RWM’s S45 Stainless Steel Casters feature a cold forged top plate, yoke and button that improves swivel action and increases service life with sealed raceways. The stainless steel casters are made of 304 series stainless steel which is electropolished to further improve long term corrosion protection and resistance to microbial buildup. Stainless steel casters provide a dramatic increase in resistance to corrosion due to environmental or chemical factors.
The standard tight fitting raceway seals and polished stainless steel finish make this an ideal solution for messy food processing facilities, OEM equipment, cooking facilities, wash-down applications and medical facilities. These casters are available with side actuated tread locking brakes which provide superior locking over conventional side wheel brakes and are also offered in a total locking version which locks both the wheel and the swivel raceway from rotating at the same time.
Raceway Design | Cold forged top plate, yoke and button improves swivel action and increases service life. Heavy duty load and thrust bearings are ground and rotate on raceways. Top plate and legs are 1/4″ steel, legs formed for increased strength. All swivel sections are equipped with a lubrication fitting for field maintenance. RWM lubricates all swivel sections prior to shipment. Sealed swivel raceways are standard. |
Capacity | Up to 900 lbs. |
Kingpin | 5/8″ diameter rivet hydraulically compressed to increase strength of swivel section as compared to staking. |
Axle | 1/2″ diameter drilled axle with lubrication fitting provided on casters to improve ease of lubrication where required (not required for ball bearing). |
Mounting Plate Size | 4″ x 4-1/2″ x 1/4″ |
Bolt Hole Spacing | 2-5/8″ x 3-5/8″, slotted to 3″x 3 |
Mounting Bolt Diameter | 3/8 |
Raceway Seals | Standard |
RWM’s Stainless Steel Casters feature 304 stainless steel that is highly resistant to conditions that would normally corrode and rust regular zinc plated steel casters. Our Stainless Steel Casters are ideal for wet or damp conditions and harsh environments that may rust or corrode standard zinc casters. These casters are well suited for rugged duty and are designed for wash-down applications such as:
Food processing plants & service equipment | Stock and maintenance carts |
Large volume, high temperature bakery and food cooking facilities | Ingredient bins |
Bakery and bread racks | Institutional service carts and equipment |
Slaughter houses | Hatcheries |
Fisheries | Pharmaceutical plants and laboratories |
Seafood processing plants |
