Kits do not include instructions, read and follow equipment manufacturers' instructions for replacing seals. Some kits may include extra parts because they are made to fit the design variations of a particular model. Kits for rod glands with pressed in metallic bearings (such as bronze) generally will not contain a replacement bearing, however phenolic & plastic bearings are normally included. If a bearing is available separately we will let you know. Because seal designs are continuously improving, and because of possible previous repairs, some kits may have a different seal design than the seal you remove, however, unless the original seal grooves were machined in a previous repair the replacement seals should fit & function properly. Never attempt to service a pressurized cylinder, or a cylinder connected to a load, never use air or hydraulic pressure to disassemble a cylinder. These are top quality aftermarket replacement parts, we are not affiliated with any equipment manufacturer.
