High-temperature Short Cylindrical Roller Bearings

Introduction to high-temperature short cylindrical roller bearings:

High-temperature short cylindrical roller bearings are bearings that can operate in high-temperature environments and are mainly used to withstand radial loads and some axial loads. These bearings are usually made of high-temperature resistant materials and can operate stably at high temperatures of 500-800°C. They have characteristics such as oxidation resistance, corrosion resistance, high hardness, wear resistance, strong impact resistance, and excellent anti-seizure ability.

The main characteristics of high-temperature short cylindrical roller bearings include:

Excellent High-temperature Resistance: High-temperature short-cylindrical roller bearings can maintain good lubrication performance and load-bearing capacity in high-temperature environments. Some specially designed high-temperature bearings can withstand high temperatures of thousands of degrees Celsius. This is mainly due to the use of heat-resistant alloys such as tungsten and rhenium to manufacture rolling elements and cages. These alloys can still maintain good mechanical properties at high temperatures.

Low Friction Coefficient: Under high-temperature working conditions, the viscosity of the lubricating oil will decrease due to the increase in temperature, and its fluidity will increase, making it easy to slide off high-speed rotating components, resulting in lubrication failure. 

The main application scenarios of high-temperature short-cylindrical roller bearings include the following:

Metallurgical Industry: In the process of steel production and non-ferrous metal smelting, high-temperature short-cylindrical roller bearings are widely used in equipment such as high-temperature furnace charge conveyors, high - temperature steam turbines, high-temperature furnaces, high-temperature heat-treatment equipment, and high-temperature conveyors to ensure stable operation in high-temperature environments.Petrochemical Industry: In petrochemical production, high-temperature short-cylindrical roller bearings are used in equipment such as steam turbines, high-temperature pumps, and high-temperature compressors. These equipment need to operate in high-temperature, high-pressure, and corrosive environments.Aerospace Field: High-temperature short-cylindrical roller bearings are widely used in key equipment such as high-temperature turbines and high-temperature aero-engines, withstanding high-temperature and high-speed operating environments.Power Industry: In power equipment, such as generators and gas turbines, high-temperature short-cylindrical roller bearings can ensure the stable operation of the equipment in high-temperature environments.Industrial Manufacturing: In the industrial manufacturing field, in equipment such as rolling mills and vibrating screens, high-temperature short-cylindrical roller bearings can withstand high - temperature and heavy-load working conditions.Rail Transit: In transportation vehicles such as locomotives, vehicles, and internal combustion engines, high - temperature short-cylindrical roller bearings can provide stable support and durability.Shipbuilding: In the mechanical equipment of ships, such as reduction gearboxes and lifting and transportation machinery, high-temperature short-cylindrical roller bearings can ensure reliable operation in complex marine environments.Wind Power Industry: In the transmission system of wind power equipment, high-temperature short-cylindrical roller bearings can adapt to high-temperature and variable-load working environments, ensuring the stable operation of the equipment.
