22208CAW33

22208CA/W33 is a spherical roller bearing with CA type brass cage, which is one of the most widely used general-purpose spherical roller bearings. It has a stable overall structure, is precision-machined from high-carbon chromium bearing steel and undergoes multiple processes such as quenching and grinding, ensuring extremely high dimensional accuracy and rotational precision. With strong rigidity and reasonable design, this bearing has the core advantages of excellent self-aligning function, which can compensate for installation coaxiality deviation. It can also bear large radial load and a certain axial load, with outstanding impact resistance, moderate friction coefficient, stable and reliable operation. Equipped with W33 annular oil groove, it is convenient for lubrication and has good heat dissipation. It also has the characteristics of wear resistance, corrosion resistance and easy maintenance, making it one of the core bearing types for bearing heavy load and dealing with eccentric working conditions in the industrial field, widely used in various heavy-load transmission scenarios.

Application Scope: It is widely used in various fields such as general machinery, heavy industry machinery, mining machinery, and metallurgical equipment, including speed reducers, crushers, metallurgical equipment, mining machinery, fans, water pumps, machine tools, hoisting equipment, agricultural machinery, engineering machinery, paper-making machinery, textile machinery, etc. Whether it is heavy-load equipment in mining and heavy industry or high-temperature working condition equipment in the metallurgical industry, the 22208CA/W33 spherical roller bearing can meet the transmission needs under various heavy-load, eccentric and impact working conditions with its excellent self-aligning ability and heavy-load bearing performance, especially suitable for heavy-load equipment scenarios that require high self-aligning performance and load-bearing capacity.

Usage Method: Before installation, thoroughly clean the inner ring, outer ring, rolling elements of the bearing, as well as the mounting surfaces of the bearing housing and shaft diameter to ensure there is no oil stain, rust, debris or burr, so as to avoid scratching the bearing surface and damaging the CA brass cage during installation, which will affect the operation precision and service life; during installation, keep the coaxiality of the bearing with the shaft and bearing housing, make full use of its self-aligning function to compensate for installation deviation, and adopt the press-fitting method or hot-fitting method (the hot-fitting temperature should not exceed 120℃). It is forbidden to knock the bearing forcefully to prevent deformation of the inner and outer rings of the bearing, damage to the rolling elements or deformation of the brass cage; after installation, check the rotational flexibility of the bearing to ensure there is no jamming, abnormal noise, looseness or other abnormal conditions, and adjust the bearing clearance to an appropriate range; during use, add special grease (or lubricating oil) regularly through the W33 oil groove to keep the interior of the bearing fully lubricated and avoid component wear and cage damage caused by dry friction; at the same time, avoid the bearing being in an environment of long-term overload, high temperature, humidity or heavy dust to prevent bearing rust and accelerated wear; regularly check the operation status of the bearing, and if problems such as bearing overheating, abnormal noise, precision degradation or cage damage are found, stop the machine for inspection in time and replace the bearing if necessary to ensure the normal operation of the equipment.

Service Life: The service life of 22208CA/W33 spherical roller bearing mainly depends on the working conditions, installation accuracy, lubrication and maintenance, as well as the load size. Under standard working conditions (normal temperature, rated load, medium-low speed operation, regular lubrication, clean environment), if installed standardizedly and maintained properly, the service life can reach 3-5 years; in a light-load, clean and constant-temperature environment (such as precision machine tools and light reducers), the service life can be extended to 5-7 years; if used in harsh working conditions such as heavy load, high speed, frequent impact, dust and humidity (such as mining machinery, engineering machinery and metallurgical equipment), the service life will be shortened to about 1.5-3 years. In addition, regular lubrication and maintenance, avoiding overload and severe impact, timely adjusting the bearing clearance, and protecting the brass cage from damage are the keys to extending the service life of the bearing, and reasonable maintenance can increase the service life of the bearing by more than 30%.
