DIN128B Wave Spring Lock Washers

DIN 128B Wave Spring Lock Washers are used in bolted connections where a constant spring effect is required to maintain pressure between assembled components. The curved washer profile allows controlled deflection under load, making it suitable for compensating for dimensional variations, reducing the influence of vibration, and maintaining a stable preload in mechanical assemblies.

Compared with conventional flat washers, DIN 128B washers provide additional axial flexibility through their wave-shaped design. They are available in spring steel for applications requiring high elastic performance and stainless steel A2/A4 for corrosive environments. With different diameters and thickness options, these curved spring washers are widely applied in gearboxes, motors, pumps, valves, electrical equipment, and precision machinery requiring reliable spring compensation.

Specification:

The specification of DIN 128B Wave Spring Lock Washers covers the dimensional requirements, material options, and manufacturing details required for different assembly conditions. Key specifications include inside diameter, outside diameter, washer thickness, free height, number of waves, material grade, and surface finish, which determine the spring performance and installation compatibility.

DIN 128B curved spring washers are available in different diameters and thicknesses according to application requirements. Spring steel is commonly selected for applications requiring higher elasticity and load capacity, while stainless steel A2 and A4 options are suitable for environments requiring improved corrosion resistance. Surface treatments such as zinc plating, black oxide, and customized coatings can be supplied to meet different operating conditions.

Dimension Chart of DIN128B Wave Spring Lock Washers:

The dimension chart of DIN 128B Wave Spring Lock Washers provides the key measurements required to select the correct washer according to bolt size, installation space, and required spring deflection. The chart includes important dimensions such as inside diameter, outside diameter, thickness, free height, and wave profile dimensions that affect the washer’s elastic performance after compression. When selecting DIN 128B curved spring washers, the inside diameter should match the corresponding bolt diameter, while the thickness and free height determine the available spring travel and load characteristics. Different diameter and thickness combinations allow these washers to be used in assemblies requiring compensation for tolerances, thermal expansion, or minor component movement.
