The summary of products
The SMZ series integral installation vertical thrust sliding bearings mostly are used for the vertical rotary electrical motors and other equipment, so as to support the axial and radial force. It mainly includes thrust pads (with dished springs and supporters), guide pads, supporting board (used for supporting of the thrust pads), seat of guide pad, regulation bolt, oil-water cooler, shell, expansion sleeve of thrust collar, oil seal device, inside and outside oil baffle tube and so on. According to the different operation condition and the size of load of the bearing, it can adopt different mode of lubrication: self-lubrication or pressure oil cycle lubrication. For the self-lubrication bearing, its cooling often adopts self-cooling or via the water passed through radiator installed in the shell. The lubricant through the groove designed on the supporting board inflow between the thrust collar and inside oil baffle tube. After enter in to the thrust pads and working surface of the guide pads, outflow from the guide bearing seat and outside oil baffle tube, cooling by the oil-water cooler then go to the recycle.

Label of the SP series vertical thrust sliding bearings
The type of this series bearing shows as follows

technical character
SMZ series bearings were developed bearing unit based on the SM series bearings. It is better than the SM series bearings to have no use for designing bearing tank and its cooling system by the users themselves. They can more conveniently and directly take the bearing unit to use for necessary equipment (electric motor). These series bearings except all the feature of SMZ series bearings, also they have the following feature:
1.The casting bearing box with radiating ribs enable the unit of integral bearing to has the reliable rigidity. The anti-vibration performance is good. The appearance is exquisite. The structure is more compact and reasonable.
2.Adopting upper thrust collar insulation structure enables the insulation of the bearing to be more credible and safer.
3.Adopting eliminating the gap device on the inside of thrust collar and journal carry out clearance assembly and without clearance operation. The whole parts of the bearing once assemble without disassembly. Accordingly to shorten the time of assembly of the bearing greatly.
4.Adopting the best oil-water cooler and anti-leakage structure enable the effect of cooling of the bearing to be better, the operation to be more credible. Integral bearing unit adopts double anti-leakage structure enable the bearing without leakage during the operation. When the bearing uses water cooling device, usually the cooler adopts oil-water cooler made of ring-like double metal wing piece tube or copper wire cord reed pipes. The working pressure is 0.3~0.5Mpa. Velocity of flow is 1.2~1.5m/s. The testing water pressure is twice of working pressure. Not allow leakage within 30 minutes, capacity of the water supplying of the cooler see table 2. The water quality is deposited working water.

Specification and basic data

<1>Fa shows the supportable down loads of bearing; F shows the max. supportable moment down loads
<2>with "*" mark shows when the bearing work in this condition the lubricant is L-TSA32, other working conditions the lubricant is L-TSA46.
