1.Product Overview
T7FC080-XL and T7FC080/QCL7C belong to ISO355 standard T7FC series single row separable tapered roller bearing, unified core dimension inner bore d=80mm, outer diameter D=160mm, total assembly width T=45mm, inner ring width B=41mm, outer ring width C=31mm, built-in 30° large contact angle design for strong axial bearing capacity迈埃肯(上....
Suffix technical differentiation explanation:

• XL: X-life premium upgraded version, ultra-precision mirror superfinished raceway, strictly classified uniform tapered rollers, optimized internal contact geometry and dedicated stress relief heat treatment, 70% longer service life than standard models, specially matched for 24-hour non-stop continuous heavy-duty production linesschaeffler...;
• QCL7C: Explorer high-performance grade, Q optimized logarithmic contact curve + CL7C special surface strengthening treatment, ultra-low friction torque, stable low-temperature rise and low-noise rotation, stronger anti-vibration performance under alternating shock load, ideal for high-precision heavy transmission gearboxes.

Full separable split construction: the integrated assembly of inner ring, tapered rollers and cage can be fully detached from outer ring, greatly simplifying shaft installation, disassembly and field maintenance. All rings and tapered rollers adopt integral quenched GCr15 high-carbon chrome bearing steel, high hardness, excellent wear resistance and impact resistance. Widely matched for heavy industrial gear reducers, construction machinery drive axles, metallurgical auxiliary transmission shafts, mining conveyor equipment and wind power auxiliary speed reduction boxes.

8.FAQ

• Q1: What is the core difference between T7FC080-XL and T7FC080/QCL7C?
  A1: Same installation overall dimensions; T7FC080-XL is X-life anti-fatigue upgraded version, optimized raceway and roller matching for 24h uninterrupted heavy load production equipment with longer service life; T7FC080/QCL7C adopts Q logarithmic contact curve + CL7C surface treatment, ultra-low friction torque, low noise and low temperature rise, suitable for high-precision heavy transmission gearboxes.
• Q2: What loads can T7FC080 series bearings bear?
  A2: It bears heavy radial load plus unidirectional axial thrust load; bidirectional axial positioning requires two bearings installed back-to-back or face-to-face with reasonable preload.
• Q3: What is the advantage of separable tapered roller bearing structure?
  A3: The inner ring with roller and cage assembly can be separated from outer ring, convenient for assembly on heavy-duty shafts and prevents scratches on bearing raceways during installation and disassembly.
