Boston 30217398 13052 HDSH-1 STEEL GEAR-H/WORM

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 Pitch48Bore Size0.190Product DescriptionWorm, 48 DP, 20 PA, .333 PD, RH, Steel/HardenedAltra Master No.30217398Straight Spiral ToothSpiral ToothMaterialSteel, Hard-Polished ThreadMating Gear48 DP, Double ThreadUPC781711130520HandRight HandFamily Id30,064Weight0.061Face (Thread Length)0.563KWY/Setscrew/OtherW/.0625 Hole OnlyPitch Diameter0.333Outside Diameter0.380Hub Diameter0.260Unit Of MeasureEnglish
