To securely mount bearings onto machine shafts, choose this lock nut and keyway set from SKF. When used together, the components help to stop bearings from coming loose in the event of heavy machine vibrations. They're designed to accommodate axial loads and have a static load capacity of up to 255kN, so are suitable for use in heavy-duty applications. The lock nut has four equally spaced slots around its circumference to accommodate impact hooks and spanners, making installation simple.

• Light weight of 640g for minimal strain on your equipment
• Metal construction for resistance to corrosion and wear

• Manufacturing industry
• Mechanical workshops
• Robotics and automation

First, coat the sliding surfaces of the shaft with light oil to reduce friction, then slide the adapter sleeve onto the bearing. Next, manually screw the lock nut onto the sleeve's thread and tighten it with a hook spanner to the angle specified in the installation manual. Remove the nut and place the keyway, then replace the lock nut and secure it in place using the keyway's tabs.
