The ranges include several sizes and pitches. Axial force Fx acts in the direction of travel; Fy and Fz are transverse forces. Mx, My, and Mz denote the moments about the respective axes. Stroke, pitch, speed, and combined load are designed together.
¹ SK-0 and SK-2: Transverse forces and moments are static limit values. For SK-2, the dynamic values are Fy/Fz = 2,500 N, Mx = 35 Nm, and My/Mz = 250 Nm. Static axial load: SK-0 958–1,135 N, SK-2 2,800 N. For SK-0, the duty cycle and cooling of the spindle-nut combination must be taken into account.

Good to know
Questions about spindle axes and motor connections.
What is a spindle axis?
A spindle axis is a linear axis in which the rotational motion of a spindle is converted into linear motion of the carriage. The integrated guide supports lateral forces and moments. GUNDA offers spindle axes with lead screws or ball screws.
What is the difference between a lead screw and a ball screw?
In the SK-0, a self-lubricating plastic nut runs on a stainless steel threaded spindle. It is suitable for compact adjustment tasks and lighter applications. The SK-2, MTV, MUK, and MTL use a ball screw or ball-screw drive for precise movements and higher loads.
Which spindle axis series is right for my application?
SK-0 is the compact version with a slide guide. SK-2 combines a ball screw and a preloaded recirculating ball guide. MTV offers a slim, integrated guide. MUK has two guides with one or two carriages per guide and can accommodate high lateral forces and torques. MTL offers a wide mounting surface for heavy-duty applications.
Can I order a lead screw axis without a motor?
Yes. All five series are available as mechanical spindle axes without a GUNDA motor. You can have your own motor mounted or combine the axis with a suitable GUNDA stepper or servo motor.
Does GUNDA adapt the motor flange to my own motor?
Yes. We offer a service to adapt the motor flange to customer-supplied motors. For this adaptation, we need the motor drawing, including centering, hole pattern, shaft dimensions, and mounting dimensions, as well as the desired spindle axis. The coupling and mounting are tailored to the specific application.
Are spindle axes available with stepper motors and servo motors?
Yes. Our spindle axes can be combined with stepper motors featuring integrated control or servo motors with integrated controllers. The selection depends on the required force, speed, acceleration, duty cycle, and communication with the machine control system.
What travel ranges and repeatability are possible?
The SK-0 offers a stroke of 50 to 500 mm and a repeatability of ±0.15 mm. The SK-2 offers a stroke of 100 to 1,200 mm and ±0.02 mm. Depending on the size, the MTV and MTL achieve a stroke of up to 1,500 mm with ±0.02 mm. Depending on the size, the MUK achieves up to 1,500 mm with ±0.05 mm. The exact stroke ranges for each size are listed in the technical tables.
How does the lead affect the design?
The lead determines the travel distance per spindle revolution. At the same rotational speed, a larger lead results in a higher linear speed. At the same time, the required motor torque and the available axial force change. Therefore, lead, stroke, speed, and load are selected together.
Can I design the lead screw axis using the MotorFinder?
Yes. The MotorFinder supports the design process based on load and motion profile. The stroke, force, speed, acceleration, mounting position, duty cycle, and load application point are particularly relevant for configuring the spindle axis. We’ll assist you with the final selection of the axis and motor.
Are multi-axis systems and XYZ systems possible?
Yes. Spindle axes can be combined with other linear axes using suitable connecting elements to form multi-axis systems. We tailor the axes, motors, and mechanical interfaces to the required working space and motion profile.
How do I request a spindle axis, and where can I find the data sheets?
The data sheets are available for download directly in the series comparison and on each product card. Please send us the desired series, stroke, load, and motion profile. If you want to use your own motor, please include the motor drawing. We’ll use this information to configure the right axis design for you.
