Hercules Engineering Pot-Type Bearings (HPT)

Heavy Duty Bearings

Hercules Engineering Pot-Type Bearings (HPT)

Hercules Engineering Pot-Type (HPT) Bearings can be used in steel or concrete structures. They are particularly useful where large movements and multi-directional rotations need to be accommodated with a low profile, compact bearing. Separate mechanisms for rotation and translation (where applicable) provide minimum eccentricity of the load and minimum resistance to movement. High sideloads can also be accommodated simultaneously.

Standard Types

FIXED BEARINGS
The FIXED (HPT/FX) bearing consists of a steel piston fitting closely inside a steel cylinder.

EXPANSION BEARINGS
The SLIDING GUIDED and FREE-FLOAT (HPT/SG and FF) bearings are expansion bearings, similar to the fixed bearing, but with the addition of a steel slide plate faced with stainless steel, which slides on a disc of PTFE recessed into the top of the cylinder.

Design Features

Convenient Designs
Design considerations for the ease of designers, precasters & site staff.

Quality Assurance
For consistency & longevity.

Australian Adaption
Local deisgn for local conditions

Versatility/Optional Features

Standard Designs and Limitations

Vertical Load Capacity / Contact Pressure: 300kN to 30000kN
Horizontal Load Capacity: high and moderate
Coefficient of friction:
Lubricated - 0.01 (short term), 0.02 (long term)
Unlubricated - 0.03 (full load), 0.05 (half load)
Expansion Capability: (movement) ±50mm in the principal direction, ±20mm in the transverse direction
Rotation Capacity: 0.030 to 0.015 rads
Eccentricity of Vertical Load: less than A/50
Full Work Load: 0.5 to 2.0mm
Maximum Operating Temperature: 90°C

Classification by series

Seires A bearings provide for HIGH sideload.
Series B bearings provide for lesser sideloads, with the additional feature of INTERCHANGEABILITY between some bearing types.
Series C bearings are CUSTOM-DESIGNED for any non-standard parameter or special application.

Attachment Alternatives

Several options are available:
1.The Zero option (i.e. no positive attachment - anchorage by friction alone)
2. Cast-in Sockets
3. Attachment Plates with cast-in dowels (as per the following tables)
4. Attachment Plates with cast-in hold-down bolts, (bottom plates in particular)
5. Tapped holes in the top and bottom plates of the bearings (usually reserved for steel construction)
