Do you know the brand of the spherical bearing metal to metal type? Metal type spherical bearing need oil lubrication on a regular basis. Its aim is to supplement the use of cost in the process of lubricating oil, discharge ageing oil and lubricating oil contained within the metal oxide, etc. Metal type spherical bearing is mainly used for ShiJiaJing load situations. For example, when the plane landed, applying large bearing load of landing gear, the bearing static, while landing gear down when the bearing on low load. Using the heat treatment of bearing steel, stainless steel inner ring 440 c and 410 stainless steel, alloy steel 4130 outer spherical bearing with Gao Jing load performance, can meet the demand of small deformation under high load. Al - Bz outer ring: a vibratory load state and difficult to the characteristics of sintering qualified lubrication condition. About half of the static load performance of stainless steel outer ring. A Be - With 17 - Cu inner circle 4 ph outer spherical bearing: apply adequate lubricating oil, is suitable for the occasion of high load, low speed oscillation. The spherical bearing load groove: no plastic processing, can improve the hardness of outer ring and inner ring at the same time. Therefore apply to require high wear resistance and high load situations, such as construction machinery hydraulic cylinder. Adopted the INCONEL ®, STELLITE ®, A286 when used under the environment of high temperature, creep properties of nickel alloy steel. In addition, this bearing when use is often beyond the allowable temperature range of grease, so commonly used with dry film lubrication, such as silver plating processing of solid lubricant.
