DISCovering High Load Structural Bearings
Accommodating large multi-directional rotations and long-term maintenance
You may find your longer span, complex bridge structures have higher needs for accommodating structural movements. This can be answered with high load multi-rotational (HLMR) disc bearing assemblies.

Understanding HLMR disc bearing assemblies involves starting with where and why they are used. HLMR bearing assemblies transmit forces while accommodating structural movements. The selection of an appropriate bearing assembly is based on the magnitude of vertical and horizontal forces, as well as the amount of displacement and rotation of the superstructure elements. Based on these requirements, your D.S. Brown team can prepare a custom designed solution.


So, what are HLMR disc bearings?

Tired at Work?
From ConstructionPros.com : 69% of construction workers say they are tired at work. A new 20-page report issued by the National Safety Council (NSC) on Oct. 1 stated that 69 percent of workers it polled across the construction, manufacturing, transportation and utility industries said they are “tired at work,” which the group said, “increases the risk of injuries and incidents on the job.” On top of that, transportation industry employees who reported at least one risk factor for fatigue cited long shifts (42 percent) and sleep loss (48 percent) as the “most common cause” of their fatigue.

Versiflex™ HLMR Disc Bearing Assemblies
Versiflex™ HLMR disc bearing assemblies consist of an elastomeric disc made of unconfined polyether-urethane polymer to accommodate rotation between two metal plates. The vertical loads are transferred by the elastomeric disc. Horizontal shear forces are transmitted between upper and lower plates by a dowel pin mechanism in the center of the bearing.

The advantages include that Versiflex HLMR disc bearing assemblies are multi-rotational, lower profile (vertical height) and cost efficient.
