SIBCO Bearing

The main difference between FC and FCD types of rolling mill bearings lies in their structure and application scenarios.

FC type rolling mill bearing is a separable bearing commonly used for small bearings. Its structure consists of an inner ring and two paired outer components, each of which includes an outer ring with a stop edge, a solid cage, and two rows of rollers. This type of bearing is suitable for high-speed rotating applications, such as the working roll parts of four roll, six roll, and twelve roll cold rolling mills.

FCD type rolling mill bearings are also separable bearings, mainly used for medium and large bearings. Its structure consists of two paired inner rings and two paired outer components, including an outer ring with a blocking edge and a solid cage. FCD type bearings are not only suitable for high-speed rotation, but also can withstand heavy loads at the same time. They are commonly used in profile finishing mills and high-speed wire roughing, intermediate rolling, and pre finishing rolling parts.

Characteristics and applicable scenarios of FCDP type rolling mill bearings

FCDP type rolling mill bearings are mainly used for extra large bearings, which have the maximum radial bearing capacity and low friction coefficient. This type of bearing is suitable for high-speed, heavy-duty, and harsh working environments at the roll diameter of rolling mills. Its structure consists of two inner rings, two outer rings, four rows of rollers and cage components, two flat retaining rings, and one middle retaining ring. FCDP type bearings can provide maximum radial load capacity within a given installation space and have a low coefficient of friction, making them particularly suitable for heavy machinery and equipment.
