Construction and Design

The 6304 ZZ MGK utilizes a single-row deep groove ball bearing design equipped with metal shields on both sides.

The design provides:

• increased radial load capacity
• support for moderate axial loads
• protection against dust and particles
• lubricant retention
• low rolling resistance
• reliable high-speed operation

The ZZ metal shields generate lower friction than contact rubber seals, making the bearing particularly suitable for high-speed industrial machinery.

Material Properties

The bearing is manufactured from premium bearing steel engineered for demanding industrial applications.

Key properties include:

• excellent wear resistance
• high mechanical strength
• resistance to dynamic loads
• dimensional stability
• fatigue resistance
• precision raceway finishing
• long operational life
• industrial reliability
