FAG 32056-X-XL is a high-performance single-row tapered roller bearing from Schaeffler Group, featuring X-life premium technology for enhanced load capacity and extended service life. Engineered to DIN ISO 355 standards, this separable bearing delivers exceptional radial and axial load capacity, high rigidity, and precise shaft guidance, making it an optimal solution for heavy-duty industrial machinery operating under extreme conditions.
Dimension Parameters
Bore (d): 280 mm; Outer diameter (D): 420 mm; Width (B): 87 mm; Inner ring rib diameter (d₁): 347 mm; Minimum chamfer (r₁,₂/r₃,₄): 5 mm / 4 mm; Tolerance class: P0 (ABEC 1); Dynamic load (Cr): 1,420 kN; Static load (C₀r): 2,300 kN; Limiting speed (grease): 1,510 rpm; Weight: 40.5 kg.
Material Specification
- Rings & Rollers: AISI 52100 (100Cr6) bearing steel, hardness 61–65 HRC, offering superior rolling fatigue strength, wear resistance, and dimensional stability.
- Cage: High-strength stamped steel (JIS S55C), precision-formed for stable roller guidance and reduced friction under heavy loads.
- Surface: Black oxide finish enhances corrosion resistance and lubricant adhesion.
Core Manufacturing Process
- Hot forging: Optimizes grain structure for maximum load-bearing integrity.
- CNC machining: Ensures strict dimensional accuracy and geometric precision.
- Vacuum heat treatment: Delivers uniform hardness, minimal distortion, and enhanced toughness.
- Superfinishing: Raceway roughness Ra ≤ 0.2 μm, optimizing lubrication and minimizing wear.
- X-life optimization: Advanced profile and surface treatment boost rated life by over 50% vs. standard designs.
Service Life
Under ISO 281 standard conditions (40% rated load, 1,000 rpm, proper lubrication), rated life ≥9,500 hours. Key factors: lubricant purity, operating temperature (-30°C to 120°C), alignment accuracy, and contamination controlFAG轴承.
Applications & Industries
Ideal for gearboxes, rolling mills, crushers, conveyors, and heavy machinery. Serves mining, metallurgy, construction, cement, and pulp & paper industries. Its high combined load capacity, X-life durability, and rigid axial guidance excel in heavy shock loads and harsh environmentsFAG轴承.
Maintenance
- Lubrication: NLGI 2 EP lithium complex grease, fill 30–40% of internal space; replenish every 1,200–1,500 hours.
- Inspection: Monthly vibration (<2.8 mm/s) and temperature (<85°C) checks.
- Cleanliness: Maintain sealing integrity; prevent abrasive particle ingress.
Installation
1. Prep: Clean shaft/housing; verify hardness ≥55 HRC and roughness Ra ≤1.6 μm.
2. Mount: Use hydraulic press or induction heating (<120°C); avoid direct hammering.
3. Alignment: Radial runout ≤0.03 mm; adjust internal clearance per FAG specifications.
4. Post-install: Test run for 2 hours; confirm smooth rotation and stable temperature.
FAG 32056-X-XL stands as a top-tier X-life tapered roller bearing for heavy-duty industrial applications, providing unmatched reliability, load capacity, and service life in the most demanding operating conditions.
