When a 36 mm Face Mount Must Meet a 100 mm Servo Flange

A common field challenge is mounting a face mount flange with a 36 mm centering hub onto a servo flange with a 100 mm envelope and a 60 mm centering bore. The SICK BEF-FA-036-100 aluminum adapter bridges that mismatch in a single passive part. Its inboard hub measures Ø 36 mm, while the outboard flange is Ø 100 ±0.1 mm with a Ø 60 f8 centering bore.

Because the adapter is a passive mechanical component, it introduces no electrical interface and no operating temperature, input voltage, or power supply requirement. Those parameters are not specified for this part. The design is built for demanding environments where alignment and repeatable mounting matter.

Key Features and Technical Specifications of the BEF-FA-036-100

• Material: Aluminum construction keeps the adapter light and corrosion-resistant.
• Inboard centering hub: Ø 36 mm, matching the face mount flange side.
• Outboard mounting flange: Ø 100 ±0.1 mm with a Ø 60 f8 centering bore.
• Center bore: Ø 36 mm through bore with a 90° chamfer at the face.
• Axial envelope: 3.1 mm flange plate plus 10 mm centering hub spigot, 13.1 mm maximum.
• Dimensions: Approximately 100 × 100 × 13.1 mm rectangular envelope.
• Series: SICK Flanges series, part number 2029161.

The Ø 60 f8 centering bore is the distinctive feature. Its f8 tolerance class supports a close fit on the servo flange side, which helps maintain concentricity during assembly.

Applications and Use Cases

This adapter suits motion systems that combine a 36 mm face mount interface with a 100 mm servo flange pattern. For example, a retrofit may call for a new servo flange while the existing face mount hardware remains in place. In that case, This unit provides the transition without machining either component.

Oil and gas automation cabinets often use compact servo axes where space is limited. The 13.1 mm maximum axial envelope allows the adapter to fit into tight assemblies. Furthermore, the aluminum body resists typical industrial contaminants. As a result, maintenance teams can plan vfd replacement and servo motor replacement work around a stable mechanical interface.

When sourcing vfd parts and motion accessories, engineers should confirm that the flange pattern and centering bores match the intended hardware. This unit is specific to the 36 mm to 100 mm configuration described here.

Installation and Setup Guidance

Installation begins with cleaning both mating faces and checking the centering bores for damage. The adapter should seat fully against the face mount flange before fasteners are tightened. Because the through bore is Ø 36 mm with a 90° chamfer, the shaft passage should be aligned before final torque is applied.

Fastener selection must match the mounting holes on the outboard flange. The adapter's hole pattern is defined on the technical drawing. Therefore, verify the thread and spacing against the mating servo flange before installation. Do not force the adapter onto a hub with a different diameter.

After assembly, rotate the shaft by hand to confirm free movement. Any binding may indicate misalignment or an incorrect centering fit. Finally, record the installation for future maintenance reference.

Maintenance and Reliability in Demanding Environments

As a passive aluminum component, This unit has no wear parts that require scheduled service. Periodic inspection should focus on the centering bores, the flange faces, and the fastener condition. In oil and gas environments, check for corrosion or debris that could affect the f8 fit.

Because the adapter is built for demanding environments, it supports reliability you can depend on in mission-critical motion assemblies. However, operating temperature and protection rating are not specified for this part. Therefore, confirm the surrounding assembly's environmental limits with the system designer.

If the adapter is removed, inspect the 90° chamfer and the Ø 36 mm through bore for nicks. A damaged centering bore can compromise concentricity. Replace the adapter if the fit no longer holds.

Compatibility and Integration Notes

This unit is compatible with a face mount flange that has a 36 mm centering hub. It presents a 100 mm servo flange interface with a 60 mm f8 centering bore. Confirm both interfaces before ordering, because this adapter does not convert other flange sizes.

No electrical connection, fieldbus protocol, or power supply is associated with this passive part. Therefore, no gateway or connection module is required for the adapter itself. For the surrounding drive and motor, follow the respective manufacturer's integration instructions.

Frequently Asked Questions

What does the SICK unit adapter do?

It adapts a face mount flange with a 36 mm centering hub to a 100 mm servo flange with a 60 mm f8 centering bore. The part is passive and requires no power supply.
