The 7413-B-XL-MP-UA C3 FAG is a heavy-duty single-row 40° angular contact ball bearing from FAG XL optimized series with MP machined brass cage, UA universal pairing clearance and enlarged C3 internal clearance, designed to withstand substantial combined radial and bidirectional axial loads for heavy-load high-speed precision rotating assemblies.
In compliance with ISO 355 specification, standard dimensional data: bore 65 mm, outer diameter 160 mm, width 37 mm, chamfer 2.0×45°, dimensional tolerance P0 grade, C3 enlarged radial clearance for thermal expansion compensation. UA design allows arbitrary duplex pairing to preset required preload without spacer adjustment.
Inner/outer rings and rolling balls adopt vacuum degassed 100Cr6 chrome bearing steel, quenched hardness HRC 61–63 with outstanding contact fatigue resistance, abrasion resistance and dimensional stability under fluctuating load. MP solid machined brass cage delivers superior high-temperature stability, structural rigidity and reliable ball separation under continuous heavy-duty operation.
Core production procedures cover precision die forging, CNC precision turning, controlled-atmosphere quenching & low-temperature tempering, raceway precision grinding and superfinishing. Optimized forging improves internal metal fiber continuity; regulated heat treatment eliminates residual stress; ultra-precision superfinishing lowers surface roughness to cut running friction and vibration.
Calculated per ISO 281 bearing life standard, the rated L10 service life reaches 71000 working hours under standard rated load, stable rotating speed and qualified lubrication. Practical service life varies by actual load ratio, operating temperature, mounting alignment, lubricant quality and pairing preload setting.
This FAG bearing is widely deployed in heavy-duty industrial gearboxes, metallurgical equipment, large-size industrial compressors, mining machinery and high-power fan spindles. 40° large contact angle offers prominent axial load capacity; C3 clearance adapts high-temperature running; UA interchangeable pairing meets diversified preload demands of precision heavy machinery.
Perform relubrication every 320 working hours with high-temperature EP lithium grease, single filling volume 2.2–2.8 g. Keep bearing assembly free from dust and corrosive pollutants; periodically check operating temperature, abnormal noise and preload variation, replace defective components upon persistent abnormal wear.
Clean matching shaft and housing to confirm H7/h6 fitting tolerance before installation; adopt symmetric press fitting and forbid hammer striking; control shaft concentricity within 0.02 mm/m and apply specified tightening torque. Complete no-load running test post-installation; wear protective gloves during assembly for safety protection.
