Overview
A ball plunger locking mechanism holds parts with a spring-loaded ball that snaps into a groove. The POM plastic body presses into a bore, so no separate housing is needed, and the ball releases when the mating part moves. Spring force ranges from 0.54 N to 15 N depending on size, in light load and heavy load types.
Available Sizes and Options
Seven sizes from D1 2 mm to D1 10 mm (body D3 2.5 - 10.6 mm). Light load types start at D1 2; heavy load types are available from D1 4 mm up, with body lengths L1 from 3 mm to 14.5 mm. Custom sizes are quoted from your drawing under our OEM/ODM service.
