Expanded freedom of design for use as a structure beam 2ecause of the high rigidity of the track rail, the track rail can be used as a structure beam, such as a cantilever or both-end support in the machine and equipment. Therefore, freedom of design is expanded for user. Stainless steel selections superior in corrosion resistance are listed on lineup. For details P.-41 4The main metal components made of corrosion-resistant stainless steel are available for small size of 2 and 30 of track rail width. They are suitable for applications where rust prevention oil is not preferred, such as in a cleanroom environment. 17 1=0.102kgf=0.2248lbs. 18

K.]) is pre-packed. Additionally, series has C-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 and LWU series have grease nipple or oil hole as indicated in Table 11. Supply nozzles fit to each shapes of grease nipple and dedicated supplying equipment (miniature greasers) fit to oil holes are also available. For order of these parts for lubrication, see Table 13 and Table 14.1 on page 23, and Table 1 on page 24.

6 Dust Protection Precaution for Use The slide units of series and LWU series are equiped with end seals and upper seals as standard for dust protection. owever, if large amount of contaminant 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. Mounting surface, reference mounting surface and typical mounting structure When mounting the series and LWU series, properly align the reference mounting surfaces and D of the track rail and slide unit with the reference mounting surface of the table and bed and fix them. (See Fig. 2) The reference mounting surfaces and D and mounting surfaces A and C 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 surfaces of slide unit and track rail of the series and LWU series are the opposite side of the mark. (See Fig. 3) 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. 4. Recoended value for the shoulder height and corner radius on the mating side is indicated in Table 13. Tightening torque for fixing screw Typical tightening torque for mounting of the series and LWU series to the steel mating member material is indicated in Table 12. 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. 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.
