Spherical Roller Bearing: Engineering for Heavy Loads and Misalignment 

شار شەكىللىك غالتەكلىكs are the workhorses of the bearing world, designed to thrive in applications where heavy loads, high speeds, and misalignment are common. Unlike other bearing types, they feature two rows of barrel-shaped rollers that run on a spherical outer ring raceway, allowing them to accommodate shaft deflections and misalignment up to 3 degrees. This unique design makes spherical roller bearings indispensable in industries such as mining, construction, and manufacturing, where machinery operates under less-than-ideal conditions. At Botong, crafting high-quality spherical roller bearings is a blend of art and science, ensuring that each component delivers exceptional performance and longevity.​

Botong’s spherical roller bearings, such as their PLC 110-190 model designed for mixer reducers, exemplify their engineering expertise. Let’s examine the key features of this bearing and how they address industrial challenges:​

​

​

The PLC 110-190 spherical roller bearing is a prime example of Botong’s customer-centric approach. By designing a bearing specifically for mixer reducers, they address the unique challenges of this application: mixer reducers operate under heavy loads, experience frequent start-stop cycles, and are prone to misalignment due to vibration. The spherical design of the PLC 110-190 bearing mitigates these issues, reducing stress on the machinery and ensuring smooth operation.​

Botong’s spherical roller bearings are crafted from high-grade materials, chosen for their strength, wear resistance, and ability to withstand high temperatures. The manufacturing process involves precision grinding of raceways and rollers to ensure tight tolerances, while heat treatment enhances the material’s hardness and durability. Each bearing undergoes rigorous testing, including load testing and dimensional checks, to ensure it meets Botong’s strict quality standards. For industries that rely on heavy machinery, Botong’s spherical roller bearings are more than components—they are critical to maintaining productivity, reducing downtime, and extending equipment lifespan.​

Axial Spherical Roller Bearing: Mastering Axial Loads with Precision 

While spherical roller bearings excel at handling combined radial and axial loads, the axial spherical roller bearing is specifically engineered to manage heavy axial (thrust) loads—forces that act parallel to the shaft. In industrial applications such as press machines, gearboxes, and crane hooks, axial loads can be immense, requiring bearings that offer both strength and precision. Botong’s axial spherical roller bearings are designed to meet these demands, providing reliable performance in even the most challenging environments.​

The axial spherical roller bearing features a unique design that includes two rows of symmetrical spherical rollers, a central guide ring, and raceways that are spherical in shape. This configuration allows the bearing to accommodate axial loads in both directions, as well as moderate radial loads and misalignment. For industries where axial movement is unavoidable—such as in hydraulic presses or vertical turbines—this versatility is invaluable, preventing premature wear and ensuring smooth, controlled motion.​

Botong’s axial spherical roller bearings are crafted with the same attention to detail as their radial counterparts. The choice of materials is critical: high-carbon chromium steel is commonly used for its excellent wear resistance and fatigue strength, while advanced heat treatment processes enhance the bearing’s ability to withstand heavy loads. The rollers and raceways are precision ground to ensure uniform contact, distributing loads evenly and minimizing stress points. This meticulous manufacturing ensures that Botong’s axial spherical roller bearings can handle axial loads ranging from thousands to hundreds of thousands of newtons, making them suitable for a wide range of industrial applications.​

One of the key advantages of Botong’s axial spherical roller bearings is their ability to operate in harsh conditions. Whether exposed to dust, moisture, or high temperatures, these bearings maintain their performance thanks to features such as sealed designs and high-temperature lubricants. In industries like steel manufacturing, where equipment operates at extreme temperatures, or in mining, where dust and debris are prevalent, Botong’s bearings provide the reliability needed to keep operations running smoothly.​

Botong’s engineering team works closely with clients to customize axial spherical roller bearings for specific applications. By analyzing factors such as load magnitude, operating temperature, and speed, they can recommend modifications to bearing design, material, or lubrication, ensuring optimal performance. This tailored approach has made Botong a trusted partner for industries seeking bearings that can handle the unique challenges of axial motion.​

Spherical Roller Thrust Bearing: Powering Heavy-Duty Thrust Applications

​

In applications where axial loads are extreme, the spherical roller thrust bearing takes center stage. This specialized bearing is designed to handle heavy thrust loads while accommodating misalignment, making it essential in machinery such as marine propellers, hydroelectric turbines, and large gearboxes. Botong’s spherical roller thrust bearings build on their expertise in spherical roller technology, offering the strength and durability needed to power some of the world’s most demanding industrial applications.​

The spherical roller thrust bearing differs from the axial spherical roller bearing in its design focus: while both handle axial loads, the thrust bearing is optimized for very high thrust loads with limited radial load capacity. It features a series of asymmetrical spherical rollers arranged between a shaft washer and a housing washer, with a spherical raceway on the housing washer that allows for misalignment. This design ensures that even under heavy thrust loads, the bearing maintains uniform roller contact, reducing stress and extending service life.​

Botong’s spherical roller thrust bearings are manufactured using high-strength materials, including alloy steels and heat-resistant alloys, to withstand the extreme pressures of heavy thrust applications. The manufacturing process involves precision machining of washers and rollers, with strict quality control to ensure dimensional accuracy. Each bearing is tested under simulated operating conditions to verify its load capacity, wear resistance, and ability to accommodate misalignment.​

One of the key benefits of Botong’s spherical roller thrust bearings is their long service life, even in harsh environments. By minimizing friction through optimized roller design and high-quality lubrication, these bearings reduce heat generation and wear, lowering maintenance requirements and downtime. In industries where equipment failure can result in significant costs—such as in power generation or marine propulsion—this reliability is invaluable.​

Botong’s spherical roller thrust bearings are also designed for ease of installation and maintenance. Features such as separable washers allow for simple mounting and dismounting, while grease fittings enable easy lubrication replenishment. This user-friendly design ensures that maintenance teams can quickly service the bearings, reducing downtime and keeping machinery operational.​

Whether powering a hydroelectric turbine or a large industrial mixer, Botong’s spherical roller thrust bearings play a critical role in enabling safe, efficient motion. By combining advanced engineering with high-quality materials, Botong has established itself as a provider of bearings that can handle the heaviest thrust loads with confidence.​
