The DODGE D-Lok series 4-bolt flange bearing is a mounted unit built around a cast iron housing and an eccentric locking insert ball bearing. Four bolts hold the flange to a flat surface while the shaft runs perpendicular to the mounting plane. It supports rotating shafts on conveying and transmission equipment, and alignment is straightforward.
Reading a D-Lok code is done in blocks. The F stands for 4-bolt flange, 4B identifies the housing type, DLM marks the insert series with D-Lok locking, the middle number gives the nominal shaft size, and NL is a sealing or configuration variant. Compare F4B-DLM-204-NL with F4B-DLM-208-NL: only the central number moves, and that number sets the size. Send the full code so the part is identified without ambiguity.
Typical installations include belt conveyors, bucket elevators, mixers, blowers and packaging lines in food, beverage, cement, aggregate and water treatment plants. The four-bolt flange mounts onto existing sheet metal or structure, and the unit handles moderate radial and axial loads with simple alignment.
Selection comes down to shaft diameter, load type and the environment. The NL seal keeps out dust and moisture; where pressure washing or abrasives are present, extra protection is worth considering. D-Lok eccentric locking is set by turning the collar in the direction of shaft rotation. Before tightening the four bolts, check flange alignment, then confirm axial play and lubricate with a compatible grease.
DODGE is a reference brand in mounted bearings, and MR supplies it. Interchangeability with other brands is set by shaft diameter, hole spacing and locking type, not by the code alone, so a compatible alternative with the same mounting dimensions can be reviewed. Send the dimensions or the code and we will point to the option that fits best. MR also manufactures split pillow block housings, roller chains and sheaves.

Frequently asked questions
- How is the shaft size shown in a DODGE D-Lok bearing code?
- The central number of the code gives the nominal shaft size. In F4B-DLM-204-NL it corresponds to a 20 mm shaft or its inch equivalent, depending on the series. Send the complete code and we will confirm the exact size.
- What does the NL suffix indicate?
- NL identifies a sealing or insert configuration variant in the D-Lok series. It does not change the shaft diameter or the hole spacing. If your equipment uses a different ending, send us the code and we will review the alternative.
- Can another brand's bearing replace it?
- Yes, when shaft diameter, flange hole spacing and locking type match. The code alone does not define interchangeability. Send the measurements or the original code and we will indicate the compatible option.
