SERVICE & MAINTENANCE INSTRUCTIONS
Linear Thrusters are precise but simple linear actuators which utilize high pressure air (up to 250 PSI) or low pressure hydraulic fluid (up to 500 PSI) for their motive power. Air cylinders are pre-lubricated at the factory and should be used with a filter-lubricator combination for best results. Otherwise, introduce a few drops of 10 weight oil into the cylinder every 500 hours of operation. Hydraulic cylinders should be used only with clean hydraulic fluid compatible with Buna N Seals.
Two spring loaded oiler ports are located on the face of the Linear Thruster housings. Introduce several drops of 10 weight oil into each port for every 100 hours of normal operation, more often if rapid cycling is necessary.
CAUTION: When removing or replacing the air or hydraulic cylinder be sure that the cylinder mounting nut is not over tightened. This nut should be tightened down and then backed off approximately 1/8 turn so that the air cylinder floats within the retaining shelf. This is to prevent binding of the cylinder rod and undue wear on the cylinder rod bearing or seal.
CAUTION: When utilizing the four tapped holes on the back of the Linear Thruster housing, take care to insure that the fasteners used are not long enough to contact the linear bearings. The outside cases of the bearings are very fragile and can be easily damaged by over-long screws.
Technical Information
REPLACEMENT OF BEARINGS & SEALS
Worn or damaged linear bearings can be pressed out of the housing after first removing the seals from both ends of the bores. The seals are pressed into the bores and can easily be prized out with a screwdriver or similar tool. Utilize a mandrel slightly smaller than bore and proceed carefully so as not to damage the bore inside diameter. Any traces of Loctite remaining within the bore should be carefully removed by scraping. Replacement bearings should easily slide into the bore with moderate finger pressure. Spread two to four drops of Loctite RC/680 around the bearing case, insert into the bore and rotate while pressing flush with the top of the housing. Set the seal atop the bearings and immediately force it into the bore using a mechanical or hydraulic press. Repeat this procedure for the other bearings and allow about 30 to 40 minutes setup time before returning the housing to service.
