When your project demands superior movement control under heavy loads, the Hercules sliding bearing provides an engineered solution you can trust. Hercules Structural Systems developed the HLD and HLMD types to manage thermal expansion, material creep, and other dynamic forces effectively. They are a critical component for modern construction, preventing stress build-up that could compromise structural integrity. We designed these bearings to provide low-friction support for elements like corbels, columns, beams, and slabs.
HLD Type – The Versatile Low-Friction Sliding Bearing
We developed the HERCULES TYPE D (HLD) bearing to provide dependable, low-friction support in a wide range of applications. Instead of a continuous slip joint, you can install these compact units directly under beams, slabs, and other structural members. Its durable materials handle significant static and dynamic loads, ensuring reliable performance. Consequently, the HLD bearing is a preferred choice for standard building projects, small-span bridges, and support for industrial equipment like pipes, ducts, and conveyors.
HLMD Type – The High-Load, Low-Friction Solution
For even more demanding, high-stress environments, we engineered the HERCULES MODIFIED TYPE D (HLMD) bearing. This model enhances the proven design of the HLD series to support highly stressed structural elements. Its primary advantage is its ability to maintain low-friction properties under immense pressure. Furthermore, this makes it the ideal choice for heavy-duty infrastructure, including cast-in-situ concrete and post-tensioned slabs and beams where precise movement control is paramount.
Choosing the Right Hercules Sliding Bearing: HLD vs. HLMD
Selecting the correct bearing is crucial for your project’s success.
-
- The HLD sliding bearing is the versatile workhorse, perfect for a broad scope of projects with standard to heavy load requirements. It offers a cost-effective and easy-to-install solution.
- In contrast, the HLMD high load bearing excels under the immense pressure found in large-scale infrastructure. Choose the HLMD when your project involves post-tensioning or other conditions that introduce exceptionally high stress on the support points.
For structures that also require significant rotational capacity, such as complex interchanges or curved bridges, consider pairing these with our Hercules Pot Bearings.
Applications Across Industries
The versatility and reliability of the Hercules sliding bearing make it indispensable in numerous sectors.
-
- Bridge Construction: In small to medium-span bridges, these bearings accommodate thermal movement without the need for complex joint systems.
- Building and Commercial Projects: Engineers use them under beams and slabs in high-rise buildings and large commercial centers to manage structural loads safely.
- Industrial Systems: They provide critical support for heavy machinery, pressure vessels, and conveyor systems that experience variable loads and movement.
