Yea but for the same price you get Rating of #5 instead of #7....from Acer.
I just bought a set this morning. I had them in my TC3 before I got my Yokomo, super high quality and as long as you took care of them they will last a very long time.
Just my $0.02
This is from acer's web site:
Lightweight ceramic balls dramatically decrease the centrifugal force placed by the balls on the rings. This, in addition to a 50% higher modulus of elasticity than conventional bearings, and "Grade 5" smoothness of the balls (contrary to popular belief the lower the Grade number a ball is, the rounder and smoother it is), produce a lower coefficient of friction at the ball-raceway interface, leading to over 33% less friction in the bearing as compared to conventional bearings, and far less wear, lasting an average of ten times longer than conventional bearings. Sealed with our exclusive no contact seals for the lowest friction and best dirt resistance. These are the best and most high tech seals available.
where did you get the abec 7 rating????????
this is the email that I received from boca:
We have a Ceramic Bearing kit for the Tamiya 415 which we can offer you in the following:
Kit #55-400C-YZ (16) Stainless Steel Ceramic Bearings with metal shields……………… $99.95.
Kit #55-400C-YS (16) Stainless Steel Ceramic Bearings with rubber seals……………….$115.95. Recommended for gas engine cars/trucks – Maintenance Free.
Kit #55-400C-YU (16) Stainless Steel Ceramic Bearings with Ultra Seals………………...$115.95. Recommended for Electric Cars/trucks – Maintenance Free.
We do not offer an ABEC 7 Ceramic Kit. The difference in cost would be at least double and the difference in performance would be negligible
Only thing is there rated at abec #1, I'm waiting for Surge to email me back, their's rated at abec #5 but since they don't sell them as a set for the 415 they'll see what they can do for me!
