Gears - Solid & Split

Split Gears
When using an AI-Tek speed sensor in RPM measurement, split gears provide a convenient and simple means of installation where shaft disassembly is not feasible. The two halves of the gear are fastened with clamping screws, thus assuring close fit. All split gears are 12 diametral pitch, 14.5∫ pressure angle.

Solid Gears
AI-Tek also offers a 20 diametral pitch, 14.5∫ pressure angle, solid steel gear. This gear can be rebored to fit shaft diameters up to 1.375". It is secured to the shaft with 2 set screws.

Note: Gears are supplied with minimum bores as shown. Alternate bores within the minimum and maximum limits are available at additional cost.
Caution: Gears may shatter if not installed to specifications or if operated above maximum RPM.
