Tirante Rittal 4055631 con cuscinetto a sfere

The Rittal cable tensioning screw with integrated ball bearing is a mechanical fastener designed for controlled tensioning and smooth rotational movement in enclosure and panel installations. It secures cables or components where predictable mechanical behaviour is required and is intended for industrial electrical environments where robust, repeatable performance is necessary.

Advantages

The built-in ball bearing reduces friction and wear during rotation, enabling precise adjustment and longer service life compared with plain threaded screws. Its construction provides consistent clamping force and stable positioning under repeated use. The part is compatible with standard panel and enclosure mounting practices used in industrial electrical assemblies.

Key specifications

How to use

Install the tensioning screw into the designated threaded insert or nut within the enclosure or panel. Route the cable or position the component to be secured, then rotate the screw to achieve the required tension or position. The ball bearing facilitates smooth turning; adjust incrementally until the desired clamping force and alignment are achieved. Verify that the screw head and bearing run freely and that the secured cable or component is held firmly without pinching or damage.

Recommendations

Use appropriate torque control during tightening to avoid over-stressing the screw or mating threads. Periodically inspect the bearing and threaded interfaces for corrosion, contamination, or wear when used in harsh environments, and replace the part if smooth rotation or secure clamping is compromised.
