The INA ZARF50140-L-TV is a high-performance combined needle and thrust roller bearing, specifically engineered for double-direction load handling in heavy-duty industrial scenarios. Meticulously designed to integrate radial and axial load-bearing capabilities, this bearing combines robust structural design with premium materials to guarantee long-term reliability and stable operation in precision-required applications.
Key specifications include a bore diameter of 40mm, outer diameter of 115mm, and width of 115mm. It boasts an impressive dynamic load rating of 128,000N and static load rating of 340,000N, with a maximum grease-lubricated rotational speed of 2,400 rpm. The "L-TV" designation indicates its optimized internal structure for enhanced load distribution and stability, making it suitable for high-load, low-speed operating conditions.
Core features of this bearing include a compact integrated design that eliminates the need for separate radial and thrust bearing assemblies, reducing installation space and assembly complexity. Its precision-ground raceways and high-strength brass cage ensure smooth operation and uniform load transfer, while the pre-lubricated configuration enables immediate use and minimizes maintenance requirements.
Typical applications cover heavy-duty industrial gearboxes, reducers, hydraulic cylinder assemblies, construction machinery lifting mechanisms, precision ball screw drives, and energy mining equipment—where double-direction load requirements, space constraints, and long-term operational stability are crucial considerations.
