Ball bearings are wear items, similar to the chain on your bicycle. While we went out of our way to present you with the best possible product, your Kogel Bearings do require some maintenance and a new seal kit from time to time. Please download this service document from our manuals section for a step by step on how to keep your bearings running smoothly.
