Cylindrical roller bearing professional use: cylindrical roller bearings are mainly used in motors, machine tools, petroleum, rolling mill loading and unloading transfer machinery and various industrial machinery.
Cylindrical roller bearing features: cylindrical roller bearing is a separate bearing; device and disassembly is very convenient. Cylindrical roller bearings are divided into single row, double column and four columns.
Cylindrical roller bearings can be divided into single-row, double-row and multi-row cylindrical roller bearings. Among them, there are more single-row cylindrical roller bearings with cages. In addition, there are Cylindrical roller bearings of other layouts, such as single or double row full complement rollers.
Single row cylindrical roller bearings are classified into N type, NU type, NJ type, NF type and NUP type according to the different ferrule ribs. Cylindrical roller bearings can receive large radial load; according to the layout of the ferrule ribs It also accepts certain one-way and two-way axial loads.
NN type and NNU double row cylindrical roller bearings are compact in layout; strong in rigidity. Large bearing capacity; deformation after load. 蠖嗍糜诨.岬, FC, FCD, FCDP four-row cylindrical roller bearings are acceptable Large radial load; mostly used in heavy machinery such as rolling mills.
Cylindrical roller bearings: can accept heavy radial loads at high speeds; cylindrical roller bearings with single row EC type have optimized internal curves; can improve the radial and axial load of the bearings; progress together to the point of view and alignment Error conditioning and improved smoothness; the full-roller bearing that eliminates the cage can have the most number of intended rollers. Suitable for very heavy and medium speed conditions

The oil well Tricone Drill Bit advantage  

1. Adopt floating bearing structure, the floating element is made of new material with high strength, high elasticity, high temperature resistance and high wear resistance, and the surface is treated by solid lubricant. While reducing the relative linear velocity of the bearing pair, the friction surface temperature rise is reduced, and the bearing life and bearing reliability under high drilling pressure or high speed drilling process conditions can be effectively improved.


2. Adopt high precision metal seal. The metal seal consists of a carefully designed metal seal ring as the axial seal of the bearing. The two highly elastic rubber supply rings are located in the palm and cone seal area as static seals. The optimized seal compression ensures two The metal ring sealing surfaces are always in good contact.

3, the steel ball locks the cone, adapt to high speed.

4. It adopts a full rubber oil storage bladder that can limit the pressure difference and prevent the drilling fluid from entering the lubrication system, which provides a good lubrication guarantee for the bearing system.

5, using a new grease that can withstand high temperatures of 250 ° C, anti-wear.

6. The insert bit adopts high-strength and high-toughness hard alloy tooth. The optimized design of the number of teeth, the number of teeth, the height of the tooth and the unique shape of the alloy tooth fully exerts the high wear resistance and excellent cutting ability of the insert bit. The new wear-resistant material of the steel tooth bit surface welding, while maintaining the high mechanical drilling speed of the steel tooth bit, improves the life of the bit cutting teeth.
