LR5205-2Z

chmotion LR5205-2Z Double Row Cam Follower Roller
High-Load Yoke Track Roller with 25mm Bore, Crowned Running Surface & Shields

Key Advantages

• Double row & crowned surface: Provides exceptional load distribution, higher rigidity, and smoother motion on uneven tracks compared to single-row rollers.
• Outstanding load capacity: Withstands high static (21.6 kN) and dynamic (15.3 kN) radial loads for demanding applications.
• Effective protection: Features 2Z non-contact shields on both sides to block contaminants while maintaining low running torque.
• Precision performance: Manufactured to P6 (ABEC-3) tolerance for reliable, smooth, and precise operation.
• Proven durability: Constructed from high-grade 100Cr6 bearing steel and lubricated with long-lasting Shell Alvania EP2 grease.
