SKF E2.608 ZZ C3 Deep Groove Ball Bearing 8x22x7

Overview

The SKF E2.608 ZZ C3 is an energy-efficient single row deep groove ball bearing developed as part of the SKF Energy Efficient (E2) product range. Compared with conventional deep groove ball bearings, the E2 design features optimized internal geometry, a specially formulated low-friction grease and double non-contact metal shields (2Z/ZZ) to reduce friction, lower operating temperature and improve service life. The C3 internal clearance makes the bearing suitable for high-speed applications with elevated operating temperatures.

Industrial Applications

The bearing is widely used in electric motors, industrial fans, pumps, HVAC equipment, conveyor systems, automation equipment, compact gearboxes, machine tools, power transmission systems and OEM machinery where energy efficiency, reduced heat generation and continuous high-speed operation are important.

Construction

The E2.608 ZZ C3 incorporates precision-ground raceways, hardened steel balls and a pressed steel cage. The double non-contact metal shields (2Z/ZZ) protect the lubricant from contamination without contacting the inner ring, minimizing friction and allowing higher operating speeds. The C3 clearance compensates for thermal expansion during continuous operation.

Material

The rings and rolling elements are manufactured from premium through-hardened SKF bearing steel with excellent fatigue strength and wear resistance. The bearing is factory lubricated with a specially developed low-friction grease used in the SKF Energy Efficient series, reducing running torque and extending operating life.

FAQ

What does the E2 designation mean?

E2 identifies the SKF Energy Efficient series, engineered to reduce friction, operating temperature and energy consumption.

What does ZZ (2Z) indicate?

It indicates double non-contact metal shields that protect the lubricant while maintaining low running resistance.

What is the purpose of C3 internal clearance?

C3 clearance compensates for thermal expansion during high-speed or elevated-temperature operation.

Is the bearing supplied pre-lubricated?

Yes. It is factory-filled with SKF low-friction grease and ready for installation.

Can the E2.608 ZZ C3 replace a standard 608 bearing?

Yes, provided the application benefits from C3 clearance and the operating conditions match the bearing specification.
