Installation Time Comparison: Differences in the Number of Bolts | Friction-Type Fasteners PSL, ETP
2026/05/07
This compares the installation times for the PSL-G (wedge-type) and ETP-E Plus (hydraulic-type) friction fasteners. When
joining a shaft and hub, the wedge-type friction fastener takes
approximately 3 minutes, whereas the hydraulic-type friction fastener enables high-precision joining of the shaft and hub in about 20 seconds.(Concentricity: 0.02 mm)
Furthermore, since anyone can secure the connection with a single bolt, no specialized skills are required. Introducing hydraulic friction
fasteners to areas requiring frequent disassembly can result in significant labor savings.
