1300 Series

The 1300 Series Self-Aligning Ball Bearings are double-row precision bearings composed of two rows of balls, a cage, a solid inner ring, and an outer ring with a common concave spherical raceway. Engineered for exceptional self-aligning performance, these bearings effectively compensate for angular misalignments of the shaft relative to the housing, as well as shaft deflection and housing deformation, making them ideal for applications where precise alignment is challenging. With low friction, reliable load capacity, and flexible configurations, they are widely used in various light to medium-duty industrial, automotive, and consumer equipment scenarios requiring smooth, stable operation.

PRODUCT DETAILS

🎯 Self-Aligning Performance & Stability

The 1300 series features a single-row spherical outer ring that automatically compensates for angular misalignment and mounting errors. This self-aligning design ensures stable running, reduces vibration, and significantly extends service life by minimizing wear.

⚙️ Premium Material & Load Capacity

Crafted from high-grade GCr15 bearing steel, these bearings excel in handling radial loads with minimal axial resistance. Available in open or sealed (2RS/ZZ) types, they deliver robust durability, low friction, and quiet operation under continuous industrial conditions.

🛠️ Versatile Industrial Applications

Commonly used in small gearboxes, motors, fans, pumps, and textile machinery, the 1300 series is the standard solution for light to medium-duty power transmission. Their precision machining ensures easy installation and reliable performance across diverse manufacturing environments.

Category Overview

Self-aligning Ball Bearings are double-row radial ball bearings with a spherical outer raceway, designed with strong self-aligning performance. They can effectively compensate for shaft deflection and installation misalignment, while bearing radial loads and slight axial loads.With low friction, quiet running and easy installation, they are widely used in light to medium‑duty equipment where shaft misalignment is common.
