MARTIN SPROCKET & GEAR — MARTIN SPROCKET & GEAR 2080B21
- Double pitch sprockets have rollers of the same diameters and widths as American Standard Roller Chains of one half the conveyor chain pitch.
- Engaged by every other tooth, double duty sprockets have two teeth per chain pitch.
- During each revolution only half the teeth function effectively.
- Sprockets with odd numbers of teeth will allow any given tooth to engage only on every other revolution, automatically increasing sprocket life.
- Double duty sprockets with even number of teeth may be manually advanced one tooth periodically to increase sprocket life.
