sealed bearings on drive shaft and hub
Posted: Sun Apr 30, 2017 5:39 pm
has any one tried sealed bearings on drive shaft and hub assembly?
lubrication for both pairs appears hit and miss , with oil lube blessed with shards of gear tooth with open bearings,
have you been fitting c3 grade bearings in this application , c3 give more clearance for hot running? do not know whether or jap bikes don't just run std clearance in a worse application ie more power
you could get 3 off 6004 20x42x12 bearings in the tailpiece or 2 off 63004 2RS 20x42x16 and a shortened spacer and an oilseal bracing it up a good amount with less load than failing 6004 or the 8mm wide ones 1604 type
Same choice for 17*42*12 rear hub, 2off SKF 6203 C3 bearings sealed or open bearings
many motor bikes use sealed bearings in these sizes for the wheel spindles with higher performance so should be fine
