Highlighted among the 5,129 products in the catalog are NEMA size single and double stage in-line and single, double, and triple stage right angle planetary gearheads. Servo motors, stepper motors, and gearmotors in various inch and metric sizes along with optical rotary encoders are shown. The catalog shows technical specifications for NEMA Sizes 17, 23, 34 and 42 and Metric sizes 60, 90 and 115 planetary gearheads which are offered in 8 gear ratios between 3:1 to 100:1. Using aluminum housings and heat-treated steel gears, these precision assemblies feature true planetary gear design with low backlash of 8 to 15 minutes respectively. The maximum rated torqueranges for these rugged units are between 23 lb. in. (2.6 N•m) and 1,513 lb. in. (171 N•m). For NEMA sizes, the shaft loading range is 20 lbs. to 120 lbs. radial and 138 lbs. to 270 lbs. at 250 rpm output axial. For metric sizes, the shaft loading range is 375 N to 750 N radial and 1798 N to 4793 N at 250 rpm output axial. Shaft diameters range from .2500" to .6250" for NEMA sizes and 16 mm to 24 mm for metric sizes. For ease of installation, all mounting hardware is included. In addition, designers can select from Bu-Ord Sizes 8, 11, 15 and 18 gearheads and speed reducers, commercial size gearheads and speed reducers, metric size motors and gearmotors and a vast selection of right angle drives.
