Widely used in high-speed, high-precision and compound load equipment, such as machine tool spindle, motor rotor, automobile gearbox, helicopter transmission system, precision instruments (such as centrifuges) and so on.

• 1.P5:High Precision P4:Ultra-High Precision P6:Normal precision DB=back-to-back pairing，two bearings
• 2.It can bear radial+unidirectional axial load at the same time, making up for the defect of weak axial load of deep groove ball bearings.
• 3.Excellent high-speed performance, small friction coefficient and high running accuracy.
• 4.A single bearing can only bear one-way axial force, and if it needs two-way bearing, it needs to be installed in pairs (such as back-to-back, face-to-face and series arrangement).
• 5.Pay attention to the matching method when installing, and control the pre-tightening force (too tight is easy to heat up, too loose affects the accuracy); Maintenance requires regular replenishment of clean grease to avoid the invasion of impurities and prolong the service life.
