SKF Lock Washer Bearing Tab Washer for Use With Lock Nut, 65mm Inside Diameter, 79 x 85 x 12 mm KM 13

SKF KM 13 Lock Washer Bearing Tab Washer is a precision-engineered component designed to secure bearings and other rotating parts on keyed shafts by locking them in place with the matching SKF lock nut KM 13. Featuring a 65mm inside diameter and physical dimensions of 79 x 85 x 12 mm, this lock washer ensures firm retention and preloading of components even during demanding high-speed operations. It has no formal standards or approvals but follows SKF's stringent quality manufacturing.

The lock washer is designed to be used together with a lock nut, specifically the M65x2 threaded SKF KM 13, to maintain component positioning and prevent slippage. Installation is simplified through four evenly spaced tabs that require a 90mm HN 12-13 hook spanner for tightening. This component supports a heavy axial static load of 108 kN and weighs approximately 190 grams, ensuring it handles heavy-duty industrial requirements without adding excessive weight to mechanical systems.

This lock washer is reusable when paired with a new washer, offering a sustainable solution for maintenance and repairs. Typical applications include belt pulleys, hoisting equipment, and industrial gears, where secure and reliable bearing fixation is essential. While the washer itself does not come with built-in locking devices, it is designed for use with SKF's MB 13 locking device to prevent loosening during operation.
