Guide to bearing supports for buildings
Elges bearings for the building and construction sector are capable of carrying high loads, withstanding extreme temperatures and shrugging off attack by aggressive pollutants.
Most people think of buildings and bridges as rigid, immovable structures, but the truth is very different Temperature changes, wind loadings, the movement of occupants and the installation of plant and equipment - not to mention earthquakes and tremors - all cause these structures to move by small amounts

Precision bearings keep hydraulic systems running
Hydraulic drives and pumps require precision bearings and seals that are reliable, efficient and able to withstand the most demanding operating conditions.
Overview covers full linear range
Guide presents a complete overview of linear bearings and guidance systems available from precision bearings manufacturer Schaeffler UK.
To cope with this motion it is essential to design-in suitable compensation elements, such as the latest Elges spherical plain bearings from INA.
Elges bearings are developed specifically to meet the needs of the building and construction sector, capable of carrying high loads, withstanding extreme temperatures, and shrugging off attacks by aggressive pollutants, salt water, and sandstorms.
Within the range, INA offers spherical plain bearings, cylindrical bearings, bearing combinations, and rod ends incorporating spherical plain bearings.
Ideal for inaccessible locations or where low lifecycle costs are paramount, these bearings feature a maintenance-free, low-friction coating.
Elgoglide consists of a bearing surface of PTFE fabric held in a resin matrix, adhesively bonded to a steel support body.
This combination is capable of handling contact pressures of up to 300N/mm2 (dynamic) or 500N/mm2 (static).
Other properties include excellent wear resistance, low friction and the ability to run dry or unlubricated, even with reciprocating motion.
Furthermore, the bearings exhibit smooth, low-friction, low-speed running, despite extended periods of inactivity.
Residential, commercial and civic buildings can all benefit from INA's bearings, as well as rail stations, airports, bridges (both stationary and moving types), flood defence barriers, lock gates and stadia - especially those with movable roof sections.
The current vogue for buildings with cables carrying tension loads means that there is a particular demand for rod ends and other bearing elements that can provide elegant, moment-free joints.
INA has experienced engineers who can advise on particular applications, so that the optimum support bearing is specified to give high performance but at an attractive whole-life cost.
More information about INA's Elges bearings is available in the form of a new guide "Expertise in bearing support for building construction". Request a free brochure from Schaeffler (UK) ...
