6321 is made by FAG and is listed in our Ball Bearings category. KKM Solutions is an independent distributor, not an authorized FAG dealer: we source the exact FAG part number 6321, and the quote confirms condition and lead time before you order.

Parts we supply are new and genuine unless the quote expressly states otherwise. Where a part is new-old-stock, from excess inventory, refurbished or open-box, the quote says so before you approve it.

Parts we supply are warranted against manufacturing defects for 1 year from the date of delivery; where the manufacturer's own warranty is longer, the manufacturer's warranty applies. The warranty covers repair, replacement, or credit of the defective part and does not cover normal wear items, misapplication, improper installation, or consequential damages. Contact us within 30 days of delivery before returning anything — all returns need a return authorization from the order desk.

No published lifecycle status is on file for 6321. FAG lists whether a catalog number is current, superseded or end-of-life on its own product page, and our order desk confirms the status with the manufacturer at quote time, before you commit. Send the part number through the quote form on this page.

Key specifications include Bore Size: 105mm; Feature: Normal Internal Clearance. The full specification table on this page lists every published attribute for this part.

6321 follows the ISO 15 bore-code convention for metric rolling bearings: the bore code "21" in the designation denotes a 105 mm bore. Outside diameter and width depend on the series; confirm them against the manufacturer data sheet, or ask our order desk at quote time.

Lead time for 6321 is quoted per order and confirmed on your quote, which our order desk sends within 1 business day. For a line-down emergency, call the 24/7 order desk at (825) 454-5367.
