IEC will be at Northern Manufacturing & Electronics (2/3 October 2013, Event City, Manchester) to present its broad range of mechanical components for extreme operating conditions. For example, there are Schnorr disc springs (conical springs manufactured to DIN2093), which are used to interface powerful vibrating parts needing strong support and limited movement. Typical applications are in the rail industry, to absorb energy on sleeper clamps and brakes. There are also Schnorr safety washers. Available in sizes up to M36 and in a variety of materials and finishes, these conical washers provide a secure fastening on joints that are subject to high levels of vibration. Schnorr load washers (plain conical washers) are also available for high-tensile joints on bolt grades up to 12.9. These are for use where load and thermal factors are an issue.
