The SNR UCF216 80 mm bearing unit is supplied by simmering.pl for machinery service, workshops, maintenance departments and industrial customers throughout Poland and the European Union.
SNR UCF216 80 mm is a complete self-aligning flange bearing unit consisting of a UC216 insert bearing and a four-bolt F216 cast iron housing. It is designed for an 80 mm shaft and uses direct set-screw locking on the inner ring. Key mounting dimensions include 165 mm mounting-hole spacing and 57 mm housing height. The unit is suitable for conveyors, industrial drives, agricultural machinery and other applications requiring a ready-to-install flange-mounted shaft support.
What Is the SNR UCF216?
SNR UCF216 is a complete self-aligning flange bearing unit for an 80 mm shaft. It combines a UC216 insert bearing with a four-bolt F216 flange housing. The bearing is secured directly to the shaft by set screws in the extended inner ring. NTN-SNR catalogue data confirms the 80 mm shaft diameter, 165 mm mounting-hole spacing and 57 mm housing height for this unit.

What Does UCF216 Mean?
The designation identifies the construction of the complete mounted bearing unit:
UC - insert bearing with extended inner ring and set-screw shaft locking
F - square flange housing
216 - bearing and housing size
For the UCF216 execution, the nominal shaft diameter is 80 mm.
80 mm Shaft Mounting
The UC216 insert bearing is mounted directly onto a cylindrical 80 mm shaft.
The extended inner ring is secured to the shaft by set screws. This provides a simple and direct shaft-locking method without the use of an adapter sleeve.
This is one of the key differences between the UCF and UKF bearing unit designs.
UCF216 vs UKF216H
Although both units belong to the F216 housing family, they use different bearing inserts and shaft-mounting systems.
UCF216: 80 mm shaft, UC216 insert, set-screw locking
UKF216H: 70 mm shaft, tapered-bore UK insert, adapter sleeve mounting
The two units should therefore not be considered direct replacements.
Self-Aligning Design
The insert bearing has a spherical outer surface that operates in the corresponding spherical seating of the housing.
This allows the bearing unit to compensate for a limited amount of initial misalignment between the shaft and housing.
The self-aligning feature does not replace correct machine alignment, but it helps accommodate small installation errors.
F216 Flange Housing
The F216 is a square flange housing with four mounting points.
Key mounting dimensions include:
Overall housing size: approx. 208 mm
Mounting-hole spacing: 165 mm
Housing height: 57 mm
Shaft diameter: 80 mm
These dimensions should be checked when replacing a complete mounted unit, because shaft diameter alone is not sufficient to confirm compatibility.
Typical Applications
The SNR UCF216 80 mm can be used in appropriately designed:
- conveyor systems,
- agricultural machinery,
- production equipment,
- industrial drives,
- material handling systems,
- processing machinery,
- fans,
- mechanical transmission equipment,
- industrial maintenance applications.
Final selection should consider shaft diameter, load, speed, temperature, lubrication and contamination conditions.
How to Select a Replacement for SNR UCF216
Verify:
Manufacturer: SNR
Designation: UCF216
Shaft diameter: 80 mm
Insert bearing: UC216
Housing: F216
Shaft locking: Set screws
Number of mounting holes: 4
Mounting-hole spacing: 165 mm
Housing height: 57 mm
Matching only the F216 housing designation does not confirm that the complete bearing unit is identical.
FAQ - Technical Questions
What shaft diameter is the SNR UCF216 designed for?
The UCF216 is designed for an 80 mm shaft.
Which bearing insert is used in UCF216?
The unit uses a UC216 insert bearing.
How is the bearing secured to the shaft?
The UC216 insert is secured directly to the shaft using set screws.
What is the mounting-hole spacing?
The centre distance between mounting holes is 165 mm.
What is the housing height?
The housing height is 57 mm.
Frequently Asked Questions from Engineers and Maintenance Technicians
Is UCF216 self-aligning?
Yes. The spherical outer surface of the insert bearing allows limited self-alignment within the housing.
Does UCF216 require an adapter sleeve?
No. The UC216 insert is mounted directly on the 80 mm shaft and locked by set screws.
Can the UC216 insert be replaced separately?
Yes, provided the replacement insert is compatible with the F216 housing.
Are UCF216 and UKF216H interchangeable?
No. UCF216 uses an 80 mm shaft and set-screw locking, while UKF216H uses a 70 mm shaft and adapter sleeve mounting.
Is the F216 designation enough when ordering a replacement?
No. The housing designation, insert bearing, shaft diameter and locking method should all be verified.
