UCP series spherical bearing with seat is the most representative form of bearing assembly. The bearing seat P has a flat bottom and solid. This series has two types: UCP200 and UCP300. UCP300 series bears more load than UCP200 series. Because the root of the mounting part of the bearing seat is equipped with a reinforcing rib, it is a high-strength structure for compliance in all directions. In addition, bearing seat P can also be connected with UK, UEL, NA series bearing components, and UK module pass circular taper hole (UKP), and the nominal model of the applicable adapter sleeve is attached to the module engineering model. The main uses of this series: transmission device, fitness equipment, harvester, etc. For example, the cast steel outer spherical bearing with seat HCP207 (UELP207), the solid seat outer spherical bearing UCP205, HCP206 (UELP206), and the FGJ205 single outer spherical bearing with seat and FGJ double outer spherical ball bearing (one bearing seat is equipped with two outer spherical ball bearings) designed according to the customer's requirements have been applied to the corn harvester and peanut harvester, and have been widely praised by customers after use.
