Description

Basic Parameters

The basic parameters of the spherical roller bearing 22205 MB are as follows: the inner diameter is 25 mm, the outer diameter is 52 mm, and the width is 18 mm, with a cylindrical bore design. The basic dynamic load rating is approximately 43.1 kN, and the basic static load rating is approximately 50.6 kN. The reference speed for grease lubrication is 9200 rpm, and for oil lubrication, it is 11500 rpm. This bearing weighs about 0.2 kg and is equipped with a steel cage. The outer ring is provided with a lubrication groove and three lubrication holes, which improve lubrication efficiency and heat dissipation capacity, thereby enhancing performance and service life.

 

Product Application

Product Applications: The 22205 MB spherical roller bearing is specifically designed for a variety of industrial and mechanical applications that require high radial load-carrying capacity, moderate axial load-carrying capacity, and self-aligning performance. Its robust structure and special characteristics make it an ideal choice for working conditions involving misalignment, vibration, or heavy loads.

1. Industrial Machinery and Equipment
In industrial machinery such as gearboxes, conveyors, and pumps, this bearing can excellently withstand the large radial loads generated by rotating shafts or moving components. The cylindrical bore (25 mm) ensures it can be easily mounted on standard shafts, while the outer ring with a lubrication groove and three holes allows for efficient replenishment of grease or lubricating oil, thereby reducing maintenance downtime in continuously operating systems. The self-aligning design can compensate for slight shaft misalignment caused by installation errors or thermal expansion, preventing premature wear and extending the service life of components.
2. Automotive and Transportation
In automotive applications, the 22205 MB is suitable for wheel hubs, gearboxes, and suspension systems. It can withstand combined radial loads (such as those from vehicle weight and road irregularities) as well as moderate axial forces generated during cornering or braking, thereby ensuring stable performance. The steel cage and high-quality bearing steel structure can resist impact loads and vibrations, which is crucial for maintaining safety and reliability under harsh road conditions. The reference speeds (9,200 rpm for grease lubrication and 11,500 rpm for oil lubrication) are suitable for medium to high-speed rotation, making it applicable to both passenger cars and commercial trucks.
3. Agricultural and Construction Equipment
Agricultural machinery such as tractors, combine harvesters, and harvesters operates in dusty, humid, and highly vibrational environments, where bearings must withstand heavy loads and contaminated conditions. The lubrication groove and holes of the 22205MB bearing facilitate the uniform distribution of grease, preventing particle ingress and reducing friction even when exposed to dust or moisture. In construction equipment like excavators or loaders, this bearing supports pivot joints and boom mechanisms, effectively handling radial loads generated by repetitive movements and uneven terrain. With a weight of only 0.2 kg, it combines strength with a lightweight design, minimizing energy consumption in mobile machinery.
4. Heavy-Duty Industrial Tools
For applications such as machine tools, presses, or industrial fans, this bearing, with a basic dynamic load rating of 43.1 kN and a basic static load rating of 50.6 kN, is suitable for both intermittent and continuous heavy loads. The self-aligning feature is particularly beneficial for tools where precise shaft alignment is difficult, such as old machines or systems with flexible supports. The lubrication design enhances the bearing’s heat dissipation capacity, preventing overheating during high-speed operation, ensuring stable performance, and reducing the risk of thermal fatigue.
5. Material Handling and Conveying Systems
In conveyor belts used in mining, logistics, or manufacturing industries, the 22205 MB bearing can support idlers and drive rollers, effectively managing the radial loads generated by the transportation of heavy materials. The bearing has misalignment resistance, ensuring the smooth operation of the conveyor belt even when the conveyor frame slightly deflects under load. The durable steel cage and corrosion-resistant surface treatment (if applied, though not specified in the basic parameters) make it suitable for dusty or humid environments, thereby minimizing maintenance requirements for material handling systems in long-term operation.

 

Overall, the 22205MB achieves a balance in load capacity, self-aligning functionality, and lubrication efficiency, making it a reliable choice for various mechanical systems that demand high performance, durability, and the ability to adapt to harsh working conditions. Its design balances operational stability and ease of maintenance, making it a cost-effective solution in the fields of industry, automotive, and heavy-duty equipment.
