Impact Resistant Caster Extra Heavy Duty Caster 500kg 200mm Iron Core PU Caster 8" Shock Absorbing Casters Urbine & Generator-component Carts

K01 Series — 8" (200 mm / 8 inch) Heavy Duty Caster

Iron Core Polyurethane (PU) · Shore 95A · Galvanized 5.5 mm Bracket · No Spring (Rigid)

1. Product Overview

The K01 8" (200 mm / 8 inch) is a heavy-duty industrial caster built around an iron-core polyurethane (PU) wheel in Shore 95A. With a load capacity of 500 kg per caster (2000 kg on a standard 4-caster system), it is the the largest and highest-capacity K01 size — built for the heaviest static and slow-moving loads in energy, steel and infrastructure. The 50 mm wide tread, 5.5 mm galvanized steel bracket and precision ball bearing deliver stable, maintenance-free rolling for everyday heavy material handling.

3. Features & Advantages

·         Iron Core + PU Tread: the steel core carries the load while the polyurethane tread rolls smoothly, resists wear and protects the floor.

·         Shore 95A Polyurethane: high hardness for excellent load support and abrasion resistance, with good oil- and chemical-resistance.

·         5.5 mm Galvanized Bracket: thick, cold-pressed steel bracket with zinc plating for strength and corrosion resistance in demanding environments.

·         Precision Ball Bearing: low-friction rolling for easy push/pull and long service life under continuous use.

·         50 mm Wide Tread: wider contact patch than standard 40 mm wheels for better stability and reduced ground pressure.

·         Rigid, No-Spring Design: no moving suspension parts — simple, rugged and reliable for static or slow-moving loads.

4. Why the Iron Core Wheel Matters

The iron (steel) core is the structural backbone of the wheel. It supports the heavy load without deforming, transfers weight evenly to the bearings and bracket, and keeps the wheel running true under continuous rolling.

Important Applications & Load Limits

·         Best for: steel plants, foundries, mould & die shops, transformer/substation handling, heavy machinery bases and other high-load, low-speed environments.

·         Not recommended for: extremely wet, marine or chemical-washdown environments (choose stainless/anti-corrosion option); shock-sensitive precision loads requiring spring suspension (choose our A04 / A05 dual-spring series); delicate polished floors where a softer or aluminium-core wheel is preferred.

This caster is a rigid, non-spring type. It is designed for stable support and straight rolling — if your route involves expansion joints, uneven floors or frequent impact, consider our shock-absorbing spring-suspension models.
