Review on 40X68X15Mm Performance Cost Effective Pre Lubricated Bearings by Craig Shah

I was very impressed with the quality of these bearings. I bought expensive factory bearings for our CBC NCNC 1100 s3 machine and the spindle was so noisy. Decided to give these bearings a try and an amazing 90% noise reduction and a much cooler spindle, great purchase and made in the USA. I highly recommend these camps.
