- Single row lipped roller bearing. Fitted to the inner of the two driveside mainshaft bearings in the crankcase on all SOHC engines, both International and early Manx.
This is the original Norton fitment - lipped version in C3 (correct 'looser' fit) specification. Unfortunately this bearing is no longer being made by RHP and reluctantly we are now only able to supply this bearing from an alternative manufacturer. This bearing is supplied by NKE (a well known Austrian company) and although not of the same high reputation as original RHP bearings - they look quite reasonable, have a steel cage as per original RHP fitment and with the mileages we do on these bikes, I doubt we will ever spot the difference!
The one positive point of these bearings is - they are substantially cheaper than the equivelent RHP bearings I last purchased in 2013!
