service is available for bearings of up to 1,500mm OD including deep groove and angular contact ball bearings, cylindrical roller, thrust and split roller bearings. Thanks to a recent investment of nearly £1m in new CNC grinding machines the lead time for large sized bearings has been reduced to as little as 18 weeks, a dramatic cut compared to the industry average of 18+ months.
At the best of times a large bearing failure is a costly problem to solve; this is especially true when the bearing type is no longer manufactured and re-engineering is necessary to accommodate a more readily available replacement. In today’s cost-down, efficiency driven environment these costs can prove to be prohibitive, especially when production disruption costs are taken into consideration. Fortunately Revolvo is able to manufacture replacement bearings that meet or even exceed the original design and performance envelope of virtually all existing and obsolete bearing designs that fall within their core product range.
“Our ability to provide replacements for obsolete bearings across the size range, including – crucially - larger sizes up to 1500mm outside diameter, in relatively short delivery times, means that we can often provide a solution in heavily capitalised continuous process industries which are faced with potentially crippling costs as a result of bearing-related equipment failure,” said Adrian Menzies, Revolvo’s Sales and Marketing Director.
Revolvo manufactures many types of bearings which have been made obsolete by the original manufacturer. These bearings are manufactured either from original drawings, or from drawings that Revolvo produces by reverse engineering samples of obsolete bearings provided by the customer. In addition, the company carries out refurbishment work on larger sized bearings both solid and split, where it is economically viable as an alternative to manufacturing new products.
Replacement bearings manufactured by Revolvo can be either Metric or Imperial variants; they can be tailor-made equivalents of obsolete bearings, or be subtly modified through improvements that overcome problems of reduced running life due to factors such as inadequate load capacity, sealing and poor lubrication. In all cases the quality of the product is underwritten by Revolvo’s ISO accreditation, and bearings are manufactured to DIN PO/ABEC 1 standards, with up to P5 available on request.
Revolvo’s ability to provide replacements for obsolete bearings and specialised bearing types is underpinned by its status as a core competence centre for bearing manufacturing within a large international engineering group. The recent investment in manufacturing capacity, its own technical support service, and access to a global distribution infrastructure ensures customers receive both bearings and service of the highest quality.
