Product Overview

This machine is used to test office chairs by placing an unloaded chair on a horizontal work surface. The chair is pushed or pulled over a distance of 550mm at a speed of 50mm/s. A force is applied 200mm above the work surface, and the required force to push or pull the chair is recorded. The rolling/sliding resistance is measured, with the average resistance calculated over a range of 250mm to 500mm.

Product Application:

The Office Chair Caster Rolling Resistance Testing Machine is designed for durability testing of chair casters. It is primarily used by office chair manufacturers during the production process to ensure that casters meet relevant standards and internal quality requirements. This ensures the overall quality and performance of office chairs.

Product Features:

Precise Measurement:
- Equipped with high-precision force and displacement sensors, the machine can accurately measure the resistance encountered by the casters during rolling and record displacement changes. This provides reliable data for performance evaluation.
Adjustable Parameters:
- Parameters such as testing speed, load weight, and stroke can be flexibly adjusted to meet different testing requirements. For instance, models like the XQ-X205 Rolling Resistance Testing Machine offer adjustable testing speeds, load weights as per standards, and testing strokes up to 500mm.
Multiple Testing Functions:
- In addition to rolling resistance testing, some machines also feature other capabilities, such as:
  - Rotational Resistance Testing
  - Static Load Testing
  - Dynamic Load Testing
- These functions allow for a comprehensive evaluation of caster performance.
Intuitive Data Display and Recording:
- Features a microcomputer or computer-based control system with a liquid crystal display (LCD) or touchscreen.
- Real-time data such as resistance, speed, and stroke can be viewed during the testing process.
- Data can be printed directly via a mini printer or exported via a USB drive for further analysis.
Safety Protection Mechanisms:
- To prevent damage to the equipment or injury during testing (e.g., due to caster failure), the machine is equipped with safety mechanisms such as automatic shutdown and mechanical protection.
