IKO joint bearing lubrication and precautions

IKO refueling type articulated bearings are able to move without refueling even when the load load is low, but they are generally grease-lubricated. Regularly add grease. It is recommended to shorten the fueling interval at startup. Most lubricants use lithium soap grease containing MoS2 (M0S2) (NLGI consistency No. 2). Non-oiled joint bearings are maintenance-free products that do not require refueling. However, the use of lithium soap grease before use can ensure a longer life. In addition, the grease filled around the bearing can play a role in preventing foreign matter intrusion and bearing corrosion. The number of oil holes in the inner and outer rings is shown in Table 15. Table 14 Load direction coefficient b1 Load direction load direction coefficient b1 1 0.2(1) Always alternately note (1) Indicates the load direction coefficient when a slow alternating load acts. If it is a fast alternating load, it will rapidly drop. Please consult Qingdao Ruijing Mechanical and Electrical Equipment Co., Ltd.

  Working temperature range Bearings with gaskets Operating temperature range -30 to 80°C. The maximum permissible temperature of bearings without gaskets is 180°C for the refueling type and 150°C for the unfilled type. ■ Handling Precautions Design of the shaft Generally, when the load is heavy, it can slide on the inner diameter surface of the shaft and the inner ring. Therefore, the hardness of the shaft needs to be 58HRC or more, and the surface finish is within 0.8μmRa. In addition, since the shear stress and bending stress of the shaft are mostly below the static load capacity of the IKO joint bearing, it is necessary to pay special attention to the strength of the shaft. Design of the bearing housing The bearing housing needs to have sufficient rigidity and does not deform due to the load. When using a bearing housing of the type shown in FIG. 6, the bearing housing must be designed to have the following strength. Figure 6 Shape of the bearing seat Figure 7 Stress concentration factor
