Rodless cylinders are the answer to the long-stroke problem: a piston-rod cylinder needs 2× its stroke length of installation space (housing + extended rod), while a rodless cylinder needs just slightly more than the stroke length itself. Norgren's Lintra®Plus M/146000 family uses a patented sealing-band system to transfer force from the internal piston to an external carriage that runs along the same barrel. Three guiding configurations on the same envelope: M/146000 with internal guide, M/146100 with external adjustable guide, M/146200 with precision roller guide (Ø 25-63 mm only). All in Ø 16-80 mm, double-acting with adjustable cushioning, 1-8 bar operating pressure. ATEX zone 1 & 2 (gas), 21 & 22 (dust) versions available for explosive environments.

Rodless if: stroke > 800 mm, installed length matters (gantry, transfer line, pick-and-place), or the load needs guidance along the cylinder (the Lintra carriage is your work platform). Piston-rod if: stroke < 500 mm, simple linear actuation with no need for an integrated guide, or the rod free-end is the work attachment. Crossover region 500-800 mm depends on layout constraints.
The challenge with any rodless cylinder is sealing the lengthwise slot in the barrel through which force transfers from the internal piston to the external carriage. Lintra uses a continuous flexible PUR sealing band that is pulled aside locally as the piston passes, and re-engages with the slot behind it. The patented part is the band geometry and material — the sealing system delivers long life and low leakage over millions of cycles. For exact sealing force curves and lifetime data, see the M/146000 datasheet (en 1.6.009).
All three use the same Lintra Plus barrel, but ship with different carriage guides: M/146000 with internal guide — baseline, guidance is internal to the carriage; optimised for moderate side loads and lower cost. M/146100 with external adjustable guide — external guide element, higher side-load capability, bearing clearance can be field-adjusted; for medium-to-high load installations. M/146200 with precision roller guide — recirculating roller-bearing guide for highest precision and load capacity; available on Ø 25-63 mm only (not Ø 16, 20, 80 mm).
Yes — two brake configurations are available on Ø 25-63 mm via suffix codes. /L1, /L3 = active brake: applying pressure activates the brake (a friction lining presses against a stainless steel band); releasing pressure releases the brake. /L2, /L4 = passive brake (fail-safe): applying pressure releases the brake; on pressure loss a spring engages the lock — for safety position-holding applications where the carriage must not drift on power loss. The passive brake is the only Lintra solution for full fail-locked position hold.
Yes — the /F1 suffix: integrated linear position sensor, 10-30 V DC supply, 16-bit resolution, ±0.006 % repeat accuracy, 4-20 mA output, short-circuit protection, 0.05 % linearity, IP67 rating. Available on Ø 32-63 mm only, minimum stroke 110 mm. For closed-loop or servo-style applications where an external linear encoder is not ideal.
/P (or /PM with magnetic piston) adds a caged-ball linear motion guide — a high-precision linear bearing system can be ordered with the Lintra Plus when the roller guide (M/146200) is not smooth enough, or when very straight motion is needed over a long stroke. Available on Ø 25-63 mm only. Maximum stroke is reduced due to the precision guide: Ø 25 = 900 mm; Ø 32-40 = 1500 mm; Ø 50-63 = 2600 mm. Typical applications: precision assembly/test tables, optical-bench style fixturing.
