Main Bearing
The Main Bearing offered by Yantai Chunsheng Sliding Bearing Co., Limited is a precision component that supports the crankshaft in internal combustion engines. It is supplied in three material options: Babbitt metal (white metal), copper‑lead alloy and aluminium alloy, as stated in the supplier’s data. These bearings are manufactured to reduce friction and maintain smooth rotation under load.
In the bearing industry, Babbitt and copper‑lead alloys are commonly used for their conformability and embeddability, while aluminium alloys provide lighter weight for high‑speed engines. Typical main bearings of this class have an inner diameter range of 30‑150 mm, outer diameter 60‑300 mm and width 10‑50 mm, with hardness values between 58‑62 HRC. They are usually classified under ISO 15243 for journal bearings and are lubricated with oil or high‑temperature grease. Dimensional tolerances are generally ±0.02 mm for bore and ±0.05 mm for outer dimensions, which ensures interchangeability in engine rebuilds.
The bearings are used by automotive manufacturers, marine engine rebuilders and industrial equipment makers who require reliable OE replacement parts. Importers should confirm the required material grade, packaging size and any specific certification the buyer needs before placing an order. Typical trade terms include FOB Qingdao or C&F Shanghai, with payment by T/T against copy of Bill of Lading, but exact incoterms must be agreed with the supplier. Because the supplier’s response rate is currently recorded as 0 percent, buyers are advised to verify communication channels and lead‑time expectations directly.

Logistics for this product are commonly arranged under FOB Qingdao or C&F Shanghai.
