SKF Bearing Assembly, Lock Nut and Locking Device, 105mm ID, 140mm OD, 18mm Width - KM 21
Ensure your rotating machinery can hold up under heavy movement with this bearing assembly from SKF. To keep your process rolling along, it firmly fixes your bearing to a machine shaft and prevents it from coming loose. Installing the lock nut and locking device on a shaft is no trouble thanks to its simple slip-and-twist mounting method. Four slots around its edge ensure it's easy to get a handle on when securing it in place with a hook spanner (204-4548). Use the assembly with a compatible washer (209-3902) to ensure a secure hold.
Features & Benefits
• Bears axial static loads up to 290kN for use in heavy-duty applications
• M105 thread size for broad compatibility with standard components
• Washer tabs fold into lock nut spanner slots, making it quick and easy to achieve secure installation
• Light weight of 910g to place minimal strain on your equipment
Applications
• Plastic processing
• Material handling
• Industrial automation
Can I reuse this bearing assembly?
Yes, you can reuse this product with a new washer as long as it's not damaged.
