Questions and answers
When will this part ship?
The stock status is shown next to the price. In stock parts ship from Bradenton, Florida, the same business day for orders placed before 2:00 p.m. Eastern. Backorder parts usually ship within 1–2 weeks.
What does shipping cost?
Shipping is calculated at checkout based on weight and destination. We ship with UPS and FedEx, and heavy orders ship by LTL freight. You can also ship on your own UPS or FedEx account for a $10 handling fee.
Can this part be bored or keyed to fit my shaft?
For most gears, sprockets, pulleys and couplings, yes. We can bore to your size and tolerance, cut a DIN 6885 keyway and add set-screw threads. We also offer expedited rework services for many parts. Email us the exact size needed and we will quote it.
Is there a better price for larger quantities?
Yes. The quantity prices are listed above. For more than the largest listed quantity, or for a custom version, ask for a quote.
Where are the CAD model and the catalogue page?
Under the Description tab you will find the link to free 2D and 3D CAD models and the catalogue page as a PDF.
Do you have this part in another size, material or in inches?
Often, yes. Use the filters on the category page, or send us your requirements and we will find the closest part or quote a custom one.
Can I return this part?
Unused standard parts can be returned within 30 days with an RMA number from returns@maedlernorthamerica.com; a 15% restocking fee applies. Custom-made parts or belts/chains that were cut to size cannot be returned. See our Return Policy.

Servo worm gear unit ZM/S size 40 i=39:1 output shaft with shrink disk side 6 PN: 42104117
These servo gearboxes are characterised by high torsional rigidity and very low torsional backlash. This enables high acceleration and precise positioning accuracy in your application.
General data: Universal heavy-duty worm gear boxes. 4 sizes, centre distance 40, 50, 63 and 80 mm. On request with keyway in the hollow shaft and centre distance 100mm available. Permissible ambient temperature -20°C to +40°C.
Housing: High quality aluminium die-casting, all sides machined and with mounting holes on 5 sides.
Gearing: 6 ratios from 4,0 to 39,0 : 1. Worm shaft hardened and ground, worm wheel made of high-performance bronze, Gear backlash <6 arcmin. On request, at extra cost and depending on size, the backlash can get decreased by the factory <2 arcmin.
Efficiency factor: The efficiency factors stated in the selection tables are guideline values for properly run-in and lubricated gearboxes at operating temperature with nominal load and driving worm shaft.
Self-locking: The servo worm gear unit isn‘t self-locking.
Bearing Systems: Generously dimensioned ball-bearings for continuous modes. Input side with fixed and loose bearing, output side bearing in eccentric cover. On request available with tapered roller bearing for dynamic operation and high external force.
Lubrication: On delivery with food-grad lubricant NSF-H1 filled (FDA approved). On request, the gearbox can be filled with other lubricants at the factory. Under normal operating conditions, no maintenance is required.
Ventilation: No ventilation screw necessary. The venting is effected by hermetic pressure compensation (Membran), The membran is independent from the mounting position and in the housing integrated.
Delivery: 2 products have to be ordered:
– the servo worm gear unit with shrink disc on the output side 5 or 6.
– the motor adaptation with coupling, flange and fixing screws.
1) permittable output torque T2 zul. under consideration of thermal limits.
2) maximum output torque T2 max. without consideration of the permissible torque of the coupling and the output side shrink disk.
3) with a service life of 12.000 hours and continuous operating S1 at 1.500 min-1.
