Anti creep crossed linear roller slide
item Industrietechnik GmbH
The linear unit KRF (KRF = cross roller apron) offers high carrying capacity on very small area as complete system. The narrow carrier profile from aluminum does to 40 mm without a separate guidance and uses instead four high-strength careers from steel, which are rolled in directly into the side of the X-förmigen carrier profile. The steel courses are particularly wear resistant and result in a positive group without edges, also on large stroke lengths.
Führungsschlitten, which is milled from a block from high-strength aluminum, uses eight loadable castors in cross arrangement. Here the roles are not right-angled to the carriage surface installed, but in the angle of 45° and/or 135°. Thus they run both at the upper and at the lower surface of recessing the carrier profile. By the arrangement the roles support each other mutually, because forces are not only derived in a direction.
The durable Design makes even during a load of the guidance carriage with up to 250 kg a total driving length possible of 10,000 km - and despite very compact dimensions. The linear unit KRF is propelled with a toothed belt drive. The carriage offers various mounting options and possesses an integrated stripping and lubrication system. The durable cross roles are besides very maintenance-poor, so that a lubrication is necessary only every 6 months and/or after 2500 km drive.
