SKF 441933E Equivalent Wheel Bearings for the
RS200 and the Metro 6R4 and others

At HB Bearings we continue to manufacture and keep in stock an equivalent bearing for the SKF 441933E wheel bearing which was originally fitted to these cars. This bearing is also found in a number of other vehicles. This is a quality bearing made to the original manufacturers specification. The bearing has been upgraded by HB to include a machined bronze cage and is available ex-stock.

RS200/Metro 6R4 wheel bearing


RS200/Metro 6R4 wheel bearing

HB Bearings, keeping Group B rally cars running.

The MG Metro 6R4 Group B rally car, and the Ford RS200 were both outstanding rally cars of the 1980ís and remaining examples are keenly collected today. As with many historic cars even of this late age, finding replacement parts is becoming increasingly difficult. Wheel bearings are a typical example where existing stocks are drying up or have become obsolete altogether.

Both cars were originally fitted with a SKF bearing reference 449133E. This bearing has long since been out of production and is hard to obtain. However, at HB Bearings a replacement (ref, HB103693) has been available, ex-stock for some time. Whilst the bearings from each of the companies may seem identical when viewed side by side there the similarity ends.

The quality of bearing steel has come a long way since the 70ís when the original bearings were first manufactured and much cleaner steels are employed in the HB version. In addition, the nylon cage has been replaced with a much stronger one piece machined bronze cage. The bearing races benefit from being manufactured on highly accurate Swiss CNC grinding machines.

With Quality Control inspection on a CNC coordinate measuring machine, each bearing is checked for accuracy when completed. This is just one example of the many types of bearing HB keep in stock for historic cars. Bearings are also stocked for historic motorcycles both British and Japanese. Overview HBís bearings are used at the highest levels of motorsport such as F1, MOTOGP, Touring and WRC. These bearings are designed to deal with high levels of performance and can contain many special features.

An example of this is the special bearing made for Padgetts Racing Teamís 1993 classic Honda. Winner of the 2016 Isle of Man Classic 250cc TT. Bespoke bearing designs can incorporate non-standard sizes, clamping flanges, anti-rotation holes, ceramic rolling elements, and material upgrades. With manufacture in the UK, HB can offer low volumes and short lead times.
