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.
