Why Choose Eccentric Locking Insert Bearings?
A customer came to us at MDS of Michigan after dealing with a recurring issue on a conveyor line. Bearings kept loosening on the shaft, causing vibration, premature wear, and unexpected downtime. They had tried multiple replacements, but nothing seemed to hold consistently. After a quick review of the application, we recommended switching to NA insert bearings with an eccentric locking collar, and the problem stopped almost immediately.

What Makes Eccentric Locking Different?
NA insert bearings are designed with an eccentric locking collar that tightens in the direction of shaft rotation. Instead of fighting against movement, it works with it. As the shaft turns, the collar naturally locks more securely into place.
That simple design change makes a big difference:
- Locks tighter as the shaft rotates
- Holds strong under vibration and normal operating conditions
- Installs quickly with basic tools
- Requires minimal maintenance once set

For applications that run in a consistent direction, this creates a reliable, long-term hold without constant adjustment.
Where They Work Best
Eccentric locking NA insert bearings are a great fit for:
- Conveyor systems
- Fans and blowers
- Agricultural equipment
- General industrial machinery
If your equipment runs in one direction and you are tired of bearings slipping or loosening, this style is often the fix.
Why It Matters
In many cases, downtime is not caused by the bearing itself, but by how it is locked to the shaft. Choosing an eccentric locking design eliminates that weak point and gives you a more dependable setup.
At MDS of Michigan, we see it all the time: the right locking style can turn a constant maintenance issue into a solved problem. If you are unsure which size or insert bearing is right for your application, Click Here to contact us today!
