LR5205-X-2Z

chmotion LR5205-X-2Z Yoke Track Roller
Double-Row Cam Roller with 25mm Bore & Shields on Both Sides

Key Advantages

• Heavy-duty dual-row design: Provides superior stability and load distribution for demanding cam and track applications.
• Integrated shields on both sides (2Z): Effectively keeps contaminants out while retaining lubrication, ensuring longer service life.
• High-load capacity: Robust 21.6kN maximum static load (F0r) and 15.3kN maximum dynamic radial load (Fr).
• Precision P6 (ABEC-3) tolerances: Ensures smooth, consistent, and low-noise operation in precision motion systems.
• Wide temperature & grease compatibility: Operates from -20°C to +120°C with standard Shell Alvania EP2 grease.
