LR5303-2Z

chmotion LR5303-2Z Yoke Track Roller (Cam Roller)
Double Row, Cylindrical Running Surface with Shields on Both Sides

Key Advantages

• Double row design & high radial load: Delivers a maximum dynamic radial load (Fr) of 15.5 kN for stable, high-capacity performance.
• Robust static load capacity: Supports up to 22.14 kN static radial load (F0r), ideal for heavy-duty, stationary applications.
• Effective sealing with 2Z shields: Protects against contaminants on both sides, extending service life in demanding environments.
• P6 (ABEC-3) precision: Ensures smooth and accurate linear or oscillating motion with controlled runout and tolerances.
• Wide temperature range: Operates reliably from -20°C to +120°C (-4°F to +248°F) with Shell Alvania EP2 grease.
