FAQ

What is the load capacity of the Model 2-50 heavy-duty dual wheel industrial kingpinless caster with Ultra High Capacity Polymer wheels?

The Model 2-50 caster, using two 12×3 Ultra High Capacity Polymer (NX) wheels, is rated for up to 7,000 lbs per caster under ideal conditions (manual operation at speeds up to 3 mph). Contact Caster City at 800-501-3808 for reduced ratings in powered or abusive conditions.

What are the mounting plate specifications for the Model 2-50 heavy-duty dual wheel industrial kingpinless caster?

The caster features a top plate size of 5 1/4″ x 7 1/4″, with bolt hole spacing of 3 3/8″ x 5 1/4″ slotted to 4 1/8″ x 6 1/8″, and accepts 1/2″ mounting bolts, ensuring secure installation for heavy-duty applications.

What wheel size is available for the Model 2-50 heavy-duty dual wheel industrial kingpinless caster with Ultra High Capacity Polymer wheels?

The Model 2-50 uses two Ultra High Capacity Polymer (NX) wheels per caster, each 12-inch diameter with a 3-inch width, featuring 4 precision sealed ball bearings for balanced load distribution.

What makes the Ultra High Capacity Polymer wheels on the Model 2-50 caster effective for heavy loads?

The NX wheels are compression-molded nylon with an 80 Shore D durometer and flat tread, supporting heavy loads without damaging floors like metal wheels. They resist chemicals, oils, and acids, and won’t flatten under static loads, unlike polyurethane wheels.

What industries are best suited for the Model 2-50 heavy-duty dual wheel industrial kingpinless caster with Ultra High Capacity Polymer wheels?

Ideal for aerospace (component transport), heavy manufacturing (machinery movement), automotive (tow-line systems), and warehouses, these casters protect smooth indoor floors while handling substantial loads with non-marking performance.

What is the difference between swivel and rigid Model 2-50 casters with Ultra High Capacity Polymer wheels?

Swivel casters offer 360-degree rotation for maneuverability in tight spaces, while rigid casters provide stability for straight-line movement in tow-lines or heavy equipment transport.

Are the Ultra High Capacity Polymer wheels on the Model 2-50 caster worth the higher cost?

Yes, the NX wheels prevent floor damage and flat spots, reducing maintenance costs. They’re a cost-effective alternative to metal wheels for heavy-duty indoor applications requiring floor protection.

What bearing options are available for the Model 2-50 heavy-duty dual wheel industrial kingpinless caster with Ultra High Capacity Polymer wheels?

Each 12×3 NX wheel features 4 precision sealed ball bearings for smooth, maintenance-free operation. Roller or stainless steel bearing options may be available; contact Caster City for details.

Can the Model 2-50 caster with Ultra High Capacity Polymer wheels be customized?

Yes, options include swivel locks for straight-line travel (swivel models), toe guards, and face contact brakes, which lock both wheels but are non-returnable. Contact Caster City at sales@castercity.com for customization details.

What is the benefit of the kingpinless design in the Model 2-50 heavy-duty dual wheel industrial kingpinless caster with Ultra High Capacity Polymer wheels?

The kingpinless design, with hot-forged steel and precision-machined load and thrust bearings, eliminates the center pin, enhancing durability and load distribution for high-capacity tasks like manufacturing or aerospace transport.

What are the operating conditions for the Model 2-50 caster with Ultra High Capacity Polymer wheels?

Rated for manual operation at speeds up to 3 mph on smooth surfaces, with a temperature range of -20°F to 250°F. Avoid rough terrain or heavy impacts, as NX wheels are not designed for sustained shocks. Consult Caster City for powered equipment ratings.

Where can I purchase the Model 2-50 heavy-duty dual wheel industrial kingpinless caster with Ultra High Capacity Polymer wheels?

Order from www.castercity.com, call 800-501-3808 (Monday–Friday, 7:45 AM to Noon PST & 1:00 PM to 2:30 PM PST), or email sales@castercity.com.

What precautions should I take when installing the Model 2-50 heavy-duty dual wheel industrial kingpinless caster with Ultra High Capacity Polymer wheels?

Avoid dragging wheels sideways, exceeding capacity, or improper mounting (fewer than 4 bolts). Use 1/2″ bolts with the 5 1/4″ x 7 1/4″ plate, ensure rigid casters are parallel, and swivel casters are floor-parallel. Use on smooth surfaces, as NX wheels are not suited for heavy impacts.

Can the Model 2-50 caster with Ultra High Capacity Polymer wheels handle high-traffic industrial environments?

Yes, the NX wheels’ non-marking nylon, 80 Shore D durometer, and sealed bearings ensure smooth, durable operation in high-traffic areas like warehouses or automotive plants, protecting floors from damage.

Why are the Model 2-50 caster’s Ultra High Capacity Polymer wheels ideal for heavy static loads?

The compression-molded NX wheels won’t develop flat spots under heavy static loads, unlike polyurethane, making them perfect for prolonged standing applications in manufacturing or aerospace without floor damage.

Why choose Ultra High Capacity Polymer wheels over metal wheels for the Model 2-50 caster?

NX wheels support heavy loads like metal wheels but are non-marking, preventing floor damage in indoor settings. They resist chemicals and won’t flatten, though they’re not suited for sustaining heavy impacts.
