3. Technical Description

This single-row cylindrical roller bearing features a solid brass cage, making it a premium choice for heavy-duty applications requiring:

• High load capacity
• Excellent shock resistance
• Compatibility with elevated temperatures
• Superior lubrication stability

Key Technical Characteristics

✔ Brass Cage

• High mechanical strength
• Outstanding stability at high speeds
• Resistant to wear, vibration, and lubricant deterioration
• Ideal for heavy-load, impact, or high-temperature environments

✔ Floating Bearing Design

Allows free axial displacement, preventing internal axial stress from thermal expansion.

✔ Removable Inner Ring

Facilitates mounting/dismounting and supports tight fits in precision assemblies.

✔ Normal Radial Clearance

Standard for general-purpose industrial machinery.

Manufactured in Germany, this bearing combines precision engineering, robust cage construction, and optimized roller geometry for long, reliable performance in demanding applications.
