Introduction



6021 ZZ Bearing has good impact toughness and fracture toughness. When the it is subjected to a large local load during operation, a large contact stress will be generated between the ball and the ring, so the requirements for bearing steel are very high. The steel ball material used in our products is GCr15, which conforms to the GB/T 308.1-2013 standard. GCr15 is the most widely used bearing steel. It has high hardness, wear resistance and sufficient strength. It also has some toughness and corrosion resistance. Numerous advantages make it the perfect partner for bearings. Bearings are widely used in home appliances, instrumentation, roller skates, industrial pumps, gearboxes, tractors and other fields.


Sealing



Sealing is to prevent dust, water and other debris from entering the 6021 ZZ Bearing and prevent lubricant loss. There are two types of seals: external seals and integrated seals. Among them, the external seal can be divided into non-contact type and contact type according to factors such as the use environment. The non-contact outer seal does not directly contact the shaft, so there is no friction and wear, and it is suitable for high-speed rotation. The sealing performance of the contact external seal is better than that of the non-contact seal, but the friction force is large and the temperature rise is relatively high. The contact area between the shaft and the sealing ring needs to be lubricated, usually with the same lubricant as the bearing. In addition to using various oil seals, Z-type/V-type seals can also be used for sealing.
