Which bearings are best? All our bearings are manufactured with the finest quality products and are hand inspected before being shipped. For racing and track applications we recommend the Ceramic Nitride Pro Series RC bearings due to the fact that they will drastically improve acceleration and snap out of the corners, and are much more resistant to high performance, high RPM and high heat RC racing conditions. These are the same bearings used by our ACER Racing team racers such as Greg Degani, Chad Bradley, Andrew Smolnik and Jeremy Kortz, not to mention other world and national champion racers who use them in their cars. They are super lightweight due the low mass of the Ceramic Nitride Pro Series balls which weigh 79% less than tungsten carbide. This provides for lower centrifugal force and much lower friction. Simply put, these are the best. The Dual Super Polyamide Sealed rc bearings are also an excellent choice. While the HCCA ultralite balls are not as light as the Ceramic Nitride Pro Series balls, they are lighter than conventional bearings and are a very durable bearing for all applications. The Teflasonic rc bearings are a tried and tested bearing great for the budget minded RCer. These are just as durable as the Polyamide Sealed rc bearings but use grease for lubrication and have low resistant dual PTFE seal.
Do I need to lube my bearings or are they prelubed? All the bearings are prelubed and do not need lubrication prior to installation. The Ceramic Nitride Pro Seriesrc bearings use our special synthetic lightweight oil which we allow to ionically bond to the balls and eventually the bearing race before being shipped to you. Some racers obviously like to relube or clean after several races: this is not necessary but is acceptable.
What is the difference between the three different types of differential balls? Weight is the biggest difference. The Ceramic Nitride Pro Series are the lightest by far, then the HCCA ultralite, then the tungsten carbide. The lower the weight the lower the rotational mass meaning the higher the acceleration and top speed. Low weight differentials are critical for racing applications. Contrary to popular belief, Ceramic diff balls are actually more durable than even Tungsten Carbide, and they will not crack or break. So for racing purposes the Ceramic Nitride ProSeries differential balls are absolutely the best.
Are your ceramic differential balls only coated with ceramic?
NO! All our ceramic differential balls are 100% Silicon Nitride and are NOT merely ceramic coated steel. Our ceramic differential balls will also NOT crack or shatter as they are made from the finest aerospace grade silicon nitride. These ceramic differential balls are also polished to a mirror finish for the ultimate in smoothness and friction free performance.
Why are the widths not listed for the bearings? Our rc bearings are listed by their inner diameter x outer diameter, i.e. 5 x 10 mm is a 5mm inner diameter and 10mm outer diameter. The widths are not listed because they are always standard. There are a few sizes we do list the widths for because they are non-standard widths but usually they are standard.
Can I buy ACER Racing products from my local hobby store? YES. We are distributed through Great Planes / Hobbico. Your hobby store can order through them or you can buy directly from our website.
How do I get sponsored by ACER Racing? RC racing is an amazing sport and we support all those who are involved in this great hobby. Unfortunately due to the large number of sponsorship requests we receive we are only able to sponsor National and World Champion racers. Keep up the racing though and who knows, you may be the next ACER Racer!
I know someone who wants to be the next ACER Chick, what do I do? We are always looking for the next ACER Chick. If you would like to be considered please mail or email us your photos and specifications (height, measurements etc). All models must be at least 18 years of age.
