Product Introduction
The ZARF1762 L-TV is a premium, high-precision combined axial/radial bearing specifically engineered for the rigorous demands of machine tool engineering. Measuring 17 x 62 x 57 mm, this unit combines a radial needle roller bearing with a double-direction axial cylindrical roller bearing. The "L" designation indicates an extended (stepped) shaft washer, which provides an ideal mating surface for ball screw applications, while the "TV" suffix denotes a high-performance glass-fiber reinforced polyamide cage. Manufactured to stringent precision classes, the ZARF1762 L-TV guarantees maximum rigidity, ultra-precise shaft location, and exceptionally low friction, making it an indispensable component for global manufacturers of CNC machinery and precision linear actuators.
Applications
CNC machine tool precision ball screw supports.
High-speed linear actuators and automation guide systems.
Precision rotary tables and indexing heads.
FAQ
Q: What is the main benefit of the ZARF combined bearing design?
A: It manages both heavy radial forces and bidirectional axial forces within a single, highly compact unit, significantly saving space and simplifying machine design.
Q: Are mounting holes pre-drilled in the outer ring?
A: Yes, ZARF series bearings feature factory-machined mounting holes on the outer ring for direct installation into the adjacent machine structure.
