ZF 441438 - Needle Bearing Ø25×40×14 mm for Marine and Industrial Applications
The ZF 441438 Needle Bearing is a compact, high-load capacity component designed for precision performance in marine and industrial systems. Manufactured from corrosion-resistant steel, it offers smooth rotation, reduced friction, and long service life even in saltwater conditions. Ideal for tight installation spaces, this bearing supports both radial and axial loads, making it a versatile and reliable solution for high-speed, high-stress environments.
Key Features:
- Compact needle roller bearing for confined space applications
- Supports both radial and axial loads up to 12,500 N (dynamic)
- Constructed from high-strength, corrosion-resistant steel
- Designed for high-speed operation—up to 8000 RPM
- Low-friction operation reduces component wear
- Suitable for saltwater and freshwater environments
- Long service life and low maintenance requirements
- Open design allows external lubrication (grease or oil)
