Accuride® International, the leading global manufacturer of telescopic slides and sliding systems, has turned its engineering and design expertise to creating new linear friction guides with outstanding benefits for users of handling systems.
Traditional linear slides use steel or polymer ball bearings for smooth movement; friction guides use a plain bearing surface and no rolling elements. With no exposed moving parts, linear slides are ideal for harsh environments where dust, sand or any dirt particles could clog slides that use bearings. Installations are virtually maintenance-free; they have a dry movement and require no lubrication. The nature of the design and their resistance to corrosion also means that they can function in and around many types of liquids and be subjected to high-pressure washing.
Compared to equivalent recirculating ball bearing slides, these friction guides are lighter, easier to use and engineered to minimise stress and wear on the friction elements for a smooth durable operation. The quality is further evident in the low vibration and low noise operation.
The new linear bearing guides showcase all the benefits that customers have come to expect from Accuride® including ease of use, superior performance and designed-in reliability. The strong engineering pedigree has delivered a friction guide that, thanks to its extra-tough anodised aluminium track and superior polymer guide, is hardwearing and long-lasting. This longevity adds to the low total cost of ownership and also makes it an attractive alternative to applications that may be over-engineered with costlier solutions.
There are three variants in the new friction guide range; non-adjustable, manual adjust and auto-adjust with all contact surfaces engineered to produce uniform wear. The height, width and hole pitches all comply with ISO 12090-1:2011 and ISO 12090-2:2011 standards for compatibility with legacy installations.
The guides move along a hard-anodised aluminium track which is available in two standard lengths of 1 metre and 2 metres. These seamlessly fit together to permit track of any length to be designed and allows the bearing blocks to traverse freely along the whole extent of that track.The permutations of plain bearing guides and plain slides are ideally suited for many applications within machine tool, semi-conductor and materials handling markets.
