Mainland supplies the 6204 deep groove ball bearing for industrial distributors, OEM purchasing teams and equipment manufacturers that require a controlled, repeatable sourcing specification. Its common metric boundary dimensions are 20 mm bore, 47 mm outside diameter and 14 mm width. Buyers can request suitable precision, internal clearance, closure, cage, lubrication, marking and private-label packaging options, subject to engineering review. Typical applications include Electric motors, Pumps and fans, Gearboxes. Every quotation confirms the complete order code, material scope, inspection items, MOQ, production lead time and export packing. Final load ratings, speed limits and operating suitability must be checked against the selected internal design and actual application conditions before purchase.
Use this table for RFQ comparison. The final order code and performance sheet are confirmed for the selected configuration.

The downloadable datasheet identifies boundary dimensions, configuration choices, order examples and every performance field that still requires Mainland engineering release.
Document status: RFQ baseline. Final C, C0, speed, mass, chamfer and clearance values require an approved Mainland drawing or technical sheet.Yes. Marking, packaging artwork, quantity and approval samples are confirmed before production.
Share the fit, speed, temperature and application. We will confirm the suitable suffix and inspection limits in writing.
Sample availability, cost and lead time depend on the final configuration and quantity.
FOB named-port quotations are supported. Other Incoterms are reviewed by destination and order size.
Review designation, configuration and quotation requirements before comparing offers.
