Parker-Origa is introducing a means of protection that can be applied to its complete range of linear drives; it is even claimed to be suitable for preventing problems that might be caused by sugary or sticky fluids present in food manufacturing and other process lines. The new Clean Design system protects linear drives – including associated guides, sensors and position sensing systems – in a modular, stainless steel housing that is sealed to IP64. The resulting drive is suitable for use where intensive washdowns are frequent, as well as in damp, dusty and otherwise challenging environments.
Key to the effectiveness of the Clean Design system is the specially designed longitudinal seal. A driven element passing through the seal provides the connection between the linear drive and the customer's equipment. The design and layout of the seal is such that fluids run off the outer lip of the seal and do not penetrate inside. The lips of the seal are made from low-wear material and, if necessary, can be changed very simply without the need for tools.
Attention has also been paid to ease of access and maintenance for the drive itself. The upward-facing cover plate of the Clean Design is easily released and removed by simply undoing a few screws.
Parker-Origa's Clean Design linear drive and its driven element can be installed laterally or vertically without compromising the protection provided by the seal. Depending on the stroke of the linear drive, a number of assembly fixing points are provided, either directly on the threaded holes of the fixing points or by using adaptors. The air connection needs only to be made at the front end, which makes installation in confined spaces easier.
