UCF Four-Bolt Flanged Units(ucf four-bolt flanged bearings): Hebei Naimei Bearing Co., Ltd. produces kind of pillow block bearings. Ucf Four-Bolt Flanged Units is one of the main product. Pillow block, also know as a plumer block or bearing housing, is a pedestal used to provide support for a rotating shaft with the help of compatible bearings and various accessories. Housing material for pillow block is typically made of cast iron or cast steel.
The fundamental application is to mount bearings safely enabling their outer ring to be stationary while allowing rotation of the inner ring. The housing is bolted to a foundation through the holes in the base. Bearing housings are either split type or unsplit type. Split type housings are usually two piece housings where the cap and base can be detached, while certain series are one single piece housings. Various seals are provided to prevent dust and other contaminants from entering the housing. Thus the housing provides a clean environment for the expensive bearings to freely rotate, hence increasing their performance and duty cycle.

Feature
1. Long service life with reliable seal and without frequent main tenance
2. Pressure loss
    Too much pressure loss will bring increased cost of correlative energy
     Butterfly valve have flow characteristics three times better than globe valve,and about 75%
     of a same size gate valve
3. Multi-Function
   Butterfly valve can be used for on/off service and throttling,They are superior in Multi-function
   as compared to gate or globe valves.Butterfly valve can be widely used in chemical field due
   to trim options and choice of elastomeric liner.
4.Weight
   Butterfly valve have feature of light in weight and small in size,for example, weight and size ofÂ
   a 10'' butterfly valve are 1/9 and 1/6 of a 10'' gate valve.So butterfly valve is easy to install andÂ
   save cost of piping system.
5.Bubble Tight
   Butterfly valve with resilient seat design can be bubble tight as compared to metal seated gate
   or globe valves.
6.Easy of operation
  Butterfly valve offer 90-degree open to close.
7. Butterfly valves is approximate 35-40% cost of a same size gate valve. Also lowÂ
   installed cost than gate valve.
8.Maintenance
   Properly installed butterfly valves are self cleaning and are less susceptible to failure due toÂ
   trash material in pipe.
9.Delivery Time:25 days after order conformed.
