Servo Planetary Gearboxes

Sesame’s planetary gearboxes are designed for servo applications requiring low backlash, high dynamic performance, compact size and long lifetime. The range includes premium, high precision, standard and economy ranges, optimised to suit the application requirements. Offered with a variety of backlash levels, the Sesame gearbox range includes standard output shaft variants, output flange shafts and right angle gearbox solutions. The wide range of sizes and designs allows optimal selection, with the range including spur and helical gears. The internal gear ring and housing are manufactured from a single component, ensuring maximum rigidity and concentricity. A wide range of ratios and housing designs, results in interchangeability with other manufacturers. Special surface treatments, paint finishes, and stainless steel are available for those more demanding environments.
