Flange bearings are indispensable components in various industrial machinery and equipment. Their robust design and versatility make them suitable for a wide range of applications, including agricultural machinery, construction equipment, and conveyor systems. This comprehensive guide delves into the world of flange bearings, empowering you with the knowledge to optimize their selection, installation, and maintenance.
A flange bearing is a type of rolling-element bearing that incorporates a flange on its outer ring. This flange provides additional mounting stability and ease of installation, allowing the bearing to be secured directly to a housing or other supporting structure. Flange bearings typically consist of a cylindrical inner ring that houses the rolling elements (balls or rollers) and an outer ring that houses the raceway for the rolling elements. The flange is attached to the outer ring, extending radially outward, providing the bearing with its distinctive appearance.
Flange bearings come in various types, each designed to meet specific application requirements:
