FAG — Precision Rolling Bearings by Schaeffler

About FAG

FAG is a German rolling bearing brand from Schweinfurt, founded in 1883 when Friedrich Fischer invented a ball grinding machine that could mass-produce perfectly round steel balls, a development widely seen as the start of the modern rolling bearing industry. Part of the Schaeffler Group since 2001, FAG is one of the world's leading bearing brands for machine building, automotive, and aerospace applications, with bearings ranging from a few millimetres to several metres in diameter.

Niche / Flagship Products

X-life Premium Bearings

Schaeffler's high-performance quality grade for FAG bearings, offering higher dynamic load ratings, longer rating life, and more load capacity within the same design envelope.

FAG Spherical Roller Bearings (E1 / X-life)

Heavy-duty bearings for very high loads, shaft deflection, and misalignment, used in mining, paper, steel, and heavy machinery.

FAG Split Spherical Roller Bearings

Split-design bearings that fit into standard housings, so worn bearings can be replaced without dismantling the shaft or housing.

FAG Super Precision Bearings

High-precision spindle bearings and precision cylindrical roller bearings for machine tool spindles and high-speed applications.

TAROL Axlebox Bearings

Ready-to-fit tapered roller bearing units designed for railway axleboxes.

Current-Insulated & Hybrid Bearings

Bearings with ceramic-coated rings or ceramic rolling elements that protect electric motors and generators from damage caused by electrical current passing through the bearing.

Specialized Product Categories

Deep Groove Ball Bearings

FAG's most widely used bearing type, available open, shielded, or sealed for general industrial and automotive use.

Cylindrical Roller Bearings

Single-row, double-row, and full-complement designs for high radial loads and high speeds.

Tapered Roller Bearings

Metric and inch-series bearings for combined radial and axial loads in gearboxes, axles, and vehicles.

Spherical Roller Bearings

Self-aligning bearings for heavy loads in harsh operating conditions.

Axial Spherical Roller Bearings

Thrust bearings for very high axial loads, with low-friction roller end geometry.

Angular Contact Ball Bearings

Single-row, double-row, and four-point contact designs for combined loads and precise shaft guidance.

Bearing Housings & Plummer Blocks

Split and one-piece housings, including plummer block units, for mounting FAG bearings in industrial equipment.
