12x4,2x0,5 Phosphated disc spring DIN 2093 - 1000 pcs.

Disc spring 12x4,2x0,5 mm DIN 2093

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

Design and application

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

Deflection and force data from the source document

• s = 0,088 mm — F = 116 N
• s = 0,175 mm — F = 208 N
• s = 0,26 mm — F = 284 N

Selection and installation

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

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

The source document identifies this variant as a size not included in the standard table.

Delivery and weight

The offer includes 1000 springs. The weight calculated from nominal dimensions and a steel density of 7,85 g/cm³ is approximately 0,39 kg (390 g) for the entire pack. This is an indicative value, excluding packaging.
