Keystone Series Gearing
The Keystone Series gearing was designed according to latest AGMA 2001 standards. Protuberance hobs with a 250 normal pressure angle are used along with shot peening to obtain high bending strength capacity. Premium bearing quality alloy steels are given a computer controlled carburized cycle to obtain a deep case depth on tooth flanks and roots. Gear grinding operations include tip, root, and lead modifications to insure long operating life.
Keystone Series Housings
The Keystone Series offers both cast iron and fabricated steel housings. Our in-house pattern making permits rapid response for economical custom configurations while giving us complete control over features that most affect casting strength and integrity.. Heavy duty fabricated steel housings are available in all sizes and can be quickly customized to meet individual needs. All fabricated steel housings receive a thermal stress relief prior to machining. Housings feature heavy duty bolting, multiple oil drains, air vents, oil level sight gauges, threaded water tight inspection ports, and o-ring sealed retainers.
