Frequently Asked Questions

Locknuts secure bearings or sleeves to shafts, ensuring they remain aligned and seated during operation. They also help absorb axial loads and prevent fretting.

We recommend replacing both during bearing changeouts. Reusing can compromise preload and introduce risk, especially on rotating equipment.

Yes. Our metric and inch locknuts are made to industry standard dimensions and are fully compatible with major brands like SKF, NTN, and FAG.
