Mechanical Grease Workers
Professional grease working equipment designed for worked penetration and prolonged worked penetration tests to determine the consistency of lubricating greases. Available in mechanical single-unit, mechanical double-unit, and manually operated configurations to suit different testing requirements and laboratory workflows.
Mechanical Models
Mechanical grease workers feature single or dual steel ASTM grease workers mounted on a sturdy base and driven by a powerful gear reduction motor. The equipment meets ASTM specifications for stroke length and rate. A presetting electronic counter automatically shuts off the drive motor after any desired number of strokes up to 99,999. Steel grease workers include threaded cup and cover, and steel plunger plate with shaft and handle that connects to eccentric cam on drive unit. Spring loaded tightening clamps hold grease workers securely on base, and steel pins in base facilitate disassembly of grease workers after testing.
Manually Operated Model
The hand lever operated grease working machine is designed for short duration worked penetration tests on lubricating greases. This model consists of one steel ASTM grease worker with hand lever mechanism mounted on a sturdy steel base. Spring loaded tightening clamps hold grease worker securely on base, and steel pins in hand lever upright support facilitate disassembly of grease worker. Base plate is drilled at corners to allow for bolting to table top.
