The UC201-UC210 series of outer spherical bearings (also known as insert bearings or pillow block bearings) are designed for robust performance in various industrial applications. These bearings feature a deep groove ball bearing housed in a cast iron or rubber-covered outer ring, providing durability, corrosion resistance, and adaptability to misalignment.

Available in iron cover (UC series) and rubber cover (UC-RS series) variants, these bearings are widely used in agricultural machinery, conveyor systems, fans, and other equipment requiring self-aligning capabilities and easy installation.

Key Features

1. Robust Construction

• Bearing Material: High-quality chrome steel for extended service life.

• Outer Ring:

  • Iron Cover (UC): Cast iron housing for heavy-duty applications.

  • Rubber Cover (UC-RS): Rubber-sealed for dust and moisture resistance.

2. Self-Aligning Design

• The spherical outer surface allows ±2°~3° misalignment compensation, reducing stress on shafts and housings.

3. Easy Installation & Maintenance

• Set screw (grub screw) locking mechanism ensures secure shaft fixing.

• Pre-lubricated with high-quality grease, reducing maintenance frequency.

4. Versatile Sealing Options

• Standard (Open): Suitable for clean environments.

• Rubber Sealed (UC-RS): Prevents dust, water, and contaminants, ideal for harsh conditions.
