What is the role of the bearing?
A bearing is a mechanical element that restricts relative motion within the required range of motion and reduces friction between moving parts. The design of the bearing can provide free linear movement of the moving parts or free rotation around a fixed axis, and can also prevent movement by controlling the vector of the normal force acting on the moving parts. Most bearings promote the required movement by minimizing friction. Bearings can be broadly classified according to different methods such as the type of operation, the allowed movement, or the direction of the load (force) applied to the part. Spark Company can provide cylindrical roller bearings.
Rotating bearings support rotating parts such as rods or shafts in the mechanical system, and transfer axial and radial loads from the load source to the structure that supports it. The simplest bearing is a sliding bearing, which consists of a shaft that rotates in a hole. Reduce friction through lubrication. In ball bearings and roller bearings, in order to reduce sliding friction, rolling elements with round cross-section rollers or balls are placed between the races or journals of the bearing assembly. A variety of bearing designs can correctly meet different application requirements to maximize efficiency, improve reliability and durability. Spark Company can provide cylindrical roller bearings.
Basic performance of spherical roller bearings
Wear resistance
When the bearing (spherical roller bearing) is working, not only rolling friction occurs between the ring, rolling element and the cage, but also sliding friction occurs, so that the bearing parts are constantly worn. In order to reduce the wear of bearing parts, maintain the stability of bearing accuracy and prolong the service life, the bearing steel should have good wear resistance.
Contact fatigue strength
Under the action of cyclic load, the contact surface is prone to fatigue damage, that is, cracking and peeling, which is the main damage form of the bearing. Therefore, in order to improve the service life of the bearing, the bearing steel must have a high contact fatigue strength.
Hardness
Hardness is one of the important qualities of bearing quality, and it has a direct impact on contact fatigue strength, wear resistance, and elastic limit. The hardness of the bearing steel in use should generally reach HRC61~65, so that the bearing can obtain higher contact fatigue strength and wear resistance.
Anti-rust performance
In order to prevent bearing parts and finished products from being corroded and rusted during processing, storage and use, the bearing steel is required to have good rust resistance.
Processing performance
In the production process of bearing parts, there are many cold and hot processing procedures. In order to meet the requirements of large-scale, high-efficiency and high-quality, bearing steel should have good processing performance. For example, cold and hot forming performance, cutting performance, hardenability and so on.
