Detailed Engineering Specifications

Manufactured under strict quality controls, this deep groove ball bearing features an 81mm inside diameter, a 127mm outside diameter, and an 18mm width. Constructed from high-grade polycarbonate, it provides exceptional resistance to many chemicals, corrosive substances, and moisture, making it suitable for environments where traditional steel bearings would degrade. Its inherent non-magnetic properties and low coefficient of friction contribute to smooth operation and extended service life in low-load applications. The robust polymer construction ensures a lightweight solution without compromising structural integrity for its intended use.
