Cylindrical Roller Bearings

Cylindrical roller bearings are used in many industrial applications. They are highly versatile and can withstand heavy impacts and radial loads. This makes them ideal for high speeds. However, choosing the right bearing is important. You should also consider the operating conditions and load specifications.

Cylindrical roller bearings come in two types. One is a single-row bearing, while the other is a double-row type. The double-row type is known for its high radial rigidity. These are often used in precision machine tools and power transmission.

Cylindrical roller bearings can be made with cages, which are normally machined brass or pressed steel. However, molded polyamide resin cages are sometimes used in specific applications.

A cylindrical roller bearing can be used for a variety of applications, including power generation, motors, rotary equipment, papermaking, and more. In addition, they are used in construction, mining, and recycling. Some cylindrical roller bearings are also found in briquetting machines and rubber mixing equipment. Other applications include gearboxes and pumps.

Cylindrical roller bearings are designed to reduce friction. Their structure allows for easy mounting. Moreover, they can be machined accurately due to their linear contact with the raceway. Although there are a few different types of cylindrical roller bearings, they all have similar basic components. The inner ring has a loose washer. The outer ring is either crowned or end-relieved to help reduce stress concentrations. An additional feature is the flange on the inner and outer rings.

The radial capacity of a cylindrical roller bearing is much higher than a ball bearing. However, its center speed is difficult to evaluate. It's a good idea to consult a manufacturer for information on friction coefficients. There are also oil jets and circulating systems available to cool heavily loaded bearings. Oil is the preferred lubricant in most cases, but grease is used in less demanding situations. If a bearing is to be used in a high-speed environment, the oil should be VI or EP. Typically, the oil contains R&O inhibitors to protect the bearing from contamination.

The dynamic radial load (or DRL) of a cylindrical roller bearing is measured in a nomogram. The inner ring is designed to handle a certain radial load over a certain number of revolutions. The DN number is then calculated by dividing the diameter of the inner ring by the rotational speed. Using a 0.3 million-DN as a starting point for a reasonable life, you can calculate the life of the bearing.

Timken(r) offers a line of two-row cylindrical bearings that meet ISO standards. These bearings have improved performance and reduced maintenance costs. When combined with their proprietary internal geometry, they minimize drag and minimize heat. Additionally, Timken(r) offers ADAPT, a high-capacity, easy-to-assemble design.

Timken(r) ADAPT combines a spherical and cylindrical roller bearing design. The ADAPT is recommended for use in mixed misalignment and axial displacement conditions. Both the spherical and cylindrical roller designs offer high-capacity, easy-to-assemble, and a high load rating.

Cylindrical roller bearings offer many benefits, including low friction, high resistance to high accelerations, and a broader range of load capacity. Therefore, they are a great fit for the environment.
