Needle Roller & Cage Types use a roller style rolling element to reduce friction of a rotating surface without the need for an inside or outside race. Needle Roller & Cage Types have a high load carrying capacity with a very small cross section height and consist of a retainer and rollers only. The needle rollers are guided parallel to the axis using a cage retainer. Needle Roller & Cage Types have a larger surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less clearance, or the difference between the diameter of the shaft and the diameter of the bearing, so they are much more compact. The typical structure consists of a needle cage which orients and contains the needle rollers and, the needle rollers themselves. Needle Roller & Cage Types are heavily used in engine components...more »
Industrial lubricants are oils, greases and other substances designed to reduce friction, binding or wear. Specialized characteristics may enhance thermal conduction or reduce electrical resistivity. Other industrial lubricants can provide sealing against moisture. Industrial lubricants are available in many forms such as low viscosity oils..more »
Lightning Lube Technology is specially designed to form a molecular bond with all moving metal parts within any application. Use it to reduce friction, improve performance, decrease wear and extend life. Lightning Lube can be used when installing new bearings and components or to preserve your existing bearings and components..more »
Q: How do your different RC bearing lines compare to the stock bearings that came pre-installed. How much longer will they last?

A: Unfortunately there is never an explicit warranty with bearings. Bearings do eventually wear out and every application, setup and operator is different. It is very difficult to calculate life expectancy without having extremely detailed data about your application. But Boca Bearings has been in business since 1987 and we stand behind our product 100%. We will always replace or exchange any bearings that we determine to have failed prematurely. As a rule of thumb we would say:

Our Econo Power shielded bearings are comparable to what comes stock with your vehicle, so you should expect the same life as those that you get right out of the box with your car. Because these are shielded bearings they will require maintenance to get a long life. You will want to clean and re-lube them regularly to extend the life or you will have to replace them often.

Our Green Seal & Ultra Seal bearings however are considered maintenance free and lubed for the life of the bearing. You do not have to ever clean or re-lube these bearings at all and they should last at least twice as long as your stock bearings.

And finally our Ceramic Lightning Yellow Seal & Ultra Seal bearings are also considered maintenance free and lubed for the life of the bearing. But because the ceramic ball is so much harder than steel you should expect about 3-4 times the life of your stock bearings.
