Are Nylon Retainers good for Skating Applications?
The jury is still out on this one. The Nylon Retainer (Cage) is usually used in high speed bearing applications, so its use in skating applications would normally not be necessary. The Nylon Retainer may have some slight advantages over the Steel Retainer in that it could possibly help to dampen the shock loads associated with skating, and it may assist in holding the lubricant in. More testing would be required, however unless somebody comes up with an inexpensive version of this type of retainer, the steel retainer would probably still be the most economical type over a period of time.
