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.
The company also produces Fey laminar sealing rings, which evolved from the piston ring for use in a variety of applications as a non-contact seal on a rotating joint, such as between a shaft and housing. They exclude grease, dirt and fluids in roller and plain bearing assemblies, whatever the temperature, according to IEC.
There are also Fuji locknuts, originally designed for retaining a bearing on a shaft. The company says that, unlike its, competitors' products, the security of the nut does not need to be supported by a tab washer or keyway, thereby reducing the total cost of installation. These nuts are used by London Underground in the refurbishment of escalators.
