A four-bolt flange mounted assembly from the DODGE GT series pairs a cast iron housing with a self-aligning ball bearing insert. The insert locks onto the shaft through a Grip Tight cone, a design that speeds up installation and helps the bearing stay put under vibration. This unit supports rotating shafts on flat surfaces and is a common choice for power transmission in industrial settings.

Reading a GT code is straightforward. The letter F stands for a four-bolt flange. The number after B gives the shaft size in sixteenths of an inch. The M at the end identifies the sealing variant. So F4B-GT-20M describes a flange housing for a 20/16 inch shaft, which is 1 1/4", with M sealing. GT itself refers to the Grip Tight cone locking method. Codes in this series span a broad range of sizes.

Typical applications include belt conveyors, bucket elevators, mixers, mills, and process equipment in food, chemical, cement, and aggregate operations. The four-bolt flange mounts directly to sheet metal or structural steel, so no cylindrical seat needs to be machined. That makes the unit practical for packaging lines, aggregate processing plants, and similar installations.

When selecting a unit, confirm the shaft diameter and the load type. The GT series handles moderate radial and axial loads. For mounting, clean the shaft first, then position the insert and tighten the locking screws alternately with a torque wrench. Factory lubrication generally lasts a long time; in wet or dusty conditions, pick the right sealing and check alignment to keep stress off the bearing.

DODGE GT housings can replace other brands of four-bolt flange housings that use a locking cone insert, provided the flange dimensions, shaft diameter, and locking type match.
