 | THK World-Class KR Actuators -- Rigid, Accurate and Compact
The LM guide actuator model KR from THK provides high-rigidity, high-precision functionality and space saving. It is achieved by a nut block designed in a structure that integrates an LM rail having a highly rigid U-shaped cross-sectional form with the LM guide section.
The KR features a four-way equal load rating. The LM guide actuator can be operated in any position, which makes it ideal for loading in directions that are not fixed.

 | 25% more speed: Proven high-speed machining unit gets even faster
Specifically for metals with high cutting speed rates or small-diameter hole-drilling applications, the SUHNER SPINDLEmaster has been proven in thousands of installations. Now the BEX15 unit provides new speed options -- reliably up to the maximum speed limit. With an increase of 25 percent up to a permissible maximum spindle speed of 23,000 rpm, operations requiring higher spindle speeds can be accomplished more easily. This improvement is the result of a complete redesign of drive and spindle bearing components.

 | Redesigned jaw bucket is more productive for grab-and-go work
Bob Brooks, an expert in residential and commercial site preparation in the Pacific Northwest, says no other equipment accessory he has used compares to Parker's Helac PowerGrip Multi-Purpose Jaw Bucket when it comes to productivity. With PowerGrip, all the moving parts are fully enclosed, and there are no obstructions in the bucket shell (unlike competing units). It is equipped with a durable, enclosed rotary actuator hinge that offers 120 degrees of smooth jaw movement and constant clamping force.

 | World's smallest precision ball bearings
SPB-USA, located in Sarasota, FL, has the world's smallest ball bearings available. Manufactured in Japan by Sapporo Precision Inc. under the EZO-SPB brand name, each bearing has an inside shaft diameter of just .06 mm or .0236 in. and outside diameter of just 2.5 mm and a width of 1 mm. Each ball, and there are five in each race, is smaller than those found in a ballpoint pen, and each is precision ground to an exacting specification to ensure long life at operating speeds of between 142,000 rpm and 160,000 rpm. Applications include medical, aerospace, electro-mechanical, and packaging equipment.

 | PAEK polymer made specifically for 3D printing
VICTREX AM 200 filament has been specifically developed and optimized for additive manufacturing. The excellent mechanical properties of PAEK are in demand for high-performance parts. However, until now they were difficult to be fully realized in 3D-printed parts with existing choices such as PEEK and PEKK. For example, repurposing injection molding PEEK into filament fusion AM typically results in weak parts because of poor interlayer bonding. This new material is designed to address this weakness in printing PEEK. It has a higher Z-axis strength and is stronger in the XY direction, with a better fused filament forming (FFF) printing adaptability than the existing PAEK materials.

 | Self-supporting pliable hose
Flexaust Pliaduct is a 100% rigid, self-supporting PVC duct with a ribbon-lock construction that lets users expand the diameter up to 25% by twisting it, using both hands, to fit nozzles, funnels, or fittings. Ideal for spot-cooling applications, this wireless, flame-retardant duct can be reshaped and spliced together without tools and stays in place once bent.

 | Wow. Researchers claim new material can't be cut
Engineers in England at Durham University and their research partners have created what they say is the first manufactured, "non-cuttable" material. Their unlikely design inspirations? Grapefruit and abalone shell. In tests, the metallic foam material could not be cut by angle grinders, drills, or high-pressure water jets.

| | Videos+: Technologies and inspiration in action | Learn the benefits of Roller Pillow Blocks
The Roller Pillow Block from LEE Linear provides key performance benefits such as high load capacities, high speeds, and design compatibility, while also providing size interchangeability with industry-standard blocks. In contaminated environments, the roller bearings push particulates out of the way or roll seamlessly over them. Large rollers in the Roller Pillow Block system are well suited for long travel applications, minimizing vibration and providing smooth and quiet travel over joined shafts.

Watch NASA's Mars Curiosity rover take a selfie
This video shows Curiosity taking a selfie at the "Hutton" drill site on Feb. 26, 2020. A total of 86 images were taken and later stitched into a panorama (the final selfie). The video was taken with one of Curiosity's black and white Navigation Cameras on the rover's mast. It shows the Mars Hand Lens Imager (MAHLI) camera that Curiosity uses to take all its selfies. At the very end, you can see MAHLI's cover closing, which protects it from Martian dust.
