Needle roller bearing
Introduction
Needle Roller Bearings (needle bearing) is a cylindrical roller with roller bearings, relative to its diameter, roller
both thin and long. This is called needle roller. Despite having a smaller cross-section, has a higher load bearing
capacity, equipped with a thin and long needle bearing roller (roller diameter D≤5mm, L / D≥2.5, L is the length
of the roller), so radial structure is compact, its diameter size and load capacity and other types of bearings,
minimum diameter, especially for radial dimensions limited support structure.
Feature:
Needle bearings feature a smaller cross-section, higher load-carrying capacity, greater rigidity, and lower inertia
forces that facilitate size and weight reductions in machinery. They're designed to withstand oscillation, perform
under severe conditions, and interchange with sliding bearings. Diverse types of needle bearings are available in
a wide variety of sizes and tolerances, for a multitude of applications.
Application
Wheel and pin bearing is widly applied in packaging machinery, food machinery,
Printing machinery, woodworking machinery, textile machinery, light machinery, mining
Machinery, engraving machines, automation equipment, CNC equipment, etc
