zwa Four-row cylindrical roller bearing

BORE 90-145mm

Four row cylindrical roller bearing allow the use of a larger diameter roller neck, in the specified space to provide the maximum bearing capacity of the friction coefficient is small, suitable for large radial load. Because it is a separate type, the inner ring and roll neck interference fit, prevent and roll neck sliding. Machining is easy to obtain high precision, suitable for high speed and heavy load rolling.
