This is because plain cylindrical bearings have more contact surface area than rolling element bearings, so loads are more evenly distributed across the surface. Cylindrical bearing applications may include applications with either radial or axial loads.
Switching from rolling element bearings to GGB cylindrical bearings results in savings from lower parts costs, low-risk assembly and installation, relaxed shaft tolerances and surface finish plus hardness requirements. Cylindrical bearings resist damage from fatigue, shock and edge loads, and they tolerate misalignment better than rolling element bearings. Ultimately, customers will experience savings from lower maintenance costs and extended equipment life.
Cylindrical bearings have straight outside and inside diameters and are flush inside the housing. Due to their simple construction, cylindrical bearings are easy to install with a simple press fitting, reducing potential installation damage. They are slim, which saves space and weight, and cylindrical bearing sizes vary according to their use and client needs.
GGB offers many shapes, sizes and materials of cylindrical bearings, including:
Cylindrical bearings are extremely versatile and may be used for many applications. Common cylindrical bearing uses include:
Additional uses may include offshore FPSO systems, brake mechanisms, alternators and starter motors.
Cylindrical roller bearings are a common bearing type with many advantages and some disadvantages. The following are the main advantages and disadvantages of cylindrical roller bearings:
High Load Capacity: Cylindrical roller bearings are uniquely designed to withstand large radial loads and a certain degree of axial loads, which makes them suitable for applications requiring high load-bearing capabilities, such as heavy machinery and construction equipment.

High Stiffness: Cylindrical roller bearings generally have high stiffness, providing stable axial positioning and precise motion control due to their design. This is useful in applications requiring high accuracy.
Long Life: Cylindrical roller bearings generally have a long life due to their design and durability, which requires less frequent maintenance and replacement.
Suitable for High-temperature Environments: Cylindrical roller bearings can operate in high-temperature environments because they are usually made of high-temperature materials and can withstand high temperatures.
Various Sizes and Types: Cylindrical roller bearings are available in a variety of sizes and types for a variety of different application needs, from small machinery to large engineering equipment.
Friction and Heat: Due to the larger contact area, cylindrical roller bearings may generate more friction and heat at high speeds, which may require additional lubrication and cooling measures.
Axial Space: Cylindrical roller bearings require more space in terms of axial space and therefore may not be suitable in applications with limited space.
Lubrication Requirements: To ensure proper operation, cylindrical roller bearings require proper lubrication. Insufficient or incorrect lubrication can result in bearing damage.
Higher Price: Cylindrical roller bearings are generally more expensive, which may increase equipment manufacturing costs.
