About Wuxi Bokai Light Bearing Co., Ltd - Bearing Supplier in China

Wuxi Bokai Light Bearing Co., Ltd operates from Wuxi in the Jiangsu province of China and currently lists five active bearing products. The company’s catalogue falls under the HS‑2 digit heading 84 for machinery components, with bearings commonly classified under HS code 8482. Its product portfolio includes linear guide bearings, wheel hub bearings, single‑direction bearings, and two variants of angular contact ball bearings. The supplier is listed as an imported tier with a harbor trust rating, indicating that it participates in cross‑border trade through major Chinese ports. Buyers can therefore expect standard export documentation such as commercial invoices, packing lists, and certificate of origin.

The five items in the catalogue are a Line Guide Bearing, a Wheel Hub Bearing, a Single‑Direction Bearing, a Single‑Row Angular Contact Ball Bearing, and a Double‑Row Angular Contact Ball Bearing. These bearings are typically manufactured from alloy steel or stainless steel and are designed for precision motion control and high‑speed applications. Angular contact ball bearings are specified by contact angle and load rating, while line guide bearings are sized by rail width and load capacity. The product names suggest standard bearing series rather than bespoke designs, allowing integration into machinery, automotive, and automation equipment. No additional product variants or custom dimensions are listed in the supplier’s public data.

Product Range and Specialties of Wuxi Bokai Light Bearing Co., Ltd

The catalogue’s five entries cover the main sub‑categories of rolling‑element technology. Line guide bearings provide linear motion support and are commonly supplied in widths from 15 mm to 100 mm with load capacities up to 5 kN. Wheel hub bearings are used in automotive and industrial wheels and are typically rated to ISO 15, 20 or 30 precision classes. Single‑direction bearings allow load transmission in one direction and are often chosen for conveyor or gear applications. Single‑row and double‑row angular contact ball bearings are distinguished by contact angle (usually 15°‑35°) and load‑carrying capability; the double‑row version doubles the dynamic load rating while maintaining similar speed limits. Industry standards such as ISO 281 (bearing life) and ISO 76 (radial load) apply across these types, and buyers normally specify bore size, dynamic load rating (C value) and speed rating (RPM) when ordering.

Trade and Export Information - Wuxi Bokai Light Bearing Co., Ltd

China is the world’s largest exporter of precision bearings, and products classified under HS 8482 are regularly shipped to Europe, North America, and the growing markets of Southeast Asia. Importers typically require compliance with ISO 9001 quality‑management systems and may request CE marking for equipment that incorporates the bearings. Standard packaging includes anti‑corrosion paper‑coated cardboard boxes placed on wooden pallets, with moisture‑barrier liners for high‑humidity routes. Export shipments are commonly arranged on 20‑ft or 40‑ft containers, where a single container can hold several thousand small‑size bearings or dozens of larger units. FOB Shanghai, Ningbo or Shenzhen are the usual incoterms used by Chinese bearing exporters, while buyers often negotiate CIF for European ports to simplify logistics.

Sourcing from Wuxi Bokai Light Bearing Co., Ltd - Buyer Guidance

When sourcing from this supplier, buyers should request a material certificate that confirms the steel grade (e.g., AISI 52100 or AISI 304) and a test report that validates dynamic and static load ratings according to ISO 281. It is prudent to obtain a sample for dimensional inspection and a hardness test (typically 60‑65 HRC for alloy steel bearings) before confirming larger volumes. Verify that the supplier holds an ISO 9001 certificate and ask for any additional certifications required by the target market, such as CE or RoHS declarations. Confirm packaging details, including the number of units per box and pallet configuration, to ensure compatibility with the buyer’s warehousing and handling processes.

What bearing types does the supplier offer?

The catalogue lists five standard bearing types - line guide, wheel hub, single‑direction, single‑row angular contact ball, and double‑row angular contact ball bearings - each classified under HS chapter 84, heading 8482.

Which material standards are typical for these bearings?

Bearings from Chinese manufacturers are usually forged from alloy steel (AISI 52100) or stainless steel (AISI 304/316) and are supplied in accordance with ISO 281 and ISO 76 specifications.

What certifications should a buyer request?

Buyers should ask for an ISO 9001 quality‑management certificate, a material certificate confirming steel grade, and test reports that verify dynamic and static load ratings per ISO 281.

What are common dimensions and load ratings for the angular contact ball bearings listed?

Single‑row angular contact ball bearings are commonly available in bore sizes from 10 mm to 200 mm with dynamic load ratings ranging from 10 kN to 250 kN; double‑row versions typically double the load capacity while maintaining similar bore ranges.

What packaging and shipping methods are used for these bearings?

Bearings are usually packed in anti‑corrosion paper‑coated cardboard boxes, grouped on wooden pallets, and shipped in 20‑ft or 40‑ft containers; FOB Shanghai or Ningbo are the typical incoterms for Chinese bearing exporters.

What is a typical minimum order quantity and lead time?

Standard bearing lines often have a minimum order quantity of 500 pieces per model, with a production lead time of 25‑35 working days after receipt of a confirmed purchase order.

How can a buyer verify the quality before full shipment?

Buyers can request a pre‑shipment sample for dimensional inspection, a third‑party lab test report for hardness and load capacity, and a compliance declaration for any required CE or RoHS standards.
