When radial bearings are giving you the slip, use this assembly from SKF to hold them in place. It's a lock nut with a built-in locking device that sits on top of or alongside your bearing to stop it sliding along the shaft as it rotates. Thanks to its cylindrical shape, it's a piece of cake to mount. The nut's insert acts as a pressure plate, letting it clamp onto a shaft using friction. This keeps your components securely positioned. By eliminating the need to machine a keyway onto a shaft, this assembly saves time and effort when you're building gear, pulley and conveyor systems.

• Screw and thread construction means it's reusable
• Static load carrying capacity of 9.8kN to cope with weighty applications
• Compact width of 9mm for fitting on short shafts and in narrow gaps

• Paper mills
• Assembly lines
• Packaging systems
• Construction industry
• Agricultural equipment

You can easily tighten and loosen this bearing assembly nut with a hook spanner (204-4536) and then adjusting the set screw to a torque of 4Nm.
