Maximum values apply to the corresponding size and version and cannot be combined arbitrarily. Fx acts in the direction of travel. Fy/Fz are transverse forces; Mx/My/Mz are moments about the respective axes. ¹ BK: dynamic guide values; static limits are listed separately in the datasheet. ² BK-1 Heavy: strokes above 1,800 mm require a special version and reduced speed. See the datasheet.

Questions about timing belt axes and motor connections.
What is a timing belt axis?
A timing belt axis is a linear axis that converts rotary motion into linear motion through a timing belt. A guide supports the loads on the carriage. Typical tasks include transport, positioning and handling movements.
Which timing belt axis suits my application?
Stroke, load, speed, acceleration, load position and installation orientation determine the choice. Compare BK and MTB for compact guide arrangements, MTE and MTS for higher transverse forces and moments, MTF for low installation height and MTZ for vertical motion. Final selection is based on the actual load conditions.
Which strokes and repeatability values are available?
According to the datasheets, MTB, MTE and MTS offer strokes up to 6,700 mm, MTF up to 6,000 mm, BK up to 3,800 mm depending on version, and MTZ up to 1,500 mm. Repeatability is ±0.05 mm for BK, MTB, MTE, MTS and MTF, and ±0.10 mm for MTZ. Values depend on the series and version.
What is the difference between MTE and MTS?
MTE has an additional external recirculating ball guide. MTS has a double external recirculating ball guide with higher specified transverse-force and moment limits. Selection must also consider forces and moments acting simultaneously.
What is the difference between MTF42 and MTF42D?
MTF42 is a low-profile timing belt axis with one carriage. MTF42D has two separate carriages for mirrored motion. Both are available with guide variants H and L, which differ in the number of ball guide blocks per table unit and their moment limits.
Are timing belt axes available with motors or for customer-supplied motors?
GUNDA supports combinations with stepper or servo motors and adaptation to a customer-supplied motor. We need a motor drawing or CAD data for flange adaptation. Motor, coupling, speed and connection are sized together.
Are vertical movements and multi-axis systems possible?
The MTZ series is designed for vertical motion. Individual axes can be combined into multi-axis systems. We coordinate the axis arrangement, guide loads and drives, together with any required holding or braking concept, for the specific project.
How do I enquire about a timing belt axis and where are the datasheets?
PDF datasheets are available in the comparison table and with each series. Send us the stroke, moving mass, speed, acceleration, installation orientation and load position. If you want to use your own motor, include its drawing. We will then agree the appropriate version and quotation with you.
