Herculon Type D Tank Top Bearings (HLD/TT)
Type 'D' Steel Bearings
Herculon Type D Tank Top Bearings (HLD/TT)
Herculon Type D Tank Top (HLD/TT) Bearings have been developed to fulfil the need for an easily installed low friction bearing under roof beams of water tanks. They are particularly useful where loads are small and both lateral and uplift forces need to be accommodated. They can also be used in other light structures.
Materials
Consists of a thin stainless steel slide plate with two stainless steel studs flash welded to the upper face. The lower face is highly polished and the plate is provided with two slotted holes for uplift through-bolts. This plate slides against a Hercuflon coated Hercupad which has two clearance holes drilled in it.
Types
Only one type of HLD/TT bearing available but it is available in five sizes depending upon working load requirements (see Table 3-10).
Design
• Coefficient of friction: 0.05 - 0.08 depending on stress)
• Expansion capacity: up to ±20 mm
• Maximum rotation: up to 0.01 radians
• Maximum temperature: 80°C
Installation
HLD/TT bearing installed on a steel or concrete water tank.

Ordering
Table 3-10 details the range of sizes available and Fig 3-19 provides the dimension reference points reflected in the table. These bearings are designed to fit standard UNIVERSAL BEAMS. The standard designs incorporate M20 bolts which should be adequate for most applications.
