Quality at MasterDrive begins with our selection and certification of raw materials used by our foundry operations through our exacting machining, balancing, and warehousing. Our Quality Management System is in compliance with ISO 9001:2015.
Element Materials Technology (Formerly Stork Technimet) in New Berlin, WI is an A2LA accredited metallurgical testing facilty that performs all testing and analysis on materials as well as completed products. Testing includes material compliance verifications with chemical analysis, tensile tests, hardness, torsional fatigue testing, failure analysis, runouts and imbalance, and competitive product benchmarking for strength and corrosion resistance via salt spray tests.
All MasterDrive products are produced by a single foundry source that we have partnered with since the beginning of the company. Castings are certified to GB, ANSI/ASTM, DIN, JIS, BS and ISO standards. The foundry works in conjuction with 11 controlled machining facilities that handle over 3 million pieces per year. All production prints, production tools and inspections are handled by over 30 quality technicians.
At the foundries all cast parts are inspected for hardness and strength, blow holes, porosity, flaws, bumps and holes, cracks and mold marks. During and after machining in the company’s facilities products are checked for bore and belt groove finish, thru hole position and threaded hole fits, belt grooves are checked for width, pitch, depth, angle and edge width. Taper bores are checked for aspect diameters and cone angles. Lengths of all surfaces are checked against the prints and runouts are noted. Finally, parts are checked for balance, stamping of identification information, and surface treatments.
Both Sheaves and Bushings are phosphate coated for corrosion resistance. Utilizing the phosphate coating as a base, our sheaves are then given an attractive grey baked enamel finish for lasting durability.
MasterDrive® offers a complete line of single and multi-groove sheaves, from bored-to-size and H bushed, to heavy duty QD sheaves.
MasterDrive® Inc. sheaves and bushings are manufactured to meet or exceed the current ASTM/SAE specifications for gray iron casting.
Sheaves are accurately machined from gray cast iron, statically balanced, painted and individually packaged. All are furnished with standard keyways and set screws. All set screws are 5/16-18 knurled.
Sheaves are phosphorated before painting to prevent rust and increase cohesion between paint and metal. The durable, machine gray, baked enamel outer finish offers a long-lasting clean appearance.
All sheaves are balanced for smooth trouble free operation.

BUSHINGS for every application.
(All of our bushings are stocked in inch and metric sizes.)
All bushings are manufactured to MPTA standards.
Those standards can be viewed here:

Weld-On Hubs are available in 3 styles to suit the user’s preference for bushing mounting types. They are stocked for use with:
All MasterDrive Weld-On Hubs are machined from steel.
Weld-On Hubs are commonly used with plate type sprockets and conveyor pulleys to provide for more shaft engagement.

Accepts DST-Double Split Taper style bushings.
These bushings are keyed to both the shaft and hub. The external key provides positive drive with no torque on the cap screws. DST bushings allow for the highest torque carrying capability.
MasterDrive offers 4 series of industrial belts:
Standard wrapped V-Belts are commonly used for power transmission. These belts are used on applications ranging from light duty power transmission to heavy duty machines like printing machines, machine tools and crusher.
Narrow Wrapped V-Belts feature a higher wedge angle and hier power transmission in an energy-saving compact design. They tend to be used on large pumps, crushers, dynamos, machine tools and freezers.
Thin Wrapped V-Belts have higher bending properties, good abrasion resistance, little generation of powder and are commonly found on agricultural machinery and light duty industrial applications.
These belts are designed for applications where more than one belt is required. They help prevent belt whip and provide for stable running.
These belts feature improved transmission efficiency since they are composed of cord and rubber with side faces of fabric. Applications include agricultural machinery, blowers, dynamos and escalators.
Designed for applications where multiple belts are required. Help prevent belt whip and jumping. Lateral rigidity keeps belt running in a straight line for reduced wear.

Belt, Sheave and Bushing Selections
When systems requirements will not allow slippage, synchronous components such as Timing Pulleys and Belts are utilized.
Timing Pulleys resemble gears with rounded teeth and engage with a mating toothed belt.
They offer an advantage over chain drives by allowing much higher operating speeds, high efficiency and no lubrication. They are also commonly found in areas where access for maintenance is difficult.
MasterDrive offers both the popular ‘L’ and ‘H’ Pitch configurations in Solid, Webbed and Spoked options.
The pulleys are straight bored for small sizes and TB Bushed.
