3. Technical Description

This double-row track roller is engineered for applications involving guiding, supporting, or following tracks, rails, or linear paths.
The spherical outside surface allows the roller to compensate for:

• Misalignment
• Slight track irregularities
• Bending or deformation in guide rails

The double-row design increases load capacity and improves operational stability.

Dual covers/seals on both sides protect the internal raceways and balls from:

• Dust
• Moisture
• Contaminants

This ensures long service life in demanding environments.

The cage options (polyamide or sheet steel) provide reliable guidance of the rolling elements depending on speed, load, and application.

4. Typical Applications

Linear Motion & Track Systems

• Cam mechanisms
• Track guidance systems
• Linear conveyor tracks
• Sliding platforms

Industrial Machinery

• Packaging equipment
• Textile machinery
• Automation systems
• Handling equipment

Transport & Conveyor Technology

• Belt tensioners
• Guide wheels
• Load-carrying tracks

General Engineering

Ideal where:

• Radial + axial load support is needed
• Track-following precision is important
• Misalignment compensation is required

5. Key Advantages

• Double row construction → higher load capacity
• Spherical outer ring → compensates for track misalignment
• Sealed both sides → long service life
• Durable bearing steel → excellent fatigue strength
• Versatile cage options → suitable for both high-speed and high-load usage
• Excellent replacement for OEM track rollers in automation and conveyor systems
