    Features

    • A gearhead utilizing the industrial robot industry-proven Precision Reduction Gear RV
    • Shorten cycle times with high speed rotation
    • Compact size reduces total height of machine
    • Hollow shaft for wiring
    • Compatible with all major servo motors

    • Pre-lubricated
    • Easy oil changing

    Advantages over Cam Indexers

    One of the most noticeable advantages with the RS-50A turntable gearbox is the ability for infinite positionability. Compared to fixed-stop index tables, a servo motor paired with the RS-50A will allow for precise positioning at any angle. This increases flexibility and allows the same unit to be used for different applications.

    Another major advantage of the RS-50A is there is no calibration needed. After initial installation, the application is essentially maintenance free. In comparison, Cam indexers rely on sliding friction, whereas Nabtesco Indexers rely on rolling friction; allowing significantly greater efficiencies.

    Finally, we understand how important projects and lead times are to our customers. This is why the RS-50A is ready to ship from our local stock. This beats out average shipping times against cam indexers by weeks.

    Shorten Cycle Times

    The RS-50A utilizes our hollow shaft RV gearbox with its large torque capacity. This allows for large loads to be positioned both quickly and precisely. Able to withstand the large torques that occur when a load is accelerated/decelerated, this translates to shorter cycle times for the user. For example: 180 deg in 1 sec, for a load with 10 kgm2 moment of inertia.

    We offer the RS-50A with reduction ratios ranging from 65.4:1 to 163.5:1. This gives the customer the flexibility to choose a product that fits best for their intended application.

    Easy to Use

    The RS-50A turntable gearhead comes pre-lubricated with RV Oil SB150, and is completely sealed. A variety of motor flanges and input splines are available that allow for easy mounting of all major servo motors.

    This saves time and hassle associated with the gear-motor interface. Dowel pin holes are also provided on the output face and installation surface for simple and efficient re positioning of any attached fixtures (and also the unit itself).

    Release Date

    With floods of interest around our newest index table gearbox, the RS-50a will to be ready to ship in August 2019.

  • 8 HIGH RATIO SOLUTIONS YOU DIDN'T KNOW WE HAD
    Nabtesco understands the benefits of having a broad product line of gearboxes with varying ratios....

  • WHY HIGH RATIO?

    If you’ve ever ridden a bike with the ability to shift gears, then you understand the basic benefits of having a higher ratio in a drive train. If you are riding on a flat road, a low gear ratio will produce the highest speed with the least amount of effort. When the road comes to an incline, you may need to change gears to a higher ratio which allows you to overcome the added strain that is brought on by the slope of the road.

    The same reasoning applies to manufacturing. If you use a high ratio gearbox, you can drive a machine with a smaller motor. This decreases cost for the drive and it also allows for a more cost-efficient machine for the end user as the smaller motor consumes less energy. A lower ratio will allow a higher speed but will require more torque from the motor.

    OUR SOLUTIONS

    Nabtesco understands the benefits of having a broad product line of gearboxes with varying ratios. A robot or positioner will typically require a high torque, low speed drive. A rack and pinion or belt drive design will typically need a higher speed gearbox with less torque. We have a range of ratios from 11:1 up to 400:1 and greater, to accommodate your drive requirements.

    RV-N Series Gear Reducer
    RV-N Series Gear Reducer

    Our standard product typically takes a cycloidal gear and multiplies it with a spur gear stage. This allows us to keep the exterior dimensions of the gearbox the same, with only a few variances within the product, making it easy to produce a variety of ratios with minimal changes within our product. It also allows for some of the highest ratios on the market within a very small size envelope.

    WHAT WE HAVE

    If you are looking for a ratio higher than what we have in our catalogs, most customers add another gearbox to increase this value. This works well, but it also increases the size of the design and the end cost to our customer. So, we are coming up with even higher ratio solutions for these applications. Most of these are not published in our catalogs and we keep limited stock of these products, so please contact your distributor for availability.

