New from norelem: Linear units with ball screw drive

Norelem offers a reliable solution for all applications that require linear motion and where high accuracy and load capacity are important: Compact and flexible linear units with ball screw drive now complement the extensive range of linear technology.

The new range comprises three product families: linear axes with ball screw drive and profile rail guide, the version with two profile rail guides and matching clamping strips.

The ball screw drive enables precise and repeatable positioning (repeat accuracy up to ± 0.02 mm). The low friction and high-quality materials ensure a high load capacity and long service life even under demanding conditions. Precision ball screws of tolerance class ISO 7 with reduced axial play of the threaded nut are used in the low-wear linear units. A cover strip made of antistatic polyurethane protects all parts in the profile from dust and dirt.

The modules are available from norelem in various sizes and configurations to meet different requirements - from compact solutions to larger systems. Thanks to standardized interfaces, they can be easily integrated into existing systems and combined with various drive technologies.

Linear axes with ball screw drive and profile rail guide

These are linear units with a single integrated zero-clearance guide rail system. The rail system absorbs the highest forces from all directions and offers optimum running characteristics when moving large masses - minimizing energy consumption and increasing operating efficiency. the ball screw drive and rail guide system can be easily relubricated via the central lubrication connection. The profile and accessories such as sensors can be attached to the side grooves. A ball screw support system can also be integrated to achieve higher speeds and longer strokes.

This variant is available in sizes 40, 65, 80 and 110. The maximum stroke is 5,456 mm, the maximum axial load is 29,600 N and the maximum drive torque is 52.3 Nm.

Version with two linear guideways

This linear unit has two parallel, integrated zero-clearance guide rail systems, which enable high load ratings and optimum cycles for moving larger payloads at high speed. Grooves are also provided here for mounting the linear unit and for attaching sensors and switches.

This variant is available in sizes 90, 110 and 145. The maximum stroke is 1,960 mm, the maximum axial load is 14,800 N and the maximum drive torque is 24.5 Nm.
