Manufacturing Collar

You have chosen the coupling with specification however bore diameter is not in catalogue or having trouble with delivery date. We can solve those problems with manufacturing collar. Please see the note and reference for inquiry of collar.

Manufacturing type

Following couplings are possible to manufacture the collar.

MJ series
N coupling serie

JK JKW series
AHS AHD AHT series


Size

Collar

Please refer the basic information blow of minimum bore and thickness for specification. Each collar size of bore must be over 5mm, and products bore must be under 50mm.

Shaft diameter ( bore ):
Min 5mm - Max 50mm
Collar thickness ( thickness ):
Min 1mm - Max 5mm

Material and Heat treatment

S45C is used as main material. Please use the same or higher yield point material. If you are planning to use the material over S45C, then the material must be normalized.

Dimensions

Please refer the size below for manufacturing the collar.

Dimensions

  • Please refer the drawing below for slitting location to increase the contraction of thickness.
  • The tolerance of shaft diameter is plus of 35mm bore coupling. ( for motor shaft )
    Please process the outer diameter of collar with φ35.035 - φ35.045.

The table of maximum transmission torque capacity with collar

Please calculate with below reference when you install the collar to coupling and torque capacity is deceased.
*AS40A AW-40A of torque capacity are the same with collar.

<Flexible coupling>

Disk spring type of Maximum torque capacity indicates torque of only part of disk spring. If you install the collar, the maximum torque could be lower than shaft slipping torque. Please calculate the maximum torque with below formula, when you use the collar.

Collar torque = Shaft slipping torque × d(Bore of collar) × 0.7
D(Collar outer iameter)

*Example of torque capacity when you install the φ12-10 collar to AH65-12

  60 × 10 × 0.7 = 35 Torque capacity will be 35N·m
