This DODGE D-Lok series mounted unit pairs a cast iron 4-bolt flange housing with an insert ball bearing that locks onto the shaft by eccentric collar. It supports rotating shafts on flat surfaces where alignment stays fixed and mounting or removal needs to be straightforward.

Reading the D-Lok code helps you order the right replacement. The first letter stands for housing style: F means a 4-bolt flange. The digits after the hyphen give the nominal shaft size in millimeters, so F4B-DL-20M fits a 20 mm shaft and F4B-DL-25M fits a 25 mm shaft. DL marks the D-Lok series with eccentric locking collar, and the trailing M identifies the housing and sealing version.

Typical applications include belt conveyors, bucket elevators, mixers, mills, centrifugal pumps and other process equipment. The shaft sits on a vertical flange or a sheet metal structure, and the four-bolt pattern mounts on flat surfaces with aligned holes. The unit handles moderate radial and axial loads.

When selecting, confirm the shaft diameter and the locking method your equipment uses. D-Lok units lock by turning the eccentric collar in the direction of shaft rotation. Check the sealing arrangement as well, since the housing may use a lip seal or a higher-protection seal depending on the environment. During installation, align the flange holes, tighten bolts in a cross pattern and lubricate the insert before start-up. Careful alignment supports bearing life.

Interchangeability between mounted bearing housing brands depends on shaft diameter, housing type (4-bolt flange) and locking system. Matching size alone is not enough: verify hole spacing, hole diameter and center height. A unit with similar technical characteristics can serve as a replacement. Send the part number or measurements by WhatsApp and we will point you to a compatible alternative.
