Precautions for installation of needle roller bearings

Precautions for installation of needle roller bearings

2022-03-22

The installation of full complement needle roller bearings is usually carried out with auxiliary sleeves. At this time, the auxiliary roller or the auxiliary sleeve supports the needle roller so that the needle roller does not fall out, and the journal lifts the needle roller with its own chamfer. As the needle bearing slowly moves inward on the journal, the auxiliary roller Or the auxiliary sleeve will slowly withdraw until it is installed to the working position.

How thrust ball bearings work

How thrust ball bearings work

2022-03-22

Thrust ball bearing is a separable bearing, the shaft ring and seat ring can be separated from the cage and steel ball assembly. The shaft ring is a ring matching the shaft, and the seat ring is a ring matching the bearing seat hole, and there is a gap between the shaft and the shaft; thrust ball bearings can only bear axial loads, and one-way thrust ball bearings can only bear axial loads. For the axial load in one direction, the two-way thrust ball bearing can bear the axial load in two directions; the thrust ball bearing cannot limit the radial displacement of the shaft, and the limit speed is very low, and the one-way thrust ball bearing can limit one of the shaft and the housing Axial displacement in one direction, two-way bearings can limit axial displacement in two directions.

Precautions for use of deep groove ball bearings

Precautions for use of deep groove ball bearings

2022-03-22

For deep groove ball bearings, if the bearing load is too small during operation, sliding will occur between the ball and the raceway, which will cause abrasions. Especially large deep groove ball bearings with high ball and cage weights have this tendency. In many cases, bearings will rust. There are many reasons for bearing corrosion. The most common factors in our daily life are the following:

Product Features of Cylindrical Roller Bearings

Product Features of Cylindrical Roller Bearings

2022-03-22

Cylindrical roller bearing raceways and rolling elements are geometrically shaped. After the improved design, it has a higher bearing capacity. The new structural design of the rib and the end face of the roller not only improves the axial bearing capacity of the bearing, but also improves the lubrication conditions in the contact area between the end face of the roller and the rib, and improves the bearing capacity. Bearing performance.

The use of tapered roller bearings

The use of tapered roller bearings

2022-03-22

Tapered roller bearings mainly bear combined radial and axial loads. The load capacity of the bearing depends on the raceway angle of the outer ring, the greater the angle, the greater the load capacity. This type of bearing is a separable bearing, which is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearance of double-row and four-row tapered roller bearings has been given according to user requirements when the product leaves the factory, and no user adjustment is required.

What is a spherical roller bearing?

What is a spherical roller bearing?

2022-03-22

Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also bear axial loads in either direction. It has high radial load capacity, especially suitable for working under heavy load or vibration load, but it cannot bear pure axial load. The raceway of the outer ring of this type of bearing is spherical, so its self-aligning performance is good, and it can compensate the coaxiality error.
