MTJ series are Linear Units with a toothed belt drive and an integrated zero-clearance ball rail guide. Compact dimensions provide high load capacities, high speed, accuracy and repeatability. These Linear units can also be combined to various multi-axes linear systems and ensure an excellent price/performance ratio with short delivery time.
A High accurately extruded compact aluminium profile of hard anodized Al 6063 alloy with an integrated zero-clearence Ball rail system enables high load moments and optimum running to move large loads at high speed. Aluminum profile contains T-slots for linear unit and proximty switch fixing. T-slot suitable for reed switch too.
MTJ linear units use a pre-tensioned AT polyurethane tooth belt with steel tension cords and Polyamide fabric on teeth. This type of linear belt is used together with a Zero-backlash pully to achive an excellent precision, high load transmission with dimensional stability, low noise and low wear.

Beside in the profile groove guided Polyurethane belt protecting internal parts against dust and foreign parts Linear units can additionally be equiped with a Corrosion-resistant protection strip in order to achive an excellent protection.
Different carriage lengths with central lubrication port enable maintenance and possibility to attached various accessories.
Linear Units MTJ are available with already pre-designed adapters for attachment of motor and gear reducer in various directions.
