There are wide inner ring bearing to the heart of the spherical and with locking device. Mainly for simple shell. Linear motion bearings: two raceways in the rolling direction of the rolling bearing relative linear movement. Ball bearings: rolling body is ball bearing. : Each ring has a cross-section of about a third of the circumference of the ball continuous groove type raceway radial ball bearings for precision instruments, low noise motors, automobiles, motorcycles and general machinery, the machinery industry, the most widely used class of bearings. Simple structure, easy maintenance. Mainly used to bear radial load, but also bear certain axial load, when the bearing radial clearance increased, with angular contact ball bearings can bear large axial load. This kind of bearing friction coefficient is small, extreme high speed, size range and diverse. Solid and durable injection molding machine bearings 51222, versatility and low noise operation, can operate at high speed and ease of installation. Single row deep groove ball bearings otherwise seal design, no need for lubrication and maintenance-free. Single row with filling gaps and double row ball bearing, suitable for heavy conditions.
