Stopplager

Stopplager is a term used in German to describe a type of bearing that allows for linear motion in one direction while preventing it in the other. Essentially, it acts as a one-way lock for linear movement. These bearings are designed with a mechanism that engages when force is applied in the blocking direction, arresting motion. When force is applied in the allowed direction, the mechanism disengages, permitting free movement. This functionality is crucial in various mechanical systems where precise positioning or controlled movement is required.

The design of a stopplager can vary, but commonly involves features like pawls, ratchets, or specialized roller elements that interact with a corresponding track or surface. These components create a unidirectional frictional or positive lock. Applications for stopplager are diverse and can be found in automated machinery, lifting devices, conveyor systems, and adjustable furniture. Their primary purpose is to hold a load in a specific position or to control the direction of movement to prevent unwanted slippage or back-driving. The term itself, "Stopplager," directly translates to "stop bearing," highlighting its core function.
