Umakov toothed rack, plastic-coated, with steel core, module 4, 20 × 27 mm

The toothed rack is fixed to the sliding gate along its entire length. The operator pinion engages in the rack and so moves the gate. The rack has a nylon surface with a steel core and a module 4 tooth pitch. It is suitable for operators with a module 4 pinion on gates up to 700 kg.

When to choose a different rack

• Fixing high above the operator – choose the rack with top fixing, which has lugs pointing upwards.
• Came BX and BK operators – Came offers the Came V6 and Came CGZP racks with the same cross-section and module, for gates up to 1,000 kg.
• Heavier gate – choose the 30 × 12 steel rack for up to 2,200 kg.

Installation

1. Release the operator and lay the rack on the pinion.
2. Screw the rack to the gate along its entire length. The pack contains 6 self-drilling screws 6.3 × 32 mm with washers. Additional screws with washers are in the rack fixing kit.
3. Support the joint between two pieces with a short piece of rack so that the teeth line up.
4. Set the clearance between the pinion and the rack according to the operator instructions, and only then fix the operator firmly.

For a gate on an incline, add the BSF-M hydraulic brake, which engages in a module 4 rack. In the Košice and Prešov regions we install the gate with the operator, more on the page.
