Helpful for Model Matching:
| Status / identity | Official archived SU catalogue is marked Discontinued on every page. SU single rod, SUD double rod, SUJ adjustable stroke. Historical-code matching does not confirm present stock or factory production; send original label for availability or replacement review. MU mini-free-mount source is unrelated and excluded. |
| Operation / temperature | Bores 32/40/50/63/80/100; double acting, air filtered 40μm. Working 0.15–1.0MPa; proof 1.5MPa is not working pressure. Standard −20 to +70°C; speed 30–800mm/s. Adjustable air cushioning front/rear; cushion stroke 32/40/50/63=21mm, 80=28mm, 100=29mm. |
| Historical thread / seal / magnet | 32 port 1/8; 40/50=1/4; 63/80=3/8; 100=1/2. Thread blank PT, G: G, T NPT in this older SU ordering source (unlike current SAU/JSI). Seal blank TPU, H Viton, N NBR. Blank without magnet, S with magnet. Feature mentions heat-resistant seal operation at 150°C, but no complete high-temperature working envelope is given: application needs confirmation, never use as standard rating. |
| Discrete standard stroke | Listed 25/50/75/80/100/125/150/160/175/200/250/300/350/400/450/500mm; 40–100 also 600/700/800/900/1000. Max.std columns32=1000; 40/50=1200; 63/80/100=1500; max1800 all. Columns do not authorize arbitrary listed standard strokes. Nonstandard strokes need confirmation. Tolerance 0–250: +1/0; 251–1000: +1.5/0; 1001–1500: +2/0mm. |
| Mount / adjustment | SU blank/LB/FA/FB/CA/CB/TC. SUD/SUJ blank/LB/FA/TC only. SUJ adjustment 10/20/30/40/50/75/100; exact rear envelope and both rods must be checked, adjustment above working stroke retained for human review. TC with TCM1; TCM1 not a complete-cylinder suffix. TC accessory installed on barrel before shipment; position cannot be arbitrarily changed, TC alone cannot mount directly on a standard cylinder barrel. |
| Sensors / accessories | Historical source CS1-B/DS1-B, CS1-F/DS1-F, CS1-U/DS1-U only with magnetic cylinders; exact B code changes by bore. No automatic current EMSG/CMSE retrofit. SU TC bracket codes F-SU32TC...F-SU100TC; TCM1 shown F-SI32TCM1 then F-SC40/50/63/80/100TCM1. Other mounting accessories mostly F-SC; use exact source table, not generic SU prefix. LB/FA allowed all; FB/CA/CB excluded SUD/SUJ. |
| Fit / successor boundary | Profile body without exposed tie rods. Source says shorter than ISO15552 at same bore; no ISO universal interchangeability, clean-room rating or 100% fit guarantee. Shared newer sensor catalogue states SAU substitutes SU with corresponding sensor adjustments; not proof of identical dimensions or electronics. Compare old SU own drawing and current SAU independently. Keep original code and installed envelope, hole pattern, rod thread, and both rod ends. |
| Materials / thrust / RFQ | Source material table includes aluminium barrel/caps/piston, carbon-steel rod 20μm chrome and mixed TPU/NBR seals; no universal custom BOM promise. Magnetic/nonmagnetic dimensions same. Own SU/SUD/SUJ dimension tables and labelled A(SUD)/A(SUJ). Pressure-area thrust table is not side-load/payload rating; commissioning begins with minimum buffer setting. Send model/photo, quantity, destination and required replacement drawings for quotation. |
