  • The roller cutter is mainly suitable for the excavation of ventilation shaft in the mine. In view of the requirements of the bit's wear resistance and sealing in the harsh environment of the mine, our R & D personnel have adopted big diameter wedge inserts on the main cutting rows of the product to improve the wear resistance, while the high-quality NSK thrust bearing has improved the bearing capacity, and the floating oil seal imported from Germany has strengthened the production of the roller cutter.The sealing sustainability of the product extends the service life of the bearing, and with the use of A&B cutter types, the full coverage of the bottom hole crushing belt can be realized.
