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

Time：Nov 28,2025

In warehouses, workshops, shopping malls, and hospitals, casters are the “most diligent movers”—yet they’re also the “consumables” most easily overlooked. Many users treat casters as “disposable parts,” only to regret it when their carts suddenly jam, emit piercing noises, or even have their wheels come loose.

Based on the field experience of over 50,000 customers with Global Casters, 80% of premature failures can be avoided simply by conducting a routine 10-minute inspection—resulting in an average lifespan extension of 30% to 50%. Today, we’ve broken down this “10-Minute Inspection Method” into five easy-to-follow diagrams. Just follow them step by step!

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

I. Understand Why Casters Break Down at a Glance from a Single Table

| Failure Mode | Culprit | Inspection Keywords |

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

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

| Stent fracture | Vibration-induced loosening, corrosion | Wobbling/cracks |

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

| Stiff steering | Foreign objects, rust | 360° inflexible |

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

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

① Look: A quick glance

- Wheel surface: Replace if worn below the marked line; replace if cracks exceed 5 mm; remove embedded stones using a screwdriver.

- Bracket: Peeling paint + yellow rust → Remove rust with a wire brush and touch up with paint; weld crack → Replace the bracket directly.

② Spin: Push once every two seconds

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

- The swivel wheels can be rotated by hand when lifted off the ground, with a 360° rotation free of any sticking. If there’s sticking—add lubricant and try again; if it still doesn’t work—disassemble the bearing.

③ Shake: Check for looseness with three gentle shakes.

— Gently shake the bolt with a wrench; if you can see a gap, tighten it diagonally. If it still wobbles after tightening, the thread has stripped—replace the bolt with a new one and add a spring washer.

- If the bearing shaft clearance exceeds 3 mm, add adjustment shims or replace the assembly.

④ Note: Lubricate diligently throughout the four seasons.

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

- Before applying new grease, first wipe away the old grease. The bearing cavity should be “half full”—excess grease equals dust attraction.

⑤ Matching: Five-step scene alignment

- Cement 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.

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

3. Tools: 1 wrench + 1 record sheet

Tool kit (market price < 100 yuan):

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

Record Form (handwritten is acceptable):

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

IV. Three Common “Lazy Traps”

1. Tightening bolts without removing rust → Rust cracks widen, and the bracket breaks within 3 months.

2. Applying too much grease at once → excess grease attracts dust, causing the bearings to wear out faster.

3. After replacing the floor with epoxy flooring, the old rubber wheels were still used → friction doubled, and after two weeks of dragging, the wheel surfaces began to peel off.

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

V. A one-sentence summary

Good casters rely 30% on manufacturing and 70% on maintenance.

10 minutes a day: eyes look → hands rotate → wrench swings → grease is applied as needed → scenario matching,

Leave the hidden dangers at the site, and leave the profits and safety to the enterprise.
