Heavy Duty Cylindrical Roller Bearings - Choosing the Right Solution

Whether you need to replace your current bearings or install a new one, choosing the right solution is a crucial step. Whether you need a heavy duty cilindrical roller bearing or a full complement bearing, there are a number of factors to consider before you make a decision.

Spherical roller bearings

Compared to ball bearings, the cylindrical roller bearings are designed to handle heavy radial load and high operating speeds. They are widely used in rotary applications, as they are highly reliable. They are available in a variety of designs and series. They are also suitable for a wide range of applications, including industrial equipment, automotive applications, and railway applications.

The cylindrical roller bearings are typically lubricated with oil. This is to prevent friction and to reduce heat generated during high speed operation. The type of oil used will depend on the operating speed and the load.

These bearings are designed to support radial load, which is parallel to the axis of rotation. This load is typically supported by the inner race of the bearing, which supports a stationary support.

Full complement bearings

MBY(r) cylindrical roller bearings are used in a variety of applications. They offer high reliability and operational durability. They are available in a wide range of dimensions and designs. They are also known for their low noise levels. Some are designed for high radial loads while others are more suitable for axial loads.

MBY(r) cylindrical roller bearings have a logarithmic profile that maximizes the formation of a lubricant film for optimum rolling motion. They also have a high load capacity and are suitable for heavy radial loads. They are used in power transmission, steel mills, mining, and cement processing. They are also used in petroleum production. They also contribute to the quieter running of automobile engines.

There are two different types of full complement cylindrical roller bearings: those that do not have a cage and those that do. They differ in the number of ribs in the inner ring.

Caged design

Designed to withstand significant radial and axial loads, heavy duty caged cylindrical roller bearings are suitable for high speed applications. These are commonly used in gearboxes, electric motors, and other heavy duty machinery.

Bearings come in a wide variety of configurations and sizes to meet diverse applications. The most common types include N, NF, and NJ. These bearings are available in caged or cageless versions. These can be used to support radial loads, moment loads, and combined radial and axial loads. The size and number of rollers vary according to the design.

Bearings are rated based on the number of revolutions a group of rollers completes before the first 10% of the rollers show signs of failure. A bearing's life depends on the type of bearing, the application, the clearances, and the air flow across the bearing.

Misalignment permitted

Depending on the load and the size of the bearing, misalignment of the shaft can occur. This can cause increased operating temperature and running noise. In these cases, self-aligning ball bearings or spherical roller bearings can be used to compensate. These bearings are fitted with a common sphered raceway in the outer ring and are suitable for heavy radial loads.

Roller bearings are also susceptible to misalignment. The inner ring raceway is inclined at an angle to the bearing axis. This provides little contact between the ball and the groove. The outer ring has a large radius to compensate for this lack of ball to groove contact. This type of bearing is usually fitted in rigid housings.

In a self-aligning ball bearing, the balls in the outer ring raceway rotate independently from the needle rollers. This design allows for minor shaft displacements. However, this design is not suitable for compensation of angular misalignments.

Choosing the right solution

Choosing the right solution for heavy duty cylindrical roller bearings requires a little bit of research, as well as some insight into how you will use them. There are several advantages to using roller bearings instead of conventional ball bearings, but you need to choose the right solution for your application.

The simplest way to choose the right solution is to look at your application and the conditions you need to operate in. You should consider load, rotational speed, noise, vibration and other factors that might affect the reliability of your equipment.

You should also consider the type of lubricant you will use. There are several types of lubricants to choose from, including grease, oil and EP oil. You should use oil for heavy loads and high operating temperatures.
