Cautions / Prohibitions

·Dropping or hitting may damage the product.
·Please note that when shock was applied, the product may lose its function even though there is no visible damage outside.
·Cam Followers can bear radial load, but they are not designed to support thrust load. Please avoid using them to bear thrust load.
·Some types are not filled with grease depending on the size.
See the table below and lubricate the ones not filled with the grease before using them.
