Oil seals are essential to keep lubricants and other necessary substances inside rotating shaft equipment and prevent debris from entering. NSAR has more than 20 years of experience in oil seal and bearing production. Contact us to order your bearings.

An oil seal is a rotating shaft seal used to seal the gap between the stationary and moving parts to prevent lubricant from escaping, thereby blocking contaminants in the gap. Different types of oil seals are suitable for different applications and environments and are made of different materials. The correct material and type of oil seal depends on the application and media of the oil seal.

Not all bearings are built the same. Rolling ball bearings are great for many applications, but when things get tough—misalignment, heavy loads, constant vibration—you need something stronger.Ready to buy some bearings? Contact us at NSAR today.

When you think of bridges, bearings might not be the first thing that comes to mind. But these small (sometimes hidden) components play a huge role in keeping bridges safe. Whether it’s a massive suspension bridge spanning a river or a simple overpass, bearings are crucial to handling the forces bridges face everyday.

Bearings might look simple but they’re exact components. Every part, every tiny detail, plays a role in keeping your machinery running smoothly. One of those critical details? Clearance.
It’s not just a technicality—it’s the difference between a bearing that works flawlessly and fails catastrophically.

Bearings might be small, but they do a big job. They keep your machinery moving smoothly and support heavy loads. Reach out to us at NSAR for high-quality bearings, fast shipping, and expert support. Let’s keep your machinery—and your business—running smoothly around the clock.
