Product Description

This Lovejoy BWC-Series bellows coupling is a shaft coupling for joining two shafts in power transmission applications. It has a bellows design for up to .016" of axial misalignment and low reactionary loading on the bearings. It has aluminum hubs for resistance to corrosion and light weight and a stainless steel bellow for resistance to corrosion. It is a 1-piece coupling with clamping style hubs for easy installation and removal and a key way for secure attachment to the shafts. It has a maximum operating temperature of 212 degrees F and a maximum rotational speed of 15,000 revolutions per minute (rpm).

Flexible couplings are used to link two rotating shafts that are not aligned in order to transmit the rotational power, known as torque, from one shaft to the other. Most flexible couplings consist of two hubs and a middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the two shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from one shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from one type of misalignment to another. Flexible couplings are used in a broad range of applications, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Lovejoy manufactures flexible couplings, universal joints, variable speed drives, and other transmission and mechanical power products. The company, founded in 1900, is headquartered in Downers Grove, IL.
