Who we are

Bearing supplier China: Made in China, Japan-managed QC

ENRO is a bearing brand for distributors and MRO buyers. The brand sets the specification, the inspection protocol and the packaging, and it answers for every unit that ships under its label. Your inquiry goes straight to the export team, not a call center.

Every ENRO bearing is Made in China, produced at partner factories in China to the ENRO specification. We say so on every page rather than hiding it behind a flag, because the origin is not the point: the checking is. A bearing supplier in China can be anything from a trading desk to a brand with its own protocol; ENRO is the latter, and the model pages show the data you can hold us to.

Japan-managed quality control means the protocol is written to Japanese industrial quality practice and applied at the partner factory: dimensions checked against the model page, then 100% outgoing inspection. Every ENRO bearing — not a sample, every unit — passes outgoing inspection before shipment. Every ENRO bearing carries a verifiable anti-counterfeit label.

ENRO sells on published data: every model page lists boundary dimensions, the versions offered and catalog ratings where confirmed, so you can check the part before ordering. We compete on consistency, not slogans.

Ball bearing supplier: deep groove sizes for motors, hubs and pumps

As a ball bearing supplier ENRO lists 200 single row deep groove ball bearing sizes from 10–160 mm bore, in the 60, 62, 63 and 64 series plus the thin 67, 68, 69 and 160 series. Each size is offered open, with ZZ shields, with 2RS seals or with an NR snap ring groove where the CSV lists it. The sizes most often on a distributor list are the motor and hub sizes: 6201, 6202, 6203, 6204, 6205, 6206, 6207, 6208, 6301, 6302, 6308 for electric motors, and 6201, 6202, 6203 and 6301 for motorcycle hubs. Sizes with 2RS seals are grouped on the sealed bearing page.

Roller bearing supplier: spherical roller sizes for gearboxes, conveyors and screens

As a roller bearing supplier ENRO lists 231 spherical roller bearing sizes from 25–500 mm bore in the 213, 222, 223, 230, 231, 232, 238, 239, 240, 241 and 248 series. Every size comes with a cylindrical bore or a tapered bore (K, or K30 for the 240 and 241 series) and with the W33 lubrication groove. Typical enquiries are 22210, 22216, 22220 and 22312 for gearboxes and conveyor pulleys, and the 231 and 241 series above 150 mm bore for mill and screen positions.

Industrial bearing supplier for distributors and MRO buyers worldwide

ENRO supplies distributors and MRO buyers worldwide: stockists who need one brand, one box and one label across repeat orders, and maintenance buyers who need a part list matched to sizes they can check. Send the list in any format. Each line is matched to an ENRO model by boundary dimensions using the bearing cross reference, the version is confirmed, and the quotation names the model page for every line so that nothing is bought on a description alone. The home page summarises the lines; the table above is the full supplier of bearing sizes by series.

Judging a supplier of bearing sizes you cannot yet hold comes down to what is published and what is checked. Look for boundary dimensions that can be read against ISO 15, catalogue ratings that follow ISO 281 rather than round numbers, a stated clearance group, a marking on the ring that matches the box, and a box that does not change between orders. ENRO publishes the first three on every model page and states the last two on every page of this site. Repeat orders come from the same supplier, bearing by bearing, in the same box; a sample order is the way to confirm that before a container, and the model pages are the way to check each line before the sample ships.

Same base number, same boundary dimensions: the ENRO model is dimensionally interchangeable with the number on your drawing.
Same color, same box, same label: repeat shipments match on the shelf.
Free samples are available. Payment terms are as set out in the sales contract.
