Description
.
As a manufacturer located in China, I would like to introduce my product TIMKEN Spherical Roller Bearings to merchants outside of China. These spherical roller bearings are high-quality bearings that have become widely popular due to their stable quality, long service life, and high load-bearing capacity. TIMKEN Spherical Roller Bearings are used in various industries such as mining, construction, and agricultural machinery. These bearings are known for their exceptional durability and reliability, even under extreme conditions.
Features and Benefits
TIMKEN Spherical Roller Bearings are designed with several unique features to provide a superior performance and long-lasting durability. The following are some of the most notable features and benefits of TIMKEN Spherical Roller Bearings:
1. High Load-Bearing Capacity
These bearings are designed to withstand heavy loads and provide a high load-bearing capacity. The rollers in these bearings are oriented at an angle to the bearing axis, which allows them to support a combination of radial and axial loads and absorb shock.
2. High-Quality Materials
TIMKEN Spherical Roller Bearings are made from high-quality materials such as steel and brass, which ensures excellent stability, precision, and durability. The bearing elements are heat-treated for maximum hardness, toughness, and durability.
3. Self-Aligning Capability
These bearings are designed to automatically align themselves with the shaft and housing. This feature allows them to compensate for any misalignment caused by installation errors or equipment deflection, resulting in reduced vibration and noise levels.
4. C3 Clearance
TIMKEN Spherical Roller Bearings with C3 clearance provide extra clearance between the internal components, which allows for an increase in machine vibrational and shock loads. The C3 internal clearance reduces heat generation and extends the bearing's lifespan.
Applications
TIMKEN Spherical Roller Bearings are used in a wide range of industries and machinery, including:
1. Mining Equipment
TIMKEN Spherical Roller Bearings are widely used in mining machinery, including conveyors, crushers, and vibrating screens. The bearings are designed to operate under harsh conditions and provide reliable performance, even in the most challenging mining environments.
2. Construction Machinery
These bearings are also used in various construction equipment, including excavators, bulldozers, and cranes. TIMKEN Spherical Roller Bearings are capable of withstanding heavy loads and shock loads, making them ideal for use in construction machinery.
3. Agricultural Machinery
TIMKEN Spherical Roller Bearings are used in a variety of agricultural machinery, such as tractors, harvesters, and sprayers. These bearings provide reliable performance in extremely dusty and dirty environments.
4. Papermaking Machinery
The bearings are also used in papermaking machinery, including rollers, tensioners, and feeders. TIMKEN Spherical Roller Bearings are designed to provide stable performance under high-speed and high-load conditions, allowing for smooth paper production.
Conclusion
In conclusion, TIMKEN Spherical Roller Bearings are high-quality bearings that provide superior performance, durability, and reliability. These bearings are widely used in various industries such as mining, construction, and agricultural machinery. The unique features of TIMKEN Spherical Roller Bearings ensure excellent stability, precision, and durability, making them an ideal choice for machinery manufacturers and equipment suppliers seeking reliable, high-performance bearings. I would be happy to provide more information or samples upon request to interested merchants outside of China.

● Production Details
◆ Turned bearing rings from forgings
Since the shape and size of the forging blank are close to the bearing ring, the processing is not limited by equipment and batches. It can be processed in a centralized process or can be processed in a decentralized way, so it is the most commonly used. In terms of technology, it is generally formed in two processes. The first process mainly completes the boring and the end face, and the second process mainly completes the outer circle and the other end face of the car. The machining of chamfers and grooves is arranged according to the functions of different lathes. The most common lathes used are semi-automatic lathes (up and down are performed manually).
◆ Metallographic microscope observation and microstructure evaluation
Standard image comparison methods are usually used. The microstructure evaluation items of bearing steel include carbide network, quenching and tempering structure, quenching and tempering troostite structure and soft spot.
1. The evaluation of reticulated carbide mainly considers the degree of closure of the reticular and the thickness of the mesh. Grades less than or equal to 2.5 are allowed, and grades greater than 3 are not allowed.
2. The quenched and tempered structure should be composed of hidden products, fine crystalline martensite, evenly distributed fine residual carbides, a small amount of retained austenite and a small amount of troostite. According to the thickness of martensite and the shape of troostite, it is divided into 5 grades, all of which are qualified microstructures.
3. The evaluation of the troostite structure is the bainite isothermal quenching structure, which is composed of bainite, residual carbide and a small amount of troostite. The JB/T1255-2001 standard divides the quenched and tempered troostite structure into Level 5, they are all qualified organizations.
● Cold Extrusion Process
Small bearing rings can adopt cold extrusion process, and there are several forming schemes. Considering the stability and reliability of the forming process, reducing the extrusion force, improving the life of the die, and organizing the production management, etc., at present, the composite cold extrusion forming process plan with an endless belt and sleeve material has been popularized and applied. The process plan is: Blanking → cold heading cake → annealing and softening structure → pickling, phosphating, rejuvenation → compound and extrusion → separating outer coil → separating annular belt → annealing and softening structure → pickling, phosphating, saponification → squeezing inner ring reversely → separating inner ring completely.
