Why Use Oil-free Bushings?

Graphite plugged bushings are beneficial anytime an application needs ongoing lubrication but also needs to perform for long periods without maintenance. These bearings are self-lubricating, so additional oil and grease are not needed.

Because graphite plugged bearings self-lubricate, money is saved on maintenance and replacement—both in materials and labor costs. Additionally, less downtime is needed to add more lubricant or perform other everyday maintenance tasks. Graphite plugged bushings have better wear resistance than other types of bearings. This is because when graphite plugged bushings are in use, there are very minimal friction thanks to the lubricant film they produce. Friction is what wears parts down and causes them to need eventual replacement, so limiting this is the key to durability.
