Description

Stainless Steel Rigid Caster Model 30 are the heaviest duty stainless steel rigid casters that we manufacture.  These Rigid casters have a taller overall height and a larger mounting plate than Stainless Steel Model G15 and accommodate 3” Wide Wheels.  It features superior performance on both manually moved and mechanically powered equipment. The Stainless Steel Model 30 rigid caster frames are constructed from 304 SS and given electrolytic polishing to a shining finish . There are grease fittings for the wheel bearings in the axle.  NSF and ROHS Compliant.

Rigid casters are usually attached to equipment at the opposite end of the cart from where the push handle and swivel casters are attached. This enables the person pushing the equipment to be able to control the direction of travel. It should also be stressed that Rigid casters have 2 legs perpendicular to the mount plate, therefore they can not move sideways. Equipment with 2 rigid casters and 2 swivel casters must be maneuvered into position.

10″ x 3″ Ultra High Capacity Polymer Wheel Precision Ball Bearings in wheel.  Nylon wheels are an excellent choice for supporting heavy loads without using a metal wheel since they can not develop a flat spot. Nylon is resistant to greases, oils, blood, acids, bases and more.  This industrial caster wheel comes in 3″ wide, and comes in diameters ranging from 6” to 10”.

Stainless Steel Rigid Caster Model 30 uses 3″ wide industrial caster wheels.

If you need this caster with a larger mounting plate fastening option, Caster City manufactures Stainless Steel Caster Model 50.

The Inner Workings of the Ultra High Capacity Polymer Caster Wheels

Ultra High Capacity Polymer Caster Wheels from Caster City are engineered to support heavy loads while protecting floors from the damage typically caused by metal wheels. Unlike polyurethane wheels, which can develop flat spots or delaminate under prolonged static loads, these non-marking black polymer wheels are compression molded and machined for superior durability and performance. Their straight-sided design maximizes load capacity, making them an ideal choice for indoor applications on smooth surfaces where floor preservation is critical. Available in 2”, 3”, and 4” widths and diameters ranging from 3” to 12”, these wheels are equipped with 2 to 4 precision sealed ball bearings (depending on size) for smooth operation and long service life. With a hardness of 80 Shore D and a temperature range of -20°F to 250°F, they resist corrosion, chemicals, and impacts, offering a robust alternative to steel wheels.

These wheels are designed for a wide range of heavy-duty applications across industries, including material handling, manufacturing, warehousing, aerospace, automotive, and more. Their flat tread face ensures stable load distribution, and the compression molding process eliminates the risk of flat spots, making them perfect for equipment like platform trucks, assembly line carts, or automated guided vehicles (AGVs) that remain stationary under heavy loads. Capable of withstanding shocks, chemicals, oils, and acids, these wheels are also suitable for harsh environments like chemical plants, food processing facilities, or marine applications. For high-temperature settings (up to 250°F) or specialized needs, such as stainless steel bearings or roller bearings, Caster City offers customizable options to meet your requirements.
