The R series get their name from the fact their tube is roll formed and therefore permanently closed, making them non-repairable.

R series springs are available with 0 12, 0 15, and 0 19 mm tube diameters and with stroke lengths up to

125 mm.

There are 4 colour-coded models, whose forces are preset. An adjustable model (black) is also available, that can be ordered to a specific charge pressure or adjusted by customers with the appropriate charging equipment and training.
