FAQ
What is the Heavy Duty Kingpinless Industrial Plate Caster Stainless Steel Model G15?
The Heavy Duty Kingpinless Industrial Plate Caster Stainless Steel Model G15 is an industrial plate caster with plate mount, handling up to 1,500 pounds per caster. Made from 304 stainless steel with 1/4″ thick legs welded inside and out, it features a kingpinless swivel construction with precision machined load and thrust bearings, a 1/2” diameter hollow bolt axle with lock nut, and external zinc-plated metal parts. It’s built for wet and corrosive spots like food processing, pharma plants, and marine use, with a tougher design than lighter models.
What environments and applications work best for the Stainless Steel Caster Model G15?
This heavy duty kingpinless stainless steel caster is made for wet and corrosive environments, like food processing plants, pharmaceutical manufacturing, marine settings, hospitals, labs, water treatment facilities, and automotive or aerospace plants. It handles tasks such as heavy ingredient carts, cleanroom transport, dock cargo carts, mobile processing equipment, sterile movers, container transport in chemical plants (with acids below 10%), fish processing gear, heavy medical equipment like MRI machines, hazardous material carts, and chemical feed systems. The 304 stainless steel frame resists rust and chemicals, perfect for washdowns.
What is the load capacity of the Stainless Steel Caster Model G15?
The Model G15 supports up to 1500 lbs per caster, but it depends on the wheel you pick. It’s rated for manual or powered use on smooth floors, no steep inclines over 3 degrees, and speeds under 3 mph.
What bearing options are available for the Stainless Steel Caster Model G15 with PB Polyolefin Wheel?
For the Model G15 stainless caster with PB Polyolefin Wheel, you can choose stainless steel roller bearings (SSR), stainless steel precision sealed ball bearings (SSPSBB), sealed precision bearings (SPS), precision sealed ball bearings (PS), roller bearings (R), ball bearings (B), bronze (BRNZ), Delrin bearings (D), or plain bore (P). These let you customize for wet environments.
Why choose the PB Polyolefin Wheel for the Stainless Steel Caster Model G15?
The 304 stainless steel frame resists rust and chemicals, making it great for wet spots with frequent cleaning. The polyolefin wheel handles water, mild acids (below 10%), grease, and oils, so it fits labs and food service well, but skip it for high-acid stuff.
What brake options does the Stainless Steel Caster Model G15 have?
The SS-G15 stainless swivel caster has braking options including wheel brakes (pedal on side of wheel, locks only the wheel from rolling—not available on V-Groove wheels or swivel with long lead), and swivel lock (converts swivel to rigid for straight lines or ramps, locks only swivel, not the wheel). Brakes aren’t designed to hold on inclines. It also offers SUFCB – Stainless Steel Bolt On Universal Face Contact Brake (face contact brake).
How do I maintain the Stainless Steel Caster Model G15?
Clean off debris after washdowns. Avoid leaving heavy loads sitting long, shocks, or harsh hits to keep it performing in wet spots.
Where can I buy the Stainless Steel Caster Model G15 with PB Polyolefin Wheel?
Get the Model G15 stainless caster from Caster City’s website at www.castercity.com or call 800-501-3808. Lead time is usually 2 days for fast delivery.
How does the Heavy Duty Kingpinless Industrial Plate Caster Stainless Steel Model G15 compare to Model 3 or 9?
The Model G15 heavy duty kingpinless stainless steel caster is a step up from our Stainless Steel Caster Model 9 plate casters, supporting up to 1500 lbs per caster depending on the wheel. It has a kingpinless design with precision machined load and thrust bearings, and is made of 304 stainless steel with zinc-plated external parts for tougher abuse in manual or powered setups. Model 9 tops at 1200 lbs with a welded kingpin, so go G15 for abrasive or powered jobs where some wheels rate higher due to the rugged build. Call 800-501-3808 for help.
