Shaft differential eliminates backlash
A patented precision shaft differential features built-in antibacklash characteristics for eliminating play in shaft rotations.
A patented precision shaft differential, manufactured by Sterling Instrument, features built-in antibacklash characteristics for eliminating play in shaft rotations The differential, identified as Catalog No S9540A-TS9, provides a high level of precision in instrument drives and other types of quality applications and is particularly effective in designs involving the adding and subtracting of shaft rotations in servo systems

The process of selecting small inch size drive components for new prototypes or production applications just became easier.
The 2.250in long patented unit (Patent 3,137,181) consists of three stainless steel bevel gears plus a central spider block.
Sterling's end gears, when ordered at the same time as the differential, are assembled without charge to the differential shafts.
Within the rated torque and speed, the backlash between the end gears when a S9540A-TS9 antibacklash differential is employed will be zero.
This compares to a maximum backlash of 10arc-min between end gears when a standard differential is used.
Availability is from stock.
The price in single-unit quantity is $305.35.
