20 Series Conductive Stainless Steel Caster

20 Series Conductive Stainless Steel Caster

Certified ESD Protection | Non-Marking Grey Tread | Rust-Free Sterile Structure | Vibration-Dampening Quiet Glide
Heavy-duty Conductive Stainless Steel Caster | Chinese Conductive Stainless Steel Caster Supplier | OEM & ODM Available

Basic Information

• Available Sizes: 3″, 4″, 5″, 8″

• Load Capacity: 250-400KG

• Our Heavy Duty Grey Conductive Stainless Steel Casters are engineered for strict Electrostatic Discharge (ESD) protected areas and sterile cleanrooms. Featuring a specialized non-marking grey conductive tread chemically bonded to a heavy-duty core, these casters deliver a reliable surface resistance below 10⁵ Ω to prevent static buildup. Housed in rust-proof Grade 304/316 stainless steel brackets and equipped with sealed stainless steel precision bearings, they support load capacities up to 400 kg per unit while ensuring flawless mobility, total corrosion resistance, and complete floor protection.

Key Features

1. Dual Protection (ESD + Floor Aesthetics): Eliminates the forced compromise between static safety and floor cleanliness. It provides a highly conductive path to ground for equipment like AGVs and PCB racks, while completely maintaining the pristine look of expensive epoxy coatings or vinyl cleanroom tiles.

2. Oil, Grease & Chemical Immunity: Polyurethane is exceptionally resistant to petroleum products, lubricants, cutting fluids, and mild acids, making these casters highly durable in industrial workshops and automotive plants where spills are common.

3. Enduring Cleanroom Compliance: Designed to withstand the rigorous standards of ISO cleanrooms and pharmaceutical plants. The specialized compound does not shed micro-particles (low-sloughing) and perfectly endures constant exposure to isopropyl alcohol (IPA), hydrogen peroxide vapor, and industrial disinfectants.

4. Anti-Static Safety for Sensitive Components: By providing a continuous, reliable pathway to ground, these casters prevent catastrophic electrostatic damage to sensitive microchips, surface-mount components (SMD), and highly calibrated laboratory instrumentation during transit.

Where to Use Our Casters

• Food Processing & Catering: Perfect for kitchen prep tables, food carts, and bakery racks that undergo frequent washdowns.

• Electronics & Semiconductor Assembly: Essential for PCB transport carts, SMD component racks, and clean bench equipment in ESD-protected areas (EPAs).

• Pharmaceutical & Bio-Tech Cleanrooms: Ideal for mobile laboratory scales, sterilization racks, and chemical mixing carts where static sparks pose an explosion hazard.

• Medical Operating Rooms: Perfect for high-end surgical equipment, diagnostic monitors, and life-support carts that generate heavy static in dry, air-conditioned hospital zones.
