Chain racks

Good value, flexible, and robust

Advantages

  • Less sensitive to tooth backlash changes. Alignment errors can thus be corrected through smaller sprocket widths.
  • High level of acoustic insulation
  • High stability
  • Cage profile can expand if temperature varies
  • Simple assembly
  • Economical alternative to milled racks

Design

The clamping set is connected with the actual chain rack using a simplex chain connecting link. The chain is guided using a cage profile made of Original Material "S"®1000 Green. This is clasped by a steel C profile from the outside. The steel C profiles are fixed to the base using clamps. For chain lengths of more than 2,500 mm, fastening brackets are also provided. They are integrated into the rack using duplex connection elements. This prevents the chain rack from moving in the cage profile during start-up and deceleration. Chain racks are available in chain sizes of 1/2", 5/8", 3/4" and 1".

Our chain racks have more than proven themselves as an economical alternative to milled racks. The system is characterized by ease of installation and simple adjustment, and is attached using an anchor plate at one end and a clamping set at the other end.

Full speed ahead – the tangential force on the sprocket

The correct choice of sprocket is vital in order to ensure the optimum flow of forces and maximum durability of your components. To keep the contact ratio as favourable as possible, the sprocket must have lantern gear toothing. 15 is recommended as the minimum number of teeth. The optimum value is N 19.

For all necessary information on calculating values for your chain racks, see the Products section of our Web site. We are happy to provide you with personalized advice. Please contact us.

DIN 8187 chain no. Chain dimensions in inches Clamping nut fastening torque Clearance between tooth base and chain roller Max. tangential force*
08B-1 1/2" x 5/16" 3 – 5 Nm 0,3 – 0,5 mm 2700 N
