FAG BEARINGS

FAG Bearings, a brand with origins tracing back to 1883 in Schweinfurt, Germany, is a manufacturer of rolling bearings for industrial applications. The product line includes angular contact ball bearings, cylindrical roller bearings, self-aligning ball bearings, and other precision bearing types. FAG bearings are used in rotating equipment where load capacity, speed rating, and dimensional accuracy are specified. The brand is known for its metric-system bearings, with common precision grades including ABEC 3 and ABEC 5, and cage materials such as steel and polyamide (TVH). Seal and shield options include open, double-sealed (2RS), and double-shielded (2Z) configurations. Contact angles for angular contact bearings are typically 30° or 40°, and duplex mounting arrangements (tandem, back-to-back, face-to-face) are available for matched bearing sets. Cylindrical roller bearings in the NU design accommodate axial displacement and are often supplied with C3 internal clearance for applications with thermal expansion. 3G Electric stocks a range of FAG bearings, including double-row angular contact series (e.g., 3306, 3207) and single-row high-precision matched bearings (e.g., 7210, 7317). The inventory covers bore sizes from 17 mm to 85 mm and outer diameters up to 180 mm. 3G Electric provides logistics support for global shipment, enabling procurement specialists and plant engineers to source FAG bearings for maintenance, repair, and operations (MRO) or new equipment builds. The catalog includes both single bearings and matched duplex sets, with options for open or sealed variants. Technical specifications such as bearing industry numbers, manufacturer part numbers, and system of measurement are listed for each SKU to facilitate cross-referencing with existing equipment. FAG bearings are applied in electric motors, pumps, gearboxes, compressors, and machine tool spindles, where precise radial and axial load handling is required. The brand's long history in bearing manufacturing means its products are widely specified in industrial machinery globally. 3G Electric's offering supports engineers who need to replace or specify bearings with known performance characteristics, without reliance on marketing claims.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang FAG BEARINGS dari 3G Electric.

What precision grades are available for FAG angular contact ball bearings at 3G Electric?

FAG angular contact ball bearings stocked by 3G Electric are available in ABEC 3 and ABEC 5 precision grades. ABEC 3 is suitable for general industrial applications where moderate speed and load accuracy are required. ABEC 5 offers tighter dimensional and running tolerances, making it appropriate for higher-speed spindles or applications requiring reduced vibration. The specific grade is indicated in the product specifications for each SKU.

What is the difference between FAG double-row angular contact bearings and single-row matched duplex sets?

FAG double-row angular contact bearings (e.g., 3306/5306) integrate two rows of balls in a single unit, providing higher radial load capacity and axial load capacity in both directions. They are typically used in applications like pumps and gearboxes. Single-row matched duplex sets (e.g., 7210-B-XL-TVP-UA) consist of two bearings mounted together in a tandem, back-to-back, or face-to-face arrangement to handle combined loads or specific stiffness requirements. Duplex sets allow customization of preload and clearance for precision spindles.

What seal and shield options are available for FAG bearings from 3G Electric?

FAG bearings in the 3G Electric catalog are offered in open, double-sealed (2RS), and double-shielded (2Z) configurations. Open bearings have no seals or shields and are used in applications with external lubrication systems. Double-sealed bearings (2RS) have contact seals on both sides to retain grease and exclude contaminants. Double-shielded bearings (2Z) have non-contact shields that provide protection without increasing friction. The choice depends on operating environment and maintenance access.

How do I identify the correct FAG bearing for replacement using the bearing industry number?

Each FAG bearing in the 3G Electric catalog is listed with a bearing industry number (e.g., 3306/5306, 7210, 207) and a manufacturer part number (MPN). The industry number corresponds to standardized dimensions per ISO or DIN standards. For example, a 3306 bearing has a 30 mm bore, 72 mm OD, and 27 mm width. Cross-reference the industry number with your existing bearing's markings or equipment manual. The MPN provides additional details like cage material (TVP, M1) and internal clearance (C3).

What is the significance of the C3 internal clearance in FAG cylindrical roller bearings?

C3 internal clearance indicates that the bearing has greater radial internal clearance than normal (CN). This is specified for applications where thermal expansion of the shaft or housing may reduce clearance, such as in motors or compressors operating at elevated temperatures. FAG cylindrical roller bearings like the NU207-E-XL-M1-C3 are designed with C3 clearance to accommodate axial displacement and prevent preloading under thermal growth. It is not a precision grade but a clearance class.

Does 3G Electric supply FAG BEARINGS products?
