Sealed Four Point Contact Thin Bearing
The Sealed Four Point Contact Thin Bearing, model NJB055XP0, is a compact ball bearing designed for high‑speed servo and aerospace applications where radial space is severely limited. It incorporates high‑carbon chromium steel (AISI 52100 / SUJ2) balls and a rubber seal, with a brass cage to retain the rolling elements. The bearing measures 139.7 mm inner diameter, 155.575 mm outer diameter and a 7.938 mm cross‑section, forming a thin‑ring profile. Its dynamic load rating is 1.040 N and static load rating 3 730 N, as specified by the supplier.
The thin‑section design is typical for precision rotary tables and medical scanners, where axial and radial loads must be accommodated in a limited envelope. The rubber seal provides double‑sealed protection against contaminants, a standard feature for bearings used in aerospace environments. Self‑lubricated grease treatment is common for this bearing class, reducing maintenance intervals. Typical operating speed can reach up to 30 000 rpm, but buyers should confirm the exact speed limit for their application.
The bearing is suited for robotics, medical imaging equipment and precision machining centres that require high speed and low friction. Luoyang Bobi Precision Bearing Co., Ltd. does not list a minimum order quantity, so importers should verify batch sizes directly. Shipping is usually arranged under FOB Luoyang Port, with Incoterms and payment terms negotiable per contract. Prospective buyers are advised to request material test reports and certification of dimensional conformity before finalising the purchase.

Sourcing Sealed Four Point Contact Thin Bearing from Luoyang Bobi Precision Bearing Co., Ltd. - China Import Guide
Importers should first confirm the exact model number, material grade and seal design with Luoyang Bobi Precision Bearing Co., Ltd. Verify that the bearing complies with any applicable aerospace or medical device standards required in the destination market, and request a material test report for the AISI 52100 steel.
Logistics are generally coordinated under FOB Luoyang Port; buyers need to agree on Incoterms such as CIF or DDP based on risk allocation. Payment terms are negotiable and may include a letter of credit or advance payment. Since lead‑time is not disclosed, request a production schedule and estimated shipment date before placing the order.
Quality assurance should involve dimensional inspection of inner and outer diameters, verification of the double‑seal integrity and a check of the bearing’s load ratings. Request ISO 9001 certification or a specific quality management system audit report to ensure manufacturing consistency. Engaging a third‑party inspection agency at the point of loading can further guarantee that the bearings meet the specified technical criteria before dispatch.
