Heavy-Load GEC340XS Radial Plain Bearing with 3° Self-Alignment, 340mm Bore

1. Product OverviewGEC340XS is a large-bore radial spherical plain bearing built for pivot points that carry very heavy radial load at low oscillating speed. Its steel/steel sliding pair with a hard-chrome inner ring sustains high contact pressure, so it is used in rolling mills, mining shovels and big hydraulic cylinders.👉 Get a quote within 24 hours for your project
