Precision Planetary Gearboxes

GSA

GSA planetary gearboxes are high quality, economically priced gear units, with a design life that doubles the specifications from their closest competitor. They are suitable for both continuous or intermittent operation, in applications where extremely low backlash is not fundamental. Unlike market standard gearboxes that employ nitrided gears, GS gearboxes use gears made of high strength alloy steels, carburized, case hardened and ground, offering greater reliability and longer service life. Optionally available with food grade lubrication.

GSB

GSB gearboxes improve upon the GSA design by incorporating reinforced output bearings, that more than double the output shaft's radial load capacity, while still offering great value.

GSD

GSD gearboxes improve upon the GSA design by employing significantly thicker output shafts, that allow for greater torque transmission, without breaking the bank.

GSE

GSE gearboxes improve upon the GSD design by offering a more compact and dynamic solution when high transmission ratios, that mandate two stage designs, are required.

GSAH

GSAH are hollow output shaft gearboxes while keeping the GSA gearboxes' impressive specifications. This shortens the drivetrain, and thus results in a more compact and dynamic machine.

GSDH

GSDH are hollow output shaft gearboxes that offer higher torque transmission capacity and tougher design than GSAH gearboxes thanks for their steel output flange.

GE planetary gearboxes are high quality, economically priced gear units, designed to work with servomotors in either continuous or intermittent operation, in applications where extremely low backlash is not fundamental.

SGS

SGS planetary gearboxes have excellent torque transmission and output shaft radial load capacity thanks to their reinforced output shaft, steel output flange and tapered roller output bearings. They're ideal for rack&pinion transmissions, specially when employing helical gearing. Unlike market standard gearboxes that employ nitrided gears, SGS gearboxes use gears made of high strength alloy steels, carburized, case hardened and ground, offering greater reliability and longer service life. Optionally available with food grade lubrication.

FG Planetary Gearboxes' main selling points are their ISO-9409 flange and their very compact nature. This design allows directly attaching a pulley, dial plate, pinion, AGV wheel, etc. These elements are perfectly centered and very securely attached, resulting in a final assembly that is extremely short. They're used in machines that require highly accurate positioning and highly dynamic cycles. Additionally, FG gearboxes offer a very high torsional rigidity, that can reach up to 5 times the torsional rigidity of solid shaft gearboxes of equivalent size.

SG High Precision

High precision SG planetary gearboxes are high quality gear units with a combination of innovation and years of experience. SG planetary gearboxes are designed to work with servomotors in machines requiring high accuracy positioning.

SGM High Precision

SGM gearboxes improve on the SG design by employing 4 planet gears in the last stage. This increases torque transmission capacity but only allows ratios multiple of 4. They otherwise maintain the high precision characteristic of the SG design.

SGH High Precision

SGM gearboxes improve on the SG design by employing 6 planet gears in the last stage. This substantially increases torque transmission capacity but only allows ratios multiple of 3. They otherwise maintain the high precision characteristic of the SG design.

Right Angle Precision Gearboxes

SVS

Where the highest precision isn't required, SVS right angle gearboxes are the right choice. It offers excellent value while being precise and reliable. Its compact design makes it the lightest in its class, and it has an extremely smooth operation. For both applications that have high cyclic rates, and for continuous operations, SVS gearboxes are a perfect match, and one that won't break the bank too.

SQS

SQS gearboxes are an evolution of the SVS design with a monobloc housing that includes feet on every face. It offers better heat dissipation, and higher toughness.

MA Right Angle gearboxes shine thanks to their high precision and high torque capacity (up to 1680 Nm) contained in a compact aluminum housing. They've been designed with the latest advancements in precision gear engineering, they offer the highest specifications when it comes to motion control applications that require highly repeatable positioning.

MQ Precision Right Angle Gearboxes

MQ right angle worm servogearboxes have been specifically developed for the most demanding servo-applications where accuracy, stiffness, and reliability are critical. MQ gearboxes provide precise rotary motion for both highly dynamic cyclical and speed control servo applications. Output options include single shaft, dual shafts, hollow shaft with keyway and hollow shaft with shrink disc. The backlash levels allow it to satisfy a variety of applications.

Heavy Duty Gearboxes

S Heavy Duty Planetary Gearbox

PL Planetary Gearboxes are used in machines that require high torque, heavy duty cycles, and variable speeds. Compared to other industrial gearboxes, they have higher torque density, smaller sizes, and lighter weights. Their high torque density is due to the load being split between multiple planetary gears, allowing for more efficient energy transfer, lower vibrations, longer service life, and higher efficiency (up to 98% per stage). They can be driven directly through a servomotor or an IEC motor, or alternatively through a solid input shaft.

R Helical gear units

R Series helical gear units are heavy duty gearboxes with inline input and output designed to meet the requirements of machines that operate in the most demanding industrial environments. Their gear train is employs one or more helical gear stages, and the gears are case hardened and ground. Gears have been designed following ISO and DIN standards. The cast iron housing has been designed using FEM techniques. This design is extremely rugged, offers high reliability, and has up to 98% efficiency. It can be flange or foot mounted.

F Parallel-Shaft Helical Gear Units

F series parallel-shaft helical gear units are heavy duty gearboxes whose input and output shafts are parallel. They've been designed to operate in the most demanding industrial environments. Their gear train is employs one or more helical gear stages, and the gears are case hardened and ground. Gears have been designed following ISO and DIN standards. The cast iron housing has been designed using FEM techniques. This design is extremely rugged, offers high reliability, and has up to 98% efficiency. It can be flange or foot mounted. Output torque ranges between 50 Nm and 10800 Nm, and they accept both servomotors and IEC motors.

Zero Backlash Rotary Actuators

SRT-M

The SRT-M series is composed of fully programmable rotary actuators that position large loads with remarkable accuracy. Their zero-backlash transmission allows for full synchronization with robots or other digital peripherals. Their large central opening allows engineers create more compact and higher performing designs, that were previously unthinkable.
