Products

Our fabulous range of products include:

Hercuslip™ Composite Slipjoint. 
A reliable, easily applied slipjoint material on load bearing brickwork and under concrete slabs. It is specifically designed to centralise loads and accommodate initial shrinkage and subsequent thermal movement. Ideal for post-tensioned and cast in-situ slabs.

Hercules™ Shearstrip. 
This is a reliable, economical bearing strip under short span cast concrete slabs. Designed to centralise loads and accommodate very small movements.

Herculon™ Modified Type “B” and Type “D” Bearing 
These bearings have been developed to fulfil the need for a simple, low friction bearing on corbels and columns where a continuous slipjoint is inappropriate. They can be cast in-situ and also in post-tensioned slabs and beams. Type “D” is used where a highly stressed bearing is required.

Hercuslip Composite

Hercuslip Composite

Application
Hercuslip Composite (HSC) has been developed to fill the need for a reliable, easily applied slipjoint material on load bearing brickwork and under concrete slabs. It is specifically designed to centralise loads and accommodate initial shrinkage and subsequent thermal movement. It is ideal for post-tensioned and cast in-situ slabs.

Materials
HSC consists of a stainless steel sheet sliding against a Hercuflon coated natural rubber strip, blocked out either side with polystyrene spacer strips.

Hercules Shearstrip

Hercules Shearstrip

Application
Hercules Shearstrip (HSS) has been developed to fill the need for a reliable, economical bearing strip under short span cast concrete slabs. It is designed to centralise loads and accomodate very small movements.

Materials
HSS consists of a natural rubber strip blocked out either side with expanded polystyrene spacer strips taped top and bottom with adhesive tape.

Herculon Type D Free Float Bearings

Herculon Type D Free Float Bearings

Application
Herculon Type D Free Float Bearings (HLD/FF) have been developed to fulfil the need for a low friction bearing on corbels and columns where a continuous slipjoint is inappropriate. They can be used under beams and slabs and also under pipes, ducts, conveyors, pressure vessels and small span bridges.

Materials
HLD/FF consist of a mild steel top plate to which is attached a polished stainless steel facing plate. This plate slides against a Hercuflon coated Hercupad which in turn is bonded to a mild steel base plate (optional).

Design
The following design limitations are recommended:

• Coefficient of friction 0.05 – 0.08 depending on stress.
• Expansion capacity up to ±30 mm.
• Maximum contact stress 10 MPa.
• Maximum rotation up to 0.02 radians.
• Maximum temperature 80°C.

Standard top slide plates have been designed to accomodate up to ±30 mm design expansion in the principle direction of movement and ±7.5 mm in transverse direction. If extra expansion or rotation capacity is required please contact our Technical Department.

Herculon Type D Fixed (HLD/FX) Bearings

Herculon Type D Fixed (HLD/FX) Bearings

Herculon Type D Fixed (HLD/FX) Bearings  have been developed to fulfil the need for a rotation only bearing on corbels and columns. They can be used under beams and slabs and also under pipes, ducts, conveyors, pressure vessels and small span bridges. These bearings are designed to be removable and to accept a lateral load of 30% of the vertical rated load.

Materials
The HLD/FX bearing consists of a mild steel top plate bonded to a fixed Hercupad, which in turn is bonded to a mild steel base plate. Two shear pins are provided to transfer the lateral loads.

Design

The following design limitations are recommended:

• Maximum contact stress 10 MPa.
• Maximum rotation up to 0.02 radians.
• Maximum temperature 80°C.

Herculon Type D Sliding Guided (HLD/SG) Bearings

Herculon Type D Sliding Guided (HLD/SG) Bearings

Herculon Type D Sliding Guided (HLD/SG) Bearings have been developed to fulfil the need for a low friction bearing on corbels and columns where a continuous slipjoint is inappropriate. They can be used under beams and slabs and also under pipes, ducts, conveyors, pressure vessels and small span bridges. These bearings are designed to be removable and to accept a lateral load of 30% of the vertical rated load.

Materials

HLD/SG bearing consists of a mild steel top plate to which is welded a polished stainless steel facing plate. This plate slides against a Hercuflon coated Hercupad. This in turn is bonded to a mild steel base plate.

Design
The following design limitations are recommended:

• Coefficient of friction 0.05 – 0.08 depending on stress.
• Expansion capacity up to ±40 mm.
• Maximum contact stress 10 MPa.
• Maximum rotation up to 0.02 radians.
• Maximum temperature 80°C.

Herculon Type D Tank Top Bearings

Herculon Type D Tank Top Bearings

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
The HLD/TT bearing 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

There is only one type of HLD/TT bearing available but it is available in five sizes depending upon working load requirements (see Table 3-10). Bearings having larger
capacities or of different dimensions than those listed can be designed by our Technical Department.

Design
The following design limitations are recommended:

• 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.

Herculon™ Modified Type “D” Bearing

Herculon™ Modified Type “D” Bearing

Herculon™ Modified  Type “D” Bearing

Application
Herculon Modified Type D (HLMD) Bearings (see Fig 2-4) have been developed to fulfil the need for a simple, low friction, highly stressed bearing on corbels and columns where a continuous slipjoint is inappropriate. They can be used under cast in-situ and posttensioned slabs and beams.

Materials
HLMD bearings consist of a stainless steel top plate roughened on the upper surface andpolished on the lower. This steel plate slides against a Hercuflon coated Hercupad.

Types
There are two basic types of HLMD bearings available:

• Standard, and
• Seismic.

The seismic bearings are manufactured from the same materials as the standard bearings but they have greater all round expansion capacity (±50 mm) to accommodate the larger movements which occur during seismic shock.

Design
The following design limitations are recommended:

• Coefficient of friction 0.05.
• Expansion capacity up to ±20 mm (standard), up to ±50 mm all round (seismic).
• Maximum contact stress 10 MPa.
• Maximum temperature 80°C.
• Maximum rotation up to 0.02 radians

Herculon™ Modified Type “B” Bearing

Herculon™ Modified Type “B” Bearing

Application
Herculon Modified Type B (HLMB) Bearings (see Fig 2-1) have been developed to fulfil the need for a simple, low friction bearing on corbels and columns where a continuous
slipjoint is inappropriate. They can be used under cast in-situ and post-tensioned slabs and beams.

Materials
HLMB bearings consist of a stainless steel top plate roughened on the upper surface and polished on the lower. This plate slides against a Hercuflon coated natural rubber pad that is bordered by polystyrene strips.

Types

There are two basic types of HLMB bearing available:

• Standard, and
• Seismic

The seismic bearings are manufactured from the same materials as the standard bearings but they have greater all round expansion capacity (±50 mm) to accommodate the larger movements which occur during seismic shock.
