Hydraulic cylinders
hydraulic cylinders are the backbone of any hydraulic system. A well designed and manufactured cylinder can go a very long way in increasing the life of a machine, reducing maintenance downtime and thereby reducing operating costs in the long run.
Vima has designed and manufactured hydraulic cylinders upto 2000 Tons indigenously and such cylinders are working satisfactorily at our clients works for the past 2 decades. The hall-mark of any vima hydraulic cylinders is quality tested material, precision machining and good quality seals as per the requirements of application.
Vima cylinders are available in two types of construction and various mounting requirements.
› Tie-rod type construction (Suitable for pressures upto 200 bar).
› Welded construction (Suitable for pressure upto 350 bar).
Salient Features
Piston rods ground and hard chrome plated.
Induction hardened and hard chrome plated EN9 piston rods available as optional.
Pipes are cold drawn seamless pipes (ST 52) and duly honed internally.
Sealing as per specific applications including chevron sets, polyurethane type ‘U’ seals, Double-acting
seals or bronze filled PTFE seals of high quality.
Special polyester resin + polyester fibre + graphite filler guide rings for pistons which provide high

Vima has been a pioneer in adapting thislatest technique in our
cylinders for the past 8 years.
Fully stress relieved structure for higher capacities.
Special front and cover design to replace rod seal without opening entire cylinder.
