A ZUCNFL unit is a flange-mounted bearing assembly that pairs a cast iron housing with an insert bearing already fitted and greased at the factory. It bolts to a flat surface through two holes and carries a shaft that runs parallel to that surface, which makes it a practical choice for machinery frames, panels and structural steel.
Reading the code helps you order the right size the first time. The letters ZUCNFL mark the two-bolt flange housing family with an insert bearing, and the digits after them give the shaft diameter in millimeters: ZUCNFL204 fits a 20 mm shaft, ZUCNFL205 a 25 mm shaft and ZUCNFL206 a 30 mm shaft. When the number carries a hyphenated suffix, the shaft size is in inches instead: ZUCNFL204-12 is built for a 3/4 inch shaft, ZUCNFL205-16 for 1 inch and ZUCNFL206-18 for 1-1/8 inch.
You will find these units on conveyors, belt drives, elevators, mixers, fans and process lines where the shaft sits parallel to sheet metal or a frame. Typical settings include food processing, cement, grain handling, tanneries and metalworking shops. The two-bolt flange mounts on flat surfaces with matching hole centers, and the insert absorbs small mounting misalignments, so the unit suits moderate shaft speeds under radial load with some axial load as well.
Before ordering, confirm three things: shaft diameter, insert locking style (set screw, eccentric collar or adapter) and seal type. Standard units use contact seals that hold grease in and keep dust out. For washdown areas or very fine dust, extra protection is worth considering. At installation, set the flange on a clean, flat surface, tighten the bolts in a cross pattern and turn the shaft by hand to confirm it rotates freely. The insert arrives greased; relubrication afterward follows the duty cycle.
Mounted units can be swapped between manufacturers when shaft diameter, hole spacing, bolt diameter and center height line up. Each brand applies its own naming system, but the standardized dimensions usually allow a direct replacement. If you are holding another maker's number or a part you cannot identify, send the key dimensions and we will point you to the equivalent.

Frequently asked questions
- What does the hyphenated suffix in ZUCNFL204-12 mean?
- It tells you the shaft size is given in inches. ZUCNFL204-12 fits a 3/4 inch shaft, whereas ZUCNFL204 without a hyphen is made for a 20 mm shaft. Measuring the actual shaft before ordering is always the safest step.
- Can a ZUCNFL housing from another brand be replaced with an NTN one?
- Often yes, provided the shaft diameter, flange hole spacing, bolt diameter and center height are the same. These units follow standardized dimensions, so cross-brand replacement is common. Share the dimensions or the part number and we will confirm the equivalent.
- How is a ZUCNFL housing with insert bearing lubricated?
- The insert comes greased from the factory. Once in service, grease is added through the unit's grease channel where one is provided, using a grease suited to the application. How often depends on speed, load and surroundings. Shorten the intervals in dusty or damp locations and inspect the seal.
