Oil Field Drilling Rig Spare Part Kelly Roller Bushing

DALON self-lubricating sintered bronze bushing are manufactured of pressed copper and tin powders by sintered technology and impregnated with lubricating oil and high porosity (20-25% in volume). The oil contained in the porosity provides a constant lubrication between bearing and shaft, the system does not need any additional external lubricant, allows this type of sintered bronze bushing to work under hydrodynamic conditions. which resulting in a very low friction coefficient and maintenance-free for general engineering applications.

DALON BUSHING INTRODUCTION:

DALON Roller Bushing consist of a sintered bronze body. The main feature of Roller Bushing is their porous design, which contains oil lubricant, which should be the viscosity decrease due to increasing operating temperatures due to friction, the oil leaks out. At higher speed, a lubrication wedge develops, which lowers the bushing's friction.

The powdered metallurgy process is a mass production process that can reduce costs to a level that can be startlingly low when compared to CNC machining. An added benefit of the sintered Roller Bushing are the unique pores that are formed in the structure of the metal. These pores can serve as a reservoir for lubricant, providing a passage to the bearing surface. This unique feature adds the benefit of self-lubrication to many powdered metal bearings.

 

  1. High load oil-embedded Sleeve Bearings: This kind of Roller Bushing increased iron content which makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings. Also they running at lower speeds
  2. High load Ultra low Friction oil embedded sleeve bearings: This kind of bearings used for frequent starts and stops in high load applications.
  3. Food Industry oil embedded sleeve bearings: These bearings used oil is suitable for incidental contact with food.
  4. Multipurpose sleeve bearings: These bronze bearings with lead are strong, wear resistant and excellent at handling shock loads.
  5. Oil filled SAE841 Bronze bearings: Sintered bronze powder SAE841 without lead impregnated with SAE 30 oil to make this material self—lubricating.
  6. SAE 660 Bronze bearings: These bearings offering excellent antifriction qualities, SAE660 bronze also offer goods strength and wear resistance. It’s often used for bearings, bushings, and thrust washers.
  7. High temperature Graphite filled 841 bronze Bushing: These bushing have an excellent alternative to oil filled bushing, graphite filled bronze provides dry lubrication in temperature as high as 370℃
