Igus said the plastic bearings will replace the re-circulating ball bearings, which need frequent re-calibration and maintenance. As a result, the DryLin R linear bearings can save up to US$36,000 per year.

Specifically utilised in the analyzer’s elevator unit, DryLin R linear bearings helps facilitate the up and down motion of both the furnace and cooling bath during the sample analysis control. It is also corrosion-resistant and self-lubricating, making it an ideal choice for barren environment where the analysers are being used.

Meanwhile, the company’s comprehensive line of DryLin R linear bearings as well as its guide systems, do not need external grease or oils, becoming an important feature for medical laboratories and helps keep the environment free from any contaminants.

Igus noted that its products are also necessary in determining the physical characteristics of solid and powder materials in areas like nanotechnology, cosmetics, polymer science and pharmacology. The chemisorptions and physisorption analyzers are designed to bring reliable and consistent determinations related to pore structure, active metals and surface area for R&D applications and quality controls.

Furthermore, the company will showcase this wide range of products at booth 234 in the upcoming SLAS 2012 conference and exhibition hosted by the Society for Laboratory Automation and Screening. The event will be held at the San Diego Convention Center in California from 4 to 8 February 2012, with the exhibition hall open from 6 to 7 February 2012.

With low cost versatile robots playing a vital role in cost-reduced/quality-upgraded small scale production, the new F5200N delivers huge flexibility in various dispensing operations, effectively making it ideally suited for a wide range of operations, such as form-in gaskets, potting, adhesives, filling and coating.

One of the major strengths of the F5200N gantry model is its ability to establish its own working area. This allows the system to be mounted on any type of work surface. In addition, the system can be used on any kind of platform that needs a gantry type mounting and open access beneath the robot. It can also be used in conveyor fed automation or integrated in work cells that operate as a slave robot, enabling users to make their very own workstation.

The company has emphasised that the robot comprises a teach-pendant, an articulated gantry and a control module. The working area of the F5200N measures 200 mm x 200 mm and features a resolution accuracy of 0.001 mm. Its teach pendant enables it to support windows compatible dispensing software, and allows it to store as well as retrieve a maximum of 100 programs or 400,000 points.

Accuracy and reliability feature strongly in the F5200, which also offers a resolution of 0.001mm/axis based on its micro-stepping motor controlled through USB/RS232 interface.

Offered in two versions, the first version, which is known as type EZS, has been specifically designed to drive screw drives using a rotating screw shaft. It will drive a screw nut that is usually attached to a linear slide. The screw is fitted by inserting it into the blind-hole hollow-shaft of the motor, and attaching it to a clamping set. In addition, screws measuring four diameters from 20 mm to 40 mm can also be used, depending on the size of the frame. The EZS motors have been equipped with special axial angular contact ball bearings, enabling it to effectively absorb high axial thrust.

The second version, which is known as type EZM, has been developed to drive screw drives using driven nuts. It features large flanged hollow shaft that can be used to directly drive flanged spindle nuts.

The new motors accomplish short lengths with the help of an orthocyclic tooth winding system that features a high copper fill factor, delivering around 80 percent more power compared to traditional winding. Both versions are offered in three lengths, two sizes and four spindle pitches (from 10 mm to 32 mm). The motors can also be supplied with liquid cooling and as brake motors. Forced cooling is offered as an option in the EZS models.

The SLP linear stage is also fitted with shaft support in the housing, while simplifying transition from traditional ball screw systems. Meanwhile, the addition of Nippon Pulse’s Linear Shaft Motor effectively makes the SLP stage a low-profile, high-precision product.

The company’s Linear Shaft Motor features three fundamental concepts. First, it is simple as it consists of only a forcer and a magnetic shaft. Second, the shaft motor is high-precision, providing sub-micron resolution. This is attributed to several factors, such as less heat generation, stiffness that is up to 100 times more than other linear motors, no Eddy currents and no cogging issues. Finally, the non-contact shaft motor also features a non-critical air-gap, eliminating variation in force over the device’s stroke.

Offering the highest force-to-volume ratio, the all-new SLP stage is an ideal solution for those working in space-restricted environments. Unlike other linear stage currently offered on the market, the single-axis linear stage series offers the smallest dead zone.

Offered in a choice of separate or integrated stepper motor/drive combinations, the all-new H series also comes in seven selectable travel ranges from 20 mm to 300 mm.

Aside from providing extended Z-axis travel with telescopically arranged linear axes, the modular design of the modules also offers a flexible mounting system for XYZ, XY and gantry systems.

The design of the actuator is based on an extruded profile housing that features T-slots, which facilitate optional limit switches, multi-axis actuator as well as customer fixtures. The fixed cover plate is specifically arranged to enable unrestricted carriage travel while offering added protection.

A linear guide bearing supports the carriage to provide it with maximum rigidity. The carriage also features a selection of precision or commercial grade lead screws to suit the customer’s various application performance needs and budget.

The series also offers a flexible coupling as well as anti-backlash nut arrangement. This ensures that the linear actuators would deliver high stiffness with repeatability at 0.1 microns for the precision grade option and 0.2 microns for the commercial grade option version.
