Unique design, essential in diverse industries. Withstands high loads in tight spaces, crucial in automotive, machinery, and heavy equipment. Vital in challenging processes like metalworking and metallurgy.
Needle roller bearings use needle rollers as rolling elements, enabling them to handle higher loads, especially in confined radial spaces. Here are some key specifications:
ID (Inner Diameter): The internal hole diameter of the bearing, usually in millimeters (mm).
OD (Outer Diameter): The outer ring diameter of the bearing, also in millimeters (mm).
Height (C): The vertical dimension of the needle roller bearing, also in millimeters (mm).
Needle Diameter: The diameter of the needle rollers, also in millimeters (mm).
Arrangement: Needle roller bearings come in single-row, double-row, or multi-row configurations, based on the mechanical equipment's load and space needs.
