Precision Heavy-Duty Motorized Rotation Stage OMZT-B Series
Rotation shaft system and tabletop of stainless steel, precision-machined through multiple processes for high rigidity, high flatness, precise fit, strong load capacity and long life.; Precision-ground worm-gear transmission for high positioning performance.; High-grade cross-roller bearing ring for high motion characteristics.; Stepper motor and worm connected by a high-quality flexible coupling for synchronous transmission and elimination of backlash and form/position errors.; Stepper and servo electrical accessories available, with technical support and product customization.
Product Introduction
The OMZT-B precision heavy-duty motorized rotation stage is developed on the basis of the OMZT-A cost-effective heavy-duty rotation stage, with ultra-high rotation accuracy and high rigidity. It uses a cross-roller bearing ring, precision-ground worm gear and a unique stainless-steel shaft system and tabletop, ensuring high rotation accuracy and rigidity so that key indicators such as rotation accuracy, axial runout and radial runout reach the industry-advanced level. The unique worm-gear adjustment structure conveniently eliminates mechanical errors for long-term accuracy. The series offers high load capacity.
