Why Choose Solid Elastomer Casters?

• Single-material tread: One-piece construction removes the tread-to-core bond that can fail on bonded wheels.
• Floor protection with quieter rolling: The elastic tread absorbs impact and helps protect concrete, tile, and coated floors from the harsher contact of hard wheels.
• High load capacity: Options range from 1,050 lbs per caster to 3,400 lbs per caster.
• Low rolling resistance: The tread compound helps keep push force manageable as loads increase.
• Rigid and swivel configurations: Matching options make it easier to set up carts for straight tracking, turning, or both.
• Fast shipping: In-stock solid elastomer casters ship within 24 hours and are backed by a 30-day return policy.

Shop Solid Elastomer Caster Wheels by Size

Use wheel diameter, capacity, overall height, and swivel design to narrow your choice.

The 4" through 8" models use a pressed-steel, zinc-plated fork, a bolted wheel axle, and a 4" x 4-1/2" top plate with a 2-5/8" x 3-5/8" bolt pattern. The 10" model uses a larger 6-1/4" x 7-1/4" mounting plate with a 4-1/2" x 6" bolt pattern.

You can also shop by 4" wheels, 5" wheels, 6" wheels, 8" casters, or 10" wheels.

What Load Capacity Do You Need?

Start with the cart's fully loaded weight, including the cart itself and everything it will carry. Divide that weight by the number of casters supporting the load, then allow a safety margin for uneven loading and real-world operating conditions.

Atlanta Caster's solid elastomer line starts at 1,050 lbs per caster on the 4" and 5" models, reaches 1,100 lbs on the 6" size and 1,200 lbs on the 8" size, then rises to 3,400 lbs on the 10" kingpinless swivel.

If your application falls within the 500–2,000 lb range, compare our medium-duty casters. For higher-load applications, see our heavy-duty casters.

Solid Elastomer vs. Rubber vs. Polyurethane: Which Fits Your Cart?

Rubber, polyurethane, and solid elastomer caster wheels can all protect floors and roll more quietly than metal wheels, but they suit different operating conditions.

Rubber caster wheels are a strong choice when vibration absorption on rough or uneven floors is most important. Polyurethane caster wheels work well on smooth concrete and are commonly selected for applications with oil and chemical exposure.

Solid elastomer sits between those choices for buyers who need heavier load capacity, floor protection, quiet rolling, and a single-piece tread that avoids bonded-tread separation during repetitive push-pull duty. That makes industrial elastomer casters especially useful on tow lines, freight-terminal carts, and automotive assembly equipment.

For a broader comparison of materials, see our full caster wheel material guide.

How Many Casters Does Your Cart Need?

Many carts use four casters, often two rigid and two swivel. The rigid pair helps the cart track straight, while the swivel pair allows steering.

Larger platforms, tow-line trains, and carts with unevenly distributed loads may need five or six casters to keep each wheel's load within its rated capacity. If the application is unusual, our Certified Caster Specialists can review the cart weight, wheel arrangement, mounting pattern, and operating conditions with you.

What Are Solid Elastomer Casters Used For?

Solid elastomer casters are a practical fit for demanding applications where carts move repeatedly under load.

• Automotive assembly and tow lines: Repetitive towing and in-plant parts movement benefit from the chip- and crack-resistant tread. See our automotive solutions.
• Manufacturing and freight terminals: High-capacity carts carrying raw materials or finished goods benefit from low rolling resistance and durable wheel construction. Visit our manufacturing solutions.
• Warehouse and distribution: The 6" and 8" sizes are compatible with many platform trucks and material-handling carts. See warehouse and distribution solutions.
• Movies and entertainment: Touring equipment and road cases face constant loading, unloading, and movement across venue floors. See our movies and entertainment solutions.
• Industrial replacement: Solid elastomer can replace worn wheels where floor protection, quieter movement, and heavier repetitive duty are priorities.

Frequently Asked Questions

1. What Is a Solid Elastomer Caster Wheel?

A solid elastomer caster uses a wheel molded from a single block of elastomer material instead of a tread bonded to a separate core. That one-piece construction gives it a thick, elastic tread and helps resist chipping, cracking, flat-spotting, and tread separation under heavy use.

2. What Load Capacity Do Solid Elastomer Casters Carry?

Atlanta Caster's solid elastomer casters range from 1,050 lbs per caster on the 4" and 5" sizes to 3,400 lbs per caster on the 10" kingpinless swivel. Calculate capacity per caster and include a margin for uneven loading.

3. Are Solid Elastomer Casters Good for Heavy Push-Pull Carts?

Yes. Their one-piece tread is well-suited to continuous push-pull applications because there is no separate tread layer that can detach from the wheel core. They are commonly used on tow lines, assembly carts, and other repetitive-duty equipment.

4. Do Solid Elastomer Casters Protect Floors?

The elastic tread absorbs more impact than a hard metal wheel and is designed to roll quietly while helping protect concrete, tile, and coated floors. If your floor has strict non-marking requirements, contact Atlanta Caster to confirm the right wheel for that surface.

5. What Is the Difference Between Solid Elastomer and Rubber Caster Wheels?

Rubber wheels typically provide greater vibration absorption on rough surfaces. Solid elastomer wheels carry heavier loads in this line and use a one-piece tread that resists chipping, flat-spotting, and tread separation during repetitive heavy use.

6. What Is the Difference Between Kingpin and Kingpinless Swivel Casters?

Kingpin swivel casters use a center bolt to hold the swivel section together. Kingpinless designs use a ball-bearing raceway instead and are typically chosen for higher-capacity, harder-duty applications. Atlanta Caster's 4"–8" solid elastomer swivel casters use kingpin construction, while the 10" swivel uses a kingpinless design rated to 3,400 lbs.

7. How Fast Do Solid Elastomer Casters Ship?

In-stock solid elastomer casters ship within 24 hours from Atlanta Caster's Tucker, GA distribution center. Delivery is typically 7–10 days, and orders include a 30-day return policy. If you need help confirming size, load capacity, or mounting requirements, contact our Certified Caster Specialists before ordering.
