TechStar™ Bridge Bearing Systems
TechStar™ Inc manufacture a wide range of bridge bearing systems to cater for all size bridges and viaducts. Their bearings can be found on many high profile bridges throughout the world having supplied in excess of 30,000 bearings to the world market! The various types of bridge bearings include, Pot Bearings, Elastomeric Laminated Bearings, Disc Bearings and Spherical Bearings.
TechStar™ Pot Bearings
|
The advanced design of TechStar™ Pot Bearings is based on the latest developments in bearing engineering and is accomplished with the help of finite element analysis. TechStar™ Pot Bearings can be designed in accordance with AASHTO Allowable Stress Design, Load Reduction Factor Design (LRFD), BS 5400, DIN standards, or to the Japanese Code (JIS). The detailing of the shop drawings for TechStar™ Bearings is performed on a modern Computer Aided Drawing (CAD) system that enables the adaptation of Bearings to fit almost any combination of loads, movements, and rotations. Special dimensional conditions can also be satisfied.

TechStar™ Laminated Elastomeric Bearings
|
TechStar™ supplies many types of bearings to many regions and climates throughout the world. One type, elastomeric laminated bridge bearings (TEB), continue to provide excellent service and quality, proving invariably their efficiency and durability. TEBs have advantages over alternative metallic mechanical bearings, being easier to install, effective in corrosive environments and requiring no maintenance. These advantages are quantifiable in the economics of bridge building.

TechStar™ Disc Bearings
|
The TechStar™ ‘Disc Bearing’ solution offers a lower profile (vertical height) than typical Pot Bearings. Even with the lower profile, Disc Bearings can provide the same load capacity and movement as Pot Bearings provide. Another advantage that Disc Bearings has over Pot Bearings, is not relying on rubber seals to retain the elastomer, therefore offering the potential for greater service life. In the United States and all over the world, Bridge Builders are using Disc Bearings more and more. TechStar™ disc bearings can be found in the States of Arizona, Florida, Illinois, Louisiana, New York, Ohio, Oregon, and Rhode Island. They can also be found in countries such as Qatar, Bangkok and India. TechStar™ manufactures Disc Bearings in their facilities in the USA, Canada, Taiwan, Thailand, China and India.

TechStar™ Spherical Bearings
|
Spherical Bearings are designed for very high vertical, horizontal and lateral loads and where large rotational structural displacements need to be accommodated. The bearings are grouped into three categories: fixed bearing (restriction of all movement in planar axis); guided bearing (restriction of movement in one direction in planar axis); multi-directional bearing (allows movement in all planes and axes). All three types can be designed to accommodate uplift loads, often required during construction or during the life of the structure. The bearings are designed to be quickly and easily replaced because of the structural fastening and attachment strategy TechStar™ deploys. Structural rotation is accommodated by a system of convex and concave plates which are, in turn, mounted onto a flat sliding surface which allows horizontal displacements whilst the curved bearings rotate about their center of radius.
