Specified by design engineers worldwide, this 21mm bore x 161mm OD x 12mm width deep groove ball bearing is constructed from high-grade carbon steel, prized for its excellent hardness, wear resistance, and tensile strength. This material composition ensures prolonged service life under demanding operational conditions and moderate shock loads. The bearing's design is optimized for high-speed rotation and the accommodation of both radial and axial loads, making it a critical component in various power transmission assemblies requiring low friction and high efficiency.
This component strictly adheres to the tolerances, material specifications, and quality benchmarks set by the world's leading industrial manufacturers.
1. Ensure the bearing housing and shaft are clean and free from contaminants. 2. Apply a thin, uniform layer of appropriate lubricant to the shaft and inner ring raceway. 3. Carefully press the bearing onto the shaft, ensuring it seats squarely and without excessive force, or utilize a controlled press-fit method.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect lubricant or insufficient lubrication. | Consult the bearing manufacturer's recommendations for the specific lubricant type and application method to ensure optimal performance and lifespan. |
| Applying excessive force during installation, leading to brinelling or shaft deformation. | Utilize a proper bearing installation tool or controlled press-fit procedures. Never hammer directly on the bearing rings. |
