chmotion W3-2Z Dual V Groove Guide Wheel
Size 3 V-Groove Guide Wheel with Shielded Design & ABEC-3 Precision

Key Advantages

Dual V-groove design (A1/A2 radii): Provides precise tracking and alignment on V-shaped rails for smooth, stable linear motion.
Robust load capacity: Handles 5900N radial (Fr) and 1701N axial (Fa) working loads, with a 9500N dynamic rating (Cr).
Shielded (2Z) protection: Effective contamination exclusion with low friction, ideal for general industrial environments.
Precision engineering: ABEC-3 (P6) tolerance grade ensures reliable performance and reduced vibration.
Wide temperature range: Operates from -30°C to +100°C (-22°F to 212°F) with Shell Alvania EP2 grease.

Critical Specifications

Bore diameter (d): 12 mm
Outside diameter (D): 45.796 mm
Width (B): 15.88 mm
Gage wire distance (A): 49.596 mm
Basic static load rating (C0): 5900 N
Basic dynamic load rating (Cr): 9500 N
Weight (m): 0.1302 kg
Radial clearance: 0.010 – 0.022 mm

Design Features

Rings and balls made from 52100 (100Cr6) bearing steel for durability.
PA66 (nylon) cage for smooth operation at moderate speeds.
Shielded (2Z) with SPCC material; pre-lubricated with Shell Alvania EP2 grease.
Standard radial runout of 0.02 mm.

Industrial Applications

Linear guide systems on V-rails
Automation and pick-and-place units
Sliding doors and custom machinery
Material handling and conveyor guidance systems
