The basic function of the seal is twofold - to keep contaminants out and to keep the lubricant in. The three types of seals differ in their sealing ability, how freely they let the bearing spin, and of course cost. Sealing ability refers to the ability of the seal to keep debris and contaminants out of the inner workings of the bearings. The better the seal, the less often you have to clean your bearings to keep them running smoothly. Failure to clean your bearings when needed will shorten their lifespan. If you want bearings that need very little maintenance, rubber sealed bearings require very little to no attention as they offer the tightest seal.. Metal shielded bearings require the most maintenance.How Freely the Seal lets the bearing spin is directly related to the performance of the bearings. A rubber sealed bearing offers lower performance than the other types of seals because the rubber seal is actually in contact with the inner workings of the bearing, which results in higher friction as the balls rub against the rubber seals. Metal Shields, Teflon, and Polyamide Seals are "non-contact" as they are held in place away from the inner workings of the bearing. They let the bearing spin easier and offer noticeably higher performance. Cost is always important in our hobby, and the type of seal does affect the cost of the bearing. The Chart below shows a comparison of the cost of the various bearings. Metal Shielded bearings are the least expensive, while PolyAmide sealed bearings are the most expensive (except for ceramic bearings which can cost you up to $400 for a set).

It is only used by companies to help build name recognition. MATERIALS: T are two major types of materials used in the construction of Hobby Sized bearings - Chrome Steel and Stainless Steel. Both are excellent bearing materials. The main differences between the two are corrosion resistance and cost. Chrome Steel is slightly less expensive than Stainless Steel and will function very well under ordinary use (on or off-road), and under extreme use if properly maintained... read more
