Identification Number and Specification xample of an Identification Number The specifications of the series are indicated by the identification number. Indicate the identification number, consisting of a model, dimensions, a part, a classification symbol, and any supplemental s for each specification to apply.

Long term maintenance free For details P The built-in "-Lube", the capillary lubricating element, in the ball circulation pipes of the slide unit makes it long term maintenance free. Lubrication oil is continuously supplied to the surface of rolling elements by surface tension in the contact of the capillary lubricating element surface and rolling elements. ost performance Preserving the basic performance of -Lube Linear Way ML as is, lower cost has been achieved by reviewing the structure including the ball recirculation part. all retained type for easy operation The slide unit incorporates the ball retaining band, which prevents the ball from dropping down when the slide unit is removed from the track rail. This safety structure brings you an easy operation to the machines/equipment. Stainless steel selections for excellent corrosion resistance For details P. -1 5Stainless steel highly corrosion-resistant is used as the basic specification, so that the products are suitable for applications where rust prevention oil is not preferred, such as in cleanroom environment. 1 1=0.097inch 2

4 Preload Precaution for Use Preload for the series is adjusted to have subtle clearance or minimal amount of preload. Lubrication Lithium-soap base grease (MULTMP PS No.2 [KYOO YUSI O., LT.]) is pre-packed in series. Additionally, series has -Lube placed in the recirculation part of balls, so that the interval for reapplicating lubricant can be extended and maintenance works such as grease job can be reduced significantly. series have an oil hole. (See Table 5) edicated supplying equipment (miniature greasers) fit to oil holes are also available. For order of these parts for lubrication, see Table 1 on Page 2. Table 5 Oil hole specifications Scraper asing nd plate d 1 Rubber Part of nd Seal nd seal ust Protection No end seal is provided for the series. For applications in other than clean environment, cover the whole unit with a protective case, etc. to prevent harmful foreign substances such as dust and particles from entering. We can also attach end seals (supplemental "/US") on both sides of the slide unit. If needed, indicate the supplemental. ven with the use of the end seals to prevent dust from entering, if large amount of contaminants or dust are floating, or if large particles of foreign substances such as chips or sand may adhere to the track rail, it is recoended to attach a protective cover to the linear motion mechanism. asing nd plate andling A strong grip on the circulation pipes of the series slide unit, will distort the circulation path, which may affect the operating performance; handle with care. Mounting surface, reference mounting surface and typical mounting structure When mounting the series, properly align the reference mounting surfaces and of the track rail and the slide unit with the reference mounting surface of the table and the bed and fix them. (See Fig.2) The reference mounting surfaces and and mounting surfaces A and are precisely ground. Machining the mounting surface of the table and bed, such as machine or device, to high accuracy and mounting them properly will ensure stable linear motion with high accuracy. Reference mounting surface of the slide unit is the upper surface when you see the mark on the surface in normal position. The track rail reference mounting surface is identified by locating the mark on the top surface of the track rail. It is the side surface above the mark (in the direction the arrow point). (See Fig.) Shoulder height and corner radius of the reference mounting surface For the opposite corner of the mating reference mounting, it is recoended to have relieved fillet as indicated in Fig.. Recoended value for the shoulder height on the mating side is indicated in Table 6. h Fig. orner of the mating reference mounting Table 6 Shoulder height and corner radius of the reference mounting surface Mounting part of slide unit Mounting part of slide unit Shoulder height h 1 orner radius R 1 (maximum) Mounting part of track rail Shoulder height h 2 orner radius R 2 (maximum) h Mounting part of track rail With end seals supplemental /US d unit: A Fig. 2 Reference mounting surface and typical mounting structure Tightening torque for fixing screw Typical tightening torque for mounting of the series to the steel mating member material is indicated in Table 7. When vibration and shock of the machine or device are large, fluctuating load is large, or moment load is applied, fix it by using the torque 1.2 to 1.5 times larger than the value indicated in the table as necessary. If the mating member material is cast iron or aluminum alloy, reduce the tightening torque depending on the strength characteristics of the mating member material.
