Bellows couplings are one form of flexible coupling with twin coupling ends called hubs capping a precision-engineered corrugated tube that serves as the coupling body. Bellows couplings are known for their exceptional torsional rigidity to accurately transmit velocity, angular position, and torque. Their slight flexibility (at the corrugated bellows) serves to address limited amounts of […]

What are roller chains? Technical Summary for Motion Engineers
Updated April 2015. || In any motion control system, the object is ultimately to move some kind of load. The component in the motion system that converts electrical energy into mechanical energy is the motor. But the task doesn’t end there. A motor’s output shaft has to connect somehow to whatever the load is. This […]
What are industrial bearings? Technical summary for design engineers
Updated May 2015 by Lisa Eitel. || Industrial bearings are simple machine elements but are crucial for motion applications. The purpose of a bearing is to reduce frictional forces between two moving parts by giving a surface something to roll on, rather than slide over. A bearing consists of smooth rollers or metal balls and […]
What are Linear Bearings?
Linear bearings generally use a pad, bushing, or roller system to carry a load on a rail that need not be a straight line. The rail can be most any length, although that dimension is limited by the actuator. The durability of the bearing is determined by the load and required speed. Furthermore, rails can […]
What are ballscrews? Summary for design engineers
Updated May 2015. || Ballscrews are used to change the direction of motion—from either rotational motion to linear motion or linear to rotational. The advantage of ballscrews is that they accomplish this function with minimal friction. The basic components of a ballscrew are a nut, a screw with helical grooves, and balls (often made from […]
