 | 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.

 | No Drip Spray Nozzles sanitize, clean, and cool
EXAIR's new 1/2 NPT No Drip External Mix Air Atomizing Spray Nozzles work in the same way the company's standard atomizing nozzles do, but have the added benefit of positively stopping liquid flow when compressed air is shut off. External Mix Air Atomizing Spray Nozzles have the highest flow rates and allow the air and liquid flow to be adjusted independently. They can be used on liquids above 300 centipoise. The patented No Drip design requires no additional air line to control the No Drip feature.

 | Carbon composite bellows springs for lightweighting and more
The Carbon Composite Bellows Spring (CCBS) from MW Industries is a system of carbon fiber elements that combine to work as a high-performance, lightweight, and design-flexible compression spring meant to replace conventional coil springs or metallic Belleville disc springs. It offers value through unique dynamic characteristics and unparalleled in-the-field design flexibility. A functional spring is made from several individual elements, paired in sets and joined to make a stack. The spring rate of the stack is determined by the number of elements, the base rate of each element, and their series or parallel orientation in the stack. Applications include motorsports, aerospace, outdoor recreation, general industry, and high-performance activities.
