Comparing Ball Bearing 6204 with Other Bearing Types

Ball Bearing 6204 vs. Other Common Ball Bearings

Ball Bearing 6204 shares similarities with other ball bearings but has unique characteristics:

1. 6203 Bearing: Smaller than 6204, with a 17mm bore. Used in lighter applications.
2. 6205 Bearing: Larger than 6204, with a 25mm bore. Suitable for heavier loads.
3. 608 Bearing: Smaller overall, often used in skateboards and inline skates.
4. 6000 Series: 6204 is part of this series, which includes bearings of various sizes.

Compared to these, 6204 offers a balance of size and load capacity. It’s more versatile than smaller bearings like 608, but not as heavy-duty as larger ones like 6205.

The choice between these bearings depends on specific application requirements. Factors like load, speed, and space constraints guide the selection process.

Comparing Dimensions and Materials

Dimensions and materials play a crucial role in bearing selection:

1. Dimensions:
   • 6204: 20mm bore, 47mm OD, 14mm width
   • 6203: 17mm bore, 40mm OD, 12mm width
   • 6205: 25mm bore, 52mm OD, 15mm width
2. Materials:
   • Most common: Chrome steel
   • Alternatives: Stainless steel, ceramic

6204 sits in the middle range for size. This makes it suitable for a wide range of applications. Its dimensions allow for good load capacity without being too bulky.

Material choice affects performance and durability. Chrome steel is standard, offering good strength and wear resistance. Stainless steel provides better corrosion resistance, while ceramic offers high-speed capabilities.

Comparing Performance and Durability

Performance and durability vary among bearing types:

1. Load capacity:
   • 6204 handles moderate loads well
   • Larger bearings like 6205 can take heavier loads
   • Smaller ones like 6203 are better for lighter applications
2. Speed ratings:
   • 6204 performs well at high speeds
   • Ceramic versions can handle even higher speeds
3. Durability:
   • Depends on material, lubrication, and operating conditions
   • 6204 offers good durability in proper conditions
   • Sealed versions last longer in contaminated environments
4. Temperature resistance:
   • Standard 6204 works well in normal temperature ranges
   • Special versions available for extreme temperatures

Overall, 6204 offers a good balance of performance and durability. It outperforms smaller bearings in load capacity and matches larger ones in speed capabilities.
