MR-H3A high speed ring block wear testing machine

MR-H3A high – speed ring block wear testing machine is mainly used for the lubrication performance evaluation of various lubricating oils and greases. It is especially suitable for the evaluation of the anti-scratch performance of medium and high-grade automotive gear oils. It can also be used for the lubrication performance evaluation of solid lubricating materials. Abrasion test of various metal and non-metal materials to determine the friction and friction coefficient of various materials. This machine has a wide range of application prospects in the field of tribology, technical fields, petrochemical, machinery, energy and other industries.
