Sealed Bearing Reamer Hdd Roller Trenchless Hole Opener
Introduction
300mm tapered roller reamer Tapered roller reamer is a commonly
used drilling tool in rock formation excavation. The tapered roller
reamer produced by our company is suitable for all kinds of
trenchless drilling rigs, and can be used for the expansion of
various rock formations. The specification range is Φ260-1800mm.
Advantages
Best price and high quality
Bearing type: 1. Sealed bearings and non-sealed bearings. 2. Metal
sealed journal bearings. 3. Rubber sealed journal bearings
Cutting structure: All surfaces of the back cone and teeth are
hardened, which improves the shape of the steel teeth and welding
materials, and presents a higher tooth profile
Application structure: low compressive strength and high
drillability softness, such as shale, clay, salt layer, etc.
All our activities have obtained ISO 9001:2008 and API
certification for products and services. At the same time, mature
production technology can ensure that the quality meets
international requirements.
