PULLEY GUIDES – HIGH SPEED AND LONG ADJUSTMENT SPACE IN A LIGHT-WEIGHT DESIGN

 

LaufrollenführungPulley guides are longitudinal guides with modular construction and a light-weight design, which makes them especially suitable for use in handling systems and in automation technology. Among others, the significant application areas include:

  • Machine tools
  • Packaging machines
  • Printing industry
  • Automation, handling, robots, manipulators
  • Medical technology
  • Wood and paper industry
  • Transport and logistics

 

Their primary characteristics are high traveling speeds, a long adjustment range, consistently low sliding resistance and quiet running. These guides differ from typical rolling bearings because, in contrast to ball bearing or needle bearings, there are no rolling elements moving between the guide rails and the carriage.

Pulley guides consist of one or more carriages made of aluminium, profile pulleys and a round or straight bearing rail. The carriages can have an open, hollow, compact or bogie design for oval, curved and round guides.

The bearing rails made of aluminium, which are used to guide the carriage, include attached raceway shafts made of bearing steel. There are various design versions, including hollow rails, rails with full profiles, flat or grooved rails, etc. The design depends on the purpose of the pulley guide application.

We provide bearing rails for bearing rail supports with added guide shafts in sizes starting at 12 mm. One-piece bearing rails are available in lengths up to 6,000 mm. The following materials are used for the guide shafts:

  • Heat-treatable steels
  • High-alloy steels
  • Chromium-plated, heat-treatable steels


In the area of bearing rail supports with attached guide shafts, there are bearing rails starting at a size of 20 mm. One-piece bearing rails are also available in lengths up to 6,000 mm. The guide shafts are made of the following materials:

  • Heat-treatable steels
  • High-alloy steels


Our carriages are available in various designs. With regard to the material, you can select from aluminium with bearing steel or low-corrosion steel.
We carry profiled rollers in various sizes. To make them, we use bearing steel or low-corrosion steel.
Pins and bolts, also made of bearing steel or low-corrosion steel are available in centric or eccentric versions.
In the area of accessories we offer matching lubrication and wiping units as well as a stopper.
