Pulleys Bearing NJ222 Cylindrical Roller Bearing for Rowing Machine Parts
Cylindrical roller bearings manufactured in our factory are self-aligning and very strong and durable. They have two rows of rollers that allow the bearing to carry heavy loads.
If you want to know more details, please feel free to contact us.
Therefore, spherical roller bearings can be used in many fields. Such as: machine tools, electrical machinery, railways, automobiles, construction machinery and various professional machinery. We also provide OEM and ODM services.
Integral eccentric bearings, also known as eccentric bearings, are a very useful type of bearing. It mainly includes outer ring, inner ring, rolling element flower basket and rolling element. The overall eccentric bearing has a simple structure and is easy to use. It can realize the eccentric function without an eccentric shaft, which greatly simplifies the eccentric mechanism and saves labor in the machining of the eccentric mechanism. , Time-saving, easy to assemble and reduce the manufacturing cost of the eccentric mechanism.
