echnical Specifications
Model: N 317
Brand: GPZ
Type: Cylindrical Roller Bearing (N‐type)
Inner Diameter (d): 85 mm
Outer Diameter (D): 180 mm
Width (B): 41 mm
Design Notes: Plain outer ring, flanged inner ring → allows axial movement of the shaft relative to housing.
Approximate Load Rating: (From catalogue) static/dynamic around 133000 N (≈133 kN) basic dynamic rating.
⚙️ Key Features
✔ High radial load capacity due to cylindrical roller design.
✔ Permits axial shaft displacement in both directions (floating – good for thermal expansion or shaft misalignment).
✔ Low friction and smooth operation typical of precision roller bearings.
✔ Durable construction by GPZ to endure industrial duty and large load conditions.
✔ Versatile usage in medium to heavy‐duty machinery where shaft is not axially located by this bearing.
Typical Applications
Gearboxes, transmissions & drive systems.
Electric motors & large generators where floating mounting is used.
Machine tools and spindles where radial load dominates and axial displacement allowed.
Pumps, compressors and rotating equipment with large shafts and unstable axial positioning.
Industrial machinery, heavy equipment, drive shafts subject to high radial loading.
