-drive blowers.
• What does the JEM suffix indicate? In SKF nomenclature, JEM indicates a pressed steel cage and C3 internal clearance, standard for electric motor applications.
