Reducing Maintenance Issues Through Better Wheel Selection

Most workshops don’t think twice about spec’ing motors, steel or bearings properly.

But wheels? Often an afterthought.

The problem is, if your wheels or castors are under-specced, failing, or just wrong for the job, your equipment is basically a Ferrari on bald tyres. Looks great. Performs terribly.

And in a manufacturing environment, that quickly turns into downtime, frustration and unnecessary cost.

Why this matters more than people think

Across New Zealand manufacturing sites, mobile equipment is everywhere. Carts, jigs, workstations, trolleys. All moving, all day.

When the wheels aren’t right, you’ll start to see:

• Flat spotting

• Bearings failing early

• Equipment that’s hard (or unsafe) to move

• Operators avoiding certain trolleys altogether

• Floors getting damaged

None of this usually happens overnight. It creeps in, then suddenly maintenance teams are replacing the same wheels again and again.

The real impact (it’s not just maintenance)

When equipment doesn’t move properly:

• Jobs take longer

• Staff work harder than they should

• Workflow slows down

• Productivity drops

And if you’re supplying customers on tight timelines, small inefficiencies start becoming bigger problems.

Where it usually goes wrong

In most cases, it’s not the wheel failing. It’s the original specification.

Common issues:

• Load ratings underestimated

• No allowance for dynamic load (ramps, joints, towing)

• Wrong material for the floor or environment

• Cheap substitutions to save cost upfront

That last one usually costs more later.

Quick reality check: load per castor

Total Load ÷ Number of Castors × Safety Factor (1.25–1.5)

This allows for uneven loading and movement forces.

It’s simple, but getting this wrong is one of the biggest causes of premature failure.

Not all wheels are created equal

• Rubber – best for rough floors, quiet, forgiving

• Polyurethane – strong, great on concrete, won’t flat spot easily

• Cast iron – tough and durable, but hard on floors

• Nylon – cost-effective for smooth surfaces

• Pneumatic – ideal for uneven ground

• Antistatic – for sensitive environments

There is no “best wheel”. Only the right wheel for the job.

If your equipment isn’t performing properly, it’s worth looking underneath

If you are dealing with:

• Frequent wheel replacements

• Equipment that is hard or unsafe to move

• Ongoing maintenance issues that keep coming back

There is a strong chance the problem sits with the original wheel and castor specification.
