1. Precise Dimension Parameters (ISO 492 / Inch Standard)
- Bore diameter (d): 30.162 mm (1-3/16″, tolerance: +0/-0.025 mm)
- Outer diameter (D): 38.10 mm (1-1/2″, tolerance: +0.025/-0 mm)
- Width (B): 15.88 mm (5/8″, tolerance: +0/-0.20 mm)
- Chamfer (rmin): 0.8 mm
- Weight: 0.0325 kg
- Precision class: Normal (ABEC 1, conforming to JIS B 1521)
- Basic dynamic load rating (Cr): 15.2 kN
- Basic static load rating (C0r): 22.5 kN
- Limiting speed (oil): 6,000 rpm; (grease): 4,800 rpm
2. Premium Material Specification
- Outer shell (drawn cup): High-carbon chromium steel SAE 52100 (100Cr6), carburized and quenched. Hardness: 58–62 HRC; high surface hardness, wear resistance, and dimensional stability.
- Needle rollers: SUJ2 (100Cr6) high-carbon bearing steel. Hardness: 61–65 HRC; excellent rolling fatigue strength and contact stress resistance.
- Cage: Cold-rolled steel (SPCC). Precision-formed for stable roller guidance, low friction, and high-speed capability.
3. Advanced Manufacturing Process
- Cold drawing: Precision thin-walled shell drawing for uniform wall thickness and ultra-compact cross-section.
- Carburizing heat treatment: Controlled case hardening for durable outer shell with tough core.
- CNC turning & grinding: Precision machining of raceways (roughness Ra ≤ 0.15 μm).
- Superfinishing: Honing of needle rollers (Ra ≤ 0.05 μm) to minimize friction and enhance lubrication retention.
- Assembly: Automated cage-guided roller assembly for consistent precision and operational stability.
4. Service Life Performance
- Standard rating life (L10): 12,000–16,000 hours under ISO 281:2007 conditions (radial load 60% of Cr, 1,500 rpm, clean oil lubrication).
- Key life factors: Lubrication quality, contamination level, operating temperature (-20°C to +100°C), shaft hardness (min. HRC 58), and surface finish (Ra ≤ 0.2 μm).
5. Target Applications & Industries
- Automotive: Small transmissions, gearboxes, motorcycle engines, and steering components (compact design, high radial load).
- Hydraulics & pneumatics: Pumps, compressors, small actuators (low friction, high-speed capability).
- Industrial equipment: Office machinery, textile machines, power tools (lightweight, space-saving).
- Agricultural & small engines: Lawn equipment, small motor assemblies (shock load resistance, durability).
- Material handling: Conveyor rollers, small gear drives (cost-effective, long service life).
6. Maintenance & Lubrication
- Lubricant: ISO VG 46–68 mineral oil or NLGI 2 lithium grease (Mobilux EP 2).
- Regreasing interval: 1,200–1,500 operating hours; 400 hours under heavy contamination.
- Grease quantity: 2.5–3.0 g (40–45% of internal free space).
- Inspection: Every 400 hours; check noise, vibration, temperature (<70°C), and contamination; clean with petroleum ether if dirty.
7. Installation Guidelines
- Pre-installation: Clean housing bore to Ra ≤ 1.6 μm; inspect for burrs or deformation.
- Mounting: Press-fit outer shell with hydraulic press (max force: 15 kN); avoid hammering.
- Shaft requirements: Hardness HRC 58–62, surface finish Ra ≤ 0.2 μm; radial misalignment ≤ 0.003 mm/100 mm.
- Post-installation: Rotate manually to confirm smooth operation; temperature rise <25°C above ambient.
