How to choose Set collar

Points to check when selecting, with the values for this product (SCK1615C).

  1. 1. Select a bore matching the shaft diameter

    This product: Inner diameter d 16 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 4300 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

    This product: Permissible radial load 33.1 N·m

    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.
