Discussion on the performance and application of stainless steel needle

2020-02-19 10:25:32

Deep groove ball bearing

The symbolic stainless steel cylinder needle is widely used for bearing axial load and double radial load. Suitable for high-speed operation and specified low noise, low vibration places with thick steel plate seal cover or silica gel seal ring, the sealed rolling bearing is filled with appropriate lubricating grease in advance, and the rolling bearing with stop ring or boss on the outside is very easy to radial precise positioning, which is also conducive to the installation in the casing. The specification of the large load type rolling bearing is the same as that of the standard rolling bearing, but a filling groove in the inner and outer ring increases the number of balls and the rated load.

Self aligning ball bearing

The self-aligning bearing of the needle bearing manufacturer is in the middle of the inner hole with two dovetail guide rails and the outer side with the dovetail guide rails as the curved surface, and the assembly line is provided with the rolling bearing of the drum type roller bearing. The refractive index management center of the outer dovetail guide rail surface is the same as the rolling bearing management center, so it has the same heart adjusting function as the full-automatic heart adjusting ball bearing. In case of tensile strain of shaft and casing, it can automatically adjust load and radial load in two directions. The axial load has large working capacity, which is suitable for the condition of heavy load and impact load. The nominal diameter of the inner hole is the tapered rolling bearing, which can be installed immediately. Or it shall be installed on the cylinder shaft with a tight set and a dismounting cylinder. The cage of needle rolling manufacturer shall be made of thick steel stamping die cage, acrylic resin molding cage and alloy copper turning cage.

Cylindrical roller bearing

Solid cylindrical roller bearing

The basic structure of the inner bore rolling bearing is the same as that of the Nu cylindrical roller bearing, but because the needle roller is selected, the volume can be reduced, and it can bear the large axial load. The mounting surface of the shaft with suitable precision and strength should be used as the dovetail guide surface.
