Nolan Whitleyon Losi 5x10x4mm Heavy Duty Clutch Bearing (2)

I agree with the previous review. Unfortunately Losi missed the mark with these "Clutch Bearings". I shimmed the Clutch perfectly and these still blew apart in about 2 qualifiers (7 mins). I don't believe that these are actually designed for clutches. I would suggest going with JT bearings or something else that is proven. Stay away from these.

These are also used in the front wheel hubs of the XXX-SCB and XXX-SCT.

Ordered a pair of those bearings and they lasted for about one hour before one of them lost at least one of its shields! Didn't check the other one.

What reviewers say

Three reviews give a split picture of this 5x10x4mm heavy duty bearing pair. Two reviewers rated it 1/5, reporting that the bearings failed quickly, one after about two qualifiers and the other after roughly one hour, with a shield lost on one bearing. One of these reviewers suggested the bearings may not be suited to clutch use and recommended alternatives. A third reviewer rated it 5/5 and noted that the same bearing size is used in the front wheel hubs of certain Losi XXX-SCB and XXX-SCT models. No reviewer reports on the bearing's performance in that hub application. The sample is small and the reviews conflict, so the overall picture is limited.

  • + Used in XXX-SCB and XXX-SCT front hubs, per one reviewer
  • − Failed quickly in clutch use, per two reviewers
  • − Shield lost on one bearing after about one hour
