POSI LOCK PSL-D(C) Type Simple Anti-Corrosion Specification

Specifications

How to choose Friction fastener

Points to check when selecting, with the values for this product (POSI LOCK PSL-D(C) Type Simple Anti-Corrosion Specification).

1. 1. Select the Applicable Shaft Diameter

   Friction clamping devices are sized for each shaft diameter, and the listed products cover a range of 19 to 120 mm. Shaft tolerance and surface roughness affect frictional force, so confirm that the shaft meets the tolerance specified by the manufacturer. When using a hollow shaft, check whether it will deform under contact pressure.

2. 2. Allow Margin in Allowable Torque

   This product: Allowable torque Mt 67～1760 N・m

   The maximum transmittable torque for the listed products is 6 to 1760 N·m. Consider starting shocks and fluctuating loads, and select a size whose allowable torque is at or above the actual torque multiplied by a service factor appropriate to the nature of the load.

3. 3. Verify Combined Thrust Load

   This product: Allowable thrust force Pax 8400～70300 N

   Axial force is also transmitted by friction, so check the allowable thrust force (listed range 2100 to 70300 N). When torque and thrust act simultaneously, evaluation is generally based on their combined effect, so verify against the manufacturer's calculation formula.

4. 4. Check Hub Outer Diameter and Strength Against Contact Pressure

   The outer diameter of the clamping device corresponds to the hub bore diameter. Because contact pressure from the outer ring acts on the hub, determine the minimum hub outer diameter from the hub contact pressure and the yield point of the hub material. If a smaller outer diameter is required, refer to the types that include a minimum hub outer diameter selection table.

5. 5. Confirm Overall Length Relative to Hub Width

   Confirm that the axial overall length of the clamping device fits within the hub width, and that there is sufficient space for bolt heads and tools. If the hub width is insufficient, the contact area is reduced and the specified transmission capacity cannot be achieved.

6. 6. Tightening Torque Control and Operating Environment

   This product: Clamping bolt tightening torque Ma 4～34 N・m

   The clamping bolts must be tightened evenly to the specified torque (listed range 1 to 34 N·m); insufficient tightening causes slippage. The listed products have an operating temperature range of -40 to 150 °C. In humid environments, select specifications with rust-preventive treatment such as electroless Ni plating.
