Herculon Type D Free Float Bearings (HLD/FF)
Type 'D' Steel Bearings
Herculon Type D Free Float Bearings (HLD/FF)
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 accommodate up to ±30mm 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.
