Coupling Expansion Bushing Z12A Sleeve Shaft Locking Device Assembly Inner Hole Diameter 25-600mm KTR400 STK450 Fastening CNC Tool(Z12A 55x85)

CouplingsZ12A Expansion Sleeve Shaft Locking Device Assembly Inner Hole Diameter 25-600mm KTR400 STK450 Fastening Sleeve CNC ToolZ12A expansion sleeve is a transmission part product with keyless connection structure. Under the action of axial force the inner and outer sleeves of the expansion sleeve shrink and expand to make the shaft and hub closely fit and generate enough friction to transmit torque so as to achieve the purpose of mechanism operation.Origin : ChinaModel Number : Z12A

• Couplings
• 【Product Function】: The main function is to tighten the high-strength bolts to produce a huge clamping force between the shaft and the hub so as to realize the transmission of loads.
• 【Product Features】: Expansion sleeve coupling can transmit large torque through the cooperation of expansion sleeve and shaft which is suitable for heavy load or medium and low speed transmission system.
• 【Application scope】: Expansion sleeve is widely used in various mechanical equipment especially in the need for high load transfer occasions.
• 【Material】: Made of high quality materials to ensure resistance to abrasion and tearing as well as ensuring excellent durability and strength long-lasting.
• 【Easy to install】: Expansion couplings are designed to be user-friendly and can be installed adjusted and disassembled directly.
