description
- All standard stock miter gears must be mounted at right angles (90°) for proper tooth bearings.
features
- All Martin Gears are cut with the 20° pressure angle system
- Hardened miter gears have approximately 50% more horsepower capacity and provide greater gear wear than untreated gears
- The mounting distance must be held in order to maintain proper bachlash between gears. The use of a straight mineral oil as a lubricant is recommended for most miter gear applications
