Product details
Introduction:
DQAThe type end cover sliding bearing is a side flange installation structure, installed on the equipment's round end cover, using an outer stopper and positioning pin for positioning. referenceDIN31693andJB/T5888-2000Standard design. The bearing seat and bearing shell adopt a double spherical fit, which provides good support stiffness for the bearing shell and has automatic centering function.
The bearing shell adopts a split structure and is in spherical contact with the inner hole of the bearing seat, achieving the automatic centering function of the bearing. The bearing shell is made of low-carbon steel, such as20Casting tin based Babbitt alloy on the surface of steel (a domestic alloy grade)ZSnSb11Cu6Imported alloy gradesTEGO STAR738Among themTEGOSTAR738Does not contain lead element); The oil inlet edge of the bearing shell has been specially optimized to ensure safe, reliable, and long-lasting operation of the bearing.
The bearing shell varies depending on the axial thrust it needs to withstand4 Form: Without thrust surfaces on both sidesQType bearing shell (not bearing axial thrust), with flat thrust surfaces on both sides with oil inlet groovesBType bearing (capable of withstanding small, short-term axial thrust), with fixed oil wedge thrust surfaces on both sidesKType bearing (capable of withstanding moderate axial thrust), with elastic circular thrust pads on both sidesTType bearing (capable of withstanding significant axial thrust). Elastic circular thrust pads have good damping characteristics and can effectively absorb axial impact loads.
For bearings used in working conditions such as high starting pressure, frequent start stop, long-term shutdown, low starting power, low speed or frequent forward and reverse rotation, it is recommended to use a bearing structure with high-pressure oil lifting.
Mainly used for sliding bearings of DQ series, ZQ series, ZS series, RENK bearings (EF, EM, EG, ER series)
Our company produces horizontal sliding bearings according toDINstandard sumJB/TThe standard has been optimized and modularized, with a wide range of applications, easy installation and use, good universality and interchangeability, which can effectively reduce spare parts and inventory; The product has the advantages of compact structure, reasonable design, high reliability, low noise and vibration, and easy use and maintenance.
