ROLLER PARTS

BEARING HOUSING
Rexroller Bearing housing are produced by the technology of stamping & pressing. Till now we have three types of bearing housings, which have their own specific respectively, thus they could satisfy the requirements of different customers and environmental requirements of different industries.

BEARING
Rexroller Bearing are applying with large clearance, Deep groove ball bearings, which can protect and guarantee the rollers with the ideal static and dynamic balance Bearings either with double dust proof cover or with double Labyrinth ring will ensure rollers running smoothly to the maximum extend. Currently the bearing we used is FAG and SKF or as per required.

SEALING SYSTEM
Rexroller use the multiple layer seal, and rush into lithium lubricating grease in the seal. The bearing oil loading is about 2/3-3/4 of the bearing clearance, The clearance between the seal rings are fully loaded. This way guarantees the enclosed and the compact endless of the seals and achieved the effectiveness of dust proof, waterproof and the bearing protection.

RETURN ROLLER

Return roller are designed to support the return belt. The selection of the return idler type is influenced by the strength, stiffness, and weight of the belt.

Return roller are installed on the unloaded branch to support the conveyor belt on the branch. In the common layout the use of V-shaped or reverse V-shaped support in the lower unloaded section is beneficial to restrain the deviation of the conveyor belt.

Besides the rubber disc types A and B return idlers can be equipped with polyurethane discs. Tailor-made support ring assembly types are also available.

Rexrollers are used for belts that are clean and non-sticky. It is also available with rubber lagging (5mm or 10mm) and can be used as an impact roller. They are also used on both sides of the pressing guide bracket and as a counter idler for the cleaner.

RETURN A TYPE ROLLER

Distance between supporting is equal. The Roller is for high stiff belts with short distance between idlers.

RETURN A(II) TYPE ROLLER

The support ring is more closely distributed at both ends of the roller. The support ring makes the outer area of the belt tightly packed. This support ring arrangement reduces the lateral drift of the conveyor belt and ensures the smooth running of the belt.

GARLAND – ROLLER

Rexrollers roller replace traditional idler and brackets. The idler are connected to each other with flexible links and fixed to the conveyor frame with suspension links which allow free movement in the direction of belt travel.

Rexroller Rollers garland idler roller spread the load over more idler. Thus also the belt profile changes and the belt load becomes steadier. The total quantity of the steel in conveyor frame can often be considerably reduced and the frames simplified.

When conveying heavy item, with the help of garland idlers the pressures against the belt and idlers can be reduced. The life of the belt and idlers increase and thus a better economy is achieved.

Rexrollers provide four different hanging buckles. By lifting the idler set from the hook, the wreath idler set can be easily replaced.

IDLER ROLLER BRACKET

Rexline Engineering bracket has a good steel structure, which provides a high load-bearing capacity.

The roller is fixed to the bracket by screws or hanging buckles. When the side idler is tilted forward, the Rexline Engineering bracket can stabilized the direction of the belt.

The surface of the bracket is processed by ho-dip galvanizing. Hot-dip galvanizing provides good corrosion protection and does not required any special precautions during transportation and handling.

The main bracket is made of sheet metal and can bear the maximum weight. The narrow shape of the top edge of the mechanism effectively prevents the accumulation of cleaning materials.
