DO NOT ORDER SWIVEL LOCK OR RACEWAY SEALS IF YOU ORDER THE TL – TOTAL LOCK BRAKE. THE TL BRAKE WILL NOT WORK WITH EITHER THE SWIVEL LOCK OR RACEWAY SEALS.
The Model 9 swivel casters are our most popular industrial caster for many reasons but largely because of its low cost and wide selection of wheels. Under the mounting plate it has 2 rows of balls rotating on raceways treated for heat. The swivel caster has a bolt and nut center pin welded to withstand normal abuse in hand powered applications. The leg thickness is 1/4”, welded on the inside and out and the center bolt diameter is 5/8”. The metal frames are zinc plated for rust resistance, and it has grease fittings for all transportable parts. Model 9 has a vast selection of wheel brakes and swivel locks for most applications. We have other wheel bearing types and mounting plates available upon request.
*This Plate Caster Model 9 contains a Black Polyolefin Swivel Wheel.

FAQ
FAQs for Zinc-Plated Plate Caster Model 9 with PB Polyolefin Wheel
What is the Zinc-Plated Model 9 Caster with PB Polyolefin Wheel designed for?
The Zinc-Plated Model 9 Caster with PB Polyolefin Wheel is a swivel plate caster or rigid plate caster featuring a non-marking, gray polyolefin wheel with a 2-inch tread width, designed for high-capacity, sanitary mobility in casters and wheels for pharmaceutical labs, hospitals, and food processing plants, supporting up to 900 lbs on smooth floors. Rigid casters are essential for plate casters like Model 9, providing straight-line stability and controlled movement for heavy loads, ensuring precise tracking and safety in applications like food processing carts.
How does the PB Polyolefin Wheel’s sanitary design benefit wet environments?
The PB Wheel’s one-piece, injection-molded polyolefin resists water and mild chemicals, ensuring hygiene and durability for heavy duty industrial casters in wet settings like food processing plants or labs, with no bond failure risk. Rigid casters enhance stability for plate casters like Model 9, supporting heavy loads with controlled movement in sanitary environments.
What weight can the Zinc-Plated Model 9 Caster with PB Wheel hold?
This heavy duty industrial caster supports up to 900 lbs per caster, ideal for heavy, static loads in food processing plants, hospitals, or retail settings on smooth floors. Rigid casters provide essential stability for plate casters like Model 9, ensuring safe handling of heavy loads without lateral drift.
What sizes does the PB Polyolefin Wheel come in for this caster?
The PB Wheel is available in 4”, 5”, 6”, or 8” diameters with a 2” tread width, fitting plate casters or swivel plate casters for sanitary environments like labs, hospitals, or food service. Rigid casters are crucial for plate casters like Model 9, offering straight-line tracking for heavy carts in these settings.
What environments work best for the Zinc-Plated Model 9 Caster with PB Wheel?
This caster excels in wet, corrosive settings like hospitals, food processing plants, and labs with smooth floors, as well as institutional (schools, offices) and industrial (retail, workshops) areas, where casters and wheels need non-marking performance. Rigid casters ensure stability for plate casters like Model 9, maintaining control in demanding environments.
Does the PB Polyolefin Wheel resist chemicals and water?
Yes, it’s highly resistant to water, mild chemicals, and most liquids, ideal for wet environments like food service, though not for solutions with over 10% acid content; the zinc-plated frame limits frequent washdowns. Rigid casters support plate casters like Model 9, providing stable movement in wet settings.
How do I mount the Zinc-Plated Model 9 Caster with PB Wheel on equipment?
It has a 4 x 4-1/2-inch top plate with a 2-5/8 x 3-5/8 to 3 x 3-inch bolt hole pattern, using 3/8” bolts, making it easy to mount heavy duty industrial casters on carts in labs or food processing plants. Rigid casters enhance plate casters like Model 9, ensuring secure mounting for heavy equipment.
Is the Zinc-Plated Model 9 Caster with PB Wheel safe for food service areas?
