Pivot bearings: ceramic or skf
The standard set didn’t even last 12 months and due to frame design I want whatever will last the longest. I vote skf and get the best seal possible but my OH votes ceramic so when the seal does go at least the races won’t fuse solid to the balls. What do you guys think or have experience of?Posted 4 years agoslinkybikeMember
Go stainless steel or be prepared for a big bill ceramic bearings in my oppion are only good if you spend the big bucks and get the special harderend races. Otherwise the the super tough ceramic balls smash the less tough bearing race to bits. How much riding, conditions did it take to wear out a set in a year it might be good going for the design.Posted 4 years agosingletrackbikerMember
My experience of ceramic bearings hasn’t been brilliant. Foolishly bought a Superstar ceramic BB – it exploded mid ride (fitted about 6 weeks) & by the time I got home had scored the axle on the cranks. Superstar told me it was incorrectly fitted / misused. Bought a Hope Ceramic BB & bearings died fairly quickly, but nowhere near as quick as the superstar. Now run Chris King’s & they’re bombproof. I’ll stick with steel bearings from now on.Posted 4 years agoneninjaMember
Get high quality stainless steel bearings as suggested above from SKF, FAG etc
I’m not sure if he has been banished from here but kaesae formerly a member of STW does quality bearings for a decent price. He can be found on Ebay selling as Katec Bikes – username airborne10101
He supplied stainless bearings for several wheelsets. I’m yet to have to replace any of them.Posted 4 years agojimwMember
I may have got the wrong idea, but my understanding of the advantages of ceramic bearings are mostly found on applications where high rotational speed/low friction is required. As suspension bearings are only moving a fraction of a revolution, their advantages are lost. To gain the rust free advantages you would need full ceramic anyway.Posted 4 years ago
well wasn’t really a year, its a year in may and ai stripped it down maybe a month ago now…. and who knows how long they’ve been seized for. its only now riding the OHs difference I can tell the major difference in performance.
Cheers for advice guys, some good points, about the limited movement in pivot bearings especially.Posted 4 years agodeanfbmMember
I use enduro max,
fill them with extra grease carefully (remove seal least exposed)
Every 3 months split and revolve pivot bearings to work in grease and reposition ball bearings
I echo this and –

You ride 3-5 days a week and you’re bearings “only” lasted a year?
I’d say that you were lucky to have bearings last that long with that amount of riding!Posted 4 years ago
