Key features

Adopting line contact between tapered rollers and raceways with large contact area, it can bear radial and axial loads simultaneously, featuring excellent resistance to heavy loads and impacts.

Separable inner and outer rings allow precise adjustment of preload clearance during installation, bringing higher operating rigidity, smoother rotation and better positioning accuracy.

Complete standardized specifications; paired installation supports bidirectional axial force, widely used in axles, reducers, mining machinery, etc. Separable design simplifies parts replacement and r

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 types of loads can tapered roller bearings bear?

This bearing can bear radial loads and unidirectional axial loads at the same time. When installed in pairs back-to-back, it can withstand bidirectional axial loads, and performs well under heavy-load and impact working conditions.

Q:Are the inner and outer rings of tapered roller bearings separable? What are the benefits?

The inner ring, outer ring and roller assembly can be completely separated. The advantages lie in precise preload clearance adjustment during installation, easier assembly and overhaul. Worn parts can be replaced separately later to cut maintenance costs.

Q:What equipment are tapered roller bearings mainly applied to?

They are widely used in heavy-duty equipment requiring combined radial and axial loads, such as vehicle axles, gearboxes, construction machinery wheel hubs, reducers, mining machinery and metallurgical equipment.
