A unidirectional Roller pin Bearing is a Roller Bearing with a cylindrical Roller. Relative to its diameter, the drum is thin and long. This Bearing is called a one-way Roller pin Bearing. Although the cross-section is small, the Bearing has a high load-bearing capacity. One-way Roller pin Bearing equipped with slender Roller( Roller diameterD≤ 5mm,L/D≥ 2.5,L is the Roller length), so the radial structure is compact, the inner diameter and bearing capacity are the same. The unidirectional Roller pin Bearing is particularly suitable for support structures with limited radial mounting dimensions.
Depending on the application, one-way Roller pin Bearing without inner ring or Roller pin and cage assembly can be selected. At this time, the journal surface and the shell hole surface matched with the Bearing are directly used as the inner and outer rolling surfaces of the Bearing to ensure that the bearing capacity and operating performance are the same as the Bearing with ferrules, as well as the hardness, machining accuracy and surface quality of the shaft or Bearing seat hole. The raceway surface should be similar to the raceway of the Bearing ferrule. This one-way Roller pin Bearing can only carry radial loads.
The one-way Roller pin Bearing has a large load-bearing capacity and is suitable for supporting structures with limited installation dimensions. The journal surface is hardened to form a rolling surface. The Bearing is press-fitted in the Bearing seat hole and does not require axial positioning. Bearing should be filled with appropriate amount of grease before installation. Typically, they do not require relubrication after assembly. The one-way Roller pin Bearing is used to support the journal without extension. The sealing end face can bear small axial movement. Let's take a look at the dismantling of the one-way Roller pin Bearing.
The impact force generally acts on the inner ring of the Bearing. The impact force of the shielded machine room shall not act on the rolling elements and cages of the one-way Roller pin Bearing. This method is simple, but easy to damage the Bearing. When Bearing at the shaft end, use less than Bearing. Press the inner diameter copper rod or other soft metal material on the shaft end, and there is a cushion under the Bearing, which can be removed by beating with a hand hammer. When applying this method, attention should be paid to the correct placement of the shims and the correct focus.
The one-way Roller pin Bearing is equipped with a slender Roller, so the radial structure is compact, and its inner diameter and load-bearing capacity are the same as other types of Bearing. Particularly suitable for supporting structures with limited radial mounting dimensions. The one-way Roller pin is Bearing used in different occasions, and the machining accuracy and surface quality should be combined with the Bearing ferrule and application. The one-way Roller pin Bearing is a Bearing unit consisting of a centripetal Roller pin Bearing and a thrust Bearing component.
