Are you tired of premature bearing failure costing you time and money? The NTN 62112-2RS deep groove sealed bearing might just be the unsung hero you need. This article will cut through the jargon and show you how this specific bearing tackles three key challenges in demanding applications. We’ll also explore some unconventional insights I’ve gained from my years of experience, so you get practical advice you won’t find anywhere else.
Deep groove ball bearings are workhorses, but the NTN 62112-2RS takes it a step further with its sealed design. This means better protection against contaminants, extending the bearing’s lifespan significantly. What does that mean for you? Less downtime, reduced maintenance costs, and increased productivity.
What Makes the 62112-2RS Special?
It’s all about that seal! The “2RS” designation indicates a rubber seal on both sides of the bearing. This seal is crucial in preventing dirt, dust, and moisture from entering the bearing, which can cause premature wear and failure. Think of it as a tiny bodyguard constantly protecting the internal components. The specifications are standard for a bearing of this type: 60mm bore, 110mm outside diameter, and 22mm width.
Problem 1: Contamination Catastrophes and NTN 62112-2RS to Rescue
The number one killer of bearings is contamination. Period. In dirty or dusty environments, particles can get inside the bearing, grinding away at the balls and races, leading to increased friction, heat, and ultimately, failure. The NTN 62112-2RS’s seals create a barrier, significantly reducing the risk of contamination.
Real-World Application: Agricultural Equipment
Imagine a combine harvester working in a dusty field. Without proper sealing, the bearings in the wheels and cutting mechanisms would quickly fail. The NTN 62112-2RS is a common choice in these applications because its seals stand up to the harsh conditions. I’ve seen firsthand how switching to sealed bearings like this one can dramatically extend the life of agricultural equipment, saving farmers thousands of dollars in repairs and downtime.
Problem 2: Grease Loss and the NTN 62112-2RS Solution
Proper lubrication is vital for bearing life, but grease can leak out over time, especially at higher operating temperatures or in vibrating applications. The “2RS” seals in the NTN 62112-2RS not only keep contaminants out but also help retain the grease inside the bearing.
First-Hand Experience: Electric Motors
I once worked on a project involving electric motors used in a food processing plant. The motors were constantly exposed to washdown procedures, and the bearings were failing frequently due to grease washout. Switching to NTN 62112-2RS bearings drastically reduced the grease loss and extended the motor’s service life. We went from replacing bearings every few months to only needing to replace them every year or two.
Problem 3: Premature Wear and Tear: The NTN 62112-2RS Advantage
Contamination and grease loss lead to premature wear and tear, which can cause a cascade of problems, including increased vibration, noise, and ultimately, catastrophic failure. By addressing these issues, the NTN 62112-2RS extends the bearing’s lifespan, reducing the frequency of replacements and minimizing downtime.
Innovative View: Proactive Maintenance
Don’t wait for your bearings to fail before taking action. Consider implementing a proactive maintenance program that includes regular inspection and replacement of bearings, even if they haven’t shown signs of failure. This is especially important in critical applications where downtime can be extremely costly. While it might seem expensive upfront, a properly scheduled maintenance prevents much larger problems.
NTN is a reputable bearing manufacturer known for its high-quality products. The NTN 62112-2RS is made from high-quality steel and manufactured to precise tolerances, ensuring smooth operation and long life.
Material Matters: The Steel Advantage
The quality of the steel used in the bearing’s construction significantly impacts its performance and lifespan. NTN uses high-quality steel that is heat-treated to provide optimal hardness and wear resistance.
Precision Manufacturing: Tolerances and Performance
Bearings are precision components, and even small deviations from the specified tolerances can affect their performance. NTN’s manufacturing processes ensure that the NTN 62112-2RS meets the required tolerances for smooth operation and long life.
Why NTN Stands Out from the Crowd
NTN Corporation is a global leader in bearing manufacturing, with a long history of innovation and quality. Their commitment to research and development ensures that their bearings meet the demands of modern applications.

From my years of experience, I’ve learned that choosing the right bearing involves more than just matching the size and type. Here are some unique insights to consider:
The “Feel” Test: A Quick Check for Quality
Before installing a new bearing, I always give it the “feel” test. Rotate the bearing in your hand and feel for any roughness or binding. A high-quality bearing should rotate smoothly and quietly. If you feel any resistance or hear any noise, it could indicate a defect, and the bearing should be replaced.
Temperature Matters: High-Temp Grease
In high-temperature applications, standard grease can break down and lose its lubricating properties. Consider using a high-temperature grease specifically designed for bearings to ensure proper lubrication and extend bearing life.
Load Capacity and NTN 62112-2RS
While the NTN 62112-2RS is a robust bearing, it’s essential to ensure that it can handle the load requirements of your application. Consult the manufacturer’s specifications to determine the bearing’s load capacity and ensure that it is adequate for your needs.
The NTN 62112-2RS is an excellent choice for applications where contamination and grease loss are concerns. Its sealed design, high-quality materials, and precise manufacturing make it a reliable and long-lasting bearing.
