Two Row Cylindrical Roller Bearing
Two-row cylindrical roller bearings are designed to provide added strength and capacity to carry radial loads. Two-row products are interchangeable and hold ISO/DIN standards. Their inner rings can be interchanged with those of competitors. Two-row cylindrical roller bearings are available in the same size range as single-row products. Standard cage designs include a drilled pocket finger bronze retainer.
SKF double-row cylindrical roller bearings
Double-row cylindrical roller bearings are available in a variety of designs and sizes. They are capable of accommodating high radial loads and medium to high speeds. They are also available in tapered, sealed, and full complement designs. Among their other features, double-row cylindrical roller bearings can accommodate axial displacement.
These bearings are commonly found in gearboxes and pumps. They have high radial load capacity and excellent running properties. This makes them suitable for many applications, including high-speed machinery. These bearings are also commonly used in mining equipment. They also have a high degree of stiffness, making them a preferred choice for heavy-duty applications.
SKF double-row cylindrical roller bearing series includes the NN3030K/SPW33 and the NNU series. The NN series is a double-row cylindrical roller bearing with a tapered bore. It is especially suitable for heavy-duty radial loads. Its tapered bore helps it accommodate high speeds.
ABMA series cylindrical roller bearings
ABMA series cylindrical roller bearings have a standard and are interchangeable with other brands. The standard specifies boundary dimensions, internal clearances, and snap rings. It also describes acceptable tolerances for various runouts. ABMA bearings are used in electric motors and other general industry applications.
Tolerance classes are important considerations when choosing a bearing. The ABMA standard 20 defines five classes of ball bearings. These classes include instrument series ball bearings (standard 12.1 and 12.2), extra thin section ball bearings (standard 12.2), and thin section ball bearings (standard 12.2). Bearings of these classifications are characterized by tighter tolerances and higher precision. At the time the standards were set, manufacturers only mass-produced ABEC 1 and ABEC 3.
Some manufacturers also produce ABEC 7 and ABEC 9 bearings. The standard uses a standard numbering system for metric bores. Bore sizes 04 and up are denoted by a "taper" in the middle. In addition, you can specify a maximum and minimum diameter for a bearing.
SKF ABMA series cylindrical roller bearings
Cylindrical roller bearings of the SKF ABMA series are available in a variety of sizes and designs, with each bearing exhibiting unique properties. Among these features is the varying contact angles of the bearings. They can be used in both internal and external rotational applications.
Bearing codes are used to identify a bearing, and all manufacturers provide a code key for users to identify their bearing. Each letter and number in a bearing code has a specific meaning, and some manufacturers' bearing numbers do not translate to those of other brands. However, most suppliers will provide information about how to convert between different series and manufacturers.
Cylindrical roller bearings from SKF come in a variety of designs. The differences between them include the number of roller rows, inner/outer ring flanges, cage design, and materials used. In addition to these features, SKF cylindrical roller bearings offer high stiffness and can accommodate heavy radial loads.
