Why Choose the NX Caster?
The NX Caster combines a high-capacity polymer wheel with a corrosion-resistant 316 stainless steel fork and a Delrin bearing. The non-marking NX wheel prevents floor damage, unlike metal wheels that can mark or dent surfaces. Its compression-molded design avoids flat spots, a problem with polyurethane wheels under heavy, static loads. The 316 stainless steel fork thrives in harsh environments, resisting rust from chemicals, saltwater, or moisture. The Delrin bearing, made from high-lubricity plastic, rolls smoothly in wet or caustic conditions and resists degradation. While not frictionless, it performs reliably under heavy loads, though it will require slightly more push than precision ball bearings. This caster shines in settings where durability and floor protection are critical. Its flat tread face evenly distributes weight, reducing wear on floors and equipment. The combination of the NX wheel, 316 stainless steel fork, and Delrin bearing ensures long-lasting performance in tough conditions like manufacturing plants or food processing facilities. For custom needs or technical support, contact our engineering team at Caster City or call 800-501-3808.

  • Automated Guided Vehicles (AGVs): Provides dependable rolling for robotic transport systems.
  • Medical Equipment: Protects hospital or lab floors while moving heavy machinery.

Technical Details
The NX Polymer Caster Wheel is compression molded and machined for precision. This process keeps the wheel strong under heavy loads, avoiding flat spots or delamination common in polyurethane wheels. The wheel’s straight-sided design maximizes its 1250-pound load capacity. Available in 4”, 5”, and 6” diameters, all 2” wide, the NX wheel offers flexibility for various equipment sizes. Its flat tread face ensures stable contact with the ground, reducing wobble and distributing weight evenly. The SS316-9 fork, made from 316 stainless steel, offers superior corrosion resistance compared to standard steel or 304 stainless steel. It stands up to moisture, chemicals, and saltwater, making it ideal for harsh environments. The Delrin bearing enhances performance in wet or caustic settings, where metal bearings might rust or fail. Its high lubricity ensures smooth rolling, especially when wet, though it may require slightly more effort to start moving under maximum load due to its non-frictionless design. The caster operates in temperatures from -20°F to 180°F, with the NX wheel’s approximate melting point at 500°F. This range suits cold storage or standard indoor environments. The wheel’s 80 Shore D hardness provides durability while protecting smooth surfaces like concrete, tile, or epoxy-coated floors from marks or scratches.

Customization Options
The NX Caster is available in 4”, 5”, and 6” diameters, all 2” wide, with Delrin bearings for consistent performance. For specialized applications, such as extreme temperatures or unique mounting requirements, our engineering team can provide tailored solutions. Contact Caster City or call 800-501-3808 to discuss your needs. Caster City also offers a top lock wheel brake, with pedal on the side of the wheel, also made out of 316 stainless steel as an add-on option for this caster.

Benefits Over Traditional Casters
The NX Caster outperforms traditional metal or polyurethane casters. Metal wheels often scratch or dent floors, while polyurethane wheels can develop flat spots under heavy loads. The NX wheel’s non-marking polymer and compression-molded design eliminate these issues. The 316 stainless steel fork resists corrosion better than standard steel, ensuring longevity in harsh conditions. The Delrin bearing, while not frictionless, excels in wet or chemical environments where metal bearings may fail. This caster’s ability to handle 1250 pounds while protecting floors makes it a top choice for industries needing durability and reliability.

Installation and Maintenance
Installing the NX Caster is simple, with the SS316-9 fork designed for standard mounting plates. Ensure the mounting surface is clean and secure to support the 1250-pound capacity. For maintenance, check the Delrin bearing for wear and clean the wheel to remove debris. In wet or chemical environments, rinse the caster regularly to prevent buildup. This caster comes with a grease fitting in the axle and in the swivel bearing of the caster to grease all moving parts.  For detailed installation or maintenance tips, reach out to Caster City.

 

FAQ

FAQ for 316 Stainless Steel Casters (Model 9)

Why should I choose 316 stainless steel casters over 304 stainless steel casters?
316 stainless steel casters, like our Model 9, are made for harsh environments where 304 won’t hold up. The 2-3% molybdenum in 316 provides superior resistance to chlorides, acids, and caustic cleaning agents. This makes it essential for marine applications, chemical processing plants, pharmaceutical manufacturing, food processing facilities (especially those using caustic cleaners or salt), and water treatment facilities. 304 is okay for milder settings, but 316’s enhanced corrosion resistance is key where failure isn’t an option.
