85x170x48mm T7FC085-XL Long Life Tapered Roller Bearing T7FC 085/QCL7C 3950RPM

1. Product Overview

1.Product Overview
T7FC085-XL is ISO355 standard T7FC series single row separable tapered roller bearing with X-life upgraded optimization, unified metric dimension inner bore d=85mm, outer diameter D=170mm, inner ring width B=45mm, outer ring width C=33mm, total assembly width T=48mm, built-in 30° large contact angle structure.
Suffix XL stands for X-life premium upgrade process: ultra-precision superfinished raceway, classified uniform tapered rollers, optimized internal geometry and stress relief heat treatment, greatly lifting fatigue limit load and extending service life for 24-hour non-stop heavy-duty production equipment.
Fully split separable design: the integrated assembly of inner ring, tapered rollers and stamped steel cage can be completely detached from outer ring, simplifying shaft installation, disassembly and field maintenance. All rings and rolling elements adopt integral quenched GCr15 high-carbon chrome bearing steel, high hardness, low friction and outstanding wear resistance. Widely applied to heavy industrial gear reducers, construction machinery drive axles, metallurgical auxiliary transmission shafts, mining conveyor equipment and wind power auxiliary speed reduction boxesschaeffler....

3. Key Advantages

1. Exclusive X-life upgraded XL technology, optimized surface finish and internal stress structure, higher anti-fatigue performance than standard T7FC085, perfect for long-cycle uninterrupted heavy load operation
2. 30° large contact angle tapered roller layout, strong combined bearing capacity for heavy radial load + unidirectional large axial thrust load, stable low-vibration rotation under frequent forward/reverse impact loads
3. Fully separable split construction, inner roller-cage assembly detached from outer ring, easy mounting and removal on heavy-duty shafts without scratching bearing race surfaces during assembly
4. Precision mirror superfinished cone raceway reduces friction torque and heat accumulation at high speed, effectively avoid high-temperature ablation failure under long-time heavy load
5. Dual cage selections: stamped steel cage cost-effective for general heavy load scenarios; brass cage anti-deformation for high-temperature 24h continuous production lines
6. Customizable options: C3 enlarged radial clearance, P5 high precision grade, OEM laser marking, special high-temperature anti-oxidation grease filling

Effectively extend overhaul intervals of heavy gearbox, construction and metallurgical transmission equipment, cutting production downtime maintenance losses
