What are the main applications for these bearings?

They are widely used in papermaking machinery, speed reducers, railway vehicle axles, rolling mills, crushers, vibrating screens, and woodworking machinery.

What precision ratings are available?

The available precision ratings are P0, P6, P5, P4, and P2, allowing selection based on specific operational requirements.

What is the typical working speed for spherical roller bearings?

Generally, spherical roller bearings allow for low working speeds due to their design, though symmetrical designs can adapt to higher speed requirements.

AI-Powered supplier vetting

SummaryZaozhuang Yiding Bearing Co., Ltd. is a China-based trading company established in 2014, specializing in bearing export, sales, production coordination, and after-sales service. It offers multiple bearing categories and reports broad export coverage, with peak- and off-peak fulfillment stated as within 15 working days. The supplier describes quality-assurance and management systems, but supplier-management certification is recorded as NIL. Its stated workforce is seven employees, including 6–10 quality-control staff in another record, creating an internal inconsistency. R&D experience is limited to one year, and no direct customization capability or named customer portfolio is provided. A single trade transaction is recorded, which is insufficient to establish broad customer-case experience. Financial credibility cannot be assessed because the available financial-related information is incomplete and monetary data is excluded.

Supplier typeThe supplier is explicitly identified as a trading company and limited company headquartered in Zaozhuang, Shandong, China. Its stated operations include bearing export, selling, production, and after-sales service, but the available classification identifies it primarily as a trading company.

CertificationsSupplier-management-system certification is explicitly recorded as NIL. Although the supplier claims to have established a strict quality-assurance system, no formal certification is evidenced in the provided information.

After-Sales capabilityThe supplier explicitly states that it provides after-sales service and describes a professional management system covering pre- and post-sales activities. Its company background also lists after-service as part of its operations, providing positive but self-reported evidence of capability.

Production capacityThe supplier reports two production lines, stated product output for ball screws, roller bearings, and ball bearings, and fulfillment within 15 working days in both peak and off-peak periods. However, the company is classified as a trading company and the production information is not independently supported, so capability is evidenced but not fully verifiable.

Product Q&A

Q:What types of loads can spherical roller bearings withstand?

They mainly bear radial loads but can also withstand axial loads in either direction. They are not suitable for pure axial loads.

Q:What is the self-aligning capability of these bearings?

Due to the spherical outer race, they have good aligning performance and can compensate for coaxial errors. The allowed aligning angle is generally 1-2.5 degrees.

Q:What are the available bore types for installation?

They are divided into cylindrical bore and tapered bore. Tapered bores have tapers of 1:12 (code K) or 1:30 (code K30) for mounting on conical shafts.

Q:How can I identify bearings with improved lubrication?

Bearings with an outer ring oil groove and three oil holes are marked with the post code /W33 to indicate improved lubrication performance.

Q:What materials are used for the bearing cages?

Cages are made of steel, brass, or nylon. Specific suffixes include CC (stamping steel), TVPB (glass fiber reinforced polyamide), and CA (machined brass).
