FAG Bearing Designation Decoding, Suffix Identification & X-life Standard

Founded in 1883 in Schweinfurt, Germany by Friedrich Fischer and integrated into the Schaeffler Group in 2001, FAG manufactures industrial rolling and plain bearings ranging from 3 mm bore diameter up to 4.25 meters outside diameter for machine tools, metallurgy, mining, cement, pulp and paper, and

wind energy.

To ensure accurate bearing or housing unit identification, specify the complete alphanumeric designation stamped on the bearing ring face or packaging label: for example, HSS 71902-C-T-P4S-UL, B7014-C-T-P4S-UL, 22322-E1-XL-K-C3, 23936-S-MB, NU2230-E-XL-M1, QJ230-N2-MPA, 32230-A-XL, or 6314-2Z-C3.

FAG suffixes define critical operating parameters: XL denotes the X-life extended service life standard, C3 and C4 indicate expanded radial internal clearance, K and K30 specify 1:12 and 1:30 tapered bores, MB and M1 denote solid brass cages, TVP2 indicates a glass-fiber reinforced polyamide cage,

and P4S and SP define super-precision spindle tolerances.

CNC Machine Tool Spindle Overhaul with FAG P4S Super-Precision Bearings

When overhauling motorized electro-spindles and CNC turning or milling heads, selecting the exact contact angle (15° code C or 25° code E), rolling element material (100Cr6 steel or Si3N4 ceramic balls in hybrid HC / HCM series), and preload class (L light, M medium, H heavy) is essential.

High-speed sealed spindle bearings of series HSS70 and HSS719 are factory-greased for life and fitted with non-contact gap seals on both sides, preventing coolant vapor and fine particle ingress at rotational speeds exceeding 20000 rpm.

We supply universally matched single bearings (UL, UM, UH) and factory-calibrated matched sets (duplex, triplex, quadruplex) with sorted bore and outside diameter tolerances, along with ZKLN, ZKLF, and BSB ball screw support bearings.

Heavy-Duty FAG X-life Spherical and Cylindrical Roller Bearings

Crushers, vibrating screens, ball mills, steel converters, and main conveyor gearboxes rely on FAG double-row spherical roller bearings of series 222, 223, 230, 231, 232, 239, 240, and 241 in E1-XL execution.

Eliminating the fixed central inner ring rib allows longer rollers and a floating guide ring, minimizing friction and operating temperature.

For vibrating screens and exciters, FAG produces specialized T41A and T41D spherical roller bearings featuring restricted bore and outer diameter tolerances, C4 radial internal clearance, and outer-ring-guided solid brass cages (MA).

Floating and locating positions in high-power electric motors and gear drives utilize FAG cylindrical roller bearings of series NU, NJ, NUP, full-complement series NCF / NJG, and self-aligning FAG TORB toroidal roller bearings.

Current-Insulated FAG Insutect Bearings for VFD-Driven Electric Motors

Operating AC induction and synchronous motors on variable frequency drives generates parasitic high-frequency shaft voltages. Electrical discharge across the thin lubricant film causes electrical erosion and raceway fluting, rapidly degrading grease and bearing surfaces.

To protect drive trains, FAG manufactures current-insulated ball and cylindrical roller bearings coated with plasma-sprayed aluminum oxide ceramic Insutect layers on the outer or inner ring (suffixes J20AA, J20AB, J20B providing minimum 50 MOhm insulation resistance at 1000–3000 V DC), as well as

hybrid ceramic-ball bearings.

We supply FAG Insutect bearings across series 62, 63, NU2, and NU3 for traction motors, wind turbine generators, compressor stations, and industrial pump drives.

Split Plummer Block Housings SNS / SNV, Split Bearings & Sleeve Mounting

FAG SNS split plummer block housings extend the service life of installed spherical roller bearings by up to 50% compared to conventional housings due to optimized housing base rigidity and uniform load distribution across the lower support zone.

For maintenance on hard-to-access trapped transmission shafts in industrial fans, bucket elevators, and mine hoists, FAG 222..K-MB-SPLIT split spherical roller bearings feature halved inner rings, outer rings, and roller cage assemblies, enabling bearing replacement without dismantling couplings or

gearboxes.

We supply complete SNS, SNV, SNG, and SAF housing assemblies equipped with double-lip (DH), labyrinth (TS), felt (FS), or heavy-duty Taconite seals, locating rings (FR), adapter sleeves (H), and withdrawal sleeves (AH).

FAG Arcanol Bearing Greases, HEATER Induction Mounting & OPTIME Condition Monitoring

Up to 80% of premature rolling bearing failures stem from improper lubrication, contamination, or mounting damage.

FAG Arcanol rolling bearing greases are FE8 and FE9 rig-tested across universal (MULTITOP, MULTI2, MULTI3), high-temperature (TEMP90, TEMP110, TEMP120, TEMP200), heavy-load (LOAD150, LOAD220, LOAD400, LOAD460), high-speed spindle (SPEED2,6), vibration (VIB3), and NSF H1 food-grade (FOOD2) grades.

Automated single-point and multi-point lubrication is handled by FAG CONCEPT1, CONCEPT2, and CONCEPT8 lubricators. Safe damage-free interference mounting is achieved using FAG HEATER induction heating devices (models 10–35 up to heavy units 150–1200) and HYDNUT hydraulic nuts.

For continuous predictive maintenance, we supply wireless Schaeffler OPTIME vibration and temperature sensors and single-channel FAG SmartCheck condition monitoring systems.
