Tension screw with ball bearing Rittal 4055630 Ø6 mm L40 mm

Rittal tension screw with ball bearing 4055630 is a precision fastening element with a nominal diameter of 6 mm and an overall length of 40 mm. The part integrates a ball bearing to provide smooth, low-friction rotation and accurate clamping in electrical enclosures, mounting frames and industrial assemblies. It is intended for applications that require repetitive adjustment, pivoting movement or secure tensioning while maintaining alignment and minimal wear.

Advantages

The integrated ball bearing reduces friction and wear during rotation, providing consistent movement and longer service life compared with plain screws. The 6 mm nominal diameter and 40 mm length offer a compact solution that fits standard mounting points in enclosures and frames. Manufactured by Rittal, the component is designed for mechanical stability and repeatable adjustment under typical industrial conditions.

Suitable for

• Adjustment and tensioning of enclosure doors, panels and hinges
• Pivot points in mounting frames and cabinet interiors
• Industrial assemblies requiring low-friction rotational movement
• Applications where precise alignment and secure clamping are required

When it may not be suitable

This tension screw is not intended for structural load-bearing applications where certified load ratings or specific tensile strengths are required. It may not be suitable for environments with aggressive chemicals, extreme temperatures or where special corrosion-resistant materials are mandated unless additional protective measures are applied.

Key specifications

• Nominal diameter: 6 mm
• Overall length: 40 mm
• Integrated ball bearing for low-friction rotation
• Application type: tension/adjustment screw for enclosures and frames
• Suitable for industrial and electrical enclosure assemblies

How to use

Install the tension screw by inserting it into the corresponding threaded or through-hole on the enclosure or mounting frame and tighten to achieve the required clamping force. Use appropriate tools that match the screw head type and avoid over-torquing to prevent damage to the bearing or surrounding components. For pivoting applications, ensure the mating surfaces are clean and aligned so the integrated ball bearing can operate with minimal friction.

What to consider before purchase

• Confirm the 6 mm diameter and 40 mm length match your mounting dimensions
• Verify compatibility of the screw head and drive type with your tools
• Assess environmental conditions (temperature, humidity, chemicals) for material suitability
• Ensure the component meets your mechanical and alignment requirements rather than primary structural load-bearing needs

Usage recommendations

For reliable operation, keep the bearing area free of debris, apply suitable lubricant if permitted, and follow recommended torque ranges for small fasteners. Regular inspection during maintenance cycles will help maintain smooth rotation and secure clamping in enclosure and frame applications.
