Sterling Instrument’s Anti-Backlash Gears Eliminate Marred Shafts

A new series of 1158 anti-backlash gears manufactured by Sterling Instruments feature the Fairloc integral hub fastening system, which eliminates marred shafts. According to the company’s press release, the fastening system helps adjustment, timing and frequent removal problems with full component support along the entire hub system. In addition, the self-contained gears offer a small gear hub envelope. Each gear comprises a set of two gear halves that give the appearance of a split gear. Built-in springs, mounted around the hub, force the two gear halves to turn in opposing directions relative to one another until the tooth space between the inner and outer mating gear is filled. This technique is applied to gears with diameters down to 0.642" to eliminate backlash in gear trains.
