For over 30 years, the Simplicity® self-lubricating bearings from PBC Linear has stood the test of time. Often called the “little red bearing” by loyal customers, they have been a popular replacement for failing ball bearing technology. Where ball bearings can seize and catastrophically fail, Simplicity bearings will out-perform and last years longer. Below are some notable limitations and negative outcomes for ball bearings:
In harsh environments such as carpet tufting, granite cutting, or foundry-work, our Simplicity linear bearings have been proven to withstand extreme temperatures, dirt, submersion, and high vibration without failure. The FrelonGOLD® or FrelonJ® liners succeed by eliminating the need for lubrication and metal to metal contact. Fines will embed in the liners, eliminating shaft damage, while wiping action cleans the shaft. The outstanding performance of Simplicity bearings in harsh environments includes:
The results are a reduction in downtime, cost savings, and increased overall satisfaction of the customer. For clean environments, the Simplicity bearing is a great choice:
Simplicity linear bearings are offered in inch, metric and Japanese metric sizes. We have also added many options over the years, including precision and compensated, open and closed, and self-aligning.
Simplicity self-lubricating linear bearings are designed to provide extended life for your linear motion. Our customers often ask the question, “How long will Simplicity linear bearings last?” In order to answer that common question, we have performed real-world tests right here at our facility. Here is what we have found:
The first step is to determine what wear is acceptable for your application. Then, utilizing the test data on this page, you can estimate the wear expected for your given application.
