Office Chair Caster Knowledge

The knowledge of office chair casters covers various aspects such as types, replacement, functions, testing, structure, product characteristics, and application scenarios.

Types and Suitable Scenarios: Office chair casters are mainly divided into regular casters and PU casters. PU casters are made of soft materials, suitable for smooth surfaces like hardwood floors, reducing scratches; regular hard casters are suitable for carpets or wear-resistant floors. Selecting the caster type based on the floor material can optimize performance and extend the floor's lifespan.

Replacement Methods and Precautions: To replace casters, first identify the connection method. If it is a clamp-fixed type, invert the chair, forcefully pull out the old caster, and then snap in the new one until you hear a 'click' indicating it is in place; if it is a threaded connection, unscrew the old caster and screw in the new one. Key precautions include:

• Consistent Size: The new caster must be the same size as the others to prevent the chair from tilting;
• Matching Type: Use hard casters on hard floors and soft casters on carpets to ensure smooth movement;
• Installation Strength: For casters with a snap-in pin design, ensure the snap is in place; for threaded types, tighten them to prevent loosening.

Functions and Performance Testing: Casters have both mobility and locking functions; pressing the brake can fix the position. Performance tests include:

• Ultimate Load Test: Under a heavy load of 113KG, high-strength composite materials and optimized structures prevent deformation, ensuring safety;
• Durability Test: Through 100,000 slides (including 2,000 obstacle simulations) to test hardness and toughness, preventing fracture risks.

Structure and Mainstream Product Characteristics: Casters are connected to the bracket via a rotating shaft, enabling 360-degree steering, divided into fixed-direction casters (fixed direction) and swivel casters (flexible steering). Mainstream products address pain points through material innovation:

• Silence: Rubber materials are specially treated to reduce friction noise;
• Floor Protection: Soft caster bodies prevent scratches;
• Load-Bearing Stability: The snap-in pin design allows a single caster to dynamically bear over 50 kilograms, with a four-caster combination supporting 200-kilogram office chairs.

Application Scenario Requirements: For office scenarios, silence is prioritized; for home scenarios, floor protection is emphasized; for industrial scenarios, high load-bearing capacity and wear resistance are required. Modular design is becoming a trend, allowing quick adaptation to different scenarios by replacing the caster body or adjusting the bracket.
