Office Chair Caster Wheel
Office chair caster wheels come in various types, featuring different installation methods, prices, and testing equipment.
I. Installation Accessories
The T37 hollow caster wheel is a typical representative of computer chair installation accessories. Its installation process requires following specific steps: First, point the arrow on the tray towards the front of the seat cushion to ensure the correct direction; then, align the backrest with the holes on the seat cushion, precisely inserting one side of a hole into the protruding position on the backrest to complete the connection and installation of the backrest and seat cushion. After completing this step, subsequent operations such as loosening the rocking knob, installing the chair legs, and the gas lift can be carried out to achieve the complete assembly of the office chair.
II. Price Differences
The prices of office chair caster wheels vary significantly depending on their types. For example, the gravity self-locking brake-equipped universal caster wheel is priced at 3 yuan. It features a gravity self-locking function that automatically locks under specific conditions to ensure safety during use. The spot stock silent load-bearing universal wheel caster with brake is priced at 0.34 yuan. It is characterized by silence and load-bearing capacity, suitable for office environments with high noise control requirements. The load-bearing PP universal wheel caster with brake is priced at 1.43 yuan. It adopts PP material, offering good wear resistance and load-bearing performance. These caster wheels at different prices meet the needs and budgets of different users.
III. Testing Equipment
The TST-F731 Rotary Chair Caster Dynamic Testing Machine is a professional device used to evaluate the performance of office chair caster wheels. With a rated power of 1KW, it is primarily used to assess the durability and wear degree of office chairs with rotating functions under repeated rotational pressure. This device is manufactured by Dongguan Tester Testing Instruments Co., Ltd., with its origin in mainland China. It is suitable for performing BIFMA 5.1 standard unidirectional/bidirectional rotation tests and EN 1335 standard forward/reverse rotation tests. It features positive and negative rotation angle adjustment (45ยฐ - 355ยฐ) and supports continuous 360ยฐ unidirectional rotation. The rotating table has a diameter of 800 millimeters, with a maximum seat width compatibility of 1000 millimeters. The rotation speed is adjustable within the range of 5 - 20 cycles per minute. The control system employs a programmable logic controller (PLC) and an LCD display, with a maximum test count of 999,999. Additionally, it is equipped with a 113-kilogram weight and an electric hoisting device, operating on a single-phase AC220V power supply. It enables diverse testing requirements by customizing test angles, directions, and dwell times.
