Application for heavy industry sector, F & Z Company strengthened the "fluid technology" industry bearing product range for hydraulic systems and fluid pumps, but also extends the "air handling" sub-industry fans and centrifugal compressor product lines.
For the requirements of these applications, bearings and components must meet these stringent requirements for reliability and efficiency of application functions required. F & Z by providing personalized, tailor-made for the customer programs and sophisticated standard bearings to meet these needs.
Pumping liquids,
The liquid from the low pressure position to the high pressure position.
Or the liquid from a lower level to a higher position where the position of the horizontal position (horizontal height = gravity)
Or liquid transition from low speed to high speed state.
The basic operating principle of the pump are mainly two: the volume change and centrifugal centrifugal principle. Liquid flows into the axial pump, and the fluid is driven by a high-speed impeller. Within the piston pump, the liquid is compressed by the cylinder back and forth movement of the piston.
Applications
Single row cylindrical roller bearings
N, NJ, NU, NUP and may also be full roller or double row cylindrical roller bearings high radial loads, with a small radial clearance to obtain a precise radial guide
Single row angular contact ball bearings
Used primarily as a thrust bearing, single or in series (in a tandem arrangement, they can withstand high thrust loads)
Case the radial load and high axial loads applied to exist in one direction
Ammonia for use in the transportation medium pump will use FP holder (pump)
With a "B" suffix bearing contact angle is 40 °, so that the bearings can withstand higher axial load (pump)
Can also be used with sealed bearings
With optimized geometry design stamping newly developed cage
Double row angular contact ball bearings
Primarily as a thrust bearing used, alone or in series (in a series configuration, they can withstand high thrust loads).
Fit in one direction and high radial load thrust loads
Also suitable holder with ammonia pump FP
Models with a 40 ° contact angle "B" can withstand higher thrust loads
Also suitable for sealing
With optimized geometry of the cage retainer stamping newly developed
Spherical roller bearings
Can be applied to the pump and can withstand high pressure, the bearings can compensate for shaft machining defects or misalignment conditions
Both radial and axial load
Apply in the case of high load
Self-aligning (up to 2 °)
Remain stable in size up to 200 ° C operating temperature
Tapered Roller Bearings
With high axial and radial load carrying capacity
With little axial clearance of the bearing capacity with precise radial guide
Deep groove ball bearings
Mainly used for locating bearing, rarely as a fixed end bearings
Suitable for high-speed operation
You can also provide design with sealed
Greased deep groove ball bearings are suitable for applications with higher values of n x dm
Depending on the particular application, long-life lubrication is also possible, that is, without relubrication
Four-point contact ball bearings
The main use as a thrust bearing in the compressor, not to bear radial load
Can bear large axial load in both directions and can assume a smaller radial load
Because four-point contact ball bearing inner ring is split design, which makes it able to accommodate more rolling elements, thereby increasing the radial bearing capacity
Because this is a split inner ring bearing design: machined cage makes them more suitable for high-speed transfer case
With little axial clearance of the bearing capacity with precise radial guide
Compact bearing design - no separate locating bearing
