Description
8″ Gray Soft Rubber Wheel. Shown in photo with 5″ x 2″ wheel.
Stainless Steel 316 Series Model 9.
The SS316-9 Industrial Caster Model 9 with RF Soft Gray Rubber Wheel is built for highly corrosive environments where durability and hygiene are critical. Made from 1/2″ thick stamped 316 stainless steel with molybdenum (2-3%) and higher nickel content, it offers superior resistance to chlorides, acids, and harsh cleaning agents compared to 304 stainless steel, ideal for marine, chemical, and food processing settings. Its swivel design features a double ball raceway held by a 5/8″ stainless steel nut and bolt kingpin (welded for durability), lubrication fittings in the swivel bearing and 1/2″ stainless steel axle, and two brake options (swivel lock and total lock), while the rigid model ensures fixed-direction stability, both supporting up to 300 lbs per caster with a mounting plate of 4″ x 4-1/2″ (bolt hole pattern 2-5/8″ x 3-5/8″ to 3″ x 3″).
This caster uses a 8″ x 2″ RF Soft Gray Rubber wheel, injection-molded with a non-marking thermoplastic rubber tire bonded to a polyolefin center, operating from -20°F to 160°F with a Shore A 90-95 durometer. The wheel features default Delrin bearings for chemical resistance, reducing noise, absorbing shock, and protecting floors while rolling over small debris, and resists many chemicals and solvents, though it’s not suited for shock, overloading, abuse, obstructions, poor floors, or prolonged standing loads, which can cause flat spots. The wheel provides a softer ride than polyurethane, making it ideal for smooth floors in sanitary applications.
The 316 Stainless Steel Model 9 is used in marine applications, chemical plants, and food processing facilities needing corrosion-resistant, sanitary designs, meeting NSF and ROHS standards for hygiene with an electrolytic finish for smoothness. It’s a step up from the 316 Stainless Steel Model 3, offering higher capacity and durability for hand-powered applications, but for mechanically powered or abusive uses, the Model G15 (up to 1500 lbs) is recommended. Available online at Caster City with a fast lead time, this caster provides reliable mobility for light-duty manual use in the harshest conditions; contact Caster City at 800-501-3808 for ordering assistance.
