Food-Grade & Sanitary Tungsten Carbide Bushings, Shaft Sleeves, Step Sleeves & Wear Components
$37.98
Zero Contamination. Extreme Wear Resistance. Sanitary Compliance! 🥦🥛Eliminate product contamination and premature pump failure in food processing and beverage canning. Panda Carbide Technology CO., LTD. manufactures precision Food-Grade Tungsten Carbide Bushings, Shaft Sleeves, Step Sleeves, and Wear Pins engineered for high-pressure homogenizers, sanitary pumps, and filling equipment.
Formulated with 100 % virgin sub-micron tungsten carbide powder and nickel/cobalt binder matrices, our sanitary sleeves undergo Overpressure HIP Sintering ( 1,450 °C ) to achieve an ISO 4499 A00 porosity rating. Featuring ultra-smooth mirror-polished inner/outer diameters ( Ra ≤ 0.02 - 0.05 μm ), Panda Carbide wear parts prevent product entrapment, withstand CIP (Clean-in-Place) acid/alkaline washdowns, and ensure smooth, contamination-free continuous operation.

1. Technical Specifications & Custom Configurations (Product Specs)
2. Material Recommendation Guide for Food & Pharma Processing
To meet strict FDA/sanitary standards and extend machine lifespan, select your binder matrix based on chemical media:
1. Corrosion-Resistant Nickel-Binder Carbide (YN6 / YN8 / YN10) — Recommended for Acidic Foods & CIP Sterilization:
Composition: WC + Nickel Binder matrix.
Best For: Fruit juices, dairy products, sauces (tomato/vinegar-based), and CIP acid/caustic washdowns ( pH 2 - 12 ).
Key Advantage: Eliminates Cobalt leaching, ensuring zero metal ion contamination into liquid food products while maintaining high wear resistance ( 89.5 - 91.5 HRA ).
2. High-Hardness Cobalt-Binder Carbide (YG6 / YG8) — Recommended for High-Pressure Homogenizers:
Composition: Sub-micron WC + Cobalt Binder.
Best For: Abrasive food slurries, chocolate grinding, grain milling, and high-pressure homogenizer plungers ( >30 MPa ).
Key Advantage: Exceptional compressive strength ( >4,000 MPa ) and wear resistance against hard solid particles.
3. Core Technical Advantages & Engineering Highlights
Ultra-Mirror Polish ( Ra ≤ 0.02 μm ): Internal and external diameters are lapped with diamond paste to achieve a mirror finish. This smooth surface prevents food residue buildup, reduces friction, and allows easy Clean-in-Place (CIP) sanitation.
Overpressure HIP Sintered Micro-Purity: Sintered under high argon gas pressure to remove all micro-voids (ISO 4499 A00 rating), eliminating microscopic bacterial harbor points.
Sub-Micron Concentricity ( ≤ 0.002 mm ): CNC cylindrical grinding ensures exact runout alignment, preventing shaft vibration, fluid leakage, and seal wear in high-RPM sanitary pumps.
4. Technical Q&A
Q: Why are Nickel-binder tungsten carbide bushings preferred over standard steel or bronze bushings in food and dairy processing equipment?
A: Standard steel or bronze bushings wear down rapidly under abrasive food slurries and corrode during chemical Clean-in-Place (CIP) washdowns, leading to metal particle contamination. Food-grade Nickel-binder tungsten carbide bushings from Panda Carbide Technology CO., LTD. offer superior hardness ( 89.5 - 92.0 HRA ) and chemical stability across pH 2 - 12 . Their mirror-polished surfaces ( Ra ≤ 0.02 μm ) eliminate product entrapment, prevent Cobalt leaching, and ensure zero-contamination operations in food, dairy, and beverage machinery.
5. Applications
- Primary Purpose: High speed rotating shafts, high-pressure pistons, and pump body sealing areas used in food, beverage, pharmaceutical, and fine chemical equipment provide extremely high wear resistance, erosion resistance, and anti bite protection to prevent metal debris from contaminating food or chemicals.
- Applicable Equipment: High-Pressure Homogenizers, Sanitary Screw Pumps, Centrifugal & Plunger Pumps, Food Filling & Seaming Machines, Food Grinding, Mincing & Emulsifying Machinery.
- Application Industries: Food & Beverage Processing, Dairy & Beverage Manufacturing, Pharmaceutical & Bio-Engineering, Fine Chemical & Cosmetic Packaging.
- Application Scenarios: Homogenizer plunger sleeves & valve seats, Bushings for viscous sauce & pulp pumping, Precision metering pins & push-rod sleeves in beverage canning.
