To Assemble and Adjust a BUS Unit

1. If the BUS housing has felt “wipers” (unit will be denoted by “W/W”), spray both thoroughly with LPS2 lubricant. Slowly pull out the bearing retainment insert ( foam tube). The bearings within a “W/W” type housing should stay in place. Now carefully begin inserting the ram by angling it slightly and by moving it back and forth, slowly sliding it into the housing and enclosed bearings through the first wiper. A small flat bladed screwdriver often helps to “massage” the oil soaked felt into admitting the ram. Once through the first felt wiper, slowly slide the ram to the opposite side’s wiper and, again, using the screwdriver gently massage the ram through. Once the ram is through the unit, the felts will take a set and work well for both lubrication assistance and protection of the bearings from outside contamination for a long period of time.

If the BUS housing is one that is “without” wipers (will be denoted by a “W/O”), then simply pull out the bearing retainment insert partially and as you are doing so, slowly slide the ram into the housing. This will keep the bearings in their proper position until the ram is completely though the unit.

2. Now the ram and bearings should be at their pre-adjusted positions; however, often the end user has varying applications with specific “running fit” requirements. Having the ability to “adjust” this is an advantage of our Turnomat bearing systems. If this running fit is either too loose or too tight, adjustment is made as follows:

Loosen the lock nuts on the bearing adjustment screws on the “top” and one side of your BUS housing. Series 625 and 1000 will have a total of (4) of these adjustment screws and series 1500, 2000 and 2500 will have (8).

Once these nuts are loosened, slightly adjust the screws in or out (depending upon) whether to increase or decrease “running fit”. Once the proper fit is attained, lock them back down and test operation of your ram again. If satisfactory, you are done, if not … repeat the same procedure. Be very careful not to change the setting of the screws when tightening the lock nuts down.

Once again, it is always advisable to re-lubricate the wipers if they apply.
