The xxx-sct takes 5x10 bearings in the front, that's why they do not fit. Not the bearings fault, it is yours. So why rate the bearing? These bearings are great, at a $1 a piece, they are a steal

these protek bearings are all I use as a replacement for the stock bearings when they blow out. great quality and a good idea to keep as spares.

Ordered these bearings. They are too small for xxx-sct wheels.

What reviewers say

Reviewers generally rate these rubber sealed 3/16 x 3/8 x 1/8 inch bearings favourably, with praise for quality and value at about $1 each, and one reviewer describing them as a good spare to keep on hand. The main point of disagreement is fit: one reviewer reports the bearings are too small for xxx-sct wheels, while another notes the xxx-sct front takes 5x10 bearings, which would explain the mismatch. Reviews are few and one contains a fit complaint that appears to stem from ordering the wrong size, so the fit issue is not clearly a product defect.

  • + Good quality
  • + Low price, about $1 each
  • + Useful as spares
  • − Reported not to fit xxx-sct wheels
  • − Fit issue may be due to wrong bearing size
