ADJUSTABLE CARRERA 2 PULLEYS

Technical Characteristics

The pulley is fixed with a clamping grub screw, without requiring specific machining. Micrometrically adjustable, it enables moving the sash vertically in an overall range of on average 4 mm (see adjustment column in the table). Adjustment is easy since the adjustment screw is located inside the yellow centring element which facilitates insertion of the key. The adjustment can also be made with the sash already mounted and installed. The wheels are normally mounted on ball bearings or needle bearings depending on the model and can be removed together with the support without having to disassemble the pulley. The wheels with bearings are shielded to keep the grease inside them.
