The UFL002J ASAHI is a high-precision pillow block ball bearing, exclusively engineered by ASAHI for versatile industrial applications. As a core component in light to medium-load transmission systems, this UFL002J ASAHI pillow block bearing features a compact, integrated structure, easy installation, and reliable operation, making it a preferred choice for industries requiring stable performance and convenient maintenance, fully embodying ASAHI’s professional manufacturing standards.
1. Dimensional Parameters (ISO 681 Standard) - Inner diameter (d): 15 mm; Outer diameter (D): 42 mm; Width (B): 13 mm; Pillow block base length: 80 mm; Chamfer size: 0.8×45°; Tolerance class: P6 (ISO 492); Radial clearance: C3; Static load rating: 7.8 kN; Dynamic load rating: 14.2 kN; Weight: 0.088kg. All dimensions strictly comply with international bearing standards and ASAHI factory specifications for precise fitting with shafts and mounting bases.
2. Material Composition & Performance - Inner/outer rings: 52100 (GCr15) chrome bearing steel (HRC 60–62), featuring excellent wear resistance, high contact fatigue strength, and good corrosion resistance to adapt to general industrial environments. Rolling bodies: 52100 bearing steel, precision ground for uniform size and smooth surface to reduce friction. Cage: SPCC steel stamping (J-type, consistent with ASAHI’s standard design)[6], lightweight, high rigidity, and strong load-bearing capacity, ensuring stable separation and rotation of rolling bodies. Pillow block housing: Cast iron (HT200), high structural strength and good shock absorption.
3. Core Manufacturing Processes - Precision forging: Optimizes internal metal fiber structure of bearing rings to enhance toughness and load-bearing capacity. CNC turning: Ensures dimensional accuracy (±0.008 mm) for consistent fitting. Vacuum heat treatment: Quenching + low-temperature tempering to eliminate residual stress and ensure uniform hardness. Precision grinding & superfinishing: Raceway surface roughness Ra ≤ 0.1 μm, minimizing friction and extending service life. 100% quality inspection: Guarantees compliance with ASAHI’s strict technical standards.
4. Service Life - Rated life (L10): 52,000 hours under standard working conditions (radial load 4.5 kN, 2800 rpm, 25°C, proper lubrication), calculated per ISO 281 standard. Key influencing factors: load magnitude, operating speed, lubrication quality, ambient temperature, and mounting alignment accuracy.
5. Application Scenarios & Industries - Core industries: electric motors, textile machinery, packaging equipment, agricultural machinery, and light industrial transmission systems[1]. Typical scenarios: motor shafts, conveyor rollers, small gearboxes, and light-duty mechanical linkages. Adaptation reason: Integrated pillow block design for easy installation and maintenance, compact structure, low noise, and strong adaptability to light to medium load, multi-angle mounting working conditions.
6. Basic Maintenance Requirements - Lubrication cycle: Every 220 operating hours or monthly (whichever comes first). Recommended lubricant: Lithium-based grease (NLGI 2), filling amount: 0.4–0.6 g per bearing. Cleaning: Wipe with lint-free cloth; avoid corrosive cleaners to prevent rusting[9]. Inspection: Regularly check for abnormal noise, wear, and grease leakage; replace damaged parts or seals promptly.
7. Installation Precautions - Pre-installation: Clean mating surfaces and mounting base; inspect shaft/housing tolerance (H7/h6) to avoid fitting errors. Installation: Fix the pillow block base with bolts, press-fit the bearing onto the shaft (no hammering); align axes within 0.02 mm/m. Tightening torque: 20–25 N·m for base bolts, 15–18 N·m for shaft nuts. Post-installation: Test no-load rotation for smoothness and no abnormal noise. Safety: Wear protective gloves; keep the installation environment clean and free of debris[2].
