DLR Series Straight Lubricated Angular Contact Ball Bearings with Lubrication Holes

Direct Lube Super precision angular contact ball bearings

In order easy to lubricate effectively, our company provides DLR series straight lubrication angular contact ball bearings with lubrication holes and groove on outer ring. The design have two groove on the outer ring, two lubrication holes in each groove, and two outer grooves with O-rings in the outer ring. The DLR series can directly supply oil from the outer ring to prevent the lubricating oil leaking from the bearing and the bearing seat hole mounting surface to improving the reliability of lubrication. Supply oil through the outer ring oil holes,the spacers will not necessary, and the spindle space can be compactly. In this way, the spindle can running more freely, thereby improving the processing performance.

When running at high speed, the method of supplying oil from the side face may cause the bearing to stick because the lubricating oil is blocked by the air curtain. The DLR series makes reliable lubrication possible by supplying oil from the outer ring to the inside of the bearing. The O-ring prevents oil leakage from the outer diameter surface of the bearing. Because there is no need for an oil supply spacer, the spacer width can be shortened, the spindle can be made compact, the span of the bearing from the shaft end can also be shortened, the spindle length is shortened, the critical speed is increased, and the natural frequency is also increased to a certain extent. In addition, the two O-rings in the outer ring ensure that the through holes in the housing are firmly sealed.The two O-rings in the outer ring ensure that the through holes in the housing are firmly sealed. This means that any suitable application can be selected according to the specific working conditions. Because there is no injection nozzle between the bearings, the spindle design can be very compact. As the size of the DLR series angular contact ball bearing is the same as that of the commonly used angular contact ball bearing, it is easier to make the spindle assembly as a module for various spindle series. Improve cost-effectiveness for spindle manufacturers.

Our company has professional sales and technical engineers who are responsible for providing users with technical consultation, technical services and product technical training on precision bearing materials and installation and use. Perfect pre-sales, in-sales and after-sales services constitute a guarantee system for high-quality services, providing users with reliable quality bearing products and creating excellent user experience and rich benefits for every customer.
