NIA linear actuators from Nook Industries

Nook Industries (www.nookindustries.com) is proud to introduce the new NIA ACME and Ball Screw Series Linear Actuators that provide compact size configuration and improved IP65 protection options against solid (airborne, dust particles, etc.) and liquid (water spray, rain, etc.) elements. The product is a cost-efficient series designed for light-duty outdoor/indoor applications, including aggregate/agriculture (packaging, dampers in rock quarries, etc.), amongst others.

All of the series are designed to deliver International Protection (IP) rating against levels of water/dust intrusion as an optional enhanced IP65 and standard IP54 protection class. The high-IP ratings were achieved through the use of several design elements, which include powder metallurgy gears, steel extension tube and aluminum alloy housing.

The new series features a standard 110/115/230 VAC single-phase split capacitive motor, delivering a 25-percent duty cycle, as well as an external capacitor. Other standard performance characteristics for ACME and Ball Screw versions include stroke lengths from 4in to 24in, working temperature of -26°C to +65°C, dynamic load capacity of 1,500lbs and less, overload protection by clutch, and self-locking. Adjustable limit switches and optional potentiometer feedback are also available to extend the added-value for unique applications on the two versions.

Nook Industries also offers its ND8 Ball Screw Series as a 12/24V DC Motor option that can deliver similar key design variables with the addition of stroke length of 100mm to 600mm and 65mm/sec maximum speed, with no back driving.

New Thomson T60 Precision Range expands Heason Technology’s Linear Actuator Range

Heason Technology (www.heason.com) has announced that it added the latest Thomson T60 precision ballscrew linear actuator to the company’s wide array of positioning solutions. The T60 is a compact and powerful push-rod style actuator with a 38mm diameter hard chromed steel extension tube and 75mmx60mm profile housing for acceleration to 8m/sec2, speeds to 300mm/sec, selectable travel up to 1500mm and direct force to 1000N.

Its simple and yet effective design offers a long life, low-maintenance linear positioning with efficiency, precision and control that will outperform hydraulic and pneumatic cylinder actuators in a very similar format.

The unit has IP65 rate and is designed for harsh environments. The T60 is based on the same successful design of larger T130 and T90 Precision Linear Actuator (PLA) models from Thomson (www.thomsonlinear.com) which both suit a wide range of industrial applications from pharmaceutical manufacture to electronics production, as well as from pick and place systems to packaging automation.

The Thomson T60 is available in the market with a choice of 25mm diameter precision ballscrews with leads of 50mm, 25mm, 10mm and 5mm repeatability with a pre-loaded single nut arrangement for backlash. Its maximum input speed of 3000rpm allows comprehensive choice of motor technologies from speed controlled stepper motors, DC motors or full positioning servo motors. A wide range of accessories also allow side-mount options complete with belt drive arrangements or inline mounting with couplings.

New 28 mm Diameter Ball Screw Per JIS Standard

BURLINGTON, MA — Steinmeyer, Inc. announced a new addition to its line of precision ball screws – a 28 mm diameter screw with 12 mm pitch. Normally our product line is guided by the DIN standard which specifies shaft diameters of 20, 25, 32, 40 mm, etc.

This new 28 mm diameter product was designed as a size compatible with the JIS standard. The ball screw is supplied with choice of two nut styles: single nut with flange series 1416; or double nut with flange series 1516. The ball nut is normally provided preloaded for zero backlash. The screw shaft is precision ground and offered in accuracy grades T0 to T5. Threaded length, journal details and overall length are per customer specification.

High Lead Miniature Ball Screw from Steinmeyer

BURLINGTON, MA — Steinmeyer, Inc. announced a new addition to its extensive line of precision miniature screws – a 5 mm diameter ball screw with 3 mm pitch. This high lead miniature screw is the perfect solution in applications for the aerospace arena, such as fin actuators. Maximum speed is 4500 rpm with a dynamic load capacity of 590 newtons. The ball screw is supplied with our series 2422 ball nut which can be modified to include trunnion supports as shown in the photo. The screw shaft is precision ground and offered in accuracy grades T0 to T5. Available with either zero backlash, using oversize balls, or minimum axial play of less than 20 microns, the ball screw is offered in standard lengths with machined journals as well as custom configurations. All parts are manufactured from certified materials.

Used in aerospace actuators around the globe, the ball screws offer internal ball return for smoother motion, higher speeds and very compact nut bodies.

New Miniature Ball Screw Series from Steinmeyer

BURLINGTON, MA — Steinmeyer, Inc. has announced a new product to its extensive line of miniature ball screws. These 5mm diameter screws are the perfect solution in applications such as micromanipulators, miniature robotics and compact actuators.

Available in four nut styles, series 1112 single nut with connecting thread without wipers, series 1412 is a single nut with double flange and wipers on both ends, series 1214 is a cylindrical nut without wipers and series 2422 is our “quiet line” series, with a single nut that uses end-cap ball returns manufactured from plastic rather than metal tubes, making the screw virtually noiseless. All are available with leads ranging from 0.5 mm-3 mm and offer a maximum speed of 4500 RPM.

Left-Handed Ball Screws Level the Playing Field

Why in the world would anyone need a ball screw with a left-handed thread?  Why not simply reverse the program and drive the device in the opposite direction?  Unfortunately, this may not always be the best solution. Several industrial applications require a left-handed ball screw to help resolve high-precision programming requirements and reduce the number of needed expensive components.  

For example, imagine a system designed with two ball screws; one right-handed and the other left-handed, with each unit positioned on either side of one drive motor moving in opposite directions.  This configuration is less expensive and much more practical because only one motor is required and there is no need to synchronize two separate right-handed ball screw systems driven with two servo or stepper motors. 

Another application comprises two units placed in parallel and connected with a belt drive and two pulleys.  This arrangement contains one motor that drives two linear motion mechanisms in opposite directions.  

Left-handed ball screws can be made to suit most current applications in machine building, assembly system design, and other factory automation integrations. For example, they may be specified with a reversed-direction flange nut, key grooves or flat ends, unfinished support sides, and grease for cleanroom and food processing applications. In addition, ball screws can be designed for many custom applications and delivered in as little as eight days.
