The DLR series angular contact ball bearings produced by MONTON directly supply oil through the outer ring of the bearing, improving the reliability of bearing lubrication and achieving compact spindle design.

Their characteristics are as follows:

1. High reliability of fuel supply

When the bearing speed is high, the lubricating oil on the side is blocked by the air curtain wall, which hinders lubrication; Directly supplying oil from the outer ring to the inside of the bearing can achieve a stable lubrication environment, and prevent oil leakage from the outer diameter surface of the bearing through the O-ring.

2. The spindle design is more compact

Directly supplying oil from the outer ring oil supply hole, without the need for an oil supply spacer, shortens the spacer width, and achieves spindle compactness. Due to the shortened length of the shaft, the span of the main shaft bearings is shortened, and the natural frequency of the main shaft is further increased.
