Lifetime lubrication in Zero-Max “Crown” gear drives assures motion system designers of a smooth operating, quiet right angle gear drive that needs no maintenance. These drives are designed for economical transfer of speed or power. Lubricated for life with Beacon 325 premium grade grease, Zero-Max Crown drives feature heat treated AGMA Class 10 spiral bevel gears. This combination of bearing design and lubrication formulation ensures long-term, maintenance free operation for demanding industrial applications. The drives feature precision hardened and ground ball bearings with non-magnetic steel shafts for handling speeds up to 2,000 rpm in most operating environments. The internal gears are permanently mounted to the shafts with locking pins. This provides a very resilient and durable connection for use in heavy load applications while requiring no maintenance. Sealed-for-life systems using motors, generators and similar equipment in industrial applications require an equally robust gear drive. Crown drives provide that and more. Lubrication with Beacon 325 grease ensures optimum performance in temperature ranges from -50° C to +120° C without evaporation.
Zero-Max ensures their drives are predictably smooth operating, and similar model sizes have identical performance characteristics when designed into multiple drive setups. To accomplish this, Zero-Max drives are precision assembled for perfect bearing and gear alignment. The drives are pre-lubricated during assembly, then completely enclosed in a heavy-duty anodized aluminum housing. The housing is designed for maximum strength and heat dissipation. This design ensures that internal gears stay permanently aligned, lubricated and free of contamination from outside debris.
Zero-Max Crown drives are used throughout dozens of industries in hundreds of applications. Among these are food processing, packaging and material handling systems. Available in many sizes and models, Crown Drives are ideal for a wide range of horsepower, torque and shaft speed requirements. Standard two and three way models are available with 1:1 and 2:1 speed ratios in shaft diameter combinations of 3/8, 1/2, 5/8 and 3/4 inch.
