Review CLEVITE Main Bearing Set Ms979p
The **Clevite MS-979P Bearing Set** is a high-performance, precision-engineered component designed to deliver exceptional durability, smooth operation, and reliability in demanding mechanical applications. Part of Clevite s renowned line of sealed ball bearings, this set features a robust **6000 series chrome steel ball bearing** with a robust outer ring and a high-quality inner ring, both machined to tight tolerances for minimal friction and optimal load distribution. The bearing is sealed with a **dual-lip rubber shield** that effectively prevents the ingress of contaminants such as dust, dirt, and moisture, ensuring prolonged service life even in harsh or unprotected environments. This sealing system also retains lubrication within the bearing, reducing the need for frequent maintenance and extending operational efficiency.
Constructed from **high-carbon chromium steel**, the MS-979P bearing set is heat-treated to achieve a hardness of approximately **60-64 Rockwell C**, providing superior resistance to wear, fatigue, and deformation under heavy loads. The bearing s **ball-and-race design** allows for smooth rotational movement with minimal energy loss, making it ideal for applications requiring precision and consistency, such as automotive wheel hubs, industrial machinery, agricultural equipment, and marine systems. The **standard bore size of 1.75 inches (44.45 mm)** and **outer diameter of 3.125 inches (79.38 mm)** ensure compatibility with a wide range of shafts and housings, while the **0.375-inch (9.53 mm) width** strikes a balance between stability and compactness.
What sets the Clevite MS-979P apart is its **versatility and engineering precision**, making it a trusted choice for both OEM manufacturers and maintenance professionals. Whether used in automotive wheel hubs, conveyor systems, or heavy-duty machinery, this bearing set is engineered to withstand axial and radial loads with ease, reducing vibration and extending the lifespan of connected components. Its **sealed construction** eliminates the need for grease fittings or frequent relubrication, simplifying installation and maintenance while maintaining peak performance under varying operational conditions. For applications where reliability and longevity are critical, the Clevite MS-979P bearing set delivers a proven solution built to endure the rigors of continuous use.
**Pros and Cons of buying a Clevite MS-979P Bearing Set (MS979P)**
The Clevite MS-979P is a ball bearing designed for applications such as alternators, water pumps, and other automotive components. Below is a detailed breakdown of its advantages and disadvantages.
### **Pros**
1. **High Quality and Durability** Clevite is a well-known brand in the automotive industry, known for producing reliable bearings that withstand heavy loads and high speeds. The MS-979P is designed to handle demanding conditions, such as those found in alternators and water pumps, where consistent performance is critical.
2. **Compatibility with Common Applications** This bearing is specifically engineered for use in alternators, power steering pumps, and other automotive components where a 1-inch bore and 1.5-inch outer diameter are standard. Its dimensions make it a direct replacement for many OEM (Original Equipment Manufacturer) bearings, reducing the risk of fitment issues.
3. **Sealed Construction** The MS-979P features a sealed design, which helps protect the internal components from contaminants like dust, dirt, and moisture. This extends the bearing s lifespan and reduces the need for frequent maintenance or premature failure.
4. **Cost-Effective Alternative to OEM** While not always the cheapest option, the MS-979P often provides a balance between affordability and performance compared to aftermarket alternatives. It is typically priced lower than some high-end or premium bearings while still offering reliable service.
5. **Easy Installation** The bearing is designed for straightforward installation, often requiring minimal tools. Its standard dimensions make it compatible with common mounting systems, reducing the complexity of replacement procedures.
6. **Widely Available** Due to its popularity in automotive repairs, the MS-979P is readily available through auto parts stores, online retailers, and specialty bearing suppliers. This ensures easy access for DIY enthusiasts and professional mechanics alike.
7. **Good Load-Bearing Capacity** The bearing is rated to handle radial and axial loads effectively, making it suitable for applications where vibration and stress are common. This contributes to smoother operation and reduced wear on connected components.

### **Cons**
1. **Limited to Specific Applications** While versatile, the MS-979P is not a universal bearing. It is optimized for alternators, water pumps, and similar components with matching dimensions. Attempting to use it in non-compatible applications (e.g., wheel bearings or heavy machinery) could lead to poor performance or failure.
2. **Potential for Counterfeit Products** Like many popular automotive parts, the MS-979P may be subject to counterfeit or low-quality imitations, particularly when purchased from untrusted sellers. Counterfeit bearings may fail prematurely or lack the durability of genuine Clevite products, leading to costly repairs.
3. **Noise or Vibration in Some Cases** While rare, some users report slight noise or vibration when the bearing is new or improperly installed. This is often temporary as the bearing bedded in, but poor installation or contamination can exacerbate the issue. Proper lubrication and alignment are essential to mitigate this.
4. **Price Variability** The cost of the MS-979P can vary significantly depending on the seller. While it is generally affordable, purchasing from discount or unknown suppliers may result in overpricing or subpar quality. Always compare prices and reviews before making a decision.
5. **Requires Proper Lubrication** Like all bearings, the MS-979P relies on adequate lubrication to function optimally. Failure to use the correct lubricant (e.g., grease or oil) or over-lubrication can lead to overheating, increased friction, or premature wear. Users must follow manufacturer guidelines for maintenance.
6. **Not Suitable for Extreme Conditions** While durable, the MS-979P is not designed for extreme environments such as high-temperature industrial applications or exposure to corrosive chemicals. In such cases, specialized bearings may be required.
7. **Installation Skill Dependency** While the bearing itself is easy to install, improper handling during removal or installation (e.g., using excessive force or incorrect tools) can damage the bearing or its housing. Users without mechanical experience may need to seek professional assistance to avoid mistakes.

### **Conclusion**
The Clevite MS-979P bearing set is a reliable and widely used component for automotive applications such as alternators and water pumps. Its sealed design, durability, and compatibility with common systems make it a practical choice for both DIY repairs and professional use. However, its suitability is limited to specific applications, and potential buyers should ensure they are purchasing a genuine product from a reputable source. Proper installation and maintenance are key to maximizing its lifespan and performance.
### **Recommendation**
If you are replacing a bearing in an alternator, water pump, or similar automotive component that requires a 1-inch bore and 1.5-inch outer diameter, the Clevite MS-979P is a strong and cost-effective option. To ensure the best results:
- **Verify compatibility** with your specific application by checking the bearing s dimensions and load ratings.
- **Purchase from trusted suppliers**, such as RockAuto, Amazon (with verified seller ratings), or local auto parts stores with good reputations, to avoid counterfeit products.
- **Follow proper installation procedures**, including cleaning the mounting surfaces and applying the correct lubricant.
- **Monitor performance** after installation, addressing any unusual noise or vibration promptly.
For users with limited mechanical experience, consulting a professional mechanic may be advisable to confirm fitment and installation. Overall, the MS-979P is a dependable choice for its intended use, provided it is sourced and installed correctly.
