combined bearing

Composite roller bearing is composed of axial and radial two roller bearing assembly, bearings reduce volume, simplifies the installation structure, thereby reducing the manufacturing cost. Composite roller bearing radial and axial bearing capacity are relatively large, good replaceability of components, more and more applications in a variety of door frame lift system.

Composite roller bearing mainly consists of the following parts:

1) head

Composite roller bearing is mounted welding, the specific way is to put a head and a hole plate welding, and then a door frame assembly;

2) main roller

The main roller combined bearings of main bearing, main bearing vertical load requirements with strong wear resistance corrosion resistance and impact resistance. At the same time the main roller can also be single direction bearing used alone, because it is itself a filled roller structure of roller bearing;

3) side roller

Side roller is a composite roller bearing in the main bearing, main bearing horizontal load, also has the very strong wear resistance corrosion resistance and impact resistance. Side roller is essentially a ring full needle roller bearing, roller bearing in the composite interior is through the mandrel and shaft together ;

4) cover

The main side roller shaft mounted together as a whole ;

Composite roller bearing assembly way :

Side roller through a mandrel mounted on the shaft, main roller sleeve in the shaft cover plate of the head tail was outside the nut is fixed, will eventually several part are fixed together.

We provide professional wide range of logistics conveyor rollers, composite bearings. Pipeline conveying composite rollers, forklifts, forklift wheel bearing MR series bolt roller curve roller, needle roller bearings and other packaging and printing machinery with a shaft roller bearing, track roller bearings, supporting roller bearing, such as in Inch series. The company is specialized in the production printing and packaging machinery with a shaft roller bearing. Composite roller bearings and related standard composite roller standard composite roller is divided into two kinds, one is repeatable lubricating type ZZ, bearing internal through oil passage ; the other is without duplication of lubricating 2RS type adjustable composite roller adjustable composite roller axial height can be adjusted for the use of the process for bearing generated by the abrasion clearance can to some extent to make up for it. It will also indirectly improving the service life of the bearing. 1 with the eccentric shaft adjustable composite roller bearing this side roller fixed in an eccentric pin shaft through an eccentric pin on the adjusting hole can be adjusted eccentric pin axis position adjustment is finished, but also through the positioning holes on the fixing. It can stay bearing appearance under the premise of realizing axial height change. 2 with screw adjustable composite roller such composite roller by adjusting the seat bottom thread hole position of the screw, so as to realize the height adjustment purposes. 3 with axial support adjustable composite roller such composite roller through axial support and the bearing block with different thickness of the gasket, so as to realize the height adjustment purposes. Overloading composite roller overloading composite roller look from the structure of adjustable composite roller. Is the large size of the adjustable composite roller used for load special occasions, such as more than 20 tons of lifting equipment. Overloading composite roller is divided axially support type and the eccentric shaft type two. 1 with an eccentric shaft overloading composite roller 2 with axial support overloading composite roller radial roller radial roller is a kind of dissimilation of composite roller, strictly speaking, is not because of the radial composite roller, roller without side roller, axial cannot rotate. Radial roller is also divided into reusable lubrication type ZZ and without duplication of lubricating 2RS type two. Welding plate of many customers to order composite roller bearing, need along with the matching welding plate together procurement. In order to facilitate the customers, I plant also provides the standard accessories. Composite roller bearing consists of two different directions of bearings installed components, reduce space and simplify the door frame structure, reduces the manufacturing cost. Axial and radial load bearing capacity are relatively large, good replaceability of components. The adjustable bearing can be regulated through the eccentric six corners or eccentric gear to adjust the core shaft position and to adjust the side roller axial dimension
