The ULTRA Air Bearing Kit is a solution for replacing worn bearings on the ULTRA Air Blaster V2. Over time, condensation in an air compressor can cause moisture buildup in bearings and cause extra wear and tear. This bearing replacement is a quick and easy solution to give your Blaster a new lease on life! To replace the bearing, simply twist off the cone from your ULTRA Air Blaster. Give the bearing and nozzle a tug and pul the entire bearing assembly from the blaster. Clean the inside of the gun with a light cleaner and some Q-tips. Drop in a NEW bearing and re-assemble the blaster. Pro Tip: To extend the life of your bearings, we highly recommend an inline filter for your air compressor. This will help separate the moisture and keep it from getting into the bearings on the blaster. It's also recommended to check the bearings every few dozen details. Give the bearing a clean with a Microfiber towel and re-lube as needed.
