Product Description

Non-Magnetic Tungsten Carbide Guide Bushing
WC-Ni Alloy Precision Linear Bushing for Sensitive Environments
Product Overview
When machinery operates in magnetic-sensitive environments—such as semiconductor wafer handlers, MRI patient positioning systems, or high-precision measurement equipment—standard bushings become a liability. Our Non-Magnetic Tungsten Carbide Guide Bushings are engineered to be the perfect solution. Crafted from specialized WC-Ni (Tungsten Carbide-Nickel) alloy, these bushings deliver the ideal combination of absolute magnetic neutrality, exceptional wear resistance, and micron-level precision for linear and rotary motion systems.
Core Technology
  • Guaranteed Non-Magnetic Performance (µ < 1.002): By utilizing a nickel-based binder system instead of conventional cobalt, our bushings are completely free of ferromagnetic elements. This ensures zero magnetic attraction to ferrous particles, no interference with sensitive magnetic fields (MRI, electron beams, sensors), and compatibility with cleanroom and high-vacuum environments where magnetic materials are prohibited.
  • Unmatched Wear Resistance & Longevity: With a hardness of 90-92 HRA, WC-Ni alloy provides wear resistance that exceeds tool steel by a factor of 50-100x. This means consistent precision over millions of cycles without bushing wear, elimination of play or slop that develops in steel bushings over time, and reduced maintenance intervals with lower total cost of ownership.
  • Superior Surface Finish & Low Friction: Our advanced polishing capabilities achieve mirror finishes down to Ra 0.1 μm, providing minimal friction against mating shafts (ideal for high-speed applications), excellent lubricant retention when grooves are specified, and reduced particle generation compared to porous or coated alternatives.
  • Exceptional Thermal & Dimensional Stability: With a low coefficient of thermal expansion (~5.5 × 10⁻⁶/K) and high elastic modulus (~630 GPa), these bushings maintain their precise geometry across temperature variations and under heavy loads.
