UCP210-J7 FAG 50 mm Plummer Block Bearing Unit

UCP210-J7 FAG 50 mm Plummer Block Bearing Unit

UCP210-J7 FAG is a complete Schaeffler/FAG plummer block bearing unit with a 50 mm bore, designed for direct mounting on a metric shaft. The unit combines a cast-iron pillow block housing with a self-aligning insert ball bearing. The inner ring is secured to the shaft by grub screws, while RSR seals protect the bearing. The J7 housing fit provides normal swivel torque of the bearing insert in the housing.

Technical Data - FAG UCP210-J7

What Is FAG UCP210-J7?

FAG UCP210-J7 is a complete housed bearing unit, not just a bearing housing.

The unit combines:

• a plummer block housing

• a self-aligning insert ball bearing

• shaft locking by grub screws

• integrated bearing seals

The nominal shaft diameter is:

50 mm

This ready-to-mount design simplifies the construction and maintenance of many industrial shaft-support arrangements.

UCP Plummer Block Design

The FAG UCP series consists of insert bearing units in a robust foot-mounted housing.

The insert bearing has a spherical outside surface that works with the corresponding spherical seating surface inside the housing.

This design allows the bearing insert to swivel within the housing and compensate for suitable levels of static misalignment between the shaft and housing.

This self-aligning capability should not, however, be considered a substitute for correct machine alignment.

50 mm Bore Diameter

FAG UCP210-J7 has a nominal bore diameter of:

d = 50 mm

The unit is therefore intended for mounting directly onto a 50 mm metric shaft when the shaft and application meet the relevant mounting requirements.

The metric UCP210 version should not be confused with inch-bore variants from similar product families.

What Does J7 Mean?

For this bearing unit, Schaeffler specifies:

Housing fit: J7

with:

Normal swivel torque

J7 relates to the fit between the spherical outside surface of the bearing insert and the corresponding housing seat.

It should not be confused with bearing internal clearance designations such as C3.

Shaft Locking by Grub Screws

The bearing insert is secured to the shaft by:

grub screws in the extended inner ring

This locking principle provides a straightforward method of fixing the bearing unit to the shaft without requiring an adapter sleeve.

Correct tightening and shaft preparation are important for reliable operation.

RSR Sealing

The bearing unit is equipped with:

RSR seals

The sealing system helps retain lubricant inside the bearing and protects the rolling contact area against contamination from the surrounding environment.

Actual sealing performance depends on operating conditions such as:

• contamination

• moisture

• shaft speed

• temperature

• maintenance conditions

Grey Cast Iron Housing

The UCP210 housing is manufactured from:

grey cast iron

The housing has a long foot-mounted base designed for stable attachment to the supporting machine structure.

Cast-iron housings are widely used in industrial bearing units because they provide a robust and rigid support for the bearing insert.

FAG UCP210-J7 Dimensions

Important mounting dimensions include:

Bore diameter d: 50 mm

Overall length L: 206 mm

Overall height H2: 114 mm

Mounting hole distance J: 159 mm

Mounting slot width N: 20 mm

Mounting slot length N1: 25 mm

These dimensions are particularly important when replacing an existing housed bearing unit.

Basic Dynamic Load Rating Cr

The basic dynamic radial load rating is:

Cr: 37.5 kN

This value is used in bearing life calculations.

It should not be interpreted as the maximum permissible load for the complete bearing unit under all operating conditions.

Actual load capacity of an installation depends on the complete arrangement, including the housing, mounting surface, shaft, fasteners, operating speed and direction of loading.

Basic Static Load Rating C0r

The basic static radial load rating is:

C0r: 23.2 kN

This parameter is used when evaluating bearing performance under static loading or very slow movement.

Fatigue Load Limit Cur

The fatigue load limit is:

Cur: 1.21 kN

This parameter is used in advanced bearing life calculations and should not be interpreted as the maximum permissible operating load.

Mass

The complete FAG UCP210-J7 bearing unit has a mass of approximately:

2.802 kg

This value refers to the complete housed bearing unit rather than only the insert bearing.

Self-Aligning Function

The insert bearing has a spherical outside surface that allows it to swivel inside the corresponding spherical housing seat.

This helps compensate for suitable levels of static misalignment resulting from:

• mounting inaccuracies

• alignment differences between bearing positions

• shaft deflection

• supporting structure tolerances

The permissible misalignment depends on the actual bearing arrangement and operating conditions.

UCP210 vs UC210

These designations should not be treated as identical products.

UC210

Refers to the insert bearing.

UCP210

Refers to the complete foot-mounted bearing unit incorporating the appropriate insert bearing and housing.

If a complete ready-to-mount pillow block unit is required, UCP210 is the relevant product type.

UCP210 vs UCF210

Both units can be designed around an insert bearing with a nominal 50 mm bore, but their housings are fundamentally different.

UCP210

Foot-mounted pillow block / plummer block housing.

UCF210

Square flange housing unit.

They are therefore not directly interchangeable in terms of machine mounting.

UCP210 vs UCFL210

UCP210

Foot-mounted bearing unit.

UCFL210

Two-bolt flange bearing unit.

The correct version depends primarily on the required mounting arrangement and machine structure.

Typical Applications

FAG UCP bearing units can be used in appropriately designed applications such as:

• conveyor systems

• agricultural machinery

• material-handling equipment

• industrial machinery

• production equipment

• drive systems

• processing machinery

• general shaft-support arrangements

The suitability of UCP210-J7 for a specific application must be determined from the actual loads, shaft speed, operating environment and mounting conditions.

Selection Checklist

Before ordering FAG UCP210-J7, verify:

1. Complete designation UCP210-J7.

2. Shaft diameter of 50 mm.

3. Foot-mounted housing design.

4. Mounting hole distance of 159 mm.

5. Available installation dimensions.

6. Grub-screw shaft locking.

7. Required radial load capacity.

8. Operating speed.

9. Environmental conditions.

10. Lubrication and sealing requirements.

The same 50 mm bore diameter does not automatically make different housed bearing units interchangeable.

Installation Considerations

Before installation, check:

• shaft diameter and condition

• mounting surface

• alignment of bearing positions

• housing support surface

• condition of the locking screws

• required lubrication

• freedom of the bearing insert to align correctly

The housing should be mounted on a sufficiently rigid and flat supporting surface.

The shaft locking screws should be tightened according to the appropriate Schaeffler installation requirements.
