Tension Screw with Ball Bearing Rittal 4055634 Ø19 mm L=75 mm

Rittal tension screw with integrated ball bearing, nominal diameter 19 mm and length 75 mm, designed for axial fastening and to enable smooth rotary movement in enclosures, industrial cabinets and mechanical assemblies. This component combines a threaded tension element with a thrust-capable bearing surface, making it suitable as a replacement part or for maintenance tasks where dependable axial load transfer and precise alignment are required.

Advantages

The integrated ball bearing reduces friction during rotation and provides consistent axial support, improving longevity of moving parts. Its 19 mm diameter and 75 mm overall length deliver a compact solution that fits common enclosure and cabinet geometries while offering reliable mechanical strength. Constructed to meet industrial application needs, the tension screw simplifies assembly and replacement thanks to a standardized form factor and straightforward installation.

Suitable for

• Axial fastening and preload in electrical enclosures and control cabinets
• Rotary or pivoting elements in mechanical assemblies requiring low-friction movement
• Replacement parts during maintenance of industrial cabinets and housings
• Applications where alignment and controlled axial thrust are necessary

When it may not be suitable

This tension screw is intended for applications that match its 19 mm diameter and 75 mm length; it may not be suitable where different dimensional requirements or non-standard thread profiles are specified. It is also not intended as a primary load-bearing component for heavy structural supports beyond typical cabinet or enclosure hardware loads.

Key specifications

• Nominal diameter: 19 mm
• Overall length: 75 mm
• Integrated ball bearing for reduced friction and axial support
• Designed for axial fastening and smooth rotary movement
• Intended for use in enclosures, industrial cabinets and mechanical assemblies

How to use

Install the tension screw in the mating threaded hole or nut, ensuring thread compatibility and correct engagement. Tighten to the appropriate torque specified for the receiving material to achieve the required preload while avoiding over-torquing that could damage threads or the bearing. For rotating applications, confirm the bearing rotates freely after installation and that any associated washers or retaining elements are fitted according to the assembly design.

What to consider before purchase

• Verify the 19 mm diameter and 75 mm length match the application's dimensional requirements
• Check thread type and pitch in the receiving component for compatibility
• Confirm bearing function is suitable for the expected rotational speed and axial load
• Assess material and surface treatment requirements based on environmental conditions (e.g., humidity, corrosive atmosphere)

Usage recommendations

For reliable performance, use appropriate torque settings and periodic inspections: verify bearing rotation and thread integrity during routine maintenance. Replace the screw if bearing roughness, excessive play or thread wear is observed to maintain safe and precise operation within enclosures and mechanical assemblies.
