The ZKLF screw support bearing is a bearing with a 60° contact angle on the outer ring. This type of bearing can withstand high axial and radial forces. For bearings with the same inner diameter, their cross-sectional dimensions are larger, so the basic load rating is higher. The outer ring of the ZKLF screw support bearing has a bolt mounting hole, which can be directly installed on the side of the bearing seat. There is a grease injection hole on the outer diameter surface and the side surface, and grease can be replenished as needed. When grease is not required, a blind bolt can be installed to prevent foreign matter from entering. In addition, the outer diameter surface of the outer ring has a disassembly groove to facilitate bearing disassembly.
The ZKLF series bearings are equivalent to the structure of the ZKLN series bearings, except that the outer ring is thicker and has through holes for mounting bolts. It is directly installed on the associated components by bolts, which simplifies the structure and installation process. In order to enable relubrication when necessary, there are M6 threaded holes for grease injection on one end face and the outer diameter surface of the bearing. These holes are blocked by countersunk (tightening) screws when the bearing leaves the factory. The end face with threaded holes should be installed against the bed surface.
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 data 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.
If you have any questions about products and services, please contact the company's service department directly.
