NORELEM FRANCE - Leader mondial des composants standard destinés à la construction et à l’ingénierie mécanique

Handwheel, reinforced and stabilised polyamide. Centre caps, polyamide. Centre bushes, steel. Tapped insert for cylinder grip, brass. Version: Handwheel, oil and grease resistant, black (RAL 9011), satin finish. Centre caps, grey (RAL 7035). Centre bushes, black oxidised. On request: Other cap colours. Special versions.

The hub cover is supplied loose. The handwheels can be secured using a transverse pin or by parallel key connection together with a DIN 6912 socket head screw and a DIN 7349 washer. Versions with transverse bore are secured using the ISO 4026 (DIN 913) grub screw. For assembly example, see 06262.

1.4401 stainless steel, similar to DIN 39. Grip suitable for DIN 950 handwheels.

Crank black powder coated. Thermoplastic black. Steel parts black oxidised. Note: Similar to DIN 469.

Tension levers can be used for simple clamping or control operations. Where applicable, there must be enough space available so that the grip can be rotated 360°. On request: Other internal threads, reamed holes and special versions. Dimension “A” available in other lengths at extra charge.

Other threads, screw lengths and special versions. Dimensions “H1” and “A” available in other lengths at extra charge.

Handle powder-coated, fine-textured structure. Steel parts black oxidised. Note: Standard colours are: black or ruby red RAL 3003.

Traffic red clamping lever, black grey push button. Where L ≥ 60 mm the thread length is 60 mm. On request: Other threads, screw lengths and special versions. Dimension “H1” available in other lengths at extra charge. Drawing reference: 1) flat point DIN 78

By using clamping levers with integrated clamping force intensifier, the clamping force can be increased by up to 75% compared to standard clamping levers. Furthermore, this product can also be used by persons with limited hand strength (e.g. in rehabilitation) to achieve comparable clamping forces with less effort. Less effort is also needed to loosen the clamping lever. The increase in clamping force is achieved by the integral needle roller thrust bearing, which generates very low surface friction on a rigid contact surface during clamping. The hardened thrust washers are designed for high clamping forces and the bearing with its high load rating guarantees a long service life. The clamped component is permanently protected by the large, stationary contact surface. A washer is no longer required. Due to the modular construction many special designs are available.
