Featured - Sealed bearing

This is our patented Hybrid Bearing premium product. This product is a Sealed bearing product that gives higher life due to its ability to revert to air bearing and maintain life longer.
New patent (DH Series) is a hybrid that once the seal fails, the bit reverts to an air-bearing product which will extend the total bit life. This provides longer rotating hours than typical sealed-bearing products. This new patent is especially effective in tough drilling conditions and hard rock applications such as iron ore where high pulldown is required. This hybrid is also extremely successful for applications with excessive groundwater.
