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.

Shrink disc ST inner diameter 40mm PN: 61584000
Material: High quality steel 42CrMo4.
- For fixing a hub (e.g. drive wheel, rotor or similar) on a shaft.
- For medium torques.
- Quick mounting.
- Quick dismounting.
- No axial offset during mounting.
Roughness: max, RZ=16 μm. Outer-Ø tolerance of hub = h9.
Recommended tolerances for hub bore / shaft diameter: from dw Ø 30 = H6/j6; Ø 31-50 = H6/h6; Ø 51-65 = H6/g6.
It is essential to degrease the contact surfaces of shaft and hub bore. Lubricate only the shrink disk and the screws with MoS2 and place it on the hub. Turn in the screws evenly by hand. Surface Roughness, Tolerances and Mounting Fasten the tensioning screws evenly, in sequence (not crossing over) until the fastening torque TA of the table is reached. To reach the value of TA, several fastening steps are required. The figures for T stated in the table were calculated for a lubricated shrink disk.
