7791 - Mechanical Base Unit From 1 to 400 N m, registered design - Stahlwille

The Stahlwille 7791 Mechanical Base Unit (Model Number: 52110091) is a professional-grade calibration system designed for the precise testing and adjustment of torque wrenches and torque screwdrivers from 1 to 400 N·m. Engineered with a modular "slot-in" design, this base unit offers exceptional versatility, allowing technicians to configure and expand their calibration setup according to specific operational needs.

Key Features

• Modular and Expandable Design: The unit's modular construction enables end-users to customize their mechanical loader with additional components, ensuring adaptability to evolving calibration requirements. All components are carefully matched for compatibility and ease of assembly.
• Patented Linear Force Application System: A specially designed force transmission system prevents the point of force application from shifting during the calibration process. A handwheel-driven spindle actuates a lever, translating linear motion into rotary force while the torque tool remains stationary, significantly reducing measurement errors.
• Enhanced Accuracy with Frictionless Bearings: Low-friction linear ball bearings automatically level the torque wrench and ensure friction-free contact. This design minimizes transverse forces on the transducer and friction at the contact point, leading to highly accurate and repeatable calibration results.
• Secure and Easy Assembly: The "slot-in" system provides a very accurate fit, and components are quickly locked together using integrated screw joints, ensuring stability and ease of use.
• Ergonomic Display Unit Placement: The display unit can be attached at various points on the system via a holder, allowing users to optimize their work environment for comfort and efficiency.
• Professional-Grade Durability: Constructed with the robust quality synonymous with Stahlwille, this unit is built for longevity and reliable performance in demanding professional and industrial settings.

Applications

The Stahlwille 7791 Mechanical Base Unit is an essential tool for automotive, aerospace, and manufacturing workshops, as well as dedicated calibration laboratories. It is used by professional technicians and mechanics for routine calibration, adjustment, and verification of torque wrenches and torque screwdrivers, ensuring fastening tools meet precise torque specifications for critical assembly and maintenance tasks. This system helps maintain tool accuracy, prevent over- or under-tightening, and comply with quality assurance standards.
