01. Optimized for High-Speed and Quiet Operation

Precision-manufactured components and a rigid pressed steel cage ensure consistent, quiet operation with minimal vibration. With limiting speeds up to 19,000 r/min, this bearing supports stable performance in sensitive devices like electric motors and precision instruments where low noise is critical.

02. Robust Design with Balanced Load Capacity

Conforming to the popular 63-series medium section, the 15×42×13 mm configuration delivers a dynamic load rating of 11.4 - 14.3 kN. This robust construction ensures reliable performance in applications where both radial and axial forces are present.

03. Effective Contaminant Exclusion

Double Z-type non-contact steel shields provide a reliable barrier against dust, dirt, and other airborne particulates from both sides. This design helps retain lubricant integrity and significantly extends the operational life of the bearing in harsh environments without introducing significant rotational drag.

Design & Configuration

The 6302 ZZ is furnished with double Z-type steel shields as standard, delivering enhanced internal protection in dusty or debris-prone industrial conditions. For applications requiring a hermetic seal against moisture or finer contaminants, the double rubber-sealed variant (6302 2RS) is also available. For applications involving higher operating temperatures or shaft expansion, a C3 internal clearance variant (6302 ZZ C3) can be supplied.

"The 6302 ZZ is a versatile workhorse for electric motors and industrial drives, combining reliable load capacity with effective contamination protection for long-term, maintenance-free operation."
