Product catalog summary
Introduction
Koyo Spherical Roller Bearings are engineered for self-alignment and high load capacity, suitable for low to medium speed applications with heavy or impact loading. They come with cylindrical or tapered bores and can include adapter assemblies and withdrawal sleeves, making them ideal for industrial applications with heavy loads and moderate speeds.

Product Line Up
The range includes double-row, combination radial and thrust bearings, designed for challenging environments. The JHS series offers high load ratings, allowing for downsizing and enhanced performance.

Types and Structures
Available in R, RH, RHR, and RHA types, these bearings differ in internal design and can have cylindrical or tapered bores with specific taper ratios.

Applications and Features
- R Type: Suitable for mechanical fans, blowers, pumps, and compressors, offering excellent load capacity and high-speed performance.
- RH, RHR Type: Used in heavy industrial conveyor systems and gearboxes, providing high load capacity and speed.
- RHA Type: Ideal for mining, construction equipment, and material handling machines, with excellent load capacity and speed.

Lubrication
Outer rings feature lubrication holes and grooves, marked by 'W33'.

Product Table
A detailed table lists boundary dimensions, load ratings, speeds, and bearing numbers. Special clearances are available, and the JHS range is recommended for large bearings.
Specifications and Data
The document details bearing specifications, including dimensions, load capacities, and model numbers, organized in a table highlighting dynamic and static load ratings, speed limits, and weight.
