Even pillow block bearings are getting environmental

<p style="text-align: center;"><img src="/ueditor/php/upload/image/20220329/1648538208104266.jpg" title="1648538208104266.jpg" alt="5.jpg"/></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">Biomimicry has long been a great shortcut for designers looking for strong, creative designs. The new igubal pillow block from igus is based on the design principles of a tree and provides an alternative to classic cast iron housings.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">Flattened radii ensure maximum resistance to mechanical stresses. The bionic shaped housings, made with high-performance materials from the international leader in the motion plastics industry, require no lubrication or maintenance.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">Cast housing bearings with metal ball bearings quickly reach their limits in dusty, wet, and dirty environments. Whether in pulleys on conveyor belts in a cement factory or in tipping devices on trailers in the field, they are prone to failure. A high degree of contamination and inadequate lubrication are responsible for 80% of premature bearing failures. There is also the constant risk of corrosion.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">Lubrication-free bearing inserts made of high-performance plastic solve the problem. igubal polymer pillow blocks in the standard sizes of 20, 25, and 30 mm enable quick one-to-one replacement. Two-hole and four-hole flange bearings in the sizes of 20, 30, and 40 mm are also available.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">Engineers at igus use two strategies to ensure that the plastic pillow blocks are sufficiently robust in industrial applications. The first is working with fibers and fillers that reinforce the igubal plastic so that it withstands high surface pressure and edge loads even under continuous stress. The second follows a model from nature: the so-called tree crotch, a connection found between branches and trunk or where the tree is firmly anchored in the ground. The shape is considered particularly efficient and robust.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">The designers have optimized the shape of the housing notches and done away with constant radii in order to distribute the stress more evenly. This makes igubal housing bearings highly resilient. Their chemical resistance, freedom from corrosion, and insensitivity to dirt give the bearing inserts a significantly longer service life in numerous customer applications over metallic bearings.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">The absence of lubricants also reduces maintenance and cleaning requirements and enhances environmental protection. There are no lubricants at any point in the system that could get into the environment or on to the product.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px;">The new <a href="http://www.dacbearing.com/products/Pillow-Block-Bearing/135.html" target="_blank" style="color: rgb(0, 112, 192); text-decoration: underline;"><span style="font-family: arial, helvetica, sans-serif; font-size: 16px; color: rgb(0, 112, 192);"><strong>pillow blocks bearings</strong></span></a> are not the only products igus is adding to the igubal range. There are also three bearing inserts for the imperial market, now available in 1-, 1.5-, and 2-in. inside diameter sizes. The price for FDA-compliant iglide A350 plain bearings will also be reduced by roughly 50% in the future. This is because igus no longer manufactures the bearing exclusively by turning bar stock — but has recently added the more cost-effective injection molding process.</span></p><p><br/></p>
