SKF PHF FX10-20X47, 20mm ID, 47 mm OD Keyless Bush, 27.5 mm, 240 Nm

This keyless bush is a locking device designed to secure shafts without traditional keys, providing a Compact method of torque transmission in rotating assemblies. It is intended for use where a reliable interference-free connection between shaft and hub is required, especially in automation and mechanical systems that demand simplified mounting and dismounting.

• High torque capacity delivers 240 Nm of transmitted torque
• Fits 20mm shaft bores for direct shaft clamping
• 47mm outside diameter for compatible hub interfaces
• Short axial length permits Compact assembly integration
• Keyless locking design enables Rapid installation and removal

• Suitable for mounting gears where keyed connections are unsuitable
• Ideal for securing pulleys in automated conveyor drives
• Used for coupling servo motors to driven components
• Can be used for quick-change tooling in production lines

It is engineered to clamp a 20mm bore shaft, providing a direct shrink-fit style connection without keyways.

Its 27.5mm axial extent reduces the required face space, allowing denser component placement on shafts.

The hub or mating bore should accept an external diameter of 47mm to ensure correct seating and load distribution.

Use it where required torque transmission does not exceed 240 Nm to maintain designed clamping performance.
