Product Description

8" 200mm Iron Core PU Flat Tread Heavy Duty Caster

8 Inch Heavy Duty Iron Core Cast Polyurethane (PU) Caster - 200mm Rigid, Swivel & Brake

Product Overview

The 8 Inch (200mm) Heavy Duty Iron Core Cast Polyurethane (PU) Caster is built for the heaviest industrial transport tasks. Featuring a 50mm wide flat/plain tread and a rigid 5.5mm thick bracket, this caster delivers maximum load-bearing performance without spring suspension. Available in Fixed (Rigid), Swivel, and Brake configurations, it is the ideal choice for stable, heavy-duty material handling on flat surfaces.

Model Series: B01-R/S/H-1PU-850
Wheel Diameter: 8" / 200mm
Tread Width: 50mm (Flat/Plain Tread)
Load Capacity: 450kg per caster
Bearing: 6203/6202 Ball Bearing
Installation Height: 240mm
Top Plate: 115*100mm | Hole Spacing: 82*72mm | Hole: Ø13mm
Bracket Thickness: 5.5mm (Base & Fork)
Material: Iron Core + Cast Polyurethane (PU), Shore A 95-98
Options: Fixed / Swivel / Brake

Features & Advantages

High Load Capacity: Supports up to 450kg per wheel, perfect for the heaviest industrial carts and machinery.
Durable Iron Core: Prevents wheel deformation under sustained heavy loads.
Cast PU Tread (Shore A 95-98): Excellent wear resistance, floor-protective, quieter than PP, good traction.
50mm Flat Tread: Provides maximum ground contact for superior stability and straight-line tracking.
Rigid Structure: 5.5mm thick bracket ensures long service life with no flexing under weight.
Smooth Operation: Equipped with 6203/6202 ball bearings for low-friction swiveling and pushing.
No Spring Design: A rigid, non-shock-absorbing structure that keeps equipment height stable and predictable.

Application Scenarios

The 8" rigid iron core PU caster is best suited for environments where stability and heavy load distribution are prioritized over shock absorption:

Heavy Industrial Carts & Large Warehouse Dollies: Ideal for moving heavy molds, dies, and bulk materials.
Die/Mold Handling Trolleys: Provides a stable base for transporting heavy tooling.
Bulk Material Transporters: Used for large containers and bins in manufacturing plants.
Heavy Equipment Stands: Supports large machinery bases on flat floors.
Staging/Moving Fixtures: Offers secure positioning for heavy assembly platforms.

Note: Not suitable for CNC routers, scissor lifts, or uneven outdoor terrain where spring suspension is required.

Material & Build Advantages

Cast Polyurethane (PU) Tread: Cast PU offers superior mechanical properties compared to molded PP -- higher tear strength, excellent abrasion resistance, and non-marking performance on epoxy and concrete floors. Shore A 95-98 provides the ideal balance of hardness and elasticity for heavy loads.
Iron Core Construction: Provides the structural integrity needed to handle 400kg without wheel distortion.
Galvanized Finish: The 5.5mm bracket features a protective coating to resist corrosion in industrial environments.
Standardized Mounting: The universal 115*100mm top plate allows for easy integration into existing equipment designs.

Aluminium Core vs. Iron (Steel) Core Comparison

Feature	Aluminium Core	Iron (Steel) Core
Weight	Lighter, reduces overall trolley weight	Heavier, adds stability to heavy loads
Corrosion Resistance	Excellent, naturally rust-resistant	Good (with coating), but prone to rust if scratched
Load Capacity	High, but can deform under extreme static load	Exceptional for heavy, sustained static loads
Cost	Higher	More cost-effective for heavy-duty use
Best For	Medical, food-grade, or lightweight aluminum trolleys	Heavy industrial machinery, warehouse carts, and rugged use

Flat Tread vs Arc Tread Design

Understanding the tread design is crucial for selecting the right caster:

Flat / Plain Tread (This Product): Features a full 50mm width of contact with the floor. It provides maximum stability, higher load distribution, and better straight-line tracking. It is designed for heavy-duty, flat-floor industrial use where equipment must remain steady.
Arc / Curved Korean-Style Tread: Has a rounded crown. This reduces the contact patch, making it easier to pivot and turn (less scrub resistance). It is typically used for lighter-duty trolleys where maneuverability is more important than load stability.

The Biggest Difference: Flat tread = Stability & Heavy Load. Arc tread = Maneuverability & Easy Turning. This 6" caster is a rigid, anti-impact structural wheel with no shock absorption or spring suspension, built for strength, not cushioning.
