5200-ZZ Double Row Angular Contact Bearing 10mm ID x 30mm OD Shield

Description

Product Overview

The 5200-ZZ double row angular contact ball bearing is engineered to meet the rigorous demands of modern industrial applications. Constructed by QJZ, a reputable manufacturer known for precision engineering, this bearing features a double row configuration that enhances load capacity and stability. The angular contact design allows the bearing to accommodate both radial and axial loads, making it versatile for a variety of mechanical systems. With an inner diameter of 10 mm, an outer diameter of 30 mm, and a width of 14.3 mm, the bearing offers a compact footprint while delivering high performance. The double metal shield (ZZ) provides superior protection against dust, debris, and moisture, extending the service life and reducing maintenance intervals. Made from high‑quality steel, the bearing is heat‑treated for increased hardness and wear resistance, ensuring reliable operation even under extreme temperature fluctuations. This product is a perfect fit for applications ranging from automotive drivetrains to agricultural machinery, tractors, and construction equipment, where durability and precision are paramount.

Usage

Designed for versatility, the 5200-ZZ bearing excels in environments where both radial and axial forces are present. In automotive settings, it can be employed in transmission assemblies, differential housings, and wheel hub units, providing smooth rotation and reducing vibration. Agricultural and tractor applications benefit from its ability to handle heavy loads while resisting contamination from soil, dust, and moisture, making it ideal for power take‑off (PTO) shafts, gearboxes, and hydraulic pump drives. Construction machinery, such as excavators, loaders, and compactors, rely on the bearing’s robust shielding to maintain performance in harsh, dusty job sites. The bearing’s compact dimensions allow it to be integrated into tight spaces without sacrificing strength, and its double metal shield eliminates the need for additional sealing components, simplifying installation and maintenance. Whether the equipment operates continuously in a factory, intermittently on a farm, or under the rigors of a construction site, the 5200-ZZ bearing delivers consistent performance and longevity.

FAQ

What does the “ZZ” designation mean?

“ZZ” indicates that the bearing is equipped with a double metal shield on both sides. This shielding prevents external contaminants such as dust, dirt, and moisture from entering the bearing while still allowing lubrication to circulate, which helps maintain performance and prolongs the bearing’s life.

Can this bearing be used in high‑temperature environments?

Yes. The bearing is made from high‑quality steel that has been heat‑treated to achieve a high hardness level, allowing it to operate reliably in temperatures up to 120 °C (248 °F) when properly lubricated. For applications exceeding this range, a specialized high‑temperature lubricant should be used.

How do I determine the correct lubrication type for this bearing?

For most industrial and automotive applications, a high‑quality mineral oil or synthetic grease with a viscosity suitable for the operating temperature range is recommended. The double metal shield helps retain the lubricant, but regular inspection and re‑lubrication according to the manufacturer’s schedule will ensure optimal performance.

Is the bearing compatible with standard shafts and housings?

The 5200-ZZ bearing has a 10 mm inner diameter and a 30 mm outer diameter, which conforms to common metric shaft and housing dimensions. It can be installed in any equipment that matches these specifications, provided that proper fit tolerances and mounting procedures are followed.

What warranty does QJZ offer for this bearing?

QJZ provides a limited one‑year warranty covering manufacturing defects and material failures under normal operating conditions. The warranty includes replacement of defective units and technical assistance to resolve any performance issues that arise during the warranty period.
