How to choose One-way clutch

Points to check when selecting, with the values for this product (1WC0815).

  1. 1. Select an inner diameter that matches the shaft diameter

    This product: Shaft diameter d 8 mm

    The applicable shaft diameter of the listed products is 4 to 12 mm. Because the rollers contact the shaft surface directly to transmit torque, the shaft's outer diameter, surface hardness, and surface finish affect clutch operation and service life. Verify the shaft dimensional tolerances and surface treatment against the manufacturer's recommended values.

  2. 2. Allow margin in the load torque

    This product: Torque capacity 2.65 N-m

    The torque capacity of the listed products is 0.08 to 6.28 N·m. Even at the same shaft diameter of 10 mm, capacity ranges from 1.18 N·m for the low-load type to 2.35 N·m for the high-load type. Estimate the maximum load, including impact torque during start-up and stopping, and select a model with sufficient capacity margin.

  3. 3. Match the outer diameter to the housing dimensions

    This product: Outer diameter D1 14.2 mm

    The outer diameter is 8 to 18 mm. Because the outer ring is fixed in the housing by press fitting or molding, design the bore diameter and fit to match the outer diameter. Even at the same shaft diameter, the outer profile varies with width and load type, so confirm it together with the available mounting space.

  4. 4. Prevent creep with the outer ring projections

    This product: Number of protrusions on outer ring 6 個

    Projections on the outer circumference of the outer ring prevent creep, the phenomenon in which the outer ring slips and rotates within the housing. The number of projections is 4 to 8. The housing requires matching groove shapes for the projections, so confirm the number and arrangement on the drawing.

  5. 5. Choose the spring material and mounting method

    Metal-spring types support high loads. Synthetic-resin-spring types support insert molding (a method in which the part is embedded during molding of a resin component). When integrating the clutch into a resin gear or pulley, confirm whether the product is suitable for insert molding.

  6. 6. Check the operating temperature

    This product: Operating Temperature Range -10～+90 ℃

    The characteristics of the pre-packed grease and resin springs change with temperature. Consider internal heat generation and the installation environment, and confirm that the ambient temperature falls within the product's specified operating temperature range.
