Description
4″ High Temp Glass Filled Nylon Wheel. Shown in photo with 5″ wheels. Economy Stainless Steel Stem Caster Model K3 is made using a stamped steel construction and is excellent for corrosive applications. This institutional stainless steel stem caster is assembled with a ⅜” diameter axle bolt, and This stem caster uses a ½” rivet to hold the swivel bearing together. Economy Stainless Steel Stem Caster Model K3 caster brackets have two rows of ball bearings rotating on raceways for smoother swiveling. This caster is excellent for washdown situations due to having no swivel bearing cover or a grease fitting, which helps facilitate water draining through the swivel bearing and raceways. This stem caster performs best if you limit the load to no more than 1000 lbs on a set of 4 Model K3 casters.
The NP High Temp Glass-Filled Nylon Wheel in the Stainless Steel Caster Model K3A is a great pick for light industrial casters, made from glass-filled nylon with additives to resist heat and moisture, crafted for 3”, 4”, and 5” diameters (1.25” wide) and holding up to 300 lbs per wheel at room temperature on smooth floors in moist high heat spots like steam autoclaves, food processing, and washdown areas. This hard, non-marking high heat caster wheel, NSF Listed and ROHS Compliant, takes continuous operation up to 475°F and 525°F for 30 minutes with a plain bore and spanner bushing for a 3/8” axle, giving reliable performance in moist high heat settings when shielded from direct heat sources like flames, ideal for stainless steel casters needing a high temperature wheel for tough jobs.
Built for moist high heat, these “NP” high temperature casters and wheels shine in wet heat settings with their cost-effective, food-safe design, keeping smooth rolling and floor protection in food processing or autoclave setups for institutional applications like animal labs or butcher tables. The non-marking surface and high temp durability make these stainless steel casters a smart choice for moist high heat environments, meeting NSF and ROHS standards for safe, eco-friendly use on smooth floors in extreme heat.

FAQ
Stainless Steel Stem Caster Model SS-K3A with 1.25-Inch Wide NP High Temp Glass-Filled Nylon Wheel
What material are “NP” high temperature wheels made from in the Stainless Steel Stem Caster Model SS-K3A for stainless steel casters?
The NP High Temp Glass-Filled Nylon Wheel in the Model SS-K3A stainless steel caster is made from glass-filled nylon with additives to resist heat and moisture, creating a hard, non-marking high temperature wheel for smooth rolling in moist high heat settings.
What applications are best for the stainless steel industrial caster with “NP” high heat casters in moist heat environments?
The stainless steel industrial caster with NP high heat casters and wheels is perfect for moist high heat applications, like steam autoclaves, food processing, and washdown areas, where stainless steel casters move loads on smooth floors in hot, wet zones.
What’s the temperature limit for the NP High Temp Glass-Filled Nylon Wheel in the stainless swivel caster for high temperature use?
The NP High Temp Glass-Filled Nylon Wheel in the stainless swivel caster takes continuous operation up to 475°F and can hit 525°F for 30 minutes max—cool it to room temperature after high heat use to keep its service life strong.
What sizes do the NP high temperature wheels come in for the Stainless Steel Stem Caster Model SS-K3A stainless steel casters?
The NP high temperature wheels in the Model SS-K3A stainless steel casters come in 3”, 4”, and 5” diameters, offering options for stainless high temp casters in moist high heat applications on smooth floors.
Can the NP High Temp Glass-Filled Nylon Wheel in the stainless steel industrial caster roll on rough floors as a high temp wheel?
No, the NP High Temp Glass-Filled Nylon Wheel in the stainless steel industrial caster is built for smooth floor surfaces only—rough floors or obstructions will damage these stainless steel casters and shorten their life.
Are the stainless steel casters with NP wheels good for dry heat-only environments?
Nope, the stainless steel casters with NP wheels are made for moist high heat like steam autoclaves—for dry high heat applications, pick our “TP” High Temp Phenolic high temperature wheels instead.
How do I protect the NP High Temp Glass-Filled Nylon Wheel in the Stainless Steel Stem Caster Model SS-K3A in moist high heat settings?
Keep the NP High Temp Glass-Filled Nylon Wheel in the Model SS-K3A high temperature caster shielded from direct heat sources, like flames or radiant heat, to prevent damage and maintain performance in moist high heat settings.
Do the NP high temperature wheels in the stainless swivel caster leave marks on floors in moist high heat environments?
No, the glass-filled nylon build of the NP high temperature wheels in the stainless swivel caster is non-marking, ideal for protecting smooth floors in steam autoclaves or food processing spots with moist high heat.
Why are the stainless steel industrial casters with NP High Temp Glass-Filled Nylon Wheels cost-effective for moist high heat use?
The stainless steel industrial casters with NP High Temp Glass-Filled Nylon Wheels deliver durable, high temperature performance in moist heat at a lower cost than other high temperature casters, making them a smart choice for wet high heat applications without a big price tag.
Can the NP High Temp Glass-Filled Nylon Wheel in the stainless high temp caster go above 525°F in moist high heat settings?
No, running the NP High Temp Glass-Filled Nylon Wheel in the stainless high temp caster above 475°F for more than 30 minutes or past 525°F will cut its service life—always let it cool down after high heat exposure.
