- Page 5 Specific Product Precautions Caution on Design Operating Environment Warning Warning 1. Note the weight of the stainless steel products. 1.Fully consider the compatibility of stainless steel. Since the weight of stainless steel cylinders is approximately 1.5 The corrosion resistance of stainless steel is not effective against to 3 times heavier than the standard products (with aluminum all media and corrosive environments.
- Page 6 Specific Product Precautions Maintenance Warning 1.If this cylinder is lubricated, it may cause malfunctions. If grease other than designated is used, it may also cause malfunctions. • Order with the following part number when only the grease for maintenance is needed. Grease pack part number for stainless steel cylinders Grease for food processing machines: GR-R-010 (10 g) 2.

3. Maintenance 3-1. Checks The following checks are required for proper cylinder operation. 1. Smooth operation 2. Changes in piston speed and cycle time 3. Abnormal stroke 4. Looseness of mounting bolt and rod end nuts 5. Looseness of mounting frame and excessive deflection 6. -
Page 18: Replacement Of Seals
3-2. Replacement of seals It is possible to replace the rod seal and piston seal for ø20 to ø40. Replacement of the rod seal may be difficult when the scraper remains attached since it has to be removed and inserted through the inside diameter area of the scraper. ！... - Page 19 3-2-2. Removal of seals 1. Rod seal Insert a precision screwdriver from the front of the rod cover to pull out the seal as shown in Fig. 4. ！ Caution 1)Take care not to damage the seal groove of the cover at this time. 2) When the water-resistant scraper is worn out, replace the entire rod cover assembly.
- Page 20 3-2-3. Grease ！ Caution ・Use SMC’s recommended grease. Grease pack part number: GR-R-010 ( 10g ) 1. Rod seal Apply a thin layer of grease to all surfaces of the new seal to make it easy to mount the rod seal and improve sealing. Fill the groove of the seal with grease, which is necessary for operation.
- Page 21 3-2-4. Mounting of seals 1. Rod seal ( Fig.8 ) Pay attention to the mounting direction of the seal. Apply grease to the scraper and the inner circumference of the rod seal as shown in Fig. 2. Piston seal ( Fig. 9 ) Mount with care not to twist the piston seal.
