There are oil holes drilled on the inner surface of the shaft sleeve, and some also open oil grooves to allow the lubricating oil to enter the lubrication. In order to prevent dry friction during the start of a diesel engine, an oil storage tank is also formed on the inner surface of some bearings. A small number of small high-speed diesel connecting rod small-end bearings use needle bearings. On the cross-head connecting rod, the small-end bearing is a split sliding bearing, which is often manufactured separately from the shaft. The wear-resistant alloy is directly cast on the inner surface of the bearing. For lubrication. Because small-end bearings work under high pressure and sway conditions, their lubrication is difficult. In order to improve the reliability of lubrication, some models use a dedicated oil pump for each cylinder to enhance lubrication. In order to improve working reliability, self-adjusting or platform connecting rod small-end bearings are often used.
