• bearings should be handled with care and stored under cover, in clean conditions. they are supplied in roll and pad form, ready to lay - so none of the waterproof paper, expanded polystyrene etc. should be removed (unless specifically advised by SK Bearings).

• all surfaces onto which bearings are to be laid should be clean, smooth and free from sharp projections.

 laying

• strips of SKS or SKL should be laid in one continuous operation with the waterproof paper backing uppermost on the surface of the supporting wall, having checked their location and orientation.
• SKS pads should also be laid on the supporting area with the waterproof paper on top and in the correct orientation.
• bearings supplied with expanded polystyrene surrounding the strip or pads should completely cover the supporting surface (usually with the strip or pads located centrally).
• IT IS VITAL TO ENSURE THE GAP BETWEEN SUPPORTING SURFACES IS NOT BRIDGED BY PLASTER, GROUT ETC. SINCE THIS WOULD PREVENT THE BEARING FROM FUNCTIONING.
• it is not generally necessary to fix SKS or SKL in place since the friction between the rubber and the support surfaces is usually sufficient. where there is insufficient friction (for instance, in cases where a low vertical load is combined with large movements) we recommend that a non solvent-based adhesive is used. solvent-based adhesives should be avoided because they may damage the components as well as being harmful to people and the environment.
• bearings must not be subjected to excessive loads, even for short periods. when setting levels, do not apply uneven loads or hammer blows to any bearings.
• never install a damaged bearing.
• never allow foreign matter to enter the working parts of a bearing. the working surfaces should be protected during the pouring of in situ concrete.
• any threaded fixings must be tightened uniformly and without excessive force.
• any concrete which overlaps a joint must be cut away to ensure the bearings' flexibility is not jeopardised.
