3. Technical Description

This high-performance Explorer-series cylindrical roller bearing is engineered for applications requiring high load capacity, low friction, and excellent running accuracy.

The bearing features:

✔ Single-row cylindrical roller design

Optimized for high radial loads, offering excellent stiffness and long service life.

✔ Floating bearing function

Allows axial displacement between shaft and housing, ideal for thermal expansion in rotating machinery.

✔ Removable inner ring (both sides)

• Facilitates mounting
• Perfect for applications requiring easy assembly/disassembly
• Suitable for tight tolerance fits

✔ Polyamide cage

• High-speed capability
• Reduced friction and heat generation
• Quiet running behavior

✔ Explorer Series Upgrade

Improved steel quality, refined roller geometry, and enhanced surface finish deliver:

• Higher load rating
• Lower operating temperature
• Extended bearing life

4. Typical Applications

• Electric motors
• Gearboxes
• Pumps and compressors
• Fans and blowers
• Machine tools

Heavy-Duty Equipment

• Processing machinery
• Industrial drives
• Steel and paper mills

Power Transmission Systems

• High-speed rotating shafts
• High radial load supports

General Mechanical Engineering

Ideal where:

• High radial loads are present
