Bearings for ball screw support

The slewing ring is a large bearing that can withstand comprehensive loads, and can simultaneously withstand large axial and radial loads and overturning moments. Slewing ring bearings are generally equipped with mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, which can make the host design compact, easy to guide, and easy to maintain.

Slewing ring bearings have four-point contact ball bearings without gear, external gear and internal gear, double-row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller composite bearings. Series, four-point contact ball bearings have higher static load capacity, crossed cylindrical rollers have higher dynamic load capacity, and the pre-interference of crossed tapered roller bearings enables the bearing to have greater support rigidity and rotation accuracy.
The three-row cylindrical roller combined bearing leads to the height of the bearing due to the increase in load capacity, and various forces are borne by different raceways, so under the same force, the bearing diameter can be greatly reduced, so it has the characteristics of making the host more compact.
A slewing bearing with high load capacity. Slewing bearings are widely used in large-scale slewing devices of hoisting machinery, mining machinery, construction machinery, port machinery, marine machinery, and high-precision radar machinery and missile launchers. At the same time, it can also design, develop and produce various special structure slewing bearings according to the specific requirements of users.

Ball screw support bearing

In addition to the series with seals, there are also high-rigidity and high-function dedicated bearing series that enrich the product lineup.
1. High-rigidity and long life are realized by a high-function dedicated design that meets the requirements of the application.
2. The product with contact seal ring with high reliability and super dustproof design has also formed a series.
3. Improved operability.
