Design Features & Performance Benefits
- High Radial Load Capacity: Thick-walled outer ring design enables it to withstand substantial radial loads while minimizing distortion and bending stresses.
- Axial Load Absorption: Integral flange (stud head) and pressed-on flange ring allow absorption of axial loads from both directions, compensating for alignment errors or misalignment.
- Easy Mounting: Features a solid, threaded stud (M16×1.5) instead of an inner ring, enabling direct installation without requiring a housing bore.
- Durable Construction: Double-row full complement cylindrical rollers maximize load distribution and service life.
- Enhanced Protection: Steel seals on both sides prevent contamination ingress and retain lubrication, extending maintenance intervals.
- Crowned Running Surface: The outer ring is crowned to reduce edge stress and wear in applications where slight tilting relative to the track may occur.
- Relubrication Capability: Designed with relubrication holes for in-service maintenance and extended operational lifespan.

Applications
The F-53125.02.NUKR is primarily designed for use in:
- Heidelberg Printing Machines: Specifically engineered as a replacement part for Speedmaster CD102, SM102, and SX102 offset printing presses, where it serves critical functions in paper feed and delivery mechanisms, cam systems, and roller guidance.
- General Industrial Use: Conveyor systems, linear guidance mechanisms, cam-driven machinery, and other applications requiring precise, low-friction motion with high load capacity.
- Automotive: Though most commonly associated with printing machinery, this bearing design is also suitable for certain transmission and powertrain applications requiring compact, high-load components.
Operational Considerations
- Mounted on a flat (counter) track rather than in a housing bore
- Pre-lubricated with high-performance grease for initial operation; relubrication recommended for long-term use
- Operating temperature range: -30°C to +120°C (standard configuration)
- Ideal for moderate to high-speed applications with proper lubrication and maintenance
This INA cam follower represents a perfect balance of precision engineering, durability, and ease of installation, making it a preferred choice for demanding industrial applications worldwide, particularly in the printing industry where reliability and performance directly impact production efficiency.
