Air-lift Reverse Circulation Roller Cutter

Raise Boring Roller Cutter—— Greate's raise boring roller cutters adopt advanced design concepts and mature machining processes. Sizes range from 8" to 15", compatible with various domestic and international raise boring machine models, and widely applicable to various cutterheads with diameters from 0.6 m to 12 m, meeting the needs of various raise/shaft construction projects.

——Large-diameter roller—steel ball—roller bearing structure, with reasonable design parameters, maximizes bearing load capacity and effectively extends bearing life. Specially selected grease further reduces bearing wear.

——High-performance metal seal rings, energy rings made of special materials, and rigorous greasing processes effectively ensure the reliability of the sealing system and greatly improve the service life of the bearings in harsh environments.

——Optimized cutting structure, combined with special alloy tooth grades and shapes, effectively ensures the rock-breaking efficiency of the roller cutter.

——Specially designed positioning pins are easier to operate and disassemble, with good lubrication performance.

Our roller cutters can also be customized according to the customer's cutterhead and cutter seat system.
