Description

Basic Parameters

In the double row tapered roller bearing model 352122: “3” indicates the bearing type is a tapered roller bearing. Tapered roller bearings can withstand both large radial and axial loads simultaneously. Their rollers and raceways form a tapered contact, a unique structure that makes them excellent at handling combined loads.

 

“5” represents the width series code, which reflects the size range in the width direction. The 5 series typically means the bearing has a moderate width, adapting to specific installation spaces and load distribution needs.

 

“21” is the diameter series code. Combined with specific size rules, this series corresponds to a particular range of inner and outer diameters. In 352122, it works with other parameters to determine the overall radial dimensions of the bearing.

 

“22” is the inner diameter code. Following the calculation rule (inner diameter = code × 5), the inner diameter of this bearing is 22 × 5 = 110mm. The tolerance grade is not directly marked in the 352122 model and defaults to the normal grade (PN). This grade meets the requirements for dimensional and rotational accuracy in most conventional mechanical applications.

 

In summary, 352122 refers to a double row tapered roller bearing with moderate width, a specific diameter series, 110mm inner diameter, and normal precision. It is widely used in heavy machinery and industrial transmission devices, playing a key role in working conditions requiring large combined radial and axial loads.

 

 

 

 

 

Product Application

The 352122 double row tapered roller bearings are widely used in heavy-duty machinery, industrial gearboxes, construction equipment, mining machinery, metallurgical rolling mills, railway locomotives, large-scale conveyors, marine transmissions, wind power gearboxes, crane systems, paper making machinery, petroleum drilling equipment, cement production lines, port handling machinery, agricultural tractors, truck differentials, steel processing equipment, printing presses, plastic extrusion machines, industrial pumps, gear reducers, conveyor belts, metallurgical machinery, forestry equipment, marine engines, railway carriages, construction machinery, mining conveyors, power transmission systems, and material handling equipment, among other fields.
Designed to handle high radial and axial loads simultaneously, these bearings excel in applications requiring robust load-bearing capacity and precision. In heavy machinery such as mining crushers and construction excavators, they ensure stable operation under extreme loads. Industrial gearboxes rely on them for efficient power transmission, while railway locomotives use them to support axle loads and maintain smooth motion. Marine transmissions benefit from their durability in harsh environments, and wind power gearboxes leverage their reliability for renewable energy applications.
In agricultural tractors and truck differentials, they enhance torque transfer and withstand vibrations, while in steel processing and cement production, they endure high-temperature and dusty conditions. Their double-row structure provides enhanced rigidity, making them ideal for precision-critical setups like printing presses and plastic extrusion machines. From heavy industrial installations to specialized mechanical systems, the 352122 bearings offer consistent performance, ensuring long service life and minimal maintenance in demanding operational environments.
