How to choose Set collar

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

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 80,000 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

   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.
