How to choose Set collar

Points to check when selecting, with the values for this product (Standard Slit Collar / Standard Separate Collar Technical Data (Normal and Thrust)).

1. 1. Select a bore matching the shaft diameter

   This product: Inner diameter d 5〜110 mm

   Select the bore d to match the applicable shaft diameter. Listed products cover a range of φ5 to 110. Because the combination of shaft tolerance and collar bore tolerance affects clamping force and ease of fitting, check the bore tolerance as well as the shaft diameter.

2. 2. Confirm the required axial holding force

   This product: Allowable thrust load 149,040 N

   The allowable thrust load is the axial load that can be held without slipping axially, and listed products range from 2300 to 149040 N. Even with the same bore, values differ by type; for example, at φ30 there are products rated at 5400 N and 2300 N. Select a model with sufficient margin over the axial load applied.

3. 3. Also check rotational holding force

   The allowable radial load is the torque that can be held without slipping in the rotational direction, and listed products range from 3.6 to 449.5 N·m. In applications where torque or rotational force acts on the collar, confirm that this value exceeds the operating conditions.

4. 4. Choose the clamping method based on how often it is adjusted

   For positions that change frequently, the lever type is convenient because no tools are required, but its holding force is lower than with bolt tightening. The listed lever-tightened thrust load is 780 to 2300 N. If the shaft must not be damaged, select the clamp or wedge type.

5. 5. Tighten to the recommended torque

   This product: Tightening torque 0.9〜267.2 N・m

   The holding forces in the catalog are values obtained when tightened to the recommended tightening torque. Listed products range from 0.9 to 267.2 N·m, and the value varies greatly with bolt size. Using a torque wrench to observe the specified value helps prevent loosening and damage to the body.

6. 6. Select material and surface treatment suited to the environment

   S45C offers high strength and is protected against rust by black oxide or electroless nickel plating. For humid environments or areas with washdown, SUS304 is chosen, and for weight reduction, aluminum alloys such as A2017 are selected. However, holding force varies with material, so check it together with the load values.

About Set collar and all products

Description

Technical data for set collars fixed to shafts by tightening bolts. Tightening torque is shown by bolt size for S45C, SUS304, A2017 and POM materials. Thrust values are experimental results from compression tests using hardened shafts, and material-specific data are provided for both the SCS and SCSS series. These are not guaranteed product performance values; safety must be confirmed by testing before actual use.

FAQ

Q. What reference values are available for the axial thrust of the Standard Slit Collar (Normal and Thrust) by material?

A. Thrust values are experimental results from compression tests using hardened shafts, and material-specific data are provided for both the SCS and SCSS series. These are not guaranteed product performance values, so safety must be confirmed by testing before actual use.

Q. How does the tightening torque of the Standard Separate Collar vary with bolt size and material?

A. Reference tightening torque values are shown by bolt size for S45C, SUS304, A2017 and POM materials. The specified tightening torque ranges from 0.9 to 267.2 N·m, and bolt sizes range from M2.6 to M16.

Q. What bore diameter range do the Standard Slit Collar and Standard Separate Collar cover?

A. Reference values by material are provided for each size with bore diameter from 5 to 110 mm.
