The World's First -- and Best -- Linear Motion Guides THK's original technology is behind the smooth and silent movement of the "Linear Motion System." The LM Guide is our major product that put the rolling of the linear motion part into practical use for the first time in the world. This improves the accuracy, rigidity, energy saving, velocity, productivity, and service life of the machine. THK offers a full support system from the beginning design phase throughout the maintenance, and follow-up service.

Download Photo Etching Precision Parts Guide This Tech-Etch guide describes how photo etching produces prototype quantities and large production runs of precision parts for many mechanical and electrical applications, without the high cost and long lead times of hard tooling. Custom metal parts from .0005" thick and up are produced with intricate patterns, precise tolerances and burr-free edges, in addition to exact repeatability. By combining photo etching for blanking with inexpensive or universal tooling for forming, Tech-Etch produces complex designs and shapes. Get the guide (no registration required).

Cross roller ring can swing the loads Because it has orthogonally arranged cylindrical rollers, the cross roller ring from THK is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90-deg V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including radial, axial, and moment loads. This component is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments, and IC manufacturing machines. Available in several rotation configurations including inner/outer ring, inner ring only, and outer ring only. And now a new micro cross roller ring is perfect to handle smaller applications. Learn more about THK cross roller rings. Learn about the new Micro Cross Roller Ring RAU.

12 principles of modern military leadership: Part 2 Leadership is paramount to the success of any army -- and any organization in general. Leaders not only make life and death decisions sometimes, but directly control the climate and quality of life of their subordinates. But what is the real definition of leadership? Capt. Ron Roberts of the U.S. Army's Asymmetric Warfare Group discusses 12 fundamental leadership principles, as well as several educational and inspirational historical examples. How much do they apply to what you do?

Laminating precision parts with polyimide film for insulation and spacing When a dielectric is required to maintain accurate finger spacing or for insulation, Tech-Etch can laminate materials such as polyimide. Polyimide can be die-cut and directly bonded in place or full sheet laminated and then photo etched for extremely accurate positioning. Parts can be formed after lamination. Tech-Etch also photo etches polyimide film into flat parts including non-conductive washers, screens, gaskets, insulation layers, and liners. For flexible circuits, the coverlay is the insulating layer of polyimide placed over the exposed conductors. Polyimide is ideal for corrosive environments and also exhibits excellent physical, chemical, and electrical properties over a wide temperature range. Tech-Etch offers complete prototype-to-production facilities for etching extremely intricate parts. Download a capabilities brochure (no registration required).

Replace traditional fasteners: 50+ retaining ring applications The benefits of a Rotor Clip Retaining Ring are simple: The ring is made from less material than traditional fasteners, eliminating machined shoulders, threads, cover plates, and heat-formed studs -- so you save. Using a retaining ring to fasten your assembly instead of a traditional fastener not only reduces your costs, but also saves the environment. Fewer parts and less material means cost savings for you and less waste for the planet. This quality part offers lot traceability. Want to know what you can do with a Rotor Clip Retaining Ring?

Polyimide heater kit -- tons of uses The Polyimide heater kit from Omega Engineering contains thin and flexible heaters with adhesive backing to conform to practically any flat or curved surface. With 15 different shapes, this kit can suit almost any application. Heater configurations are outlined on a 0.3-m x 0.3-m (1-ft x 1-ft) sheet, with line markings for easy selection and cutout. When used in combination, these heaters can provide a number of resistances and wattages. Leads can be soldered on or connected with alligator clips. Typical applications include: aerospace, analytical equipment, tooling, commercial equipment, agriculture, packaging, and material handling.

Collect and understand vibration condition data Vibration monitoring is one of the most effective ways to detect potential equipment failures before they cause downtime. However, vibration analysis is complex, and it can be cost prohibitive to place sensors on noncritical assets. The new, wireless Fluke 3561 FC Vibration Sensor allows maintenance teams to improve uptime by adding remote, continuous vibration monitoring to virtually any rotating equipment. With a frequency range of 10 to 1,000 hertz, the 3561 FC detects and notifies users of conditional changes caused by critical faults like imbalance, misalignment, looseness, and bearing wear, providing warning of impending equipment failure.

World's most wear-resistant metal alloy engineered at Sandia Labs If you're ever unlucky enough to have a car with metal tires, you might consider a set made from a new alloy engineered at Sandia National Laboratories. You could skid -- not drive, skid -- around the Earth's equator 500 times before wearing out the tread. Sandia's materials science team has engineered a special alloy believed to be the most wear-resistant metal in the world.

| Torque tools go out of calibration. Fix them. | |
Using a quality torque tester makes a safer world through accuracy and precision. Torque testers can be used for quick tools tests on the line or in the lab to determine whether the tools are holding a given setting. The Mountz TorqueLab LTT is a laboratory-grade instrument designed for testing and monitoring torque applications and is commonly used for quality control, R&D, and calibration applications. It tests or calibrates hand-torque screwdrivers, electric screwdrivers, pneumatic screwdrivers, and torque wrenches. It features EZ-Plug & Play technology, which is an auto-recognition system with Mountz torque sensors.
