The secret to "longevity" for casters: A 10-minute daily inspection can instantly boost their lifespan by 50%.

Time：Nov 25,2025

In warehouses, workshops, shopping malls, and hospitals, casters are the "busiest movers," yet they’re also the "consumables" most easily overlooked. Many users treat casters as "disposable parts," only realizing their mistake when a cart suddenly jams, emits an ear-shattering noise, or even causes the wheel to come loose—often too late to remedy the situation.

Global caster brand's experience from over 50,000 customer sites shows: 80% of premature failures could be easily prevented with just a 10-minute routine inspection, extending the average lifespan by 30–50%. Today, we’ve broken down this "10-Minute Inspection Method" into 5 easy-to-follow diagrams—simply follow along!

------------------------------------------------

I. Understand Why Casters Fail at a Glance

| Failure Mode | Behind the Scenes | Inspection Keywords |

| Wheel surface smoothed | Ground friction, overload | Thickness ≤ 2/3 of original value |

| Bearing Seized | Lack of Lubrication, Dust Contamination | Stiff Rotation |

| Stent Fracture | Vibration Loosening, Corrosion | Wobbling/Cracks |

| Corrosion and Rust | Water Stains, Acids & Alkalis | Rust Spots, Paint Chipping |

| Stiff Steering | Foreign Objects, Rust | 360° Lack of Smoothness |

------------------------------------------------

II. 10-Minute 5-Step Inspection Method (with Mnemonic)

① Look: A quick glance

- Tire tread: Replace if worn below the indicator line; replace if cracks exceed 5 mm; remove embedded stones by gently prying them out with a screwdriver.

- Brackets: Paint chipping + yellow rust → Clean rust with a wire brush, then touch up with paint; weld seam cracks → Replace the bracket directly.

② Rotate: Push once every two seconds

- Push with both hands, using "silence + gentle gliding."

- The universal wheels rotate freely when lifted off the ground, offering 360° motion without any sticking points; if there is a sticking point—try applying some oil first. If that doesn’t work, it’s time to disassemble the bearing.

③ Shake: Check for looseness in three directions

- Gently wiggle the wrench against the bolt—notice any gaps → Tighten diagonally; if it still wobbles after tightening, the threads are stripped—replace the bolt along with a spring washer.

- If the bracket shaft clearance exceeds 3 mm, add an adjustment shim or replace the assembly.

④ Note: Lubricate diligently throughout the four seasons

- Ordinary lithium-based grease: lubricate once every 2 months; for cold storage/heavy-duty applications, lubricate once a month.

- Wipe off the old grease before applying new grease, and fill the bearing cavity to about "half full"—overfilling will attract dust.

⑤ Setup: Five-Step Scene Preparation

- Concrete floor → Polyurethane wheels;

- Gravel/Outdoor → Choose wide-tire rubber off-road wheels;

- Acid-alkali workshop → Replace with phenolic or stainless steel wheels;

- Cold storage ≤ -20 ℃ → Cold-resistant nylon wheels;

- High temperature ≥120 ℃ → Cast iron wheel + high-temperature grease.

------------------------------------------------

III. Tools: 1 wrench + 1 recording form

Tool kit (market price < 100 yuan):

10 mm ratchet wrench, grease gun, small syringe oiler, marker pen, stickers.

Record Form (Handwritten Optional):

------------------------------------------------

IV. Three Common "Lazy Traps"

1. Tightening bolts without removing rust → Rust cracks widen, leading to the support structure breaking within 3 months.

2. Applying too much grease at once → Grease overflows, attracting dust and causing the bearing to wear out faster.

3. After the floor was resurfaced with epoxy, the old rubber wheels were still used → friction doubled, causing the wheel surfaces to peel off after just two weeks of dragging.

------------------------------------------------

V. Summary in one sentence

Good casters depend 30% on manufacturing, and 70% on proper maintenance.

10 minutes a day—eyes watch → hands turn → wrench swings → grease applied as needed → tailored to the specific scenario.

Leave the hidden risks on-site, while reserving profits and safety for the company.
