The N311 ECM/P63 is a single-row cylindrical roller bearing designed for demanding industrial use. It combines a chrome steel (GCr15) ring with an ECM phenolic-resin cage, delivering a P63 precision grade that tolerates high speeds and elevated temperatures. The bearing is supplied by Disen Bearing Co., Ltd. and is packaged in standard industrial boxes for safe transport. Its construction targets applications where tight rotational tolerance is essential.
In the bearing market the N311 size typically carries a 25 mm bore, 47 mm outer diameter and a 12 mm width, dimensions that match the standard series used worldwide. A typical maximum radial load for this size is around 5.7 kN, while the permissible speed can reach up to 30 000 rpm under normal lubrication. The ECM phenolic cage reduces friction compared with steel cages, extending service life in high-temperature environments. These characteristics place the N311 among the widely accepted options for mid-range load capacities.
Typical buyers include OEMs of electric motors, gearboxes, compressors and general-purpose machinery that require reliable bearing performance. The supplier states ISO and SGS certification and offers flexible minimum order quantities, allowing both small-batch and bulk purchases. Shipping can be arranged on FOB or CIF terms, with payment options such as L/C or T/T commonly accepted.

Before placing an order, confirm the bearing’s dimensional series and cage material match your equipment specifications. Request the supplier’s ISO and SGS certificates and ask for a recent test report that includes radial load and speed ratings. Verify the part number N311 ECM/P63 and ensure the packaging description aligns with your handling requirements. Clarifying these points reduces the risk of receiving a non-conforming product.
Discuss the preferred Incoterm with Disen Bearing, typically FOB or CIF, and obtain an estimated lead time based on the quantity you intend to purchase. Because the supplier’s response rate is currently zero, ask for a written production schedule and shipping timeline before confirming the contract. Payment terms such as a letter of credit (L/C) or telegraphic transfer (T/T) should be agreed in advance to protect both parties. Ensure that freight forwarder details are shared early to avoid delays.
Arrange for a third-party inspection at the factory or at the loading port to verify dimensions, runout and surface finish against the P63 tolerance. Request a mill test report (MTR) and a certificate of conformity that lists the material grade GCr15 and the ECM cage composition. Keep records of the inspection results and certification for customs clearance and future quality audits. These steps help maintain consistent performance across multiple shipments.
