SK Bearings is quality assured to ISO 9002.

Our products are manufactured to the following British Standards:

If you have any questions not answered here, our technical department will be pleased to assist. Alternatively, a link to the British Standards Institute website is provided on the links page.

Testing Facilities
SK Bearings have test facilities to Grade A Standard and a test press with a National Physical Laboratory calibration certificate. It is capable of imposing vertical loads of up to 5,000 kN combined with horizontal loads of up to 250 kN. Hence, it is possible to conduct full scale tests on complete bearings to the required standard.

Our Quality Control Laboratory is fully equipped with the latest equipment, enabling our technical staff to check products at each stage of the manufacturing process and maintain a high standard. Certificates and letters of conformity are available for our products if required.

We have the facilities to test for example, shear resistance, tensile strength, degrees hardness IRHD, and ozone or UV light degradation.

Our new fire protection for bearings was developed using a full-sized, gas-fired furnace on site, capable of indicative tests using the BS 476 time-temperature curve. We invest substantially to ensure that we maintain the highest standards in testing, research and quality control. We can offer the sort of expertise which is only available from one of the UK's most innovative companies (as we were recently described by the Design Council).

A concentration on quality and knowledge places us in a particularly strong position to help clients by developing novel or bespoke solutions for unusual applications - or simply providing the facilities to carry out tests. For further information, our technical department will be pleased to assist.

Specifier's Checklist
Recognising the difference between a bearing that will do its job safely and reliably over the life-span of a building and one which does not can make a very significant difference - by avoiding the expense of remedial work and in some cases, legal proceedings.

Superficially, a perfectly good bearing may look no different from one which will fail in service. So here, we provide a brief guide to ensuring that the bearings selected will perform as intended.

  1. Has the elastomeric compound been formulated specifically for use as a structural or bridge bearing?
  2. Are there any flaws in the bond between elastomer and steel reinforcement plate (or PTFE surface)?
  3. Are components chemically bonded under heat and pressure?
  4. Has the moulding process resulted in an even cure?
  5. Do the materials meet or exceed British Standards?
  6. Does the manufacturer apply rigorous standards to materials, manufacture and quality control?
  7. Does the manufacturer offer customers the choice of seeing the products tested before they leave the factory?
  8. Does the manufacturer offer to check the products are suitable for the purpose specified, without charge?
  9. Does the manufacturer provide free technical and field support?
At SK Bearings we have always believed that cutting corners on structural and bridge bearings is a false economy. The idea is not a new one - as Shakespeare noted in the Merchant of Venice, 'The sweetness of low price is long outlasted by the bitterness of poor quality'.

This is why SK Bearings is philosophically committed to the highest standards in computerised design, selecting materials, manufacturing, technical expertise and quality control. SK Bearings come with reliability and quality built-in.
