Stanomatic Dual Grease Worker – Brass Cups – 17790-2

The Stanomatic Dual Grease Worker removes the variations that can occur in the hand operation of grease workers, particularly with hard greases. It ensures that consistent working strokes are given to grease samples over an extended period of time.

The grease worker has two grease working assemblies mounted on a cast aluminum base by dowel pins and quick release cams. Each grease working assembly comprises a heavy-duty grease pot with screw lid. A plunger passes through the lid and is attached to a perforated metal worker plate. A large-bore grease-cock allows excess air/grease to escape during assembly and insertion of a thermometer.

Methods: ASTM D217, ASTM D7342, IP 50, BS 2000-50, ISO 2137
