JSB Great Bearings 5201ZZ Row Angular Shield Bearing 12x32x15.9mm

Description

Product Overview

The 5201ZZ double row angular shield bearing from JSB Great Bearings is engineered to meet the rigorous demands of modern industrial machinery. With an inner diameter of 12 mm, an outer diameter of 32 mm, and a width of 15.9 mm, this bearing provides a compact footprint while delivering exceptional load-carrying capacity. Constructed from high‑grade chrome steel, the bearing offers excellent wear resistance and fatigue strength, ensuring long service life even under continuous high‑speed operation. Both sides of the bearing are protected by metal ZZ shields, which prevent contamination from dust, debris, and moisture while retaining lubrication for optimal performance. The double‑row angular contact design enhances rigidity and axial load handling, making it suitable for applications where precision and stability are critical. Detailed specifications include a 12 mm ID, 32 mm OD, 15.9 mm width, and a double row configuration that distributes loads evenly across the raceways, reducing stress concentrations and extending bearing lifespan.

Usage

This bearing excels in a variety of industrial environments, including high‑speed pumps, gearboxes, compressors, and motor assemblies. Its robust construction allows it to operate reliably in harsh conditions such as elevated temperatures, high vibration, and exposure to contaminants. Engineers and maintenance professionals often select the 5201ZZ bearing for applications that demand precise angular positioning, such as spindle drives, robotic arms, and precision tooling. The shielded design reduces the need for frequent lubrication checks, lowering maintenance costs and downtime. Whether installed in a manufacturing line, a processing plant, or a heavy‑duty equipment setup, the bearing provides consistent performance, ensuring smooth rotation and minimizing wear on adjoining components.
