spring

Tension spring< /span>

Load P [N] = initial tension Pi [N] + (spring constant k [N/mm ] × deflection F [mm])

· The specifications of tension springs (except for freely specified types) are standardized and the maximum load for the same diameter is constant. Because it is produced based on the maximum load value, the initial tension and spring constant are reference values.

· Please use it within the allowable deflection F max. (mm). If used beyond the allowable deflection, the spring may be deformed, or the spring may be damaged after a small number of uses. When installing, please note that the tension spring must not be stretched beyond the allowable deflection.

· Tension springs (AW, BW, AWFM, WFSP, LWS, LWSH) are recommended to be used at room temperature (below 40°C). When used above 40°C, the load value may attenuate depending on the conditions.

Round wire compression spring and special-shaped coil spring

Load P［N］=(Spring constant k［N/mm］×Deflection F［ mm])

· The specifications of round wire compression springs have been standardized, and the spring constants for the same diameter are constant. The spring constant tolerance is ±10%.

Rectangular spring specifications are standardized, with a constant maximum load for the same diameter. Tolerances for load values ​​vary by type, so please refer to the page for each model.

· Please use it within the allowable deflection F max. (mm). If the allowable deflection is exceeded, the spring may be deformed or damaged.

The pressing length is a reference value. If it is bent to a compressed length and used, the spring may be deformed, or the spring may be damaged after a small number of uses.

· For the coil diameter of the round wire compression spring, the outer diameter standard type has priority in the outer diameter tolerance production, and the inner diameter standard type has priority in the inner diameter tolerance production.

For the inner and outer diameter tolerances of rectangular springs, please refer to the page content of each model.

· Round wire compression springs (W□·NW□·FW□·U□·FU□) and rectangular springs (SWF·SWL·SWM·SWH·SWB) are recommended to be used at normal temperature (below 40°C). When used above 40°C, the load value may attenuate depending on the conditions. (Heat-resistant springs are listed in "Standard Parts for Plastic Types".)

· Rectangular springs are also listed in "Standard parts for stamping dies" and "Standard parts for plastic molds". (Large diameter dimensions are also listed)
