One key feature of the 6202 ZZ High Speed Bearing is its advanced sealing technology. It uses a double shielded design that effectively seals out dirt and contaminants to ensure smooth operation and long life.

Another notable aspect of this bearing is its high load-carrying capacity. It has a dynamic load rating of 12.4 kN and a static load rating of 6.5 kN, making it ideal for heavy-duty applications. Additionally, the bearing is precision machined to ensure optimal fit and rotation, reducing vibration and noise.

In terms of construction, the 6202 ZZ High Speed Bearing is made from high-grade materials that offer superior strength and durability. The inner and outer rings are made from chrome steel, which is heat treated and hardened for maximum toughness and wear resistance. The balls are made from hardened steel, while the cage is made from reinforced nylon to provide reliable performance over the long term.

Finally, the 6202 ZZ High Speed Bearing is easy to install and maintain. It has standard dimensions of 15mm bore, 35mm outer diameter, and 11mm width, making it easy to find compatible replacements. It also has a lifespan of over 20,000 hours under normal operating conditions, reducing the need for frequent replacements.

Overall, the 6202 ZZ High Speed Bearing is an excellent choice for merchants looking for high-quality, dependable bearings for their customers. With its advanced sealing technology, high load-carrying capacity, and precision construction, it's sure to provide reliable performance even in the toughest applications.

● Introduction

6202 ZZ high speed bearing is single row deep groove bearings. Deep groove ball bearings have a simple structure and don't have to be maintained during operation, and they are low-cost and widely used bearings. The steel balls conform to the standard GB/T 308.1-2013, the material of steel balls is GCr15, and the grade of steel balls is 10. The steel balls are quenched to meet the requirements of strength, hardness, wear resistance and contact fatigue strength, and are tempered to obtain good elasticity, toughness and dimensional stability and other comprehensive mechanical properties. Deep groove ball bearings are mainly used to bear radial load, but also commonly used to bear radial and axial combined load. Especially when the speed of mechanical equipment is very high, it is not suitable to use thrust bearing, the bearing can be used to bear double directions axial load. Bearings are widely used in instruments, automated office machinery, textile machinery, construction machinery, roller skates and other fields.

● Production Details

Resin bonded grinding wheels are used, and thin-walled cylindrical, 80# grit grinding wheels are used for single face grinding, 80# grit grinding wheels with large air holes are used for double end face grinding. The grinding dosage includes table speed and wheel feed, which is related to the outer diameter of the collar and the number of pieces (for single-face grinding) or the width of the collar (for double-endface grinding). The factors that produce cracks in the collar upsetting process are the combination of the length-to-diameter ratio of the material section itself and the diameter of the bar stock. The same diameter of the bar and shear conditions, when the length to diameter ratio is less than a certain value, it will produce such cracks. This is mainly due to the strengthening of the shear effect and weakening of the bending effect, which increases the deformation of the deformation zone. When upsetting can be before upsetting, a stress relief annealing of the material section, annealing temperature of 560 ℃, holding time of 5 ~ 7h, in order to eliminate the residual stress on the surface of the crack, to improve its plasticity. In this way, the front end of the crack can undergo a certain degree of solitary deformation during upsetting deformation, the stress will have a certain degree of relaxation, and the stress field will change to stop the expansion of the crack.

● Technical Parameters

The standard of boundary dimensions is ISO 15: Rolling bearings - Radial bearings - Boundary dimensions, general plan.

● Bearing Tolerance and Radial Clearance

Shaft rotation accuracy is mainly related to the running accuracy of the bearing and the positioning accuracy of the bearing, using radial bearing or angular contact bearing to do the bearing (except for non-radial positioning), the bearing inner ring and shaft, outer ring and shell hole should be interference. This can ensure the radial positioning accuracy of the bearing, and prevent the inner ring and shaft, outer ring and shell hole sliding and wear, but also to ensure that the inner and outer ring and the support surface of the overall uniform fit. The amount of interference between the mating surfaces is changing after assembly and during work, the greater the deformation caused by force and temperature difference, the greater the change in the amount of interference.

● Noise Level and Vibration Level

The standard of noise level is JB/T 7047: Noise level measuring with the instrument S0910.

The standard of vibration level is JB/T 10187: Vibration level measuring with the instrument BVT.
