1. Dimension Parameters (ISO 492 Standard)
- Bore (d): 70 mm (tolerance: −0.015/+0 mm)
- Outer diameter (D): 110 mm (tolerance: 0/+0.015 mm)
- Width (B): 20 mm (tolerance: ±0.05 mm)SKF 集团
- Chamfer (r₁.₂min): 1.1 mm; (r₃.₄min): 1.0 mm
- Weight: 0.62 kg
- Dynamic load rating (Cr): 76.5 kN
- Static load rating (C0r): 93.0 kN
- Limiting speed (grease): 6,300 rpm; (oil): 7,000 rpm
- Radial clearance: CN (normal)SKF 集团
- Precision class: P0 (ABEC 1, ISO standard)SKF 集团
- Axial displacement: ±1.3 mm
2. Material Specification
- Inner/outer rings: SKF 100Cr6 (AISI 52100) high-carbon chromium bearing steel. Hardness: 60–64 HRC; excellent rolling fatigue strength, wear resistance, and dimensional stability.
- Rolling rollers: 100Cr6 precision-grade steel. Hardness: 61–65 HRC; optimized line contact for high radial load capacity.
- Cage: Glass-fiber reinforced polyamide 66 (PA66) (SKF ECP design). Roller-centered, low friction, high-speed stability, and resistance to abrasion.
3. Core Manufacturing Process
- Hot closed-die forging: Refined grain structure for enhanced mechanical integrity.
- CNC turning: Dimensional precision ≤ ±0.003 mm for tight geometric tolerances.
- Vacuum heat treatment: Uniform hardening/tempering, minimal distortion, consistent hardness.
- Precision grinding: Raceway surface roughness Ra ≤ 0.16 μm.
- Superfinishing: Raceway honing (Ra ≤ 0.05 μm) to reduce friction and improve lubricant retention.
- Automated assembly: Strict roller guidance and dynamic balancing for consistent performance.
4. Service Life
- Standard rating life (L10): 13,000–16,000 hours (ISO 281:2007; radial load 55% Cr, 1,800 rpm, clean NLGI 2 grease).
- Key factors: Lubrication quality, contamination, operating temperature (-40°C to +120°C), shaft hardness (≥58 HRC), and alignment accuracy.
5. Applications & Industries
- Industrial gearboxes: Helical/bevel reducers (high radial load, separable design).
- Electric motors & generators: High-speed rotors (low friction, thermal stability).
- Pumps & compressors: Centrifugal/reciprocating units (continuous heavy load).
- Automotive: Transmissions, engine crankshafts (bi-directional axial displacement).
- Mining & construction: Conveyors, crushers (shock load resistance, durability).
- Machine tools: Spindle gear drives (precision, high-speed stability).
6. Maintenance & Lubrication
- Lubricant: NLGI 2 lithium complex grease (SKF LGMT3) or ISO VG 68–100 mineral oil.
- Regreasing interval: 2,000–2,500 hours; 800 hours in contaminated environments.
- Grease quantity: 10–12 g (35–40% of internal free space).
- Inspection: Every 800 hours; check noise, vibration, operating temperature (<75°C), and seal condition; clean with petroleum ether if contaminated.
7. Installation Guidelines
- Pre-installation: Clean shaft/housing to Ra ≤ 1.6 μm; inspect for burrs, corrosion, and dimensional conformity.
- Mounting: Induction heating (85–95°C) for inner ring; hydraulic press (max 60 kN) for outer ring; avoid direct impact.
- Alignment: Radial misalignment ≤ 0.002 mm/100 mm; axial runout ≤ 0.004 mm.
- Fastening: Lock nut torque: 75–85 Nm (grade 8.8 bolts).
- Post-installation: Manual rotation check; temperature rise <30°C above ambient; vibration testing for smooth operation.
