INA KWEM 7, 9, 12 and 15            and            INA KWVE 15, 20 and 25


As each linear design has particular characteristics that make it especially suitable for particular bearing arrangements.  Rules for selecting the type of guidance system can only be formulated up to a point, more factors must be taken into consideration and weighed up against each other. Apart from load, acceleration, speed and stroke, factors including temperature, lubrication, vibration, mounting, maintenance etc. must also be taken into consideration. ina-5 ina1 ina2

Linear Belting

All types of linear belting are available with a wide range of backings.  Truly endless or joined options are also available.  Conveyor belts are available either ex-stock, special procurement made to order or tracked type.

The optibelt ALPHA LINEAR timing belt can also be given a thin fabric covering on the tooth side in order to reduce friction and noise. Fabric can also be applied to the belt back.  The belts are dimensionally stable and their precise positioning makes them ideal for use in linear drive systems.

Optibelt is the world leading manufacturer of industrial linear belting technology offering superior quality, best in class technology/materials, shorter lead times and value for money.
