Roller Bearings are a type of Rolling-Element Bearing that uses cylinders (rollers) to maintain the separation between the moving parts of the bearing (as opposed to using balls as the rolling element). The purpose of a roller bearing is to reduce rotational friction and support radial and axial loads. Compared to Ball Bearings, roller bearings can support heavy radial loads and limited axial loads (parallel to the shaft). They can operate at moderate to high speeds (although maximum speeds are typically below the highest speeds of ball bearings). The lubrication method must carefully considered during the design phase when using roller bearings.

[ China Agricultural Machinery Industry News ] The deep loosening operation of agricultural machinery is a mechanized land preparation technique for inter-row or deep soil cultivation through tractor-drag subsoiler or combined soil preparation machine with deep loose parts. This technology can be used to break the hard plow bottom layer, thicken the loose soil layer and improve the soil tillage structure without soiling and undisturbing the original soil structure, thus enhancing soil water storage and moisture and drought prevention. Capacity can effectively enhance the basic production capacity of food, promote the increase of crops and increase farmers' income.
