How long is the service life of rubber casters?

Key Factors and Scenario References for Rubber Caster Lifespan

Rubber caster lifespan is typically 3 months to 3 years, affected by the following factors:

Load and Frequency

Overloading (>120% of the rated load) shortens lifespan by over 50%;

High-frequency use (e.g., a shopping cart 50 times a day) shortens lifespan by 30%-40% compared to low-frequency use.

Floor Conditions

Smooth Floors (Ceramic Tiles/Wooden Floors): Lifespan 1-3 Years;

Rough Floors (Cement/Gravel): Lifespan 3-12 Months;

Humid/Oil-Contaminated Environments: Lifespan Reduced by 20%-30%.

Material Quality

Ordinary Natural Rubber: 3-12 Months;

Synthetic Rubber (Nitrile/Chloroprene): 6-24 Months;

Poor-Quality Casters: Lifespan Reduced by Only 3-6 Months.

Maintenance

Regular cleaning, lubrication, and tightening can extend lifespan by 20%-30%;

Lack of maintenance can reduce lifespan by half.

Key Measures to Extend Lifespan
① Strictly match loads (allow a 20% margin);
② Optimize the surface and remove debris;
③ Choose synthetic/wear-resistant rubber materials;
④ Regular maintenance: remove debris, lubricate bearings, and check for cracks.

Summary
Lifespan depends on the intensity of use, environment, and maintenance. Light household use can last 2-3 years, while harsh industrial environments may only last 3-6 months. Weekly inspections for wear and rotation are recommended, and timely replacements are recommended to ensure safety.
