W-000 / WT Series Bearing Lockwashers – Small Profile
Small-profile tongued lockwashers in two matched families: W-000 washers pair with the large-bore N-000 locknuts, and WT washers pair with the compact NT locknuts. Both are reduced in outside diameter and section so the locking assembly clears housings, seals and shoulders that a standard W washer would foul.
