Dimension Parameters (ISO Standard)
Bore (d): 45 mm; Outer diameter (D): 85 mm; Width (B): 23 mm; Minimum chamfer radius (rmin): 1 mm; Tolerance class: P0 (ABEC 1); Dynamic radial load (Cr): 79.7 kN; Static radial load (Cor): 78.7 kN; Limiting speed (grease): 3,800 rpm; Weight: 0.59 kg; Misalignment tolerance: 1°; Equipped with W33 lubrication groove and 3 oil holes.
Material Specification
- Inner/Outer Ring & Rollers: AISI 52100 (100Cr6/GCr15) high-carbon chromium bearing steel, hardness 61–65 HRC, delivering exceptional rolling fatigue strength, wear resistance, and dimensional stability.
- Cage: High-quality carbon steel (JIS S45C) stamping, precision-formed for stable roller guidance and reduced friction.
- Seal: Double-sided Lambda® NBR rubber seals, providing excellent exclusion of dust, moisture, and contaminants.
Core Manufacturing Process
- Hot forging: Refines grain structure for enhanced mechanical integrity and load resistance.
- CNC precision machining: Ensures strict adherence to dimensional tolerances.
- Vacuum heat treatment: Achieves uniform hardness, minimized distortion, and improved toughness.
- Precision grinding & superfinishing: Raceway roughness Ra ≤ 0.2 μm, optimizing lubrication film formation and reducing noise.
- Automated assembly & 100% inspection: Validates clearance, seal performance, and rotational smoothness.
Service Life
Under ISO 281 standard conditions (40% rated load, 2,500 rpm, proper lubrication), rated life ≥7,500 hours. Key influencing factors: lubricant cleanliness, operating temperature (-30°C to 150°C), shaft misalignment, and external contamination.
Applications & Industries
Ideal for conveyors, crushers, mixers, agricultural machinery, vibrating screens, fans, and pumps. Serves mining, construction, agriculture, steel, and general manufacturing industries. Its superior self-alignment (up to 1°), high load capacity, and robust sealing make it perfectly adapted to heavy shock loads and harsh, dusty conditions.
Maintenance
- Lubrication: NLGI 2 lithium complex or extreme pressure (EP) grease, fill 30–40% of internal voids; relubricate via W33 holes every 1,000–1,200 hours.
- Inspection: Monthly checks for abnormal noise, vibration (>2.5 mm/s), and temperature (>80°C).
- Cleanliness: Maintain seal integrity; prevent ingress of abrasive particles.
Installation
1. Prep: Clean shaft/housing; verify shaft hardness ≥55 HRC and roughness Ra ≤1.6 μm.
2. Mount: Use mechanical or hydraulic press for even mounting; avoid impact hammering.
3. Alignment: Total indicator runout (TIR) ≤0.02 mm; utilize W33 lubrication features post-install.
4. Post-install: Rotate manually to confirm smooth operation; conduct a 1-hour test run and monitor temperature.
MCGILL SB22209-W33-YSS stands as a high-performance sealed spherical roller bearing for heavy-duty industrial machinery, offering exceptional durability, self-alignment, and low maintenance for the most demanding operational environments.
