BLT63-2 Translator

The McAllister Technical Services' (MTS) Bellows Sealed Linear Translator (BLT) is the finest of its kind available anywhere. We recognize and appreciate the confidence our customers have placed in our company and we work hard to earn it.

Despite its modest price, the BLT63 will provide years of trouble-free service, especially if simple maintenance is performed. The three jacking screws and included ratchet actuator provide a short compressed height (see drawing) for extra rigidity and flexibility.

The BLT63s use double ball bearings. The screws and bearings are dry lubricated with high temperature lubrication for low friction and long life. All parts are field replaceable. All translators are also available with long strokes, motor drives, linear encoders, tapped flanges and special heights.

Maintenance:

The BLT63 needs only minimal maintenance. The linear bearings are self-lubricating, and the guide rods need only be kept clean and free from dirt, dust and debris. The jacking screw and bearing do, however, need periodic lubrication. As delivered, the screws and ball bearings are coated with high temperature grease which will degrade over time, due to moisture in the atmosphere. After each bakeout, lightly relubricate the screws with the (provided) grease. Be especially careful to not use a hydrocarbon grease such as Felpro C100TM unless you periodically clean the oxidized residue from all load-bearing surfaces. The normal bakeout temperature is 150°C but higher temperatures can be used, if needed. For bakeouts between 150°C and 210°C, increase the frequency and thoroughness of lubrication.

On both the 3-ear and the 6-ear models, the flanges may need to be re-aligned to parallel after removing or replacing the chain. Should it become necessary to adjust the alignment of the two flanges:
