Exercise bikes, strength machines, rowing machines and other stationary fitness equipment experience repeated pedaling, pulling, pushing and impact loads. Fatigue can cause weld cracks, bearing wear, cable elongation and loose pedals. A programmable endurance tester reproduces long-term use and records the failure process.

1. Multi-Axis Loading

Pneumatic, electric or servo actuators can be used. Pneumatic systems suit long fixed-force cycling, while servo systems provide precise force, displacement, speed and waveform control. Complex products may require synchronized axes.

2. Fixtures and Installation

The sample should be installed in its normal use condition. Loading points should match human contact locations. Pedals, handles, seats, backrests and cables require different fixtures.

3. Test Procedure

1. Confirm equipment category, load points and cycle target;
2. Install the sample and record initial clearances;
3. Run low-speed motion checks;
4. Set force or displacement, speed, dwell and cycles;
5. Configure overload and overtravel protection;
6. Inspect welds, bearings, fasteners and cables at planned intervals;
7. Perform final function and residual-deformation checks.

4. Data and Selection

The system should record force, displacement, cycles and abnormal stops. Multi-product laboratories benefit from modular frames, movable actuators and recipe management. LSKFT can configure single-axis, multi-axis, torque, pedaling and combined endurance systems.
