PORDUCT OVERVIEW

chmotion W4-2RS V Groove Guide Wheel
Dual V-Groove Track Roller, Size 4, with Sealed ABEC-3 (P6) Precision

Key Advantages

  • Dual V-groove design: Provides precise tracking and alignment on common V-profile rails for smooth, guided linear motion.
  • Robust sealed construction (2RS): Features dual rubber contact seals (NBR) to effectively retain grease and exclude contaminants, enhancing service life in demanding environments.
  • High load capacity: Supports substantial working loads of 9700N radial (Fr) and 4001N axial (Fa) for versatile application strength.
  • Standard Size 4 compatibility: A widely used dimension (15mm bore, ~60mm OD) ensuring easy integration and replacement within existing systems.
  • Premium 52100 steel construction: Manufactured from high-carbon chromium bearing steel (100Cr6) for superior durability and wear resistance.

Critical Specifications

  • Bore diameter (d): 15 mm
  • Outside diameter (D): 59.944 mm
  • Width (B): 19.05 mm
  • V-groove radii (A1/A2): 25.4 mm / 34.93 mm
  • Basic dynamic load rating (Cr): 14400 N
  • Basic static load rating (C0): 9700 N
  • Weight: 0.276 kg
  • Temperature range: -30°C to +100°C (-22°F to +212°F)

Design Features

  • Sealing Solution: Dual rubber contact seals (2RS) with NBR material.
  • Components: Rings and balls made from 52100 steel; cage from PA66 polymer.
  • Lubrication: Pre-lubricated with Shell Alvania EP2 grease.
  • Precision: ABEC-3 (P6) tolerance class with controlled radial runout.
  • Compliance: Ideal for general industrial use.

Industrial Applications

  • Linear guide and track systems
  • Automation equipment and sliding doors
  • Conveyor system guides and trolleys
  • Packaging and material handling machinery
  • CNC router and gantry system supports
