The 6303ZZ Deep Groove Ball Bearing (17x47x14 mm) is a double-shielded, miniature bearing designed for high-speed applications requiring contamination protection. Featuring a single-row deep groove raceway, it accommodates radial and moderate axial loads in both directions. Constructed from chromium steel (GCr15) for durability, it includes stamped steel shields (ZZ) on both sides to retain lubricant and block debris.

Features

Double Metal Shields (ZZ)

The 6303 ZZ ball bearing features double metal contact shields that provide effective protection against dust, dirt, and other contaminants while retaining lubricant. This makes it ideal for applications where sealing is required but full-contact seals would reduce speed capability.

Precision Manufacturing

Manufactured to ABEC 1/P0 tolerance standards, ensuring consistent dimensional accuracy and smooth rotational performance. The precision-ground balls and raceways minimize vibration and noise.

High-Speed Performance

Despite the shields, the 6303 ZZ ball bearing maintains excellent speed capability with grease limiting speeds up to 13,000 rpm, making it suitable for small motors and high-speed applications.

Compact Design

With dimensions of 17x47x14mm, this miniature ball bearing is perfect for space-constrained applications while still delivering substantial load capacity.

Reliable Load Capacity

Deep groove raceway design provides excellent radial load capacity (13.5 kN dynamic rating) and can accommodate moderate axial loads in both directions.

We provide the following services:

OEM service, customized 6303 ball bearing size, logo and packaging;

CE certificate, EPR certificate and SGS report;
