What Is a Bearing Retainer Pin?
A bearing retainer pin is one of the parts used to secure a bearing.
The pin matches the size of the bearing in question and allows the bearing to be placed at the specified location with a screw while holding the width of the bearing.
Pins are sold separately from various types of bearings. When purchased separately from bearings, the pin should be selected by checking the size of the corresponding bearing.
A similar method of securing bearings is the use of bearing units.
The bearing unit is installed with bolts, etc., and used to support a load by inserting a shaft.
A bearing retainer pin and bearing units differ in the direction of fixation and the part to be fixed.
Uses of Bearing Retainer Pins
When a bearing is purchased as a stand-alone unit, it usually does not function unless the bearing outer diameter face is inserted into the housing inner diameter face, which is the default fit size, and then a shaft component is inserted into the bearing inner diameter face.
However, in many cases, directly mounting a bearing on a shaft or housing makes it very difficult to replace or otherwise repair the bearing.
To simplify that repair work, this holding pin is sometimes used.
Similarly, repair work can be simplified by using a bearing unit, although the fixing method is different.
Principle of Bearing Retainer Pins
The structure of the hold down pin is very simple. The shape of the hold down pin is similar to that of a bolt.
On the side opposite the threaded side of the bolt, a hexagonal hole or the like is machined so that it can be easily turned, like a hexagon socket head bolt. The outer diameter of this side is slightly larger than the inner diameter of the bearing, and when screwed in, it can hold the wide side of the bearing.
Next to the larger diameter than the bearing's inner diameter is the part where the bearing is inserted (the shaft).
Next to the bearing's bore dimension, there is a threaded section.
For example, if a bearing is built into the structure, base (highly rigid member), etc., by hard-fitting, etc., and a shaft of another part is inserted and used as a rotating shaft, the shaft and bearing can be fixed with retainer pins simply by drilling the specified tapped holes in the shaft.
In this case, the shaft can be removed by removing the holding pin, which simplifies repair work.
When using a bearing unit, the bearing unit can be placed simply by drilling a tapped hole anywhere on the Structure of, base (highly rigid member), etc., and the shaft can be installed.
When two bearing units are used to support a shaft with a loose fit, the shaft can be removed by removing a bolt from one of the bearing units, simplifying repair work.
