Key features

Line contact structure of rollers provides large contact area, capable of bearing super heavy radial loads with excellent performance under heavy-load conditions.

Moderate friction loss between rollers and raceways plus sufficient heat dissipation space make it suitable for equipment with medium and high-speed continuous operation.

Separable inner and outer rings enable easy installation and disassembly. Rollers allow slight axial sliding to avoid jamming caused by thermal expansion from temperature changes.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company in Changzhou, with a broad product scope covering gearboxes, generators, machinery, mechanical and electrical equipment, hardware, electronic products, cables, and related products. It reports ISO 20000 certification and inventory capability, but no overseas agents, branches, warehouses, or showroom. Customization is available from samples and designs, including full, minor, and flexible customization, and new products were developed in the past year. However, no ODM or popular-brand OEM services are provided, and no SDK is available. After-sales controls are weakly documented: no approved-supplier list, corrective-action procedures, or complaint-handling records were provided. Financial evidence is incomplete because the slices only identify years for financial-related records and do not provide assessable performance figures. No customer cases are stated.

Supplier typeThe supplier is explicitly classified as a trading company, while its stated business scope covers wholesale and sales of industrial, mechanical, electrical, hardware, electronic, agricultural, and transportation-related products. This indicates a broad trading and distribution profile rather than confirmed manufacturing ownership.

CertificationsThe supplier reports certification of its management systems under ISO 20000. The slice confirms a certification, although it does not identify the certificate scope, issuing body, or validity period.

After-Sales capabilityThe supplier has attended the Canton Fair and reports inventory capability, but it has no overseas agents or branches, no overseas warehouse or showroom, and no written corrective-action or customer-complaint procedures or records. These documented gaps indicate limited and insufficiently formalized after-sales support evidence.

R&D capabilityThe supplier reports that it had new products during the past year and offers multiple customization modes, supporting some product-development capability. However, it has no available SDK and does not provide ODM services, so the breadth of its innovation and development platform is limited.

Customization capabilityThe supplier explicitly supports customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of a broad customization offering, although the slices do not specify technical limits, tooling, or delivery performance.

Product Q&A

Q:What kind of loads do cylindrical roller bearings mainly bear?

They mainly bear radial loads and have weak axial load capacity, and can hardly withstand large axial force.

Q:Can the inner and outer rings of cylindrical roller bearings be separated, and what are the benefits?

They are separable, which facilitates separate assembly of inner ring, outer ring and roller assemblies, suitable for transmission shafts and gearboxes requiring split installation.

Q:Are cylindrical roller bearings suitable for high-speed scenarios?

Their limiting speed is lower than deep groove ball bearings. They are more suitable for heavy-load and medium-low speed conditions, not for ultra-high-speed equipment.
