Product Overview of Ball Bearings

・ Deep groove ball bearing is the most commonly used rolling bearing. It is of simple structure and easy to use.
・ This kind of bearing has small friction coefficient and high limit speed.
・ The material of this bearing is equivalent to SUS440C, which has a certain antirust ability.
・ The noise level of this bearing reaches Z1.

Product Feature of Ball Bearings

・ The interface radius of the channel located on the inner and outer ring is slightly larger than the radius of the sphere, in arc shape. Mainly can bear radial load.
・ In addition to the open type bearings, there are Ball Bearings with steel dust cover, bearings with contact rubber seal packing and bearings with non-contact rubber seal packing, or bearings with stop ring on the outer diameter of outer ring.
・ Ball bearings with dust cover or seal packing are sealed with proper amount of high-quality grease. Deep groove ball bearings generally adopt steel plate stamped cage, which has low friction torque and accuracy grade of 0.

Precautions for Using Ball Bearings

When the precision of the shaft and Ball Bearings housing is poor, the ball bearings will be affected, and its due performance will not be exerted. For example, the poor precision of the mounting part with the bearing will cause relative inclination of the inner and outer rings. At this time, besides the bearing load, the edge load will be increased additionally, which will shorten the fatigue life of the bearing, and even more seriously, it will lead to damage such as cage breakage and sticking.

Please use the following special mounting tool for installation and removal

Bearing heater	Proper installation of the Ball Bearings heater can guarantee a long life of the Ball Bearings. Rolling bearings are reliable mechanical components with long service life if they are installed and maintained correctly. After the induction heater is used for heating, the bearing expands outward in the cylindrical direction, which can avoid the damage during installation. Induction heater is one of the most scientific heating methods, which does not need preheating, and can be heated to 110℃ in a few seconds or minutes depending on the weight of bearings, without damaging the prior lubrication

Bearing puller	When the installation state of the Ball Bearings is in the following situations, the special puller can be used for disassembly. (a) Shaft shape: cylindrical shaft, Inner diameter shape of bearing inner ring: cylindrical hole. (b) Shaft shape: cylindrical shaft, inner diameter shape of bearing inner ring with tight bushing: tapered hole. (c) Shaft shape: tapered shaft, Inner diameter shape of bearing inner ring: tapered hole. In either state, the lock nut of the shaft (or the lock nut of the tight bushing) must be released during disassembly, and the lock nut must be placed in a loose state.
