When you look at a Gruvmaster roll grooving machine, the cylindrical part mounted beside the roller assembly is not just a housing — it’s the heart of the machine: the hydraulic cylinder.
Inside this compact, heavy-duty cylinder lies the hydraulic oil that drives the entire grooving process. Unlike many ordinary cylinders on the market that require frequent oil replacement, the Gruvmaster hydraulic system is designed for long service life — the oil can be used for two to three years without replacement, maintaining stable pressure and consistent performance.
What truly sets Gruvmaster apart is our dual-patented hydraulic technology, developed and manufactured in-house.
