Hydraulic type (ETP bushing)
Our proprietary hydraulic system enables a single-bolt connection. By using friction rather than a keyway to join the shaft and hub,
, thereby eliminating the drawbacks and difficulties associated with keyed connections. The structure is simple, making installation and removal easy, and allowing for precise positioning and alignment.
This significantly reduces the workload from design through assembly, adjustment, and maintenance.
