SK bearings : structual bearing, buildings, bridges and anti vibration bearings

<body> <h1>SK Bearings - bridge, structural and anti-vibration bearings</h1> <p>SK Bearings is a division of the Dixon International Group Ltd. which manufactures award winning products for the construction industry, Products include : <ul> <li><strong>Sliding Bearings</strong><br> A rubber bearing allows a certain shear, which is at its maximum at around 70% of it's height. If a greater amount of shear is required then at the top or bottom of the bearing a sliding surface is formed from PTFE, which is vulcanised to the bearing assembly. When this PTFE surface is used in conjunction with a stainless steel plate or another PTFE Surface the combination yields a lower friction coefficient.<br> </li> <li><strong>Elastomeric Bearings</strong><br> <em>What is an Elastomeric Bearing ?</em><br> Elastomeric bearings or Rubber bearings are flexible points of support often used in the construction of viaducts and bridges. Rubber bearings have a wide range of uses from noise suppression (accoustic dampening), seismic bearings to special rubber mountings.<br> <br> <em>The Principle</em><br> Rubber can handle large vertical loads and depending on the design requirements our bearings can be manufactured to handle horizontal displacements and rotations.<br> <br> Horizontal Displacements - (Shear) are caused by changes in temperature of a structure, shrinkage or creep in the concrete, wind loads or brake forces transferred by vehicles to the structure.<br> <br> Rotations - can be caused by deflection of the construction<br> <br> <em>Construction of the Elastomeric Bearings</em><br> A Rubber (Elastomeric) bearing consists of rubber layers separated by vulcanized steel plates. A Rubber cover is fitted around the assembly. Natural rubber or Chloroprene rubber is used to form the layers as these offer the best resilience to temperature and growth in deformation. Chloroprene rubber is most often the material used to cover the assembled bearing, as it is highly resistant to ageing, Ozone, UV and chemical effects.<br> <br> <em>The Shape of the Bearing</em><br> When the rotation properties need to be constant in each direction on the horizontal plane a round bearing is recommended. However a rectangular bearing can handle larger rotations around its longitudinal axis when compared to the round bearing with a similar surface area.<br> </li> <li><strong>Anti Vibration Bearings</strong></li> <li><strong>Anti Vibration Pads</strong></li> </ul> <form> <input type="hidden" name="bridge, structural and anti-vibration bearings" value="bearings bridge bridges acoustic dampening anti-vibration pads pad neoprene strip point load cracks"> </form> <p><br> bearing sliding bearing rubber elastomeric structural bearings bridge bridges acoustic dampening anti-vibration pads pad neoprene strip point load cracks buildings concrete structures steel frame <br> <a HREF="http://www.skbearings.co.uk"><img SRC="logo.gif" ALT="bearing sliding bearing rubber elastomeric structural" WIDTH="1" HEIGHT="1">Anti-vibration bearings</a> </p> </body>