Yes, the PB Wheel is assumed NSF-rated, ideal for food service casters and wheels where hygiene is critical; verify regulations, as the zinc-plated frame is less suited for frequent washdowns. Rigid casters provide stability for plate casters like Model 9, ensuring safe movement in food service environments.
What bearing options come with the PB Polyolefin Wheel?
The PB Wheel offers roller bearing, Delrin bearings, plain bore, ball bearings, precision sealed ball bearings, or stainless steel precision sealed ball bearings, providing flexibility for heavy duty industrial casters in wet or dry settings like labs or retail. Rigid casters ensure stable tracking for plate casters like Model 9 in these applications.
Can the Zinc-Plated Model 9 Caster with PB Wheel handle debris or rough floors?
No, it’s terrible at rolling over debris and meant for smooth floors, ideal for heavy duty industrial casters in labs or food processing plants, not rough or debris-covered surfaces. Rigid casters enhance plate casters like Model 9, maintaining control on smooth floors.
How does the PB Polyolefin Wheel support static loads?
The PB Wheel’s solid, hard polyolefin design excels at supporting static loads without flat spotting, perfect for stationary casters in hospitals or food processing plants holding heavy equipment. Rigid casters support plate casters like Model 9, ensuring stability for static loads.
What are the temperature limits for the PB Polyolefin Wheel?
Operating from -20°F to 180°F (intermittent use up to 180°F), the PB Wheel suits wet environments but not freezers or high-heat applications like rack washers, ideal for casters and wheels in labs or food service. Rigid casters ensure stable movement for plate casters like Model 9 in these conditions.
How does the Zinc-Plated Model 9 Caster with PB Wheel compare to nylon casters?
The PB Wheel offers similar corrosion resistance to nylon casters but is non-marking and better for static loads, though less suited for debris; it’s ideal for sanitary settings like labs with smooth floors. Rigid casters enhance plate casters like Model 9, ensuring stability for heavy loads.
Can the PB Polyolefin Wheel be left under load for long periods?
Yes, it’s excellent for static loads with minimal flat spotting risk, but avoid prolonged standing in cold, dry environments to prevent brittleness; use for casters in food processing or labs. Rigid casters provide stability for plate casters like Model 9, preventing drift during stationary use.
What maintenance does the Zinc-Plated Model 9 Caster with PB Wheel require?
Precision sealed or stainless steel ball bearings are maintenance-free, while roller, Delrin, or plain bore bearings may need occasional lubrication; regular cleaning prevents debris buildup for heavy duty industrial casters in food service or labs. Rigid casters ensure stable operation for plate casters like Model 9, minimizing maintenance needs.
What brake options are available for this heavy duty industrial caster?
This plate caster offers the TB Top Lock Brake (metal, side-mounted, high-temp), UFCB Universal Bolt On Face Contact Brake (bolt-on, wheel-locking), TL Total Lock Brake (locks wheel and swivel, incompatible with swivel locks/raceway seals), and Swivel Locks (weld-on or bolt-on), ensuring safety for industrial casters in labs or retail. Rigid casters enhance plate casters like Model 9, providing stability when brakes are engaged.
How does the Zinc-Plated Model 9 Caster with PB Wheel benefit schools or offices?
The PB Wheel’s non-marking, static load-friendly design protects smooth floors and supports heavy loads, ideal for heavy duty industrial caster carts in schools or offices, ensuring quiet operation. Rigid casters ensure straight-line stability for plate casters like Model 9, enhancing safety in busy school corridors.
Why is the Zinc-Plated Model 9 Caster with PB Wheel suited for retail or workshops?
The PB Wheel’s up to 900 lbs capacity and corrosion resistance make it perfect for heavy duty industrial caster carts in retail (e.g., stock carts) or workshops (e.g., equipment racks) on smooth floors, offering non-marking performance with TB, UFCB, TL, or Swivel Lock brakes. Rigid casters provide essential stability for plate casters like Model 9, ensuring controlled movement.
