Double row, four row tapered roller bearings
Double row and four row tapered roller bearings from Changzhou Din Bearing Co., Ltd are precision-engineered for heavy-duty industrial machinery requiring combined radial and axial load handling. These bearings use chrome steel GCr15 conforming to SAE 52100 standards, with internal geometry optimized for high contact angles to distribute load efficiently across multiple roller rows. The design supports sustained operation under shock loads and misalignment common in gearboxes, steel mill rolls, and construction equipment.
The material grade GCr15 provides high hardness and wear resistance, typical for industrial bearings operating above 150°C. Internal clearances follow ISO 5753-1 tolerances, and cage designs are typically stamped steel or machined brass, depending on speed and temperature requirements. These bearings are not sealed or shielded by default, allowing for custom lubrication in high-dust or high-temperature environments. Surface finish and raceway geometry are ground to achieve micro-roughness values under 0.1 micrometers, aligning with ABMA standard 19.1 for Class 0 and Class 6 precision.
End users include manufacturers of mining conveyors, wind turbine gearboxes, and heavy truck axles who require extended service life under continuous load. Buyers typically order in batches of 50 to 500 units, with packaging in anti-rust paper and corrugated cartons. Trade terms are usually FOB Shanghai or CIF destination port, with lead times of 20 to 30 days after deposit. Certifications are not listed; buyers should request test reports for hardness, dimensional accuracy, and dynamic load ratings before finalizing orders.

Sourcing Double row, four row tapered roller bearings from Changzhou Din Bearing Co., Ltd - China Import Guide
Before placing an order, verify the exact bearing dimensions, including bore diameter, outer diameter, and width, against your machinery’s mounting specifications. Confirm the tolerance class, internal clearance, and cage material, as these are not specified in the listing. Request material test reports for GCr15 hardness and chemical composition. Do not assume compliance with ISO or ABMA standards unless documented. Without this, the bearing may not fit or perform as expected.
Lead time is typically 20 to 30 days, but this is unconfirmed. Confirm Incoterms - FOB Shanghai is common, but CIF may be available. Payment terms are not stated; standard practice is 30% deposit with balance against copy of bill of lading. Ensure packaging includes anti-rust protection and is palletized for container shipment. Clarify whether the supplier provides export documentation, including commercial invoice, packing list, and certificate of origin.
Perform incoming inspection for dimensional accuracy using micrometers and dial indicators. Check for smooth rotation, absence of noise, and consistent torque. Verify the presence of lubricant and absence of debris. Request a dynamic load test report if the application is critical. Retain samples for third-party testing if volume is large. Documentation such as material certificates and dimensional inspection reports must be provided before final payment.
