Granor RJWatson Disk Bearings - Series "DSK"
Granor is a licensed manufacturer of RJWatson Disk Bearings. Used since the 1970's, disk bearings in the United States are progressively extending their dominance over more dated pot bearing technology. By ordering from Granor there are the benefits of local manufacture combined with access to current generation technology.
Applications
Disk bearings can be used with bridges, within multistory buildings, or with any other structures requiring low moment transfer supports. Disk bearings come in three fixity configurations - fixed, guided and free-float. Disk bearings can be manufactured to support a few hundred kN's right up to tens of thousands of kN's.
Fail Safe
Disk bearings replace the confined pot/piston arrangement, used in pot bearings, with a high strength polymer disk. Without the need to rely, for many years, on precision geometry to prevent elastomer extrusion and bearing failure, disk bearings offer an advantage in terms of risk management. If you consider the cost of shutting down a bridge jacking it up and replacing failed bearings, it is logical to use a failsafe design wherever possible.
Horizontal Loads
Because of the design, disk bearings are excellent at handling very high horizontal loads.
Low Profile
Disk bearings often have a lower height than pot bearings designed for equivalent loads.
Rotational Stiffness
Disk bearings offer low rotational stiffness values similar to those of pot bearings. Experimentation indicates in some cases disk bearings have lower rotational stiffness than pot bearings, and in all cases a similar low order of magnitude.
Economical
Granor RJWatson Disk Bearings have a simpler more efficient design than earlier technologies. This optimisation yields production savings which are passed on and can contribute to competitive advantage in tender environments.
Short Lead Times
Because of the more efficient design, Granor can manufacture disk bearings more rapidly than similar bearings of other types.
