NSK Single Row Deep Groove Ball Bearing 20 mm ID 52 mm OD 15 mm Width Shielded Steel Cage 16000 rpm 6304ZZ

NSK 6304ZZ is a single row deep groove ball bearing designed with a 20 mm inside diameter, 52 mm outside diameter, and 15 mm race width. Featuring a steel cage and steel balls, this shielded (ZZ) bearing is engineered to prevent contamination with metal dust shields on both sides, enhancing service life and reliability.

These bearings accept both radial and axial loads and operate efficiently at speeds up to 16,000 rpm, making them ideal for high-speed industrial machinery. NSK bearings are widely used across diverse sectors including printing, medical equipment, manufacturing plants, agricultural machinery, and renewable energy devices such as wind turbines.

The parallel bore design ensures precise mounting and stability in assembly. The bearing complies with NSK’s medium series 3 standards and utilizes a plain race type for smooth, dependable rotation. Internal clearance is CN, supporting consistent performance under dynamic loads.

Its shielded end type (6304ZZ) provides robust protection from dust and debris, which is crucial in environments exposed to contaminants. The steel cage construction enhances durability and maintains ball retention during operation.

The dynamic load rating of 15.9 kN combined with a static load rating of 7.9 kN supports varied load conditions effectively, contributing to long operational life and minimized maintenance.

Equipped with steel cage and steel balls for durability and reliable operation. Shielded design (ZZ) protects against dirt and foreign matter ingress. Accepts both radial and axial loads efficiently. Supports limiting speeds up to 16,000 rpm for high-speed performance.

Suitable for various industrial applications including printing, medical, manufacturing, and agricultural machinery. Single row construction enables compact design and robust load handling. Parallel bore type ensures secure fitting in housings.

Compliant with NSK's medium series 3 specifications for optimal performance.

This NSK 6304ZZ ball bearing is an essential component for rotary machinery requiring compact, high-performance bearings with effective shielding. It offers reliability and long service intervals in demanding industrial environments.
