Product Description

Why Choose the 22216 Bearing for Heavy-Duty Applications?

The 22216 bearing is a double-row self-aligning roller bearing engineered to handle medium-to-heavy radial loads and moderate axial loads in demanding environments. With an 80mm bore, 140mm outer diameter, and 33mm width, this bearing excels in industries like metallurgy, mining, and paper manufacturing where equipment faces extreme heat, dust, and vibration. At LUOYANG INNO, we combine 30+ years of manufacturing expertise to deliver bearing products that ensure reliable performance under high stress.

Key Advantages

  • Self-Aligning: Compensates for shaft misalignment up to 3°, reducing bearing wear in unevenly loaded systems.
  • High-Temperature Resistance: Optional heat-treated GCr15 steel 22216 bearing variants withstand extreme thermal conditions.
  • Rapid Customization: Get non-standard roller bearing configurations in 15 days, with prototypes ready in 7 days.

Industry-Proven Applications

  • Mining Equipment: 22216 bearing units withstand shock loads in crushers and vibrating screens.
  • Metallurgy Machinery: Specialized heat treatment ensures reliable bearing operation in 200°C+ environments.
  • Paper Manufacturing: Sealed roller bearing variants resist humidity and chemical exposure in dryer sections.

Quality & Logistics

Every bearing undergoes raw material hardness testing (58–62 HRC), 3D profile scanning, and 72-hour endurance testing. We provide 48-hour shipping for standard models and IoT-enabled predictive maintenance tools.

FAQs

Q: Can I get the 22216 bearing with a tapered bore?
A: Yes! We offer 1:12 tapered bore roller bearing variants for easier installation on 80mm shafts.

Q: How do you ensure longevity in dusty environments?
A: Our 22216-S model includes triple-lip seals and upgraded grease for 5x longer dust resistance in bearing assemblies.

Q: What certifications do your bearing products have?
A: All units meet ISO 9001, CE, and API 613 standards, with ATEX and MSHA available on request.
