Understanding the 35x72x18 mm Bearing Features, Applications, and Importance
Bearings are crucial components in the machinery and equipment industry, enabling smooth movement and reducing friction between moving parts. One commonly referenced bearing size in various applications is the 35x72x18 mm bearing. In this article, we will explore the features, applications, and significance of this bearing size, along with a look into its construction and maintenance.
What is a 35x72x18 mm Bearing?
The numbers in the designation 35x72x18 mm indicate the bearing's dimensions a bore diameter of 35 mm, an outside diameter of 72 mm, and a width of 18 mm. These bearings are typically manufactured as deep groove ball bearings, which can accommodate radial and axial loads in both directions.
Construction and Design
Deep groove ball bearings, including the 35x72x18 mm size, consist of several key components
1. Inner Race The inner circular track that fits onto the shaft. 2. Outer Race The outer circular track that fits into the housing. 3. Balls These are positioned between the inner and outer races, allowing for smooth rotation. 4. Cage A separator that holds the balls in place, preventing them from contacting each other and allowing optimal performance.
The design of deep groove ball bearings facilitates high-speed operation while supporting both radial and axial loads, making them versatile for various uses.
