HT200 HT250 Plummer Block Bearing , Adjustable Split Housing Pillow Block Bearings

What are the advantages of the split bearing housing and the flange bearing housing?

Split type bearing housing, plummer block bearing housing.
The dissection bearing housing is the most common installation component, the product design level is divided, the cover and the bottom can be broken up, so the equipment installation and debugging and maintenance.

It's also very convenient. For the demanding equipment, the split type bearing housing is also designed for two kinds of stud holes. These are the main components
Bear the radial load directly under the inner base. Used for demanding and high equipment. This bearing housing can be adapted to a wide range of dimensions and can withstand high load.

The heavy bearing pedestal adopts grey cast iron for its standard configuration, and provides the choice of flexibility in sealing and lubrication, available grease or oil.

The applicable equipment includes: the belt type processing equipment in the steel mill, the fan and blower, the wool cloth roller and the drying of the paper industry.
Drying cylinder, ore procegssing industry used crusher, hammer type grinder and kiln. The standard dissection bearing housing is made from cast iron, cast steel, ductile iron.

The split type bearing pedestal can choose LEP/LOR three ring oil seal, contact oil seal, corner oil seal and end cover. Work the shaft and bearing surface.

The clearance is small so as to prevent the contamination from entering and retaining the grease or oil. This ensures that the bearing and bearing pedestal can last longer.
In addition to the large equipment, the SKF split type bearing seat has three forms SAFSAW and SDAF. The fourth is called the extension series, which is designed to meet the requirements of large equipment, the requirements include axial dimensions between 250 and 500mm.

Installation - cylinder mounting

The cylinder hole installation includes the interference fit to fit a straight hole bearing into a cylindrical shaft. This assembly method is especially suitable for high speed setting to prepare.

In the cylinder hole installation, the shaft must have precise tolerances at the bearing seat and the thread on the nut must be machined, it is often necessary to heat the inner ring.

Installation - taper hole mounting

When the adapter is installed, conical bore bearings are mounted on the cylinder shaft through a tapered adapter. The adapter installation is considered generic
In this method, the bearing is loaded on the shaft. The shaft seat does not need to be machined like the precision tolerances required for cylindrical holes.
And this installation method does not require heating bearings. In addition, it is also quite convenient to use conical adapters when disassembling. The total installed by the adapter

The body cost is also less than the cylinder hole installation.

The positioning ring is fixed in the bearing seat, also known as the "fixed" bearing. Other terms "fixed or floating" or more "positioning or not positioning.

Flange bearing seat

There are many types of flange bearings: square, round, diamond, convex, convex, circular, and sliding block. 
The mounting hole of type flange bearing seat has four holes, three holes, two holes and no mounting holes. The sliding-block type with no mounting hole is two sliders up and down slot.

You can move back and forth on the rack. Therefore, it is best to adjust the distance between axes. The axis of the machine can be moved in operation multi-purpose on belt, chain and other transmission shafts.

The flange bearing seat is the most typical and most commonly used type, which is applicable to all gearing and the shaft and the mounting plane parallel to the machine when using full strength and steel.
