LEFSH40RG is made by SMC and is listed in our Electric Actuators category. KKM Solutions is an independent distributor, not an authorized SMC dealer: we source the exact SMC part number LEFSH40RG, and the quote confirms condition and lead time before you order.

Parts we supply are new and genuine unless the quote expressly states otherwise. Where a part is new-old-stock, from excess inventory, refurbished or open-box, the quote says so before you approve it.

Parts we supply are warranted against manufacturing defects for 1 year from the date of delivery; where the manufacturer's own warranty is longer, the manufacturer's warranty applies. The warranty covers repair, replacement, or credit of the defective part and does not cover normal wear items, misapplication, improper installation, or consequential damages. Contact us within 30 days of delivery before returning anything — all returns need a return authorization from the order desk.

No published lifecycle status is on file for LEFSH40RG. SMC lists whether a catalog number is current, superseded or end-of-life on its own product page, and our order desk confirms the status with the manufacturer at quote time, before you commit. Send the part number through the quote form on this page.

Key specifications include Description: LEFS*G is a high performance version of the standard slider, also equipped with the battery-less encoder onboard the motor. This encoder allows the actuator to be powered down without losing its positional awareness. Further, battery replacement and recycling are eliminated. Load capacities have increased 9-50%. Cycle time is dramatically reduced by a combination of higher maximum speed and acceleration/deceleration. Note that maximum speed gains are primarily in the 50-400mm stroke range, ranging from 5-36; Key Features: Body sizes: 16, 25, 32, 40; Stroke range: 50 to 1200mm in 50mm increments; Maximum work load: 75 kg (horizontal); 25 kg (vertical); Maximum speed: 1500mm's (H lead, size 25); Maximum acceleration: 10,000 mm/s² (horizontal); 5,000 mm/s² (vertical); Positioning repeatability: ±0.02mm (±0.015mm high precision type).
