从China供应商批发进口6203 2rs/Zz/Open Bearing — FOB条款

Ningbo Renhe Machinery Bearing Co., Ltd. offers the 6203 deep groove ball bearing in three closure variants: 2RS double rubber seal, ZZ double metal shield, and open configuration. The standard metric envelope is 17 mm inner diameter, 40 mm outer diameter and 12 mm width, with manufacture from high-carbon chromium steel GCr15, equivalent to Japanese SUJ2 grade. The supplier cites operation up to 15,000 RPM, though this figure should be confirmed against the specific seal or shield type and lubrication condition for each application.

The GCr15/SUJ2 material provides the hardness and wear resistance expected in electric motor quality bearings, with uniform hardness distribution across the raceway and rolling elements as claimed. The ZZ shielded variant permits higher speed operation than 2RS sealed versions because the steel shield does not contact the inner ring, though it offers less protection against fine contaminant ingress. The open variant requires external sealing and periodic relubrication, suiting environments where grease replenishment is practical and maximum heat dissipation is needed.

Application scope spans automotive wheel hubs, appliance motors, pumps, gearboxes, power tools, conveyors and agricultural machinery, reflecting the 6203 series versatility across OEM and aftermarket channels. The supplier markets under the RUWH brand, specialising in motor, agricultural and automotive bearing segments. Lead time is cited as typically 15-30 days for container orders, though this should be validated against current production scheduling and order volume.

Ningbo Renhe Machinery Bearing Co., Ltd. is located at No.218, Weier Road, Andong Town Industrial Zone, Cixi, 315327, Zhejiang Province, China.
