Encoder applications require an exceedingly higher level of precision to ensure proper translation of motion into digital signals. Regular gearboxes often meet requirements for reliable speed reduction but produce equipment backlash that impacts precision. Low backlash inline gearboxes provide a solution by enhancing smoothness and positioning precision while minimizing motor sound in high speed, high precision applications.
Improve Positioning Accuracy with Low Backlash Gearboxes
Ever-power is one of the world’s leading manufacturers of high-overall performance low-backlash gearboxes. Our SRX Series low backlash inline gearboxes are specially engineered to deliver the precision necessary for encoder applications. You can expect quickness reducers in a wide variety of gear ratios and shaft sizes to meet up your unique needs.

Order an SRX Series inline speed reduction gearbox for the application or contact us to find out more.
High-Performance Low Backlash Inline Gearboxes
Ever-power’ SRX in-line velocity reducers are rated for boosts to 3,000 RPM. These speed decrease gearboxes employ a low moment of inertia at the input shaft (as low as 0.015 gm-cm2). Two frame sizes are available, with equipment ratios from 4.96:1 up to 3,600:1. Low Backlash can be preserved at 1.5 arc-minutes or better at any ratio.

Durable components and quality craftsmanship ensure that low-backlash gearboxes will deliver years of dependable performance. The housings are manufactured from black anodized aluminum, with 303 stainless steel gears and shafts. These materials exhibit outstanding corrosion level of resistance, making SRX Series low backlash gearboxes perfect for harsh working environments.

low-backlash planetary gearboxes – compact and highly precise
The brand new planetary gearbox series from Ever-power includes the high-end gearbox lines GSD (flange gear), GSB (inline) and GSBL (angle gear) as well as the high-end economy GSN and GFE lines. Particularly suitable applications for the brand new range are those which place the highest demands on positioning accuracy, operating noises, operating smoothness, bending rigidity and transmitted torque. The planetary gears are made to meet the highest creation requirements – all lines are equipped with precision surface helical gearing, single-piece planetary carriers and complete needle bearings.
The EP high-end gearbox lines are constructed in a space-optimized, two-stage style. Because of the lower torque values, the input stage is definitely dimensionally smaller compared to the result stage. Its short style makes the GSD collection the ideal high-end gearbox for space limited applications. The low regular backlash of the GSD collection makes it an ideal fit for highly powerful applications where highest positioning and speed accuracy is necessary. The flange output generates highest torsional rigidity. For the lodging of especially high axial loads, taper roller bearings are elective in sizes with 90 mm diameter or higher. The GSB line stands for high performance in combination with low backlash and high precision. Its robust, one-piece housing permits a high gearbox rigidity and the absorption of high radial and axial loads. The angular gearboxes of the GSBL line provide same advantages as the EP range; the right angle form makes the GSBL collection an ideal match for all dynamic applications where space is limited.
The high-end economy lines combine powerful with economic efficiency: both lines are also built with helical ground gears, ensuring the very least noise level and smooth running. The full needle bearing offers been especially made to reach high torques that defeat the competition for devices of the same size. All planetary carriers are produced as a cage made from solid material. This increases noiseless operating characteristics while at the same time improving positioning accuracy and reducing backlash. Yet another shaft sealing ring ensures maximum dirt and splash water protection in accordance with protection course IP65 in all lines.
