A Comprehensive Guide to 2.5od x Contact Bearings: Everything You Need to Know

Introduction

2.5od x contact bearings are a versatile type of bearing used in numerous industrial and automotive applications. Their compact size, high load capacity, and precision make them an ideal choice for various demanding environments. This guide delves into the intricacies of 2.5od x contact bearings, providing a comprehensive understanding of their design, advantages, and applications.

Understanding 2.5od x Contact Bearings

What are 2.5od x Contact Bearings?

2.5od x contact bearings are miniature bearings with an outer diameter of 2.5 inches (63.5 mm) and a contact angle of 45 degrees. They feature a single row of rolling elements, typically ball bearings, which are held in place by a retainer. The contact angle allows the bearing to withstand both radial and axial loads.

Bearing Design

The design of 2.5od x contact bearings prioritizes durability and efficiency. The bearings are constructed from high-grade materials, such as chrome steel or stainless steel, ensuring resistance to wear and corrosion. The races and rolling elements are precisely ground to minimize friction and maximize bearing life.
