Abstract Uniform gradient magnetic field can, more accurately, reflects the friction performance of ferrofluids in the magnetic field. Based on this, two coils, which could produce uniform gradient magnetic field, were constructed and placed on the commercial UMT3 tribo-meter. Using the poly-α-olefin synthetic oil (PAO)-based magnetic fluids as the lubricant, the tribological properties were tested with different loads, different reciprocating frequency and various magnetic field. The results show that: when the load and reciprocating frequency are constant, the friction coefficient decreased with the increase of the magnetic field; when the load, a uniform gradient magnetic field, the friction coefficient also decreased with the increase of the reciprocating frequency. Comparing with no magnetic field, the ferrofluids has higher bearing capacity and a longer wear life in the uniform gradient magnetic field.
