About DTMZ Bearing
Specialized mining machinery bearing supplier based in Wafangdian, Dalian — China's largest bearing manufacturing cluster. Spherical roller bearings, crusher bearings, vibrating screen bearings for mining, quarry and heavy equipment applications.
Dtmz Bearing — Your Mining Bearing Partner in China
DTMZ Bearing (DTMZ Bearing) is an independent bearing supplier headquartered in Wafangdian, Dalian, Liaoning Province — China's largest and most established bearing manufacturing cluster. Our location gives us direct access to a network of specialized factories producing spherical roller bearings, cylindrical roller bearings, deep groove ball bearings and tapered roller bearings for mining, construction and heavy equipment applications.
Unlike a single-factory supplier, DTMZ sources from multiple qualified manufacturers in the Wafangdian cluster. This approach allows us to offer a wider range of bearing types and sizes, flexible minimum order quantities, competitive pricing, and the ability to fulfill mixed-model orders that single factories may not accommodate. For mining operators, quarry owners and heavy equipment maintenance teams, this means one reliable contact for multiple bearing requirements.
Our core focus is mining machinery bearings: spherical roller bearings (222CA, 223CA, 230CA, 231CA, 232CA, 241CA series), cylindrical roller bearings for crushers, and deep groove ball bearings for vibrating screens. We also supply bearings for conveyor systems, bucket elevators, ball mills, hammer crushers, jaw crushers, cone crushers and other mineral processing equipment commonly used in coal mining, iron ore, gold mining and quarry operations.
DTMZ Bearing serves mining companies, equipment distributors, MRO procurement teams and bearing importers across India, Vietnam, Indonesia, Brazil, Malaysia, the Middle East and Africa. We support export-oriented service with English-speaking sales, technical documentation, inspection photos and reliable ocean freight coordination.
Factory Network & Warehouse Capabilities
Wafangdian Manufacturing Hub
Located in China’s largest bearing manufacturing cluster in Wafangdian, Dalian, Liaoning Province. DTMZ Bearing leverages a network of qualified factories in the region to source mining machinery bearings, spherical roller bearings, crusher bearings and vibrating screen bearings at competitive prices. This cluster advantage gives overseas buyers access to multiple factory options without being locked into a single manufacturer.
Warehouse & Inventory
Common mining bearing models including 222CA, 223CA, 230CA, 231CA, 232CA, 241CA spherical roller bearings and cylindrical roller bearings are organized for fast inquiry response. Mixed-model orders are supported for distributors, mining maintenance teams and heavy equipment repair markets. We keep reference stock of popular sizes to reduce lead time.
Export Packing
Heavy mining bearings require industrial-grade export packing. DTMZ uses VCI paper (volatile corrosion inhibitor) for rust protection, vacuum-sealed bags for moisture control, reinforced wooden boxes for heavy spherical roller bearings, and pallet packing for bulk orders. Each shipment is packed to withstand long-distance ocean freight to Southeast Asia, South America, Africa and the Middle East.
OEM & Neutral Packing Options
DTMZ Bearing supports flexible packing options for wholesale and OEM orders. Whether you need neutral (blank) packing with no brand markings, your own customer label and logo, or color box packing for retail distribution, we can discuss the packing arrangement based on your order quantity and target market requirements.
Neutral Packing
Plain white or kraft box with no brand markings. Suitable for distributors who apply their own branding locally or sell under their own company name.
Customer Label
Your logo, brand name and part number printed on the box label. Requires label artwork confirmation before production.
Color Box Packing
Custom printed color box with your design for retail and aftermarket display. Higher MOQ applies due to printing plate and box production setup.
Heavy-Duty Export Packing
VCI rust-proof paper, vacuum bag sealing, reinforced wooden box or fumigated pallet for mining bearings over 50 kg. Suitable for ocean freight and long-duration shipping.

Quality Control Process
Before any mining bearing shipment leaves our warehouse, we perform a practical quality control process focused on the parameters that matter most for heavy equipment applications. Our QC scope covers:
- Dimensional checks — bore diameter, outside diameter, width and chamfer dimensions verified against order specifications and standard tolerance tables.
- Rotation inspection — free rotation feel and smoothness check. For spherical roller bearings, we verify that the roller set rotates evenly without sticking or abnormal resistance.
- Noise reference testing — basic noise level check during rotation. While not equivalent to anechoic chamber testing, this practical check helps identify bearings with obvious noise or vibration issues.
- Clearance confirmation — C3, C4 or standard clearance verified per customer requirement and bearing type.
- Packing inspection — VCI paper, vacuum seal, wooden box integrity and pallet strapping checked before container loading. Photos provided for customer confirmation.
