Boston Gear 68951 25 500 REEL STEEL ROLLERLESS CHAIN

When used with worm gears, Boston Gear worms provide an effective answer for power transmission applications requiring high ratio speed reduction in a limited space using right angle (90°), non-intersecting shafts. Manufactured from acetal, nylon, and hardened and unhardened steel, they offer the smoothest, quietest form of gearing when properly applied. Because the efficiency of a worm gear drive depends on the lead angle and number of starts on the worm, it important to keep the ratio as low as possible. It is equally important that worms and worm gears used together must have the same diametrical pitch and threads.Product FamilyWormsDiametrical Pitch24Bore Size0.250Product DescriptionWorm, 24 DP, 25 PA, .500 PD, RH, Steel/HardenedAltra Master No.30217402Straight Spiral ToothSpiral ToothMaterialSteel, Hard-G & P ThreadMating Gear24 DP, Quad ThreadUPC781711130605HandRight HandFamily Id30,064Weight0.041Face (Thread Length)0.813KWY/Setscrew/OtherW/.0938 Hole OnlyPitch Diameter0.500Outside Diameter0.580Hub Diameter0.370Unit Of MeasureEnglish
