Products/Services for Stefan-Boltzmann Constant

  • Constant Force Springs-Image
    Constant Force Springs - (38 companies)
    Constant force springs are a variety of extension spring. A strip of steel with a preset curvature is coiled tightly so that each turn of the strip rests on its inner neighbor. The spring is actuated in a pulling, liner motion with the deflection... Search by Specification | Learn More

    Constant Voltage Transformers (CVTs) - (20 companies)
    Constant voltage transformers (CVTs) or ferroresonant transformers produce a constant secondary (output) voltage for varying primary (input) voltages within a certain range. With CVTs, the saturation of the ferrous core induces ferroresonance... Learn More

    Constant Velocity Joints (CV Joints) - (16 companies)
    Constant velocity (CV) joints are mechanical power transmission components which provide rotational power at various angles. They provide the same output velocity in relation to the input velocity independent of the angle they are operated... Learn More
  • Current Limiting Diodes-Image
    Current Limiting Diodes - (37 companies)
    Current limiting diodes (CLD) regulate current over a wide voltage range. There are several types of current limiting diodes (CLD). Examples include a current regulator diode, constant current diode, and current limit diodes. Current limiting diodes... Search by Specification | Learn More

    ...stop. These types need to be oiled to reduce friction. Constant force extension springs are unique type of spring, formed of prestressed, flat metal stripping. Formed into a tight coil, when deflected the spring straightens and lengthens in a linear... Search by Specification | Learn More
  • Preload Springs, Spacers, and Washers - (91 companies)
    Preload springs, spacers, and washers are meant to maintain tension in an assembly where some slack may be present. Their capabilities can eliminate rattle, compensate for expansion or contraction of the assembly materials, or absorb intermittent shock loads. These products are made of elastic deformable materials, most commonly convoluted ductile, high-strength metal alloys which come in machined, welded, and open-ring varieties.

  • Spring Washers - (146 companies)
    Spring washers, sometimes called disc springs, lend their mechanical capabilities to the unique profile of the material: the irregularities of the washer compress with a proportionate resistance to return to their predeflected shape. Spring washers are employed in applications where assemblies need a part to take up play, maintain assembly tension, compensate for expansion or contraction in materials, or to absorb intermittent shock loads and provide a controlled reaction under dynamic loads.
