Sealed Spherical Roller Bearings

1. Feature: Spherical roller bearings, whose inner ringss have two raceways, and outer race-ways are spherical. The centers of curvature of outer raceways are alse the bearing centers. The bearings possess self-aligining performance, the permissible disalignment angle is 1-2.5°, and can be used in certain permanent deflective application.
These bearings are able to carry high radial loads, as well as axial loads at the same time, but not pure axial loads, the axial carrying bearing will be needed if axial loads were higher. The contact between rollers and raceways are so close, so the friction is higher than cylindrical roller bearings, and their limiting speed is lower.
2. Application:
Spherical roller bearings are primarily used in such application as rolling mills, paper making machines,power-driven gears, shipping and so on.
3. Sizes:Inner Diameter: 150-1060mm
Outer Diameter: 225-1400mm Weight: 8.91-1020kg
4: Type: 20000C, 20000C/W33, 20000CA/W33
5. Material: GCr15/GCr15SiMn/G20Cr2Ni4A

 What are Sealed Spherical Roller Bearings?

Sealed spherical roller bearings are advanced components designed to support heavy loads and ensure smooth operation in demanding environments. Unlike standard spherical roller bearings, the sealed version includes a protective shield that prevents contaminants from entering the bearing, thus extending its service life and maintaining its performance under harsh conditions.

These bearings are engineered to handle radial and axial loads simultaneously and are particularly useful in applications where misalignment may occur. Their self-aligning feature makes them ideal for supporting rotating machinery in various industries.

Benefits of Sealed Spherical Roller Bearings

  1. Enhanced Durability: The sealing mechanism protects the bearing from dust, dirt, and moisture, significantly extending its service life.
  2. Improved Performance: Sealed bearings maintain consistent performance by preventing lubricant leakage and contamination.
  3. Reduced Maintenance: With better protection against environmental factors, the need for frequent maintenance is minimized.
  4. Self-Aligning Capability: They can accommodate shaft misalignments, making them ideal for heavy-duty applications.

Applications

Sealed spherical roller bearings are versatile and used in various sectors including:

  • Metallurgical Industry: Supporting equipment like blast furnaces and rolling mills.
  • Mining Machinery: Essential in crushers, screens, and feeders.
  • Heavy Industrial Equipment: Ideal for applications involving heavy loads and misalignment issues.
  • Agricultural Machinery: Used in combine harvesters and other farming equipment.

Installation Guide

  1. Preparation: Ensure the shaft and housing are clean and free from debris.
  2. Alignment: Properly align the bearing to prevent premature wear and failure.
  3. Lubrication: Apply appropriate lubricant as per the manufacturer’s recommendations.
  4. Mounting: Carefully press the bearing onto the shaft and into the housing, avoiding any direct impact.

Maintenance and Care

  1. Regular Inspections: Check for signs of wear, noise, or vibration regularly.
  2. Lubrication: Replenish lubricant as needed and follow the manufacturer’s guidelines for intervals.
  3. Cleaning: Keep the bearing area clean to avoid contamination.
  4. Monitoring: Use condition monitoring tools to detect potential issues early.

FAQ

Q: What makes sealed spherical roller bearings different from standard bearings? A: The key difference is the seal which prevents contaminants from entering, thus enhancing durability and reducing maintenance.

Q: Can these bearings be used in high-temperature environments? A: Yes, they are designed to operate effectively within a wide temperature range, typically from -40°C to +150°C.

Q: How often should sealed spherical roller bearings be replaced? A: Replacement frequency depends on operating conditions and maintenance practices. Regular inspections will help determine when replacement is necessary.
