Office Chair Caster Durability Tester

The Office Chair Caster Durability Tester is designed to evaluate the rolling durability, structural reliability, and service life of office chair casters under controlled load and motion conditions. The equipment simulates long-term rolling, rotation, stopping, and reversing movements of chair casters on floor surfaces to assess wear, deformation, and functional degradation. It is widely used for quality control, product certification, and durability verification of office seating products.

Application

(1) Durability and life-cycle testing of office chair casters under specified load conditions.

(2) Rolling wear evaluation of casters used on hard floors, plastic floors, and resilient floor coverings.

(3) Performance verification of complete office chairs equipped with multi-caster bases.

(4) Quality control testing for chair manufacturers during product development and mass production.

(5) Comparative testing of different caster materials, wheel structures, and hardness grades.

(6) Reliability testing of casters for use in commercial offices, public buildings, and educational facilities.

(7) Compliance testing for office chair products required to meet national and international standards.

Test Procedure

(1) Install the floor sample securely on the test base using adhesive or fixing method as required.

(2) Mount the office chair or caster assembly on the sample support platform.

(3) Apply the specified load to the caster load block.

(4) Set platform speed, caster speed, and test cycle parameters via the PLC touch screen.

(5) Start the test; the platform rotates, stops, and reverses automatically according to the preset program.

(6) Continue the test until the specified number of cycles is reached or failure occurs.

(7) Inspect casters and floor surface for wear, deformation, or functional failure.

Maintenance Information

(1) Regularly inspect caster fixtures and load blocks for secure fastening.

(2) Clean the platform and floor base after testing to prevent debris accumulation.

(3) Periodically check PLC control system and reducer operation.

(4) Replace worn floor samples promptly to ensure test accuracy.

(5) Store the equipment in a dry, stable laboratory environment.
