Mechanically Jointed Rodless Cylinder New Basic Type: ø25, ø32, ø40 RoHS The mounting and performance are the same as before. Weight reduction is achieved through the configuration changes of the head cover and cylinder tubing. 17% Reduced Weight 17% lighter Weight comparison (kg) 9.9 New MY1B Conventional model 13% lighter 3.4 13% lighter 5.8 8.2 6.7 3.9 ø25 ø32 ø40 New Back Compared with L unit at 1000 strokes. New Piping can be connected from 4 directions on the head cover Head cover piping increased from 3 directions to 4 with improved piping flexibility. Increase in piping direction allows piping to meet the on-site installation conditions. Front Piping ports Side New Bottom Back Side Front Bottom With hexagon socket taper plug except port 1. New Easy adjustment of cushion needle Adjustment is easier by changing the cushion needle adjustment from side to top. Hexagon wrench Auto switch can be mounted in any desired position. (D-M9 , D-A9 ) Auto switches can be mounted from the front at any position on the mounting groove. Contributes to reduction in mounting time. New Cushion needle Series MY1B MY1B Existing model Front mounting Insert it at the notch and slide it along the mounting groove. CAT.ES20-210A

Improvement of port variations With addition of the back port, piping can be connected to suit the installation conditions.

Maximum Allowable Moment/Maximum Load Mass The above values are the maximum allowable values for moment and load mass. Refer to each graph regarding the maximum allowable moment and maximum load mass for a particular piston speed. Load mass(kg) 1. We recommend an external shock ab- sorber be installed when the cylinder is combined with another guide (connection with floating bracket, etc.) and the maxi- mum load mass is exceeded. 2. Load factor of 0.5 or less When the load factor is high against the cylinder output, it may adversely affect the cylinder (condensation, etc.) and cause malfunctions....

Maximum Allowable Moment/Maximum Load Mass Select the moment from within the range of operating limits shown in the graphs. Note that the maximum load mass value may sometimes Màximum All0Wabl6 Moment be exceeded even within the operating limits shown In the graphs. Therefore, also check the load mass for the selected conditions. Select the load mass from within the range of limits shown in the graphs. Note that the maximum allowable moment value may sometimes Màximum Load MaSS be exceeded even within the operating limits shown In the graphs. Therefore, also check the allowable moment for the...

Specific Product Precautions Be sure to read the below before handling. Refer to back cover for Safety Instructions. For Actuator and Auto Switch Precautions, refer to "Handling Precautions for SMC Products" (M-E03-3) and Operation Manual. The Operation Manual can be downloaded from the SMC website, http://www.smcworld.com When using a cylinder with long strokes, implement When using a cylinder with long strokes, implement an inter- mediate support to prevent the tube from sagging and being deflected by vibration or an external load. Refer to the "Guide to Side Support Application" on page 12....

However, please be advised that with stroke 49 or less, there are cases where auto switch mounting is not possible and the performance of the air cushion may decline. Also when exceeding a 2000 mm stroke, specify "-XB11" at the end of the part...

Piston Speed (For details, refer to pages 16 and 17.) Stroke Adjustment Unit Specifications Note 1) Be aware that when the stroke adjustment range is increased with the adjustment bolt, the air cushion capacity decreases. Also, when exceeding the air cushion stroke ranges on page 8, the piston speed should be 100 to 200 mm/s. Note 2) The piston speed is 100 to 1000 mm/s for centralized piping. Note 3) Use at a speed within the absorption capacity range. Refer to page 8. Note 4) Due to the construction of this product, it may have more fluctuation in operating speed compared to a rod type air...
