Import Heavy Duty Supper Lubricating Bearing — Buy in Bulk from Supplier in China

The Heavy Duty Supper Lubricating Bearing supplied by Tangshan Yuanneng Imp. & Exp. Trading Co., Ltd. is a seal‑less sleeve bearing that incorporates blind‑hole oil pits distributed across the internal surface. Unlike conventional oil‑groove bearings, the oil pits provide an oil reserve capacity of three to five times that of normal grooves, extending service intervals. The design eliminates blind zones where lubrication can be insufficient, allowing continuous oil flow with minimal sliding action. These features together preserve the bearing's load‑carrying ability and prolong its operating life.

The bearing is fabricated from standard high‑carbon chromium steel, a material commonly used for heavy‑duty rotary components because of its wear resistance and hardness. Typical industrial bearings of this class are offered in bore diameters from 30 mm to 200 mm and outer diameters up to 250 mm, with C3 clearance and speed ratings up to 3000 rpm. The seal‑less sleeve concept is a recognized advancement that reduces maintenance frequency while maintaining dimensional stability. Such specifications align with the expectations of equipment manufacturers seeking long‑lasting lubrication solutions.

Primary applications include excavators, rotary drilling machines, heavy‑duty loaders and diaphragm‑wall grab equipment, where continuous operation under high loads is essential. Importers targeting these sectors should request sample performance data, confirm the oil‑pit layout and verify that the bearing complies with relevant ISO 281 fatigue life standards. The supplier does not disclose minimum order quantities, packaging details or lead times, so buyers need to obtain those figures directly before finalising a contract.

Tangshan Yuanneng Imp. & Exp. Trading Co., Ltd. is located in Lubei District, Tangshan, Hebei Province, China (postal code 063000). The company is listed with a harbor trust tier, indicating it participates in verified trade networks, although its recorded response rate on the platform is currently 0 % and no average response time is available. The profile does not provide details on years of operation, production capacity or specific certifications, so those aspects should be clarified with the supplier.

The supplier’s catalogue focuses on engineered bearing solutions such as the Heavy Duty Supper Lubricating Bearing, targeting equipment manufacturers that require extended maintenance intervals. No additional information about export experience, quality management systems or third‑party audit results is disclosed, therefore importers are advised to request relevant documentation before placing an order.
