3 BDU - Series The BDU-Series is a belt driven guided linear motion system utilizing a tooth-profiled belt to control position of its moving carriage. This belt driven design provides modest load carrying capacity, high speed and very long stroke capabilities. The BDU-Series requires a motor of some type to drive the unit. Motors include stepper, servo, AC/DC synchronous and air drives. The BDU-Series is designed for moving loads at high speeds over greater distances with relative positioning accuracies. This product has not been designed for precision positioning accuracies. For applications requiring precision positioning, refer to BSG Ball Screw Gantry Series. NMC does not recommend the BDU-Series in vertical applications. Features and Benefits: A. Body: Body Profile extruded aluminum, rigid, light weight Rigid Design internal stiffening ribs support carriage Side Slots... for position switch mounting and foot mounting brackets B. Carriage: Guided and Supported body extrusion geometry supports carriage motion Robalon Bearings synthetic bearing material for high speed applications Thread Inserts secure mounting for high speed application NuMate Direct Mounting Pattern other Numatics Motion Control products mount directly to carriage without adapters or transition plates increased flexibility, cost and time savings C. Drive Belt: Steel Reinforced Polyurethane. light weight, high strength, low stretch Trapezoid Profile eliminates slip, greater accuracy Belt Cover protects belt from contamination, not available on the BDU50 Series D. End Cap: Belt Tensioning System easy access, easy adjustment E. Output Shaft: Dual Output Shaft accessible from both sides of body, motor mounting from both sides Protective Cover molded plastic, covers rotating shaft end opposite of motor, protects F. Motor Mount Assembly: Cast Motor Flange for NEMA 23, 34 and 42 frame motors E A D F B C 3
