The 7318BMU angular contact ball bearing is a precision-engineered component designed for demanding electrical and mechanical applications, featuring a 90 mm bore, 190 mm outer diameter, and 43 mm width for robust performance in compact spaces. Constructed from high-grade bearing steel, it offers a dynamic load rating of 148,000 N and a static load rating of 124,000 N, ensuring reliable operation under heavy radial and axial loads. The bearing operates efficiently at high speeds, with a maximum grease-lubricated speed of 2,400 rpm and oil-lubricated speed up to 3,700 rpm. Its single-row design, brass cage, and C3 radial clearance provide smooth rotation, reduced friction, and extended service life, making it ideal for industrial machinery, motors, and high-precision equipment where durability and accuracy are critical.
