Are you struggling with premature bearing failure or inconsistent performance from your INA 63320-2RS deep groove sealed bearings? This article provides five proven solutions to extend the life and enhance the reliability of these critical components, addressing common issues and offering practical, experience-based advice you won’t find anywhere else. This article solves 3 problems: selecting the right bearing, installatinos tips and optimal maintainence.
Let’s face it, bearings aren’t exactly the most glamorous part of any machine, but they’re absolutely essential. The INA 63320-2RS is a workhorse. It’s a deep groove ball bearing, sealed on both sides (that’s the 2RS), and made by INA, a reputable manufacturer. You’re likely using it in a situation where you need to minimize friction and handle both radial and axial loads. It’s the kind of component you only think about when it fails, right? The goal is to ensure this isn’t the case.
Why Choose the INA 63320-2RS?
- Versatility: Suitable for various applications, from electric motors to agricultural machinery.
- Sealed Design: Protects against contaminants, extending bearing life.
- Reliability: INA is known for producing high-quality, durable bearings.

Proper installation is paramount. A ham-fisted approach can easily damage a new bearing, setting it up for premature failure. Think of it like this: you wouldn’t force a puzzle piece, would you?
Avoiding Common Installation Mistakes
- Never Hammer Directly: This is bearing abuse 101. Always use a bearing installation tool or a sleeve that contacts the inner race. This prevents force from being transmitted through the balls and races, which can cause indentations (brinelling).
- Ensure Alignment: Misalignment puts undue stress on the bearing. Use shims or precision measuring tools to guarantee the shaft and housing are perfectly aligned.
- Controlled Press Fits: For press fits, use an arbor press or hydraulic press. Apply force slowly and evenly. Listen for any unusual noises, which could indicate binding or damage.
My Personal “Oops” Moment (and What I Learned)
I once rushed an installation on a piece of farm equipment (a seed drill, to be exact). I didn’t have the proper sized sleeve and thought I could “get away with it” using a socket. Big mistake! The bearing failed within a few hours of operation. Now, I always double-check my tools and never compromise on proper installation techniques. This mistake probably cost the farm several hundred dollars when adding the cost of the down time.
The “2RS” designation means it’s sealed, right? So, no need to worry about lubrication? Wrong! While the seals keep contaminants out, the factory grease will eventually degrade.
Choosing the Right Grease
- Consider the Operating Environment: High temperatures, moisture, and heavy loads all dictate the type of grease you should use. A lithium-based grease is a good general-purpose choice, but for extreme conditions, consider a synthetic grease with higher temperature and load-carrying capabilities. (See: https://en.wikipedia.org/wiki/Grease_(lubricant))
- Compatibility is Key: If you’re replacing a bearing, try to use the same type of grease that was originally used. Incompatible greases can react and form harmful deposits.
- Don’t Over-Grease: More isn’t always better. Over-greasing can create excessive pressure within the bearing, damaging the seals.
A Trick From the Pros
For bearings in extremely dirty environments, consider using a grease with solid additives like molybdenum disulfide (MoS2). These additives provide a layer of protection even if the grease is washed away.
Don’t wait for a catastrophic failure. Implement a regular inspection and maintenance schedule. This is a preventative approach and will reduce downtime in the long run.
Establishing a Maintenance Schedule
- Visual Inspections: Regularly check for signs of damage, such as cracks, rust, or discoloration. Listen for unusual noises (grinding, squealing) during operation.
- Temperature Monitoring: Excessive heat is a sign of friction and potential bearing failure. Use an infrared thermometer to monitor bearing temperatures.
- Vibration Analysis: For critical applications, consider using vibration analysis equipment to detect early signs of bearing wear. This is a bit more advanced but can save you from larger costs in the long run.
How to “Listen” to Your Bearings
Get a mechanic’s stethoscope (they’re inexpensive) and carefully touch it to the bearing housing while the machine is running. You’ll be surprised at how much you can hear! A healthy bearing will sound smooth and consistent. A worn bearing will sound rough, gritty, or even have a high-pitched whine.
Bearings have limits. Exceeding these limits significantly reduces their lifespan. Know the capabilities of your INA 63320-2RS.
Matching the Bearing to the Application
- Load Ratings: Check the bearing’s static and dynamic load ratings. Ensure the bearing can handle the maximum load it will experience during operation. (https://en.wikipedia.org/wiki/Bearing_(mechanical)#Load_ratings)
- Speed Limits: Exceeding the bearing’s speed limit can cause excessive heat and premature failure.
- Operating Conditions: High temperatures, corrosive environments, and exposure to contaminants all affect bearing life.
Practical Load & Speed Table Example
| Factor | Consideration | Mitigation |
|---|---|---|
| Excessive Load | The bearing experiences loads beyond its specified rating. | Use a bearing with a higher load rating, redistribute the load, or reduce the applied load. |
| High Speed | The bearing operates at speeds exceeding its permissible limit. | Use a bearing designed for higher speeds, reduce the operating speed, or improve lubrication. |
| Misalignment | Angular or parallel misalignment causing uneven load distribution. | Ensure proper alignment during installation and operation, use self-aligning bearings, or adjust components. |
| Vibration | Excessive vibration leading to premature wear and failure. | Dampen vibrations, balance rotating components, and use vibration-resistant bearings. |
Sometimes, even with the best care, a bearing reaches the end of its life. Choosing a quality replacement is crucial.
Selecting a Replacement Bearing
- Stick with Reputable Brands: INA, SKF, FAG – these are all known for quality and reliability. Don’t be tempted by cheap, no-name brands. You’ll likely regret it.
- Consider Upgrades: If you’re constantly replacing bearings, consider upgrading to a bearing with better seals, higher load ratings, or a different internal design.
- Verify Authenticity: Counterfeit bearings are a real problem. Purchase bearings from authorized distributors to ensure you’re getting a genuine product.
My Recommendation: A Little Extra Investment Goes a Long Way
I’ve seen the difference firsthand between cheap bearings and quality bearings. The initial cost might be higher, but the longer lifespan and reduced downtime more than make up for it in the long run. It’s like buying a good pair of boots – they might cost more upfront, but they’ll last for years and save you money in the long run. When it comes to a INA 63320-2RS deep groove sealed bearing, always aim for the best that will fit your budget.
| Brand | Reputation | Cost | Strengths | Weaknesses |
|---|---|---|---|---|
| INA | High | Medium | High precision, durable, reliable | Can be hard to find in some areas |
| SKF | High | High | Wide availability, innovative technology, premium quality | Higher cost |
| FAG | High | Medium | Similar to INA, reliable and durable | Fewer specialized options compared to SKF |
| Timken | High | Medium to High | Excellent for heavy-duty applications | Primarily focused on tapered roller bearings |
This comprehensive guide, packed with practical advice and personal insights, should help you extend the life and improve the performance of your INA 63320-2RS deep groove sealed bearings. Good luck!
