Bearing Services

By using our comprehensive site service for all works in connection with structural bearings you will be assured that all installation, maintenance or renewals are completed to the manufactures full specification. This ensures that the expensive structural bearings perform to their full requisite specifications.

Our skilled site technicians have been trained by one of the worlds leading bearing manufactures to fully understand the many types of bearings that are found on all types of structures. This intensive schooling enables us to deal quickly and professionally with most site problems encountered.

Complete Site Service includes:

  • Installation: New or Replacement. Including deck lifting/lowering facilities, seating plates and plinth protection/strengthening.
  • Qualified Site Supervision: to enable your own site staff to install all types of bearings correctly – the first time.
  • Renovations or Removals of Bearings: renovations or removals of bearings from existing plinths can only be completed safely if a set sequence of procedures are carried out including deck jacking and whether it is for full bearing or part replacements. This service includes the checking of seating and the completion of plinth repairs if required.
  • Planned Bi-Annual Maintenance: To meet the manufactures minimum requirement, which helps to prevent the costly premature failure of the bearings, a qualified inspection should be undertaken to visually assess the bearings condition which will include checking the following:
    • protective paint
    • surrounding surfaces
    • checking that the wearing surfaces are continuing to operate efficiently, especially any PTFE surfaces, which must be measured and replaced if found to be below 1mm in thickness.
    • checking that the movement capacities both in rotational & translational directions have not been, nor are likely to be exceeded.
    • checking for adverse effects of external influences on fixings, bolts, seating plates.
    • Sonic Testing for metal fatigue.
