Engineered for reliability and performance, this deep groove ball bearing boasts a 21mm inside diameter, a substantial 136mm outside diameter, and a compact 9mm width. Constructed from high-grade brass, it exhibits excellent thermal conductivity and superior resistance to corrosive environments, outperforming standard steel bearings in specific applications. This material choice also minimizes potential issues with stray electrical currents. The precise internal geometry and ball complement ensure low friction, high rotational speeds, and significant radial and axial load-carrying capacity, vital for efficient power transmission in demanding industrial settings.
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 light coat of appropriate lubricant to the shaft and the bearing's inner ring. 3. Carefully press the bearing onto the shaft using a bearing press or appropriate tooling, applying even pressure to the inner ring only.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Applying excessive force to the outer ring during shaft mounting. | Always apply mounting force to the inner ring when installing on a shaft to prevent damage to the bearing raceways and balls. |
| Using incorrect lubrication for the operating environment. | Consult the application requirements and lubricant compatibility charts to select a lubricant that provides adequate protection for the brass bearing and operating conditions. |
