Steel Model Cylinders (S series)

Jastram S Model Actuators are specifically certified for use in commercial marine hydraulic steering systems. Their rugged steel construction includes many standard features resulting from our long experience in the manufacture, operation and service of steering systems.

• Micro-honed heavy wall cylinder barrel
• Precision ground, chrome-plated piston rod
• Tie-Rod construction using re-usable steel tie-rods
• Self-aligning spherical bearings
• Designed with higher pressure rating (2400 psi vs 2000 psi) than those of competitor, facilitating more compact systems than those of our competitor
• JEL using cast steel for Rod End, Tail and Head – cylinders are more compact.
• JEL cylinders designed with extended neck for the rod end – thread connection to the rod end is more strong.
• JEL cylinders provided with adjustable seals on Head – easy to fix problem with leakage at the seal.
• JEL uses steel tie rods – better elongation, better serviceable and can be used after cylinder refit.
• JEL cylinders required less space for the same stroke as competitors.
