The 6805ZZ deep groove ball bearing is a critical component in the deep groove ball bearing series, renowned for its excellent comprehensive performance in medium and large mechanical transmission systems. With dimensions of 25mm inner diameter, 37mm outer diameter, and 7mm thickness, this bearing optimally balances structural compactness with load-carrying capacity.
Ideal for applications with space constraints and transmission efficiency requirements, the 6805ZZ provides robust support for stable equipment operation across industrial machinery, automated production lines, precision instruments, ventilation equipment, medical devices, and office equipment.
Features high-strength steel balls with precision processing, ensuring excellent surface smoothness and dimensional tolerance control. The deep groove raceways of inner and outer rings are optimally designed to form perfect contact with steel balls, enabling uniform force distribution and efficient radial load handling with additional axial load capacity.
The "ZZ" designation indicates double-sided metal dust covers that provide effective protection against dust, water vapor, and contaminants. This sealing structure preserves the high-performance internal grease, extends lubrication cycles, and reduces maintenance requirements.

Pre-filled with high-performance grease at factory. Under harsh conditions (high temperature, humidity, dust), regularly inspect grease condition and replace if dried, discolored, or contaminated.
Establish inspection schedule to check dust cover integrity and monitor vibration/temperature. Normal operating temperature is typically 10-20°C above ambient temperature.
Install in clean environment using proper tools and methods. Ensure precise fit with shaft and housing, avoiding impact damage during installation.
