RACK & PINION UNITS LZG 20 // Rack & pinion units 5500 –10000 N > Extremely robust top-quality universal rack & pinion units with a very compact design. When mounted to support, cause absolutely minimal shading because input shaft is below the gutter. > Universal application for spacing of push-pull tube above beam of 40, 60 or 60/200 mm as well as C-section 11.5 mm. > The support version is easy to install by clamping to the support – support dimensions 80, 100, 120 or 140 mm x 50, 60 or 80 mm are possible. Please indicate support dimensions on order! Support mounting > Stable cast housing with ball bearings for quiet operation. Gear components of high-tempered steel, 10000 N version with additional hardening. > Hex shaft for ease of assembly of prefab tubes, low levels of torsion and clearance. Robust input shaft for the transmission of high torque levels. Securing on the beam with two bolts (by customer) with strength 8.8. > Rack made of milled steel (25 x 35 mm / 30 x 40 mm) with integrated connection for 27/32 mm push-pull tube. > Standard colour DB 701 (platinum grey). > The rack is delivered pre-greased. Including tensioning pin Rail mounting Support mounting module Gear unit Rail mounting module LOCK BEWEGT // LOCK MOVES
