Chapter 1: Understanding the Anatomy of a 2.5OD x Contact Bearing

1.1: What is a 2.5OD x Contact Bearing?

A 2.5OD x contact bearing, as the name suggests, is a type of ball bearing with an outer diameter (OD) of 2.5 inches and a contact angle of 0 degrees. This particular design features a single row of balls that make direct contact with the inner and outer races, enabling it to withstand both radial and axial loads.

1.2: Key Components and Specifications

• Inner Race: The innermost component that rotates along with the shaft.
• Outer Race: The stationary component that supports the inner race and balls.
• Balls: Precision-ground spheres that roll between the inner and outer races.
• Cage: A retainer that keeps the balls evenly spaced and prevents them from slipping.

Additional Specifications:

• Material: Typically constructed from high-quality steel or ceramic for durability and corrosion resistance.
• Accuracy: Graded on a scale of ABEC-1 to ABEC-9, with higher numbers indicating greater precision.
• Load Capacity: Rated for both radial and axial loads, expressed in pounds or newtons.
