distributed by Product description Product description Linear unit with toothed belt drive Bearing housing A Attachment Basic profile Bearing housing A Toothed belt Carriage plate Toothed belt holder Figure 1: Sub-assemblies of the Beta linear units with toothed belt drive A mechanical linear drive converts rotation into linear motion and thus facilitates fast, safe and accurate movement of loads from one position to another.
distributed by Transport and storage Transport and storage The mechanical linear drive is a precision instrument. Any heavy impact to this instrument may damage the mechanics and impair its functionality. Risk of damage by heavy impact or bending! Only transport an assembled linear unit using transport locks. In order to avoid any damage to the linear unit when storing or transporting it, the following measures must be taken in order to protect it from jolting or slipping:...
distributed by Assembly and alignment Assembly and alignment The linear unit can be mounted as follows: With mounting brackets With screws in the sliding blocks With screws in the factory-fitted threaded rails Mount the linear unit only on a flat surface. Standard parallelism <0.2 mm/1000 mm.
distributed by Assembly and alignment Screwing linear unit into place from underneath Figure 3: Sliding blocks (1) in the slot on the underside of the basic profile Secure the linear unit using fastening screws from below using the sliding blocks or the threaded rails in the basic aluminium profile (Figure 3).
distributed by Assembly and alignment Setting the maximum stroke Risk of serious injury from overturning transport devices. Should the carriage come to a stop beyond the safety area, the transport device mounted on this may break off or overturn. The linear unit can be damaged beyond repair.

distributed by Assembly and alignment The limit switches must trip so that the carriage comes to a stop immediately short of the safety area. At delivery, the safety area is marked with a band (3). Proceed as follows Switch on the power supply for the limit switches. Loosen the fastening screws for the limit switch.
distributed by Assembly and alignment 6.3.2 Adjusting the position of the mechanical limit switches Mechanical safety limit switches (NC) must be used if there is a risk that persons may be endangered unless the electric drive shuts down immediately. The drive may be started up only once all limit switches are correctly adjusted and are connected! Mechanical safety limit switches may be combined with inductive limit switches.

Proceed as follows Switch on the power supply for the limit switches. Loosen the clamping screw for the retaining plate (Figure 5).
distributed by Assembly and alignment Installing the drive Make sure that the direction of rotation of the external drive corresponds to the direction of rotation of the spindle or the toothed belt, so that the limit switches operate correctly. Safety area Carriage with direction of travel plus and minus from the reference point 0...

distributed by Assembly and alignment Proceed as follows Place the motor and the coupling elements in the mounting position alongside the linear unit. Check the direction of rotation of the motor. It must correspond to the safety limit switches (Figure 6). Change the direction of rotation of the motor if required.
distributed by Commissioning Commissioning Risk of injury or damage to other installation parts as a result of quick linear motion of the transport device due to load thrown out. Only authorised personnel are permitted to commission the linear unit. Risk of crushing due to incorrect direction of movement of the transport device.
distributed by Operation Operation The drive motor can heat up considerably during operation. In this case, refer to the operating instructions supplied for the drive motor. In addition, hazards can occur due to noise, tilting and falling, failure to observe ergonomic principles, and the surroundings in which the unit is used.
distributed by Maintenance 10 Maintenance Around all rotating parts, e.g. GX shaft and around the toothed belt (when used without cover band), there is a risk of being pulled in, and of clothing or body parts being caught up and trapped. There is also a risk of crushing around the moving carriage.
