【Product Series Overview Sample】Friction-Type Fasteners (ETP & Posilock)

The connection between shafts and hubs has traditionally been achieved using keys and keyways. However, this method presents numerous challenges, including the need for high-quality materials, high machining precision, and precise alignment during assembly. The ETP bushing provides a solution to these problems by offering a friction-based connection. The ETP bushing is a product that connects using friction without keys, effectively resolving the drawbacks and difficulties associated with keyed connections.Mechanisms are broadly categorized into two types: hydraulic (oil pressure) and mechanical (wedge). They offer advantages such as simplicity, compact size and light weight, easy attachment and removal, straightforward precise positioning and indexing, and significant reduction in work from design through assembly, adjustment, and maintenance.
