Martin Hi-Cap® 8 3V 530 SK Solid Type A-1 Wedge Stock Sheave, 1/2 to 2-5/8 in QD® Bushed Bore, 5.3 in OD, 8 Grooves, 5-1/4 in Dia Pitch, 3.531 in W Face

Hi-Cap® sheaves (narrow V-belts) are manufactured from class 30 gray iron (30,000 tensile strength) and can have a maximum speed of 6500 fpm. All Martin sheaves are statically balanced. Dynamic balancing should be considered for any sheaves exceeding 5000 fpm, or if they will be used on equipment where vibration is a problem. Martin has extensive inventories of both QD and TB style V-belt sheaves to run with 3V, 5V, and 8V belts.

Martin W1230 Reborable Web Worm Gear, 12 Diametral Pitch, 14.5 deg Pressure Angle, Single Threads, Right Hand Rotation, 30 Teeth, 2-1/2 in Dia Pitch, 0.5 to 0.626 in Dia Bore, 1/2 in W Face, Cast Iron

Worms and worm gears are used to power right angle, nonintersecting shafts. In normal applications the worm gear is driven by the worm. The most popular use of worms and worm gears is in applications where high ratio speed reduction is desired in a relatively limited space. They are also used in applications where high resistance to the worm gear shaft reversing and driving back through the worm is desired.

Martin W1230Q Plain Reborable Worm Gear, 12 Diametral Pitch, 14.5 deg Pressure Angle, 4 Threads, Right Hand Rotation, 30 Teeth, 1 in Dia Pitch, 0.75 to 0.8135 in Dia Bore, 1/2 in W Face, Cast Iron

Worms and worm gears are used to power right angle, non-intersecting shafts. In normal applications the worm gear is driven by the worm. The most popular use of worms and worm gears is in applications where high ratio speed reduction is desired in a relatively limited space. They are also used in applications where high resistance to the worm gear shaft reversing and driving back through the worm is desired.

Martin W840 Reborable Web Worm Gear, 8 Diametral Pitch, 14.5 deg Pressure Angle, Single Threads, Right Hand Rotation, 40 Teeth, 5 in Dia Pitch, 1 to 1.439 in Dia Bore, 3/4 in W Face, Cast Iron
