Powder metallurgy bearings (PM) are a one-of-a-kind, highly developed method for producing ferrous and nonferrous parts. It is a versatile, cost-effective, and ever-expanding technology that is rapidly gaining global traction. To achieve uniform particle distribution, the PM process begins with the thorough blending of carefully weighed powdered metals or alloys. Bronze, brass, nickel, silver, iron-nickel, and various grades of stainless steel are examples of common metal powders. The resulting blends may contain predetermined amounts of die lubricants, graphite, and other additives.
Sintered oil-bearing (including the amount of graphite 1% -4%) manufacturing process is simple, low cost, under PV <18 ~ 25 kg-cm m / cm 2 · sec situation, can replace bronze, babbitt and other non-oil antifriction bearing advertising impressions First, vulcanized powder metallurgy products Objective (a) of vulcanized
As a leading powdered metal bearings manufacturer, we have more than 40 years of experience supplying bearings to the Appliance, Automotive, Lawn & Garden, Tool, and Motor Industries. Our precision powdered metal bushings and bearings can be found in many applications ranging from control systems to fractional HP Motors.
After treatment, Powder metallurgy bearings the most noticeable role of porous sintered iron sulfide is good dry friction properties. It is a satisfactory self-lubricating material in oil-free operating conditions (that is, or cannot be allowed to refuel refueling), has good seizure resistance, and reduces the bite-axis phenomenon. Furthermore, the friction properties of this material differ from those of general anti-friction materials. When the pressure ratio exceeds a certain value, the friction coefficient begins to change little. When the pressure ratio exceeds a certain value, the coefficient of friction increases sharply. And after the treatment, the friction coefficient increases its pressure ratio then the pressure in a wide range increases but decreased through the porous sintered iron sulfide. This is an excellent anti-friction material.
Antifriction powder metallurgy products Porous immersion oil is an important step in improving the corrosion resistance, wear resistance, and life of powder metallurgy products. After immersion oil treatment, lube oil enters the product pores and sets the occurrence of dynamic friction, heat, and bearing temperature rise, the oil case of thermal expansion, flows out from the pores to the shaft and sleeve when the shaft is rotated. Oil autoplay, lubricating oil film formation, and friction reduction It is possible to keep immersion oil products from oxidizing.
Waxing process powder metallurgy bearings is placed in the wax on a wax cylinder and heated to 60 80 °C, so the wax melts, clean the article is immersed in liquid wax and removed immediately, which is coated on the surface of the article a uniform layer of wax, cool before packaging.

The proportions of liquid paraffin wax and petrolatum vary depending on the season. Furthermore, Vaseline is intended to improve the fastness of liquid wax after drying without cracking. When the temperature is high, use less Vaseline, and petroleum jelly may be used to increase the ratio when the temperature is low. Typically, 20% petrolatum and 80% paraffin wax are used.
