260 Bearing Dimensions: A Comprehensive Guide

Introduction

Ball bearings are a critical component in various mechanical systems, providing support and reducing friction between moving parts. Among the various types of ball bearings, the 260 series stands out with its versatility and wide range of applications. This article delves into the dimensions, specifications, and applications of 260 bearings, providing valuable insights for engineers, manufacturers, and users alike.

Dimensions of 260 Bearings

260 bearings are characterized by their specific dimensions, which are standardized according to industry norms. The primary dimensions include:

1. Bore Diameter (d): The inner diameter of the bearing, which fits onto a shaft. Bore diameters for 260 bearings typically range from 10 mm to 150 mm.

2. Outer Diameter (D): The outer diameter of the bearing, which fits inside a housing. Outer diameters for 260 bearings range from 30 mm to 230 mm.

3. Width (B): The height or thickness of the bearing. Widths for 260 bearings vary depending on the specific size and type of bearing.

Types of 260 Bearings

Within the 260 series, there are various types of bearings available, each designed for specific applications:

1. Single-Row Radial Ball Bearings: The most common type, designed to support radial loads only.

2. Double-Row Radial Ball Bearings: Feature two rows of balls, providing increased radial load capacity.

3. Angular Contact Ball Bearings: Designed to support combined radial and axial loads. Available in single-row and double-row configurations.

4. Tapered Roller Bearings: Suitable for heavy radial and axial loads, commonly used in automotive applications.
