从China供应商批发进口22308 E/C3 — FOB条款

The 22308 E/C3 is a spherical roller bearing with a 40mm bore diameter, featuring an E-design configuration that provides enhanced load-carrying capacity compared to standard designs. This bearing incorporates C3 radial internal clearance, which is specifically selected for high-temperature applications and situations where the inner ring experiences significant thermal expansion during operation. The E-design indicates optimized internal geometry with larger rollers and increased contact angles, resulting in improved radial load capacity and extended service life in demanding industrial environments.

Manufactured from chrome steel (GCr15), this bearing utilizes the industry-standard bearing steel grade that provides excellent wear resistance, high surface hardness (typically HRC 60-65 after heat treatment), and superior fatigue life characteristics. The C3 clearance class represents approximately 0.025mm to 0.040mm of additional radial clearance beyond the standard CN class, which is critical for maintaining proper operating clearance in applications involving temperatures exceeding 100 degrees Celsius or where heavy interference fits are required on the shaft.

This bearing is widely applied in electric motors, pumps, conveyor systems, and heavy industrial machinery where reliable performance under radial loading and moderate misalignment is essential. The HS code 8482.20 classifies this product for international trade purposes, facilitating customs clearance and import documentation. Typical buyers include OEM equipment manufacturers, industrial maintenance operations, and bearing distributors supplying the replacement market. Trade terms commonly involve FOB or CIF shipping from Chinese ports with payment via T/T or L/C arrangements.