    As these products are not published in our catalogs, we are including some of them below to make you more aware of our capabilities. We are continuing to increase these designs, so if you don’t see what you need, please contact us for more information.

    High Ratio examples :

    C series (hollow shaft)
    Model Ratio Allowable acceleration torque
    320C-378.07 378.07 : 1 7,840 Nm
    500C-400.04 400.04 : 1 12,250 Nm
    900C-203.98 203.98 : 1 22,050 Nm
    1200C-201 201 : 1 29,400 Nm
    N series (solid shaft)

  • INTRODUCING THE RH N KITS

    One of our goals in 2019 is to make the customer experience more seamless. That is why we are introducing our new pre-engineered solution in the form of the RH-N Kits.

    RH-N Kits utilize our newest series of gearboxes, the RV-N Series. The RV-N Series is up to 20% smaller and 30% lighter than our original RV-E series. The RH-N Kit marries the RV-N gearbox, resulting in a housed component for a plug and play solution that cuts down on engineering time, lead time and the installation process. The RH-N directly bolts onto your servo motor without the need of additional components.

    SO, what makes up an RH-N Kit?

    • Any RV-N Series Gearbox
    • Input Pinion
    • RH-N Middle Flange
    • RH-N Motor Flange
    • Oil Seals
    • O Rings
    • Fasteners

    RH N Kit expanded

    WHY USE THE RH-N KIT?

    The RH-N has been adapted to most servo motors for your design/application. Nabtesco’s value added solution will work on all RV-N series gear reducers with any standard ratios.

    There is no machining required of the input pinion, you simply bolt it together. No more requirements to manufacture and machine motor plates and housings. Saving time and Engineering hours is the value-added advantages of the RH-N kits.

    All you have to do is install it!

    REDUCING LEAD TIMES AND THE BUILD PROCESS?

    RH-N KitAll RH-N Kits will be designed and manufactured right here in the USA. Nabtesco will have a 2-week lead time on all none stocked items, in an effort to reduce the customers project lead time. As we mentioned in our annual distributor meeting, one of our main objectives for 2019 is to increase stock levels to allow for JIT delivery. Nabtesco Motion Control, Inc. has increased our stock levels for 2019, thus allowing for a 2-week delivery in most cases.

    Nabtesco is offering optional complete assembly of the RH-N Kit:

    At our facility, we are capable to make various configurations out of the RV-N gearbox body. To make life easier, we also will offer to fully assemble the RH-N together to the RV-N gearbox of the customer’s choice. This installation process will include a completed assembly of the kit and gearbox excluding grease. All oil seals will be installed properly and all bolts will be torqued to the proper specks to complete the assembly process.

    All finished assemblies will be boxed and secured for transportation to end user.

    (Note) The end user will be required to install the proper grease or oil levels from one of the Nabtesco lubricant products: RV-oil, RV Grease, Vigo Grease or Molly White.

    ANOTHER METHOD OF SHIPPING

    We can also send you the component pieces of the kit to assemble yourselves. Depending on the application, this may allow greater flexibility to the end user.

    COMPARISON BETWEEN RD2 AND RHN SERIES

    Our RD2-S & RD2-R use the RV-E series, and the size stops at 320 (rated torque). With the RV-N series, the size goes up to 900 (rated torque). We plan to see a migration towards the RV-N Series, and in turn the RH-N Kits. The reasoning behind this is 2-fold.

    Firstly, our RV-N series gearboxes are smaller, lighter and more powerful than our traditional RV-E series. Secondly, as a customer you’re going to receive everything you need to put it together.

    ANY QUESTIONS?

    We are dedicated to making this process as seamless as possible. If you have any questions about our RH-N Kits, the process, or other topics we have missed; we want to hear from you.

    Is the installation process something your customers would see as valuable? We want to know!

    Please feel free to respond to this email as it will go directly to our sales team, or reach out them directly. You will find their emails attached at the bottom of the newsletter.

    We are looking forward to a great year in 2019 working together!
