How to Calculate the Load of Your Bearing

One important component to selecting your spherical plain bearing is calculating the right load that is needed for your application. This is important because it ensures that your bearing won't fail and results in less time and money repairing or finding a new bearing.

UNDERSTANDING THE IMPORTANCE OF LOAD

An important component in selecting your spherical plain bearing is knowing the load your bearing is required to handle for your application. Calculating the load before selecting your bearing ensures that you select the correct bearing - avoiding failure issues and resulting in less time and money spent on repairing or replacing your new parts.

DETERMINING YOUR LOAD

To determine your spherical plain bearing load, know that the tangential force (F) at the pulley or sprocket of a belt or chain drive must first be converted to shaft load (Ls), and then to spherical plain bearing load.

The formula below provides useful information for determining tangential force (F) when horsepower is given. The bearing example below uses a Mounted Pillow Block.

RISKS OF SKIPPING LOAD CALCULATIONS

There are several risks associated with purchasing components without all the data first. Many of these risks can become costly in both time and money. Here are a few of the most common risks associated with purchasing an incorrect bearing before knowing the correct load or specs:

• Higher level and more frequent maintenance
• Failure in the field or under load
• Time or money wasted on purchasing the wrong part
