Cable gland screw Rittal 4055633 with ball bearing

Rittal cable gland screw with integrated ball bearing is a fastening screw designed for mechanical connections that require smooth rotational movement. It is intended for use in enclosure and panel assemblies where pivoting or rotating joints are present. The built-in bearing reduces friction and wear, delivering more consistent motion and extending component service life in industrial and electrical installations.

Advantages

The integrated ball bearing lowers rotational friction compared with standard fastening screws, which helps reduce wear on mating parts and provides smoother operation over time. Its compact design allows installation in confined spaces typical for control cabinets and electrical enclosures. Manufactured to Rittal quality standards, the screw offers dimensional consistency for reliable fit and repeatable performance in assembly processes.

Suitable for

• Fastening pivoting doors or panels on enclosures and cabinets
• Mounting moving connector interfaces or strain reliefs where rotation is required
• Applications in industrial control and switchgear assemblies
• Retrofit or replacement of worn pivot fasteners in electrical housings

Key specifications

• Fastener type: screw with integrated ball bearing
• Primary function: enable smooth rotational movement and reduce friction
• Typical application area: electrical enclosures, control cabinets, panels
• Design attributes: compact form factor suitable for tight mounting spaces
• Material and finish: engineered for mechanical durability and stable performance

How to use

Install the screw into the designated threaded hole or mating nut and tighten to the torque recommended for the assembly to ensure secure fastening while preserving bearing function. Align the rotating component so the bearing carries the intended radial or axial loads; avoid overloading beyond the mechanical limits of the screw and bearing. If replacing an existing fastener, verify thread compatibility and clearances before installation.

Usage recommendations

For optimal performance, ensure mounting surfaces are clean and free of debris, apply the correct tightening torque, and avoid exposure to corrosive environments unless appropriate protective measures are used. Periodic inspection of the bearing and surrounding assembly is recommended to detect wear or contamination and maintain reliable rotational movement.
