Products Description
XMF Series: Floating Bearing Rubber Seal Roller Cone Bits
The XMF series bits adopt a unique floating bearing structure technology, which greatly reduces the friction heat and wear of the bearing system, making it more suitable for high speed, high drilling pressure, and medium speed medium drilling pressure enhanced drilling processes, greatly improving the bearing life, bearing reliability, and bearing stability of the bit.
Structural characteristics:
1. The floating element is made of new materials with high strength, high elasticity, high temperature resistance, and high wear resistance, and the surface is treated with solid lubricant.2. Reasonable bearing clearance design allows floating bearings to reduce the relative linear velocity of the bearing pair while reducing the temperature rise of the friction surface, effectively improving the bearing life and reliability under high
drilling pressure or high-speed drilling process conditions.
drilling pressure or high-speed drilling process conditions.
3. The O-ring seal of the bearing adopts wear-resistant and high-temperature resistant hydrogenated nitrile rubber; The
carefully designed convex boss at the outer end of the sealing chamber improves the reliability of the sealing.

4. Steel ball locking teeth, suitable for high rotational speed.
5. Use a new type of lubricant that can withstand high temperatures of 250 ° C and resist wear.
6. The back of the dental palm is embedded with hard alloy teeth, effectively protecting the tip of the dental palm; Effectively prevent palm back wear and prevent the oil cup from falling off.
