New options for hydraulic cylinders

New gland and piston combinations are available for Parker’s MMA range of hydraulic cylinders.

In particular, a new low friction gland with stepped seals has been introduced for applications where low friction and an absence of stick-slip are important. The matching piston employs PTFE seals and wear rings, chosen for their low friction performance and high resistance to wear. This option is suitable for piston speeds up to 1m/s.

Where load holding performance is critical, there is a load holding option optimised to give a combination of wear resistance, seal friction and load holding properties.
