products gears & gearBoxes micro gears for tiny applications
Micro gears with a module – the unit of gear tooth size – of up to 0.2 are available from igus. The gears are manufactured from iglidur semi-finished products, including iglidur A180 or iglidur A500, which are tribologically optimised (lubrication-free that assists free running). They therefore have particularly good properties in terms of friction, wear and strength, and are significantly lighter than metal gears, the company explains. “Producing teeth from gears that are hardly
visible to the naked eye is a skill that sets us apart from many competitors,” explained Rob Dumayne, drytech director at igus UK.
“Despite their tiny size, the teeth have excellent mechanical properties, enabling high-precision and reliable movements in precision mechanics.” The gears are suitable for numerous
applications in which finely tuned movements are required in the tightest of spaces – for example, for microscopes and other optical instruments such as miniature motors and micro-drives. igus also offers customer- specific production of these micro gears.

high performance gearboxes suit applications from robotics to 3d printing
Designed to provide a combination of unparalleled cost and high performance through enhanced torque output, precision and efficiency, the MD and MF planetary gearbox ranges from Apex Dynamics offer long lifetimes, high rigidity, and backlash in the range of 3 to 4 arc min (depending on the number of stages). Delivering high efficiency and high torque, these
include right-angled versions – MDK and MFK – and are provided in ratios from 4 (single stage) to 10,000 (4 stage). Available in
frame sizes 064 to 450, the MD and MDK gearboxes have rotary face output, with an alternative MDS version of the product available that incorporates the same set of features, as well as the choice of smooth input shaft or input shaft with keyway. The MF and MFK gearboxes have shaft output and are available in frame sizes from 060 to 240. Applications include: robotics, 3D printing,
industrial automation, pharmaceutical manufacturing, cutting and sealing systems, machine tooling, metal forming machinery, aerospace, textile production, laboratory automation, and more.

cycloidal gear range
Cycloidal gears from Nabtesco feature high dynamics and precision (max. hysteresis loss of 0.5 to 1 arcmin), minimal wear throughout the service life, outstanding shock resistance (up to 500% of the rated torque), and a high overload capacity (two to three times higher than that of planetary gears). This makes them the ideal basis for high-performance, reliable and efficient processes in the production industry, the company states. “Our cycloidal gears stand for efficiency, safety and
sustainability. They achieve pin-point positioning with a large safety margin, guarantee an above-average service life, and enable significant boosts in performance and efficiency,” said Daniel Obladen, head of sales general industries at Nabtesco Precision Europe. “Our roots are in robotics and automation, which explains our commitment to high quality. In 2024, Nabtesco’s focus on robotics will expand to
include general machine and plant engineering, in particular in machine tool manufacturing and medical technology. Nabtesco fulfils the typical requirements of these industries for precision, safety and efficiency with the Neco series. The servo gearboxes achieve high precision with a hysteresis loss of only 0.5 arc.min and feature an extremely robust design with double-bearing eccentric shafts and a bearing-mounted drive shaft. A high level of modularity and standardisation guarantee high availability. The simplicity approach reduces susceptibility to faults while optimising efficiency.

The SS700 Gen2 stainless steel speed reducer is the next generation of Boston Gear’s 700 Series Worm Gear Speed Reducer (
www.bostongear.com/ss700gen2), which has been used in the food and beverage industry for over 10 years. The NSF-certified SS700 Gen2 features an
improved Domed Crown curved design which eliminates virtually all pooling of liquids during washdowns. Its 316-grade stainless steel construction offers enhanced benefits in durability and hygiene; and its P69K-rated stainless steel enclosure is compliant with IEC 60529 and capable of withstanding washdown nozzle pressures up to 1450 psi at four inches without water ingress.

next generation stainless steel worm gear speed reducer launched New field-installable, FSMA and OSHA-compliant
shaft covers protect against potential food traps while eliminating safety risks associated with rotating elements. An optional tapered bushing eliminates the need for keys and keyways on the output shaft, removing opportunities for food traps, pathogen formation and sharp edge safety hazards. SS700 Gen2 Series speed reducers offer high energy efficiency along with the lowest operating temperatures
available. The series features larger output shaft bore sizes that enable the selection of smaller speed reducers, especially in low-torque or low-duty applications, providing the opportunity to downsize product selection and standardise conveyors throughout customers’ facilities.
