Its open type housing allows a support from below so that a deflection of the shaft is minimized for high loading or long-stroke applications. The outer cylinder of this standard type slide bush is made of bearing steel and resin. The seals prevent dust from entering the slide bush in order to guarantee motion accuracy, which extends its life. Twin slide bushings with seals at both ends were used. Since the contact areas between the ball elements and the precision ground raceway surface of the slide bush were minimized, the slide bush provided low friction compared to other linear motion mechanisms. To ensure fast, smooth operation, SMI chose a slide bush with raceway surfaces that are precision ground. SMI attached aluminum pillowblock slide bush components to a custom machined metal plate. It was prompted by a client's need for an inexpensive, easy to maintain system that would be used for loading material into a printing system. SMI created a simple, reliable X/Y system. Soon they found slide bush components with unique characteristics that ensured simple motion control solutions would be reliable and easy to maintain. SMI started to experiment with the linear motion products that it carried. New ideas flowed in the wake of these added capabilities. This required a more complex level of service requiring expansion of its facilities to accommodate machine tools and skilled technicians. SMI combines components into assemblies for its clients. The center of the Simple Slide has been modified with a 'VEE' groove to allow the material being measured to accurately nest for measurement. The LDMD can be mounted as a fixed unit using the Simple Slide base mounting holes or it can be attached to any rigid structure with wheels for a transportable measuring device. 001' and any length up to 110' (currently). The Linear Digital Measuring Device (LDMD) is capable of accuracies up to +/. The DRO display can be mounted to the carriage itself or fixed in a different location for convenience and protection. The carriage is then moved into position to touch off on the end of the shaft (or whatever is being measured) and the length reading is read directly from the DRO. The material to be measured is laid flat in the Simple Slide's base and butted against an end stop. By sliding the carriage all the way to the end, the DRO is reset to 'zero.' Then, as the carriage is moved out, the DRO consistently reads where the carriage is relative to that end plate. This was accomplished by adding a Digital Read Out (DRO). SMI combined a half-inch slide bush with a shaft (SMI calls the combination a 'Simple Slide'), and incorporated a linear scale. Its floating load plate adjusts clearance. TOPBALL's floating wiper seal makes this unrestricted self-alignment possible. To construct the measuring device, they used the open pillowblock slide bush type TW8UU, which is part of NB's TOPBALL self-aligning slide bush line. Often the lengths were much longer than the typical vernier caliper could measure at a reasonable cost. The materials being measured could be round, flat or square material. (SMI), a linear motion components distributor, set up its own machine shop, and encountered the need to measure long materials, such as shafts, right at the shop floor - a need they shared with many of their customers.

Steel and resin slide bush products in NB Corporation's GM series.ДЄ self-aligning slide bush line called TOPBALL. Resin seals are used for GM series.ДЄ few of the steel slide bush products in NB Corporation's SM, KB and SW series. To reduce noise, the ball return section is made of resin. The GM slide bush uses resin subparts - achieving an overall weight reduction of 30-50% compared with the standard slide bush. The steel retainer is made of one plate (seamless).Д¬utaway of GM slide bush type. The retainer is available in steel (stainless steel for anti-corrosion), and resin for low acoustic operation. Cutaway of standard type slide bush which has an outer cylinder made of bearing steel or, if anti-corrosion type, the outer cylinder is made of Martensitic stainless steel.
