3 Quality Features VARMEC GEAR REDUCERS Features that make Varmec a premium gear reducer: All Varmec gearboxes are computer-designed and conform to AGMA2001- B88 standards. All Varmec casings are made from high quality gray cast-iron and are solid-body construction which greatly reduces leakage. All Varmec components are machined on modern CNC machining centers. All Varmec gears are made from nickel chrome moly alloy steel that is hardened and profile ground. All Varmec primary gear sets are ground to at least an AGMA12 finish. All Varmec secondary gear sets and beyond are at least an AGMA11 finish. All Varmec input shafts are made from hardened and tempered nickel chrome alloy steel. All Varmec output shafts are made from high-strength nickel chrome moly alloy steel. All Varmec gearboxes are coated with thermosetting orange-peel powder-based polyester and epoxy resin paint. All bearings and seals used in Varmec gear boxes are standard off-the-shelf items. All Varmec gearboxes use synthetic oil. Varmec s double and triple reduction gearboxes have the same boundary dimensions. Varmec reducers accept standard NEMA C-face motors. The motor can be removed without disassembly of the gearbox. 2 Varmec Gear Reducer Catalog

4 Numbering System and Selections The first 2 digits represent the output shaft size in millimeters (closest inch dimension for U.S. market). The third digit represents the number of reduction stages.

Determine the class of service from this chart AGMA Class of Se rvice Operating Conditions Light Shock - not more than 10 hours per day Moderate Shock - not more than 15 minutes in 2 hours Light Shock - 10 to 24 hours per day Moderate Shock - not more than 10 hours per day Heavy Shock - not more than 15 minutes in 2 hours Moderate Shock - 10 to 24 hours per day Heavy Shock - not more than 10 hours per day Se rvice Fa ctor For class or class service and 1750 RPM input, use the quick selection chart (page 5 for class and page 6 for class ) to determine appropriate size based on your hp requirement and desired output RPM. 3. For class service, please consult your local Varmec distributor. 4. Use the horsepower tables for the appropriate size to get the exact output RPM and capacity, with 1750 RPM input. For 3450 or 1200 RPM input, consult your local Varmec distributor. Varmec Gear Reducer Catalog 3
