Product Introduction
NU202EC and NJ202ECP are both cylindrical roller bearings, widely used in various mechanical equipment, especially suitable for high load and high-speed operating environments. Their design features, material selection, and application scenarios are different, but all focus on providing high load-bearing capacity and reliability.
1. NU202EC cylindrical roller bearing
Design Structure: NU202EC adopts an open design, which means there is no inner or outer ring seal, suitable for dust-free or low environmental requirements applications.
Rolling element form: The cylindrical roller design allows the bearing to withstand large radial loads, making it suitable for heavy-duty and high-speed mechanical systems.
Inner and outer ring coordination: The outer ring of NU series bearings is groove free, and the inner ring can expand freely, allowing the bearing to move radially within a certain range, suitable for environments with large temperature fluctuations.
Application areas: Widely used in heavy-duty mechanical equipment such as electric motors, reducers, gearboxes, etc.
Main features:
High load-bearing capacity, suitable for heavy-duty applications.
Can run at higher speeds.
Adapt to temperature changes and have good thermal expansion adaptability.
2. NJ202ECP cylindrical roller bearing
NJ202ECP adopts a design with a retaining ring, which enables it to withstand more axial loads during operation. This structure is suitable for situations where it can withstand bidirectional axial forces.
Rolling element form: cylindrical roller, with excellent radial load capacity.
Inner and outer rings and cage:
NJ202ECP adopts a cage structure to maintain the gap between the rollers and the raceway, thereby reducing friction and improving the stability of the bearing.
Application areas: Suitable for drive shafts, electric motors, transmission devices, metallurgical equipment, and other high load machinery.
Main features:
It has good axial load-bearing capacity and is suitable for working environments that can withstand both radial and axial loads simultaneously.
More suitable for work under high-speed operating conditions.
Designing structures can effectively reduce friction and extend service life.
