Office Chair Casters
Key points about office chair casters are as follows:
In terms of price, the prices of office chair casters vary significantly depending on their size and material. For example, a 1.4-inch load-bearing caster costs ยฅ1.36 each, suitable for scenarios with high load-bearing requirements; a 1.5-inch wear-resistant caster is priced at ยฅ3.8, emphasizing durability; a 2-inch insert-rod flat-plate caster costs ยฅ3.1, suitable for situations requiring flexible movement. Additionally, some high-end casters may be made of polyurethane or nylon materials, and their prices will further increase, but specific judgments need to be made based on the brand and function.
Type selection should be matched according to actual needs.
- Swivel casters: Support 360-degree rotation, suitable for scenarios that require frequent directional adjustments, such as open office areas or meeting rooms.
- Brake casters: Fix the casters with a locking device to prevent the chair from sliding accidentally, often used in environments requiring stability, such as laboratories or beside drafting tables.
- Silent casters: Use special materials or structural designs to reduce noise during movement, suitable for libraries, hospitals, or nighttime office scenarios.
- Heavy-duty casters: Have stronger load-bearing capacity (usually exceeding 100 kilograms), suitable for heavy users or chairs with heavy objects stacked on them.
Replacement methods vary depending on the caster's fixing method.
- Insert-rod casters: Gently tap the top of the caster with your hand or a tool (such as a rubber mallet) to remove it from the chair leg's insert hole. When installing, align it with the insert hole and press firmly.
- Screw-type casters: Use a screwdriver or wrench to unscrew the fixing screws, remove the old caster, align the new caster with the screw hole, and tighten the screws to ensure a secure connection.
Precautions: Before replacement, confirm that the caster size matches the chair leg to avoid installation failure or damage to the chair leg due to non-compliance with specifications.
Cleaning and maintenance can extend the lifespan of casters.
- Hair removal: Use small scissors or tweezers to clean the hair entangled in the gaps between the caster axle and the caster body to prevent blockage from affecting rotation.
- Dirt cleaning: Wrap a wet face towel around the caster and roll it back and forth to wipe off surface stains; for stubborn dirt, use a cotton swab dipped in a small amount of neutral detergent for local treatment.
- Drying treatment: After cleaning, dry the caster with a dry cloth to prevent rust or corrosion caused by residual moisture.
Regular inspection: Check monthly whether the casters rotate smoothly. If there is any stuttering or abnormal noise, clean or replace them in a timely manner.
