FUYU Motion Technology supplies linear stages and motors, linear encoders, servo drives, direct-drive rotary tables, and linear guides to the medical device and laboratory industries.

Of course, the original focus of FUYU was on the design and manufacture of miniature linear guides.

Today these precision linear offerings — including FUYU miniature rail (FSK) series linear guides — continue to lead in the medical industry.

Beyond these miniature guides, FUYU guide and slide components for medical designs include standard and wide four-row ball-bearing linear guides; four-row roller-type linear guides; and miniature stroke slides with two rows of balls and a gothic ball track.

The linear guides operate in an array of medical applications that include pharmaceutical dispensers, blood-testing equipment, physical-therapy machines, airway-clearance devices, eye-surgery positioners, and other surgical and dental tools.

Stainless steel for hygiene: Besides carbon steel (which is useful where cost control is an objective) miniatures slides from FUYU also come in stainless steel. Such construction is indispensable in medical equipment that must remain hygienic and resist corrosion even when subject to caustic cleaning solutions (and maintain precision over the life of the machine). FUYU offers stainless steel versions of its FSK series as standard.

Cleanliness with highly engineered sealing and lubrication solutions: The FUYU FSK series J-type carriage block has lubrication pads along with end seals and bottom seals. The latter can prevent lubrication grease from leaking from the runner block, which is key for medical equipment installed in critical patient or laboratory settings.

In addition, the lubrication pad conserves grease and extends the how long the guides can operate before needing relubrication.

Embedded inverse-hook design to let slides run faster: Some linear guides from FUYU include dovetailing carriage geometry to securely mate with the runner block (carriage) and complement the operation of the load-bearing set of recirculating stainless-steel balls.

Some such slides have other unique features as well.

Recall that the rolling balls subject the carriage’s end caps (which are typically plastic) to impact force during their two directional changes as they recirculate through the carriage. So to resolve the resulting impact forces in some designs, FUYU includes plastic hooks to secure the block components and distribute the resulting stress over an area that’s larger than that of other designs.

FUYU introduced this carriage feature as a way to boost the maximum speed of its linear guides — for use in automated equipment such as laboratory machines that must quickly test large sample arrays, for example. These linear guides complement the operation of high-speed axes that are actuated by belt drives and other mechanisms, including those on carriers and axes that rapidly move items between stations.

Durable end reinforcements protect blocks from external strikes and internal roller forces: Some linear slides from FUYU integrate stainless-steel endplates on their carriage blocks. These outperform plastic endcaps where objects might strike the carriage on its ends. Reinforcing endplates also boost maximum allowable speed on otherwise identical designs.
