Bearings
Roller bearing The outer ring of the roller bearing adopts a full-filled cylindrical roller bearing with a thick outer ring wall. The outer diameter of the roller has a cylindrical shape and an arc shape, and can be matched with the raceway according to the design of the use occasion. With this outer ring, the roller can roll directly on the raceway and can withstand heavy loads and shock loads Model:MR.027

Assembly
Main wheel
The main roller is a composite roller shaft
The main of Chengzhong, mainly
Withstand vertical load, with
Strong abrasion resistance and corrosion resistance
And impact resistance. Can also be made
Single direction bearer used alone, because
For itself it's a full roll
Roller bearing of substructure;
Side rollerSide roller is a set of composite rolls
The second in the wheel, mainly
Withstand horizontal loads, the same
Has strong impact resistance and resistance
Grindability and corrosion resistance.
Side roller is full without inner ring
Needle design, replaced by a mandrel
Inner ring and shaft head joint bearing Cover
The function of the cover is to install
Side roller, shaft inside the shaft head
The main roller on the outside of the head is made of a nut and
The thread glue is fixed at the end of the shaft head
Part of the fixed part together
Together. The composite roller bearing consists of two bearings mounted in different directions, reducing space, simplifying the structure, and reducing the system.
Cause this. The radial and axial bearing capacity of the bearing is relatively large, and the accessories are highly replaceable. Adjustable bearing
The position of the mandrel can be adjusted by adjusting the eccentric outer hex or the eccentric gear to adjust the axial dimension of the side roller.
the goal of.
The structural bearing is assembled by the main and measuring rollers, and then used in conjunction with the connecting plate for welding, so the axial and radial bearings can be adopted.
Due to the very high load, we also have adjustable combined roller bearings according to the needs of different customers.
Hexagon mandrel, eccentric gear and shaft set screws to adjust the height of the roller to adjust the overall size of the bearing
Applied to different occasions
The composite roller bearing shell is divided according to the structural design: adjustable and non-adjustable.
Adjustable can be divided into: gear adjustment, hex adjustment, nut adjustment.
The gear is adjusted so that the inner end of the side roller inner ring (ie, the mandrel) is processed into an eccentric gear shape, and the mandrel and the shaft joint are connected.
Also designed as a gear, the entire composite roll is adjusted by adjusting the eccentric amount of the gear to adjust the amount of protrusion of the side roller.
The height of the wheel is generally used for small tonnage forklifts, material hoists, production flow lines, and lifting systems.
Hexagonal eccentricity adjustment and gear adjustment are the same principle, the tail gear is hexagonal eccentricity, and the hexagon is adjusted by
To adjust the overall height of the composite roller, the hexagonal adjustment composite roller is generally used for load, compared to gear adjustment.
Large equipment with high stability, container forklifts, port machinery, steel sheet metal equipment, shield machines, etc.
Confidential equipment.
The nut adjustment is that the side roller is mounted on the pedestal and the inside of the shaft head is adjusted by two setscrews on the head of the shaft head.
The amount of the yoke of the pedestal (side roller) is used to adjust the overall height of the bearing. Compared to the above two methods, the nut adjustment
For the latest design, it is not necessary to disassemble the bearing, the adjustment is simple and convenient, and it is often used for the door bracket of the 1-45T forklift, lifting system,
Equipment such as production lines.
The non-adjustable side roller inner ring (mandrel) is cylindrical and connected to the shaft head, which can be rotated, compared to the adjustable type.
The structure is suitable for precision, functionally stable equipment that does not require adjustment and is relatively inexpensive.
