The most prominent advantage of the 1B series lies in its unique four-point contact raceway structure. Precision-manufactured steel balls form four-point contact with the heat-treated raceway surfaces, enabling the bearing to withstand axial load, radial load and overturning moment simultaneously. This composite load capacity greatly surpasses that of ordinary single-direction ball bearings, ensuring smooth and stable rotary operation under complex alternating working conditions. The integrated external gear on the outer ring features precise tooth profile processing, which can directly mesh with driving pinions to realize efficient power transmission. This integrated gear design omits intermediate transmission accessories, effectively simplifies the overall mechanical structure, reduces assembly errors, and improves the transmission efficiency of the complete equipment.

In terms of material and processing technology, 1B series bearings adopt high-quality structural alloy steel for bearing rings and high-precision bearing steel for rolling elements. The raceway and gear tooth surfaces undergo strict integral quenching and local high-frequency hardening treatment, achieving high surface hardness and excellent wear resistance, which effectively avoids surface abrasion, peeling and fatigue damage during long-term cyclic operation. Equipped with standardized double-sided rubber sealing devices, the bearings can effectively isolate dust, moisture, muddy water and other pollutants in the working environment, prevent internal lubricating grease from volatilizing and leaking, and maintain a stable internal lubrication state, thus significantly extending the service life of the product.