What’s the difference between swivel and rigid versions of the Stainless Steel Caster Model G15?
Swivel versions of this stainless swivel caster have full rotation for maneuvering, with a kingpinless design, precision bearings, and 1/4″ thick welded legs. Rigid casters don’t swivel, made from 304 stamped stainless steel for the plate and legs, with a 1/2″ axle bolt. Pick rigid when price matters or for straight-line travel over long distances or ramps—install them opposite the push handle for better steering. Both are great for corrosive washdowns like food processing.
What wheel options are available for the Stainless Steel Caster Model G15?
This caster has a broad selection of 2″ wide wheels, including polyolefin (like PB black or high capacity), gray soft rubber flat, all polyurethane (blue, gray heavy duty, blue/black, maroon/gray), poly on glass-filled nylon, nylon (white or black), phenolic, high temp glass filled nylon, high temp phenolic fiberglass, solid stainless (flat or V-groove), ultra high capacity polymer, and crown tread ergonomic polyurethane on aluminum (orange) or crown polyurethane on aluminum. Diameters from 4″ to 8″.
Is the Stainless Steel Caster Model G15 suitable for total locking?
Yes, the Model G15 total lock stainless caster offers wheel brake options that lock the wheel, but it’s not for holding on inclines—great for securing in wet or corrosive setups. Check swivel lock for rigid conversion.
What is the swivel radius and overall height for the Stainless Steel Caster Model G15?
The swivel radius is 3 5/8″ for 4″ wheels, 4 1/4″ for 5″, 4 1/2″ for 6″, and 6 1/2″ for 8″. Overall height is 5 5/8″ for 4″ wheels, 6 1/2″ for 5″, 7 1/2″ for 6″, and 9 1/2″ for 8″.
What construction details make the Heavy Duty Kingpinless Industrial Plate Caster Stainless Steel Model G15 durable?
The swivel has a kingpinless construction with precision machined load and thrust bearings, 1/4″ thick stainless steel legs welded inside and out, a 1/2” diameter hollow bolt axle with lock nut, and zinc-plated external parts for added toughness.
Can the Stainless Steel Caster Model G15 handle high temperatures?
Yeah, it can with the right wheels like high temp glass filled nylon or high temp phenolic fiberglass, but check the max capacity—it drops if you’re running over 40 minutes at peak temps. Consult if needed.
What installation tips are there for the Stainless Steel Caster Model G15?
Make sure rigid casters are parallel to each other, swivels are parallel to the floor, and use at least 4 bolts on the mounting plate. Don’t distort the swivel bearing during install, like from bad welding, and avoid dragging sideways or dropping loads hard.
What’s the weight of the Stainless Steel Caster Model G15 swivel version?
It weighs around 5 to 19 lbs depending on the wheel—most are 5-8 lbs, up to 19 lbs for heavier options like 6” solid stainless V-groove. Rigid versions are similar but slightly lighter.
What is 304 stainless steel in the Stainless Steel Caster Model G15?
304 stainless steel is the most common stainless out there, an austenitic alloy with about 18% chromium and 8% nickel—often called 18/8 stainless. It gives excellent corrosion resistance against rust and chemicals, which is why it’s used for the frame in the Model G15, making it perfect for wet and corrosive spots like food processing or pharma plants.
What are the overall heights for the Stainless Steel Caster Model G15 with different wheel diameters?
Overall height of Stainless Steel Model G15 with 4 inch diameter wheel: 5-5/8″. With 5 inch wheel: 6-1/2″. With 6″ wheel: 7-1/2″. With 8 inch wheel: 9-1/2″.
What applications is this caster best for?
This stainless steel caster Model G15 is best for manually or powered moved setups, like carts or equipment that can handle some towing or abuse—it’s tougher than lighter models for rough handling on smooth floors. It’s built for wet, corrosive, or high-heat spots where you need rust resistance and easy washdowns, like food processing, pharma, or marine work.
