Positioning / lubrication bore

For error-free positioning of the lubrication bore of the bearing to the lubrication hole in the machine housing, the AXRY-NGS bearings have a so-called locating pin hole (1) on the outer ring.

The following sketch shows the fastening screw (4) and the bearing mark on the inner ring lying on top. The axial washer is installed on the table.
The positioning hole (1) is offset by half a pitch division to the fixing hole (3) and by one whole pitch division to the lubrication bore (2).

The pitch divisions in the individual bearings are listed in the product data sheet in the table Fixing holes.
The diameter d_PB of the positioning hole of the bearing outer ring is designed slightly larger than the recommended pin diameter d_ST (see table).

Positioning hole design for the AXRY-NGS

Secure the positioning pins appropriately during assembly. The pins must be reliably prevented from dropping out in operation.
