8x4,2x0,2 Phosphated disc spring DIN 2093 - 5 pcs.

Disc spring 8x4,2x0,2 mm DIN 2093

A spring element with a conical profile, designed to transmit high axial forces with small deflection. The phosphated and oiled surface reduces the risk of corrosion during storage and installation.

Key parameters

• Outside diameter De: 8 mm
• Inside diameter Di: 4,2 mm
• Thickness t: 0,2 mm
• Free height l0: 0,45 mm
• Cone height h0: 0,25 mm
• Dimensional standard: DIN 2093 / DIN EN 16983
• Material: spring steel
• Finish: phosphating and oiling
• Quantity per pack: 5 pcs.

Design and application

Disc springs can be used individually or combined in series and parallel stacks to obtain the required deflection travel and force. Applications include clamping mechanisms, clutches, brakes, valves, fixtures and machine assemblies.

Deflection and force parameters from the source document

• s = 0,063 mm — F = 21 N
• s = 0,125 mm — F = 33 N
• s = 0,19 mm — F = 39 N

Selection and installation

Selection must take account of load direction, permissible deflection, stack guidance, friction and operating conditions. The drawing shows dimensional symbols and the loading method; numerical values are given in the product parameters.

The l0, h0, s and F values were transcribed from the supplied PDF document for this exact dimensional variant.

Delivery and weight

The offer includes 5 springs. The weight calculated from nominal dimensions and a steel density of 7,85 g/cm³ is approximately 0,0003 kg (1 g) for the entire pack. This is an indicative value, excluding packaging.
