Support and guide rotating or oscillating machine elements, and transmit loads between machine parts.
Bearings, also known as axis bearings, derive their name from the English word "Bearing." The term "Bear" means to endure or to bear a load, and the Japanese term for axis bearings signifies that they bear the load of the axis. Bearings are mechanical components that support and guide rotating or oscillating machine elements (such as shafts, axles, and wheels) and transmit loads between machine components. There are sliding bearings that directly support the axis and rolling bearings that support the axis through rolling elements like balls or rollers. Machines with rotating parts always use bearings, which function to reduce friction between the axis and surrounding components and suppress heat generation, making the bearings themselves sustainable products. Rolling bearings enable high-speed rotation due to their high precision and low friction while also reducing operating noise, heat generation, energy consumption, and wear. Rolling bearings are cost-effective, replaceable machine elements that typically conform to domestic or international dimensional standards (such as JIS or ISO). *For more details, please refer to the catalog or feel free to contact us.*

Detailed information
-
Hybrid Bearings Hybrid bearings consist of a raceway made of bearing steel and rolling elements made of silicon nitride (Si3N4). SKF hybrid bearings are designed with dimensions that are interchangeable with all-steel bearings of the same size. Incorporating them into new and existing industrial equipment significantly enhances reliability and robustness.
-
High-Temperature Bearings SKF high-temperature bearings continuously lubricate the bearings with a graphite-based lubricant, eliminating the need for grease or lubricating oil. Designed for applications in the steel industry and food and beverage industry, these bearings are engineered to operate trouble-free in high-temperature environments of up to 350 °C.
-
Solid Oil Bearings Solid oil is a resin material that is saturated with oil, effectively filling the entire space volume of the bearing. SKF solid oil bearings are designed for use in applications where high humidity environments or accidental contact with water and contaminants could pose significant problems. These bearings are an excellent choice for applications where re-lubrication is impractical or poses risks.
-
INSOCOAT insulated bearings SKF's INSCOAT insulated bearings are designed to protect bearings from current passing through them. By integrating insulation properties into the bearings, INSCOAT virtually eliminates issues caused by electrical corrosion in the applications listed below, enhancing equipment reliability and extending uptime.

NoWear Coated Bearings Smearing can become a problem in low-load paper-making applications or in applications where load and speed change rapidly. When rolling elements slip, an oil film is not formed, leading to severe wear due to metal-to-metal contact. As a result, unplanned downtime occurs, resulting in unnecessarily high replacement and maintenance costs associated with the purchase and installation of new bearings. To overcome such issues, SKF has developed NoWear bearings. NoWear components are coated with a ceramic material that has low friction and high hardness characteristics, and extremely low affinity for bonding with other material surfaces. This coating has been proven to be very effective in preventing early damage to bearings due to smearing under low-load and high-speed operating conditions. Additionally, due to these coating properties, NoWear bearings are also effective in preventing excessive wear caused by vibration-related failures and poor lubrication (such as boundary lubrication conditions, insufficient lubricants, emergency lubrication oil depletion, or "dry running" situations).

Motor Encoder Unit When continuously monitoring the rotational speed and direction of an AC induction motor, an encoder is required. Conventional encoders are typically mounted externally on the motor, which often exposes them to environmental conditions that can significantly affect their practical lifespan. However, the SKF motor encoder unit integrates the functions of the encoder and bearing. This unit can be installed at either bearing position of the AC induction motor and is only 6.2 mm wider compared to the corresponding standard deep groove ball bearing.
