below center), we have reduced out-ofbalance by 50 %. But smooth running is not all – the time factor is also optimized since the ready-to-mount Pulleys do not have to be balanced separately, and they have long maintenance intervals. INA tape tension pulleys are known for their long operating life. An example are our special pulleys for the gripper drive in a weaving machine (see illustration below right). The pulley is easy to

relubricate and has an extremely low moment of inertia. This allows the operating speed to be reached faster and up to 600 alternating rotary movements per minute can be performed with little energy consumption. This enables the user to increase productivity and, of course, maintain the same fabric quality. We have developed a series of readyto-mount systems that only need to be bolted on without first having to take the time to adjust separate parts to each other.

INA friction unit bearings for texturing machines are truly economical (see illustration above). These spindle units are complete and ready to mount – and no adjustments have to be made. The special feature here is their quiet operation. Since the special two row ball bearing on the top has an integrated elastic

suspension, spindle operation is precise and resonance-free – even in a broad work range of 8,000 to 5,000 rpm, which is above the critical speed. Reducing operation noise is an important part of our product development efforts. For example, for a tape tension pulley for twisting machines (see illustration
