A wide range of bearing types are manufactured by pretread.com at our facility in Polymet Industries LLC - RAK - UAE selection of appropriate type with specification for  vertical forces  resistance  and displacements is  key responsibility of  structural designer. Clear communication for requirements of neoprene bearings and installation procedure is essential for proper functioning of structure and for avoidance of unanticipated maintenance issues and choosing correct polymer which includes neoprene and natural rubber.
Â
Types of structural – bridge and building Bearings offered.
Â
Laminated elastomeric bridge bearings
Â
Elastomeric bearings normally consist of a number of rubber layers separated by steel plates  normally molded  in pads or strips and are ideally suited for small structures to accommodate movements by deformation shear and rotations. Elastomeric bearings provide an excellent economic solution for applications where structure movements, longitudinal, transverse and rotational are small, provide vibration isolation and are generally simple to install. Neoprene rubber laminated Elastomeric bearings are relatively maintenance free but will degrade over time and require replacement.Â
Â
Plain and laminated neoprene elastomeric bearings are manufactured by pretread.com  both in neoprene and natural rubber compounds confirming to AASHTO/ BS/EN /DIN standards. Bridge bearings and bridge bearing pads are manufactured in neoprene rubber compounds,.. unless otherwise specified for natural rubber compound. Our specialization is always in neoprene compound and bridge bearings, elastomeric, pads, high damping neoprene rubber bearings are manufactured from our  years  of experience, and with support from our technical partners for all requirements of neoprene bridge bearing, neoprene bridge bearings rubber bearing, steel bearing, pot bearing, guided bearing, for all bridge and building bearing applications.
Â
Steel Pot bearings.
Â
Elastomeric steel pot bearing consists of a confined neoprene elastomeric disk  within a short cylinder (pot). Vertical load is applied through a close fitting steel ‘piston’. This puts neoprene elastomer bearing pad  under high pressure from vertical load, making it behave like a viscous liquid, meanwhile permitting rotation in any direction with very little resistance.
Â
Steel Elastomeric pot bearing with multi-directional sliding part.
Â
A sliding surface can be included to accommodate translation movement, in any direction or constrained by guides. Rotations and translations, as well as  loads carried, can be greater than for elastomeric bearings.
Â
Ptfe- Teflon sliding bearings.
Â
ptfe - TEFLON  dimpled and plain sheets are used as sliding top surface on top of laminated elastomeric bearings, Such laminated ptfeTeflon sliding bearing in combination with separate SS 316 Grade Stainless Steel mirror finished surface as sliding top plate provides excellent smooth sliding. ptfe TEFLON sheets will be to AASHTO / BS / DIN / En 1337-2 specifications. pretread.com - Polymet Industries LLC is first manufacturing facility  in Middle East United Arab Emirates to have facility to fabricate  ptfe Teflon bonding to steel and rubber, there by high cost of import and time delay can be avoided. Ptfe sliding bearings and Strips in neoprene .Ptfe Sliding bearing pads and strips are offered  for lower loads and Sliding Bearings (with laminated neoprene bearing or carbon steel backing alone) for higher loads. Both ptfe Teflon sliding, Teflon Sliding bearings as well as sliding bearing pads are supplied with appropriate thickness SS 316 mirror finished plates with mild steel backing plates for low friction coefficient ptfe pipe supports.
