Neoprene rubber wheels combine durability with superior chemical resistance, featuring precision-machined stainless steel ball bearings that ensure smooth operation even in wet or corrosive environments. The neoprene compound offers excellent resistance to oils, greases, and animal fats while providing a resilient cushioned ride that protects both the floor and transported goods. These wheels maintain their performance characteristics across a temperature range of 35°F to 159°F (with brief exposure capability up to 350°F), and their sleek crown tread design enhances maneuverability while reducing rolling resistance. The integration of stainless steel precision sealed ball bearings ensures maintenance-free operation and longevity, making these wheels an ideal choice for food processing facilities, pharmaceutical applications, and any environment where chemical resistance and reliable performance are essential.

FAQ

What is the Stainless Steel Caster Model 9?

The Stainless Steel Caster Model 9 is an industrial plate caster with plate mount, handling up to 1,200 pounds per caster. It has a top plate size of 4″ x 4 1/2″, bolt hole spacing from 2-5/8″ x 3-5/8″ to 3″ x 3″, and uses 3/8″ mounting bolts. Made from 1/2″ thick 304 stainless steel, it features a 5/8″ welded kingpin, 1/2″ stainless steel axle, lubrication fittings, and is built for wet and corrosive spots like food processing, pharma plants, and marine use.

What environments and applications work best for the Stainless Steel Caster Model 9?

This heavy duty 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, and meets NSF and ROHS standards.

What is the load capacity of the Stainless Steel Caster Model 9?

The Model 9 supports up to 1200 lbs per caster, but it depends on the wheel you pick. It’s rated for manual 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 9 with PB Polyolefin Wheel?

For the Model 9 stainless caster with PB Polyolefin Wheel, you can choose roller bearings (R), Delrin bearings (D), plain bore (P), ball bearings (BB), precision sealed ball bearings (PS), stainless precision sealed ball bearings (SPS), or stainless steel roller bearings (SSR). These let you customize for wet environments.

Why choose the PB Polyolefin Wheel for the Stainless Steel Caster Model 9?

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 9 have?

The SS-9 stainless swivel caster has three braking options: TB – Top Lock Brake (pedal on side of wheel), TL – Total Locking Brake (pedal behind wheel, locks swivel and wheel), and TKB – Plastic High Temp Top Lock Brake (pedal behind wheel). It also offers SL4 – Welded Stainless Steel Swivel Lock (turns swivel into rigid for straight lines or ramps) and RS – Raceway Seals to protect from harsh environments.

How do I maintain the Stainless Steel Caster Model 9?

Lubricate the swivel bearing and axle regularly with the fittings to keep it moving smooth, and 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 9 with PB Polyolefin Wheel?

Get the Model 9 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 Stainless Steel Caster Model 9 compare to Model 3 or G15?

The Model 9 heavy duty stainless steel caster is a step up from our Stainless Steel Caster Model 3 plate casters, supporting up to 1200 lbs per caster depending on the wheel. It has two rows of ball bearings for axial and thrust loads, a 5/8″ nut and bolt kingpin welded together for manual abuse, and is made of 1/2″ thick stamped 304 stainless steel. If your setup is abrasive or powered, check the G15 model—it handles up to 1500 lbs with the same wheels, and some wheels rate higher on it due to tougher build. Call 800-501-3808 for help.

What’s the difference between swivel and rigid versions of the Stainless Steel Caster Model 9?

Swivel versions of this stainless swivel caster have full rotation for maneuvering, with a cold-forged top plate, yoke base, welded legs, and 5/8″ kingpin. Rigid casters don’t swivel, made from 1/4″ thick 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 NSF and ROHS compliant, great for corrosive washdowns like food processing.

What wheel options are available for the Stainless Steel Caster Model 9?

This caster has a broad selection of 2″ wide wheels that are NSF and ROHS compliant, including polyolefin (like PB), gray soft rubber, neoprene, polyurethane varieties, nylon, phenolic, high-temp options, V-groove, water-resistant polyurethane, and solid stainless steel. Diameters from 4″ to 8″.

Is the Stainless Steel Caster Model 9 suitable for total locking?

Yes, the Model 9 total lock stainless caster offers a TL – Total Locking Brake option, with the pedal behind the wheel to lock both swivel and wheel rotation. It’s not for holding on inclines, but great for securing in wet or corrosive setups.

What is the swivel radius and overall height for the Stainless Steel Caster Model 9?

The swivel radius is 3 1/2″ to 6 1/4″ depending on the wheel size, and it goes up to 6 1/2″ or 7 1/2″ if you add the total lock brake. 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 Stainless Steel Caster Model 9 durable?

The swivel has a cold forged top plate and yoke base from 1/4″ stainless steel, with 1/4″ thick legs welded inside and out. It uses a 1/2” diameter hollow bolt axle with lock nut, and comes with grease fittings for both swivel and wheel bearings.

Can the Stainless Steel Caster Model 9 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 9?

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 9 swivel version?

It weighs 5 to 8 lbs for most setups, up to 12 lbs if you go with solid stainless steel wheels. Knock off 1 lb for the rigid version.

What is 304 stainless steel in the Stainless Steel Caster Model 9?

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 9, making it perfect for wet and corrosive spots like food processing or pharma plants. It’s also NSF and ROHS compliant for hygiene standards.

What are the overall heights for the Stainless Steel Caster Model 9 with different wheel diameters?

Overall height of Stainless Steel Model 9 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 9 is best for manually moved setups only, like carts or equipment that isn’t towed or abused—stick to pushing by hand on smooth floors, no powered movement or rough handling. 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.
