Understanding the Importance of Bearing Clearance

If you are experiencing premature bearing failures, you not only should look at your lubrication practices but also your installation practices. When using an induction heater, it is important to make sure that the heating is steady and even; fast is not always good, especially if you do not know what is happening with the temperature of the outside diameter (OD) of your bearing. Remember that the inner race heats faster than the outer race. Precision bearings are prime candidates. In the picture above, on the left you see a single temperature probe placed on the inside diameter (ID) of the bearing. By the time the temperature of the ID reaches 110 degrees C, the temperature of the OD is only 60 degrees C. This could be a huge problem if the clearance between the ball or roller bearings and the raceways of the ID and OD is not enough to handle the temperature difference. In these cases, the bearing balls or rollers get squeezed between the OD and ID, damaging the bearing before

Determining the Appropriate Lubrication Quantity for Bearings

### Determining the Appropriate Lubrication Quantity for Bearings #### Introduction Proper lubrication is essential for the optimal performance and longevity of bearings. Without the correct amount of lubrication, bearings can suffer from increased friction, wear, and premature failure. This blog provides a comprehensive guide to determining the appropriate lubrication quantity for bearings, covering key considerations, the selection of grease, major manufacturers, and the equipment used for greasing. We will explore the importance of manufacturer recommendations, the impact of bearing type and size, operating conditions, environmental factors, the selection of grease, major grease manufacturers, and the tools needed for effective lubrication. #### Key Considerations **Manufacturer Recommendations**: - **Importance of Following Manufacturer Guidelines**: The manufacturer's recommendations are the primary source of information for determining the appropriate lubrication quantity.

Ways to Extend Bearing Service Life for High Speed Applications

Wear and tear naturally occur overtime for any bearing. For parts used in high-speed applications, the negative effects of wear and tear can become a major issue much sooner. High-speed applications create a pair of problems for your bearing’s wellbeing: more heat and friction. Without proper planning and precautions, the added heat and friction caused by high-speed use can cause churning, slippage, and early breakage. Not only will this lead you to quickly ramp up your part replacement budget, it can also lead to lost potential revenue from unplanned downtime and a need to allocate valuable resources to avoidable issues. Fortunately, a mix of proper bearing selection and preventative measures can help you make sure your bearings are built to handle high speeds. Here’s what you can do to help extend the lifespan of bearings used in high-speed applications. Use proper lubrication One of the best ways to limit the impacts of friction is through proper lubrication. A well-lubricated bea
