PBF 6009 ZZ C3 Deep Groove Ball Bearing 45x75x16

Overview

The PBF 6009 ZZ C3 is a single row deep groove ball bearing equipped with double non-contact metal shields (ZZ) and C3 internal clearance. Unlike the open 6009 version, this bearing is factory lubricated and permanently protected against dust and airborne contaminants, making it suitable for applications requiring extended maintenance intervals. The increased internal clearance compensates for thermal expansion during high-speed operation and elevated operating temperatures.

Industrial Applications

The bearing is widely used in electric motors, industrial gearboxes, pumps, compressors, fans, conveyor systems, agricultural machinery, material handling equipment, machine tools, HVAC systems and OEM power transmission equipment operating under continuous duty conditions.

Construction

The 6009 ZZ C3 features precision-ground deep raceways with a single row of hardened steel balls guided by a pressed steel cage. Double non-contact metal shields (ZZ) retain the factory grease while protecting the rolling elements against dust and contamination without creating sealing friction. The C3 internal clearance improves operating stability in applications subject to heat generation and high rotational speeds.

Material

The inner ring, outer ring and rolling elements are manufactured from premium through-hardened bearing steel, providing excellent fatigue strength, wear resistance and dimensional stability. The bearing is factory-filled with high-quality grease for long service life, while the steel shields reduce maintenance requirements by protecting the lubricant throughout normal operation.

FAQ

What does ZZ indicate?

ZZ designates double non-contact metal shields that retain lubricant while protecting the bearing against contamination.

What is the purpose of C3 internal clearance?

C3 clearance compensates for thermal expansion and supports reliable operation at higher temperatures and rotational speeds.

Is the bearing supplied pre-lubricated?

Yes. The bearing is factory greased and ready for installation.

Are the ZZ shields contact seals?

No. They are non-contact metal shields that minimize friction while protecting the bearing.

Can the PBF 6009 ZZ C3 replace an OEM bearing?

Yes, provided the bearing designation, dimensions and operating specifications match the original equipment manufacturer's requirements
