maxon motor - Miniature Spindle for Linear Positioning Tasks

The GP 6 S spindle gear is suitable for a wide variety of linear drive solutions.

The maxon GP 6 S spindle gear


The GP 6 S micro spindle gear has a diameter of six millimeters and is now also available in a metal version to provide a spindle drive with optimized value.

Spindle drives are the perfect solution for linear positioning systems, lens adjustment, or syringe pumps. If the drive also has to be compact, then maxon motors GP 6 S spindle gear is the perfect choice. To provide a cost-effective alternative to the ceramic version, it is now also available with a metal spindle.

Combinations with maxon DC motors

The GP 6 S spindle gear is suitable for a wide variety of linear drive solutions. The maximum feed velocity is 15 mm/s, at a force of 10 N. Integrated ball bearings ensure that this drive stands up to high axial loads. The gear easily combines with the maxon DC brushed motor (RE 6) and DC brushless motor (EC 6).

More data and details about the new metal version of the GP 6 S spindle gear are available online at Maxon's website.

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
