NB
Frequently asked questions
Common questions about NB from 3G Electric.
What is the construction of NB Alulin Series guide rails?
NB Alulin Series guide rails are constructed with a steel-reinforced aluminum profile. This design combines the rigidity of steel with the corrosion resistance and lightweight properties of aluminum. The rails are available in various nominal sizes, such as size 20, which has an overall width of 20 mm and height of 21.8 mm. They are suitable for applications requiring precise linear guidance with reduced weight. The steel reinforcement enhances load capacity and stiffness, making them appropriate for demanding industrial environments. The aluminum surface provides resistance to corrosion, extending service life in humid or chemically exposed settings. These guide rails can be used in automation, packaging, and material handling systems.
What are the available sizes for NB SWF-type round-flanged linear ball bearings?
NB SWF-type round-flanged linear ball bearings are available in multiple inner diameter sizes, including 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch, 1 inch, 1 1/4 inch, and 1 1/2 inches. Each size has a corresponding flange diameter, such as 1.25 inches for the 1/4-inch bore and 3.75 inches for the 1 1/2-inch bore. These bearings feature a resin body, which reduces weight and provides corrosion resistance. They are designed for light-duty linear motion applications where smooth operation and quietness are important. The single-flange design allows for mounting in various orientations. These bearings are commonly used in automation equipment, medical devices, and semiconductor handling systems.
What materials are used in NB linear ball bearings?
NB linear ball bearings, such as the SWF series, utilize a resin body. This material choice reduces the overall weight of the bearing and provides resistance to corrosion. The resin construction also contributes to quieter operation compared to all-metal bearings. The internal rolling elements are typically steel balls, which ensure smooth linear motion and load carrying capacity. The combination of resin and steel allows for use in environments where moisture or chemicals might be present, although specific chemical compatibility should be verified. These bearings are suitable for light-duty applications and are often found in automation, packaging, and medical equipment. For high-load or high-temperature applications, alternative materials may be required.

What are the typical applications for NB Alulin Series guide rails?
NB Alulin Series guide rails are used in applications that require precise linear motion with moderate load capacity. Common industries include semiconductor manufacturing, where cleanliness and corrosion resistance are important; automation systems, for pick-and-place and positioning tasks; packaging machinery, for guiding cutting or sealing heads; and material handling equipment, such as conveyor diverters. The steel-reinforced aluminum construction provides a balance of rigidity and weight, making these rails suitable for both static and dynamic loads. They can be integrated with various carriage types to suit specific motion requirements. The availability of lengths up to 4,000 mm allows for long travel distances. These guide rails are often chosen for their durability and smooth operation in continuous duty cycles.
Are NB linear ball bearings suitable for high-temperature environments?
NB linear ball bearings with resin bodies, such as the SWF series, are generally intended for operating temperatures within the limits of the resin material. Typical resin bearings have a maximum continuous operating temperature that may be lower than all-metal bearings. For high-temperature applications, it is advisable to consult the manufacturer's specifications or consider alternative bearing types. The resin material offers benefits such as corrosion resistance and weight reduction, but may not be suitable for extreme heat. In environments where temperature exceeds the resin's rating, steel or ceramic bearings might be more appropriate. Always verify the temperature limits for the specific bearing model before use in such conditions.
