Double rowcylindrical rolling bearing is composed of inner ring, outer ring, cylindrical roller and cage. This type of bearing is used in the front of NC lathe spindle and is the most important precision components of this type of lathe.

This type of bearing has the advantages of high precision, low noise, small vibration; high consistent with the machine tool spindle surface after the installation and use, high accuracy, low temperature rise, small run out of machine tools spindle , stable running, small noise. Our company produces SP and P4 double rowcylindrical rolling bearing wholesale, copper holder.

Cylindrical Roller Bearings are bearing in which cylinders are used as the rolling elements as opposed to balls in ball bearings. As such, the rollers have a greater (linear) contact area with the outer ring and are distribute loads across a broader surface. Subsequently, they have a relatively high radial load capacity and are suitable for high speeds. Double-row cylindrical roller bearings have high radial rigidity and are used primarily for precision machine tools.

Pressed steel (with or without tins or fins) or machined brass cages are generally used, but sometimes molded polyamide cages are also available depending on the application. Cylindrical Roller Bearings are also available without cylindrical rolling bearing manufacture cages with a full complement of rollers. This allows even higher loads but at the expense of speed.
