The Cross Roller Guide is a limited stroke linear guide that has precision rollers orthogonalized alternately. This product provides rigid yet supple linear motion and is particularly suitable for linear guidance where high rigidity and supple movement is demanded.

linear guideways provide a type of linear motion that utilizes re-circulating rolling elements between a profiled rail and a bearing block. The coefficient of friction on a linear guideway is only 1/50 compared to a traditional slide and are able to take loads in all directions. With these features, a linear guideway can achieve high precision and greatly enhanced moving accuracy. We offers multiple linear guideway series and each series features different options for sizes, loading capabilities, accuracies, and more.

Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile for a wide range of uses. The extrusion process makes the most of aluminums unique combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminum is one third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed with other metals.

it can be very difficult to fully center two shafts when connecting them together. Shaft deflection caused in operation of the machinery, thermal expansion of the shafts, warping of support plates over long periods of use, and wear of shaft bearings can also make it difficult to keep the shafts centered. The role of the coupling is to resolve these types of problems through the selection of the right coupling for the job. Miki pulley provides a wide range of coupling products not just for general purpose motors, but for everything from servo motors, which demand ultra-precise control, to engines, which generate high vibration and large shocks. types of couplings and bushes: sfc (flexible coupling), sfs (flexible coupling), sfm (flexible coupling), psl-k (etp bushings), psl-g (etp bushings), starflex couplings

ballscrews, also called a ball bearing screws, recirculating ballscrews, etc., consist of a screw spindle and a nut integrated with balls and the balls return mechanism, return tubes or return caps. Ballscrews are the most common type of screws used in industrial machinery and precision machines. The primary function of a ballscrew is to convert rotary motion to linear motion or torque to thrust, and vice versa, with the features of high accuracy, reversibility and efficiency. We provides a wide range of ballscrews to satisfy your special requirements.the combination of state-of-the-art machining technology, manufacturing experiences, and engineering expertise makes our ballscrew users high-tech winners. We uses precise procedures to create exact groove profiles, either by grinding or precision rolling. Accurate heat treatment is also used to ensure the hardness of our ballscrews. These result in maximum load capacity and service life.our precision ballscrews provide the most smooth and accurate movement, together with low drive torque, high stiffness and quiet motion with predictable lengthened service life. Our rolled ballscrews also provide smooth movement and long life for general applications with less precision in lower price. Our modern facilities, highly skilled engineers, quality manufacturing and assembly processes, and uses quality materials to meet your special requirements.it is our pleasure to provide you with the technical information and selection procedure to choose the right ballscrews for your applications through this catalogue.

Rack lengths up to 3.00 meters are available standard, with unlimited travels lengths possible by mounting segments end-to-end. Quality levels available include soft, induction-hardened, quenched & tempered and hardened & ground (up to agma 12+ and din 4). Typical delivery time for these standard components is 2 to 3 weeks, which is ideal for oem's requiring just-in-time delivery schedules. Special and/or modified components are always possible - please consult the factory. For harsh environments, stainless steel rack & pinions are available, as well as coatings such as black oxide and chromium (armoloy ).

linear actuators are compact, lightweight and highly flexible products that can be found in a wide range of applications. Linear actuators utilize a gear system that is connected to a screw and is driven by a motor. As the motor operates, the gearing translates to the screw shaft, converting rotary motion into linear motion.we can supply a complete actuator solution that includes actuators, controllers and keypads for a single or multiple axis system. We offers a wide range of linear actuator designs to fit your specific application.

For decades Frictionless tables have been renowned for the highest degree of accuracy, reliability and the ultimate in operating characteristics. Preloaded anti-friction guideways make these tables absolutely playfree.

Linear Bearings enable high precision linear motions on round shafts by utilizing endlessly recirculating balls. The patented recirculation curve enables Linear Bearing to sustain heavy loads with low noise and high stiffness. Our diverse lines of Linear Bearings perform under almost any environmental conditions and load capacities to satisfy a wide range of applications.

Our track roller guides are ideally suited for high movement speeds and they also do their work in harsh environments. The basis of each guide is a standard our profile as carrier profile. In addition a suitable clamp profile and the guide rods are selected. The carriage with guide rollers and carrier plate is configured to meet your requirements.

lead screw a leadscrew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion. C45 and a2 stainless steel were chosen because in addition to their natural qualities as good construction materials, after rolling they give very good surface hardness and finish on the thread sides. A4 stainless steel also has excellent corrosion resistance. C15 is an excellent quality - price compromise. After rolling, c15 has surface hardness of approximately 160/180 hb, c45 approximately 250 hb, a2 stainless approximately 260 hb and a4 stainless approximately 280 hb while roughness is less than 1 m ra for all. These two features are decisive factors for qualitative appraisal of trapezoidal screws because they give very small friction coefficients, much lower than those obtainable with machined screws where other conditions such as speed, load and lubrication are equal. Our trapezoidal screws with bronze nuts give traversing systems with efficiency, and quietness the compared with coupling with machined screws because of the low friction coefficient the amount of heat generated during movement is limited with resulting smaller nut heating . Nut life is also increased. We make nuts with 10 kinds of material to better meet the various requirements.
