6. FAQ (Focus on Medium & Large B2B Buyers Concerns)

Q: Can your four row tapered roller bearings directly replace TIMKEN / SKF original bearings?

A: Yes. Our four row tapered roller bearings are manufactured strictly according to ISO metric and standard inch dimensions. If model number, dimension and suffix match, they can be directly interchanged without modifying existing shaft or housing. For critical core equipment, we can provide load rating and material test certificates for your engineering verification.

Q: What is your MOQ and can we get volume discount for long-term framework contract?

A: Standard in-stock models support flexible MOQ to meet spare parts stocking demand. For bulk container orders and annual framework cooperation, we offer tiered preferential factory pricing and priority production & shipment schedule. You can send your monthly consumption quantity for formal long-term quotation.

Q: What documents can you provide for import customs and quality audit?

A: We can supply commercial invoice, packing list, bill of lading, material certificate, dimensional inspection report and test certificate as required. All documents comply with mainstream import customs requirements for Latin America, Southeast Asia, Middle East and Africa.

Q: How long is your lead time for in-stock and non-stock custom models?

A: Mainstream common models in our warehouse can be shipped within 3-7 working days. Non-standard custom specifications or special inch bearings normally take 25-45 working days. We will confirm exact lead time clearly in the proforma invoice before order confirmation.

Q: What quality guarantee do you offer for bulk orders?

A: We implement full inspection before shipment. If quality defects caused by our manufacturing occur under proper installation and normal working condition within warranty period, we support free replacement or compensation negotiation for bulk orders. We can also arrange third-party inspection (SGS etc.) before delivery if required.

Q: Can you do OEM marking and neutral packing for our resale business?

A: Yes. We support laser marking of your brand logo or part number on inner/outer rings, neutral export wooden packing without our factory logo, which is suitable for distributors and wholesalers reselling to local end customers.

Q: How to confirm the correct suffix (W33 / C3 / C4 / K) for my working condition?

A: You can share original bearing part number, equipment type, operating temperature, load and lubrication mode. Our engineering team will recommend the most suitable suffix configuration to avoid premature failure and extra maintenance cost for your equipment.

Category Overview

30300 Series	Single Row	Medium-heavy load, high rigidity, wide application	Industrial gearboxes, agricultural machinery, construction equipment
32200 Series	Single Row	Thickened section, enhanced radial load capacity	Truck axles, heavy gearboxes, mining machinery
32300 Series	Single Row	Heavy-duty design, maximum radial/axial load capacity	Large reducers, crushers, construction machinery
31300 Series	Single Row	Large contact angle, high axial load capacity	Pump units, compressors, high-thrust applications
33000/33100/33200 Series	Single Row	Compact structure, automotive-optimized	Passenger car/hub bearings, differential gears
Double Row Tapered Roller Bearings	Double Row	High combined load capacity, self-aligning option	Heavy gearboxes, rolling mills, crane wheels
Four Row Tapered Roller Bearings	Four Row	Ultra-high load capacity, separable design	Cold/hot rolling mills, heavy industrial equipment

Core Advantages

High Combined Load Capacity: Effectively bear heavy radial loads and bidirectional axial loads simultaneously.
Separable Design: Inner and outer rings can be installed separately, simplifying assembly and disassembly.
High Rigidity & Impact Resistance: Suitable for harsh working conditions with shock loads and vibration.
Precise Axial Positioning: Accurately control shaft axial play, ideal for precision transmission systems.
Wide Compatibility: Available in multiple series and sizes, covering automotive, industrial, and heavy machinery applications.

Typical Industrial Applications

Widely used in automotive wheel hubs, gearboxes, reducers, mining equipment, crushers, rolling mills, agricultural machinery, construction machinery, pumps, compressors, and other heavy-duty mechanical transmission systems.
