2.5OD x Contact Bearing: A Comprehensive Guide to Precision Performance

In the realm of precision engineering, bearings play a crucial role in ensuring smooth operation and minimizing friction. Among the various types of bearings, the 2.5OD x contact bearing stands out for its compact size, high load capacity, and exceptional precision. This article delves into the world of 2.5OD x contact bearings, providing an in-depth understanding of their design, applications, and benefits.

Understanding 2.5OD x Contact Bearings

2.5OD x contact bearings are small, self-contained units consisting of an outer race, an inner race, and precision-ground ball elements. The precise manufacturing process ensures minimal tolerances, resulting in smooth operation and extended service life.

Design and Construction

• Outer Race: The outer race is typically made of hardened steel and features a precision-ground raceway with a slight curvature to accommodate the ball elements.
• Inner Race: The inner race is also made of hardened steel and has a slightly smaller diameter than the outer race. It rotates with the shaft and features a raceway that conforms to the ball elements.
• Ball Elements: The precision-ground ball elements are made of high-quality steel and are carefully selected for their size and shape to optimize load distribution and minimize friction.
