Characteristics of deep groove ball bearings

Each ferrule of the deep groove ball bearing has a continuous groove type raceway whose cross section is approximately one third of the circumference of the equator of the ball. Deep groove ball bearings are mainly used to withstand radial loads and also withstand certain axial loads. When the radial clearance of the bearing is increased, it has the property of an angular contact ball bearing and can withstand the axial load alternating in two directions. Compared with other types of bearings of …

Structural features of tapered roller bearings

The type of tapered roller bearings is 30,000, and the tapered roller bearings are separate bearings. Under normal circumstances, especially in the size range of GB/T307.1-94 "Rolling bearing radial bearing tolerance", the tapered roller bearing outer ring and the inner component are 100% interchangeably usable. The angle of the outer ring and the outer race diameter have been standardized as the outer dimensions. Changes are not allowed at the time of design and manufacture. So that th…

Structure and performance characteristics of double row tapered roller bearings :

Double row tapered roller bearings have many structures, the largest one is 35000 type, there is a double raceway outer ring and two inner rings, and there is a between two inner rings. The spacer can be adjusted by changing the thickness of the spacer. These bearings can withstand radial loads while being able to withstand biaxial axial loads, limiting axial displacement of the shaft and housing over the axial clearance of the bearing.This article from QIBR official website, for reproduced, plea…

Oil-free bearing assembly and disassembly

The size of the force should be smooth and uniform, and it is not suitable for impact. This requires the use of oil pressure or a tool that can apply a smooth pulling force or pressure. When it is necessary to use hammering, it must also pass through a soft sleeve such as a copper sleeve. Buffering, the tapping force may be gentle.This article is from QIBR official website www.qibr.com reproduced please indicate!

High quality machine tool bearings

The accuracy of the bearing used on the machine tool spindle should be ISOP5 or above (P5 or P4 is the ISO accuracy level, usually from low to high (P0, P6, P5, P4, P2), and for high speed CNC machine tools, machining centers, etc. For high-precision machine tool spindle bearings, ISOP4 or higher accuracy is required. Spindle bearings include angular contact ball bearings, tapered roller bearings, and cylindrical roller bearings.This article is from QIBR official website www.qibr.com reproduced p…
