UCFC 214 CT 70 mm - Round Four-Bolt Flange Bearing Unit

Product Description

UCFC 214 CT is a round four-bolt flange bearing unit designed to support a rotating shaft with a nominal diameter of 70 mm. The product belongs to the UCFC200 series and carries the CT brand designation. Its standard construction combines a UC214 insert ball bearing with an FC214 round flange housing featuring a locating spigot for accurate positioning in a prepared machine mounting surface.

The UCFC 214 bearing unit is designed for industrial shaft support applications requiring secure flange mounting, accommodation of minor shaft misalignment and convenient installation.

Unlike a conventional deep groove ball bearing supplied as an individual component, UCFC 214 is a complete mounted bearing unit incorporating both a bearing insert and a housing.

Technical Specifications - UCFC 214 CT

The dimensional values above describe the standard UCFC214 configuration commonly listed in mounted bearing catalogues.

The exact dimensions of the CT-manufactured version should be verified against the manufacturer's drawing or the actual product before installation.

Dynamic and static load ratings, bearing mass, permissible speed and operating temperature have not been assigned from other manufacturers' catalogues because these values may differ between specific executions.

What Does UCFC 214 CT Mean?

The designation UCFC 214 CT identifies a complete mounted bearing unit.

UC - Insert Ball Bearing

UC identifies an insert ball bearing featuring an extended inner ring and a spherical outer surface.

The inner ring is typically secured to the shaft using set screws.

The spherical outer surface allows the bearing insert to align within the corresponding housing seat.

FC - Round Flange Housing

FC identifies a round flange housing with a locating spigot.

This housing design provides a four-bolt mounting arrangement and a centring feature for positioning the bearing unit in a suitable machine structure.

2 - Bearing Unit Series

The digit 2 identifies the UC200 dimensional series.

14 - Bore Size Code

The bore code 14 corresponds to a nominal shaft diameter of 70 mm.

CT - Brand Designation

CT identifies the commercial brand of the supplied bearing unit.

The complete designation UCFC 214 CT should be preserved when ordering or identifying the product.

Construction and Operating Principle

The UCFC 214 CT bearing unit combines a self-aligning insert ball bearing with a round flange housing.

Its construction provides shaft support, mounting flexibility and accommodation of minor alignment deviations.

UC214 Insert Ball Bearing

The UC214 bearing insert has an extended inner ring and a spherical outer surface.

The spherical geometry allows the insert to adjust its position within the corresponding housing seat, helping compensate for minor initial misalignment between the shaft and housing.

This self-aligning capability does not eliminate the need for correct machine alignment.

FC214 Round Flange Housing

The FC214 housing has a circular flange with four mounting holes.

A locating spigot on the mounting side helps position the unit in a corresponding recess.

This arrangement provides a defined mounting position and assists in transmitting loads between the bearing housing and the supporting structure.

Rolling Elements and Load Transmission

The bearing insert uses balls running between inner and outer raceways.

The bearing supports radial loads and can accommodate axial loads within the limits of the insert bearing design.

The permissible load depends on the exact bearing construction, operating conditions and housing strength.

Shaft Locking System

The UC214 insert is typically secured to the shaft using set screws located in the extended inner ring.

Correct shaft diameter, surface condition and tightening torque are important for reliable mounting.

Sealing and Lubrication

UCFC bearing units commonly incorporate sealed bearing inserts and provisions for grease lubrication.

However, the exact seal design, grease specification and relubrication arrangement must be confirmed for the specific CT version.

UCFC 214 CT vs Other Bearing Unit Configurations

These designations describe different bearing and housing configurations.

They should not be considered automatically interchangeable.

UCFC214 vs UCF214

UCFC214 uses a round flange housing with a locating spigot.

UCF214 uses a square flange housing.

Although both configurations may accommodate the same nominal shaft diameter, their mounting dimensions and installation requirements differ.

UCFC214 vs UCFL214

UCFC214 has a round four-bolt flange housing.

UCFL214 uses an oval two-bolt flange housing.

The two configurations have different mounting arrangements and are not direct replacements without modification or verification.

UCFC214 vs UC214

UC214 identifies the bearing insert only.

UCFC214 identifies the complete bearing unit, including the insert and round flange housing.

This distinction is important when ordering replacement components.

Alternative Designations and Search References

The bearing unit may be identified using the following designation variants:

• UCFC 214 CT

• CT UCFC 214

• UCFC214 CT

Typical Applications

Round flange bearing units of the UCFC214 type are used in industrial machinery requiring reliable shaft support and flange mounting.

Typical applications of this bearing unit design include:

• Industrial conveyor systems.

• Manufacturing machinery.

• Material handling equipment.

• Mechanical drive systems.

• Agricultural machinery.

• Rotating shaft support assemblies.

• Industrial processing equipment.

These are general applications of UCFC-type bearing units, not confirmed OEM applications of the exact CT product.

Final suitability depends on shaft loads, rotational speed, installation geometry, lubrication and environmental conditions.

Installation, Lubrication and Maintenance

Preparation Before Installation

Clean the shaft and housing mounting surface.

Inspect the shaft for burrs, corrosion or damage that could prevent correct positioning.

Housing Installation

Position the locating spigot in the corresponding mounting recess.

Ensure that the flange is correctly seated against the supporting surface.

Tighten the mounting bolts evenly according to the machine manufacturer's specifications.

Shaft Locking

After positioning the bearing unit, secure the extended inner ring to the shaft using the set screws.

The correct tightening torque should be obtained from the manufacturer documentation for the supplied insert.

Bearing Alignment

The spherical outer surface of the UC214 insert allows minor alignment compensation within the housing.

However, excessive shaft misalignment may increase bearing loads and reduce service life.

Lubrication

Use the grease and lubrication procedure specified for the particular CT bearing unit.

Relubrication intervals should be determined according to operating speed, load, temperature and environmental contamination.

Storage

Store the bearing unit in a clean, dry environment, preferably in its original packaging.

Protect the bearing seals and housing surfaces against mechanical damage and contamination.
