- Single row roller bearing.from top quality RHP or SKF brand. As fitted to the drive side (i.e. brake drum side) on the magnesium conical rear hubs of the type fitted to 1950 Gardengate and later DOHC Featherbed Manx Nortons. 

This is now a very difficult bearing to obtain from the original high quality manufacturers - they have been obsolete for some time.

This listing is for the roller bearing which was fitted on the drive/brake side, as per photo.   This type of hub was fitted with a single ball bearing on the plain side and a roller bearing on the brake drum side - but the bearing is now obsolete and very difficult to obtain.  In the photo you will see the box was RHP and was old stock - as it is supplied in the older style RHP bearing (not unusual for bearing suppliers to sometimes supply them in the older boxes, or just rebox them if the boxes get tatty).  We ask our bearing suppliers to try and source these for us - and sometimes they come in original boxes, or if too tatty they will re-box for us . . . but rest assured, the bearing inside will still be new and in a sealed packet.

Although RHP brand are shown, we also get those manufactured by SKF - and if so, ths will be marked on the box.  However - both brands are top bearing manufacturers and the bearings are of the best quality attainable.

The price shown is based on these now being unobtainable, and we also having to pay a very high price to obtain them, and being a top branded UK sourced bearing.  Once current stock has gone, we may not be able to attain them again - and the price will certainly rise further


Final point:  You may notice in the photo that the conical hub is fitted into a 1950 Gardengate frame - this conical hub was only fitted into that frame for the last year of the Gardengate year - 1950, after that the same hub was fitted into the Featherbed DOHC Manx Norton.  The normal Gardengate rear spindle (just visible in photo) was a special affair with a large diameter flat section in the middle.  The 1950 Norton Spare Parts List shows that special plunger rear spindle still being fitted to this type of conical hub - but I have been unable to find bearings to fit this setup.  Instead, this bearing is the type fitted to later DOHC Featherbed conical hubs - where there was an alloy spacer between the bearings, and a parallel spindle that pushed through the alloy spacer.  This bearing distance piece is shown in the second photo.

Therefore - bear in mind if ordering these bearings - the inner diameter of this bearing is 7/8" - to fit onto that type of alloy spacer, it will not fit onto the original Gardengate plunger spindle which is a lesser diameter at the bearing location point
