Product Description

SKF 6304/C4 Single Row Deep Groove Ball Bearing offers a robust solution for various industrial rotary applications requiring high-speed capability and precise internal clearance.

This ball bearing features a 20 mm inside diameter (ID) and 52 mm outside diameter (OD), designed specifically as a single row deep groove bearing that can support radial loads while accommodating limited axial load conditions.

The bearing incorporates a C4 internal clearance classification, allowing for thermal expansion during operation and minimizing the risk of seizure or undue preload caused by temperature variations. Its sheet metal cage construction significantly reduces centrifugal mass, promoting operational stability during high RPM.

Steel races and balls ensure durability and wear resistance under sustained load, making this bearing suitable for extended operational cycles in industrial environments. The open end design eases maintenance tasks including lubrication and inspection.

Applications include high-speed spindles, precision motor shafts with cylindrical bore mounts, conveyor rollers experiencing moderate radial forces, and gearbox idler shafts that require defined internal clearance for smooth functionality.

Made in Italy, this SKF bearing adheres to quality standards ensuring long service life and operational reliability in demanding industrial, manufacturing, and mechanical power transmission contexts.

Designed for single row deep groove ball bearing applications supporting radial and axial loads. C4 internal clearance enhances thermal tolerance and load accommodation. Steel races and bearing balls provide high durability and resistance to wear.

Sheet metal cage design minimizes mass for better performance at high speeds. Open end type facilitates maintenance access for lubrication and inspection. Ideal for precision motor shafts, conveyor rollers, and gearbox idler shafts.

Supports limiting speed up to 19000 rpm for demanding rotational environments. Manufactured in Italy ensuring consistent quality and reliability.
