FKL LSGR 207 TBS 35x125x40 mm

FKL LSGR 207 TBS 35x125x40 mm - Agricultural Flanged Bearing Unit

FKL LSGR 207 TBS 35x125x40 mm is a flanged bearing unit manufactured by FKL, a Serbian bearing manufacturer specializing in agricultural machinery components. The unit features a self-aligning ball bearing mounted in a four-bolt flange housing, with a 35 mm bore diameter, 125 mm overall outside diameter, and 40 mm overall width. The TBS sealing arrangement provides additional protection against soil, dust, moisture, and other contaminants encountered in agricultural applications.

Technical Specifications - FKL LSGR 207 TBS

The FKL LSGR 207 TBS is supplied as a bearing unit with an integrated housing and specialized sealing arrangement.

Its construction is intended for agricultural equipment operating in environments exposed to dust, soil particles, moisture, and mechanical contamination.

What Does LSGR 207 TBS FKL Mean?

The designation identifies the bearing unit family, dimensional size, sealing configuration, and manufacturer.

• LSGR 207 - FKL agricultural flanged bearing unit design, incorporating a bearing with a nominal 35 mm bore.

• 207 - Bearing size designation corresponding to a 35 mm shaft diameter.

• TBS - Specific FKL sealing execution combining protective sealing elements for agricultural operating conditions.

• FKL - Manufacturer of the bearing unit, based in Serbia.

The complete designation LSGR 207 TBS should be retained when identifying or ordering a replacement.

A bearing unit with the same shaft diameter but a different housing or sealing configuration is not necessarily interchangeable.

TBS Sealing System

The TBS execution incorporates a sealing arrangement designed to reduce contamination entering the bearing.

Its construction includes:

• S seal - Protective sealing element on the housing base side.

• T seal - Triple-lip sealing arrangement on the side exposed to external contamination.

• Metal flinger - Additional mechanical protection that helps deflect dirt and other contaminants away from the sealing area.

The combination of sealing lips and a metal flinger provides additional protection in environments where bearings are exposed to soil, dust, crop residue, and moisture.

This arrangement is particularly relevant to agricultural rollers and soil cultivation equipment.

Construction and Operating Principle

The FKL LSGR 207 TBS is a complete bearing unit consisting of a bearing insert, flanged housing, sealing components, and mounting arrangement.

Bearing Insert

The internal ball bearing supports the rotating shaft and accommodates loads according to the bearing design and the limits of the complete unit.

Its self-aligning arrangement can accommodate limited installation misalignment within the manufacturer's permitted operating conditions.

Four-Bolt Flanged Housing

The housing provides a mounting interface between the bearing and the machine structure.

The unit features four M12 mounting holes positioned on a 100 mm pitch circle diameter.

This arrangement allows the bearing unit to be secured to the machine frame or a suitable mounting structure.

The housing must be supported correctly to prevent distortion and uneven loading.

Protective Sealing Arrangement

The TBS sealing system helps protect the rolling elements and raceways against external contamination.

The triple-lip seal and metal flinger are particularly important in agricultural environments where abrasive particles can accelerate bearing wear.

The effectiveness of the sealing system depends on correct installation, operating conditions, and maintenance practices.

Typical Applications of FKL LSGR 207 TBS

The LSGR 207 TBS bearing unit is associated with agricultural machinery requiring shaft support in demanding operating environments.

Typical applications include:

• Agricultural packer rollers.

• Soil consolidation rollers.

• Seedbed preparation equipment.

• Tillage machinery.

• Agricultural roller shaft assemblies.

These applications are consistent with the construction and intended function of the bearing unit.

LEMKEN Machinery References

FKL catalog references associate the LSGR 207 TBS with selected LEMKEN agricultural machinery, including:

• LEMKEN RUBIN 10/700

• LEMKEN HELIODOR

• LEMKEN ZIRKON

The associated LEMKEN reference number is 3199372.

Compatibility must be confirmed against the machine's original parts documentation, model configuration, and production version.

A general model family reference does not guarantee compatibility with every machine in that range.

Alternative Designations and Cross-Reference Numbers

The product may be identified using the following designation formats:

• FKL LSGR 207 TBS

• LSGR 207 TBS FKL

• LSGR207TBS

• LSGR 207 TBS 35x125x40

Catalog Cross-References

These numbers are catalog references associated with the bearing unit.

They should not be interpreted as unconditional guarantees of interchangeability.

Before replacing the original unit, verify housing geometry, shaft diameter, mounting hole arrangement, sealing execution, and overall dimensions.

FKL LSGR 207 TBS vs Standard UC207 Bearing

The FKL LSGR 207 TBS is not equivalent to a standard UC207 bearing insert.

Although both products may have a nominal 35 mm bore, their constructions and mounting requirements differ significantly.

A UC207 bearing insert cannot directly replace the complete LSGR 207 TBS unit without evaluating the housing, mounting arrangement, and sealing requirements.

Bearing Selection and Interchangeability

Before ordering the FKL LSGR 207 TBS, verify the following:

• Complete manufacturer designation LSGR 207 TBS.

• Shaft diameter of 35 mm.

• Overall dimensions of 35x125x40 mm.

• Four-bolt mounting configuration.

• Mounting pitch circle diameter of 100 mm.

• M12 mounting hole specification.

• Housing geometry and flange thickness.

• TBS sealing arrangement.

• Required dynamic and static load ratings.

• Operating speed.

• Shaft alignment and mounting surface condition.

• Exposure to dust, soil, water, and other contaminants.

• Original equipment reference number, where applicable.

For agricultural equipment, the sealing configuration and housing geometry can be as important as the nominal shaft diameter.

Matching dimensions alone do not guarantee complete mechanical interchangeability.

Installation and Maintenance

Preparation Before Installation

Before mounting the bearing unit, inspect the shaft, mounting surface, and fasteners.

Remove dirt, corrosion, and foreign particles from the installation area.

Check that the shaft is free from excessive wear and that the housing mounting surface provides uniform support.

Correct Mounting

Position the bearing unit correctly on the shaft and against the mounting surface.

Tighten the four mounting fasteners evenly using the torque specifications applicable to the machine and fastener arrangement.

Avoid mounting conditions that distort the housing or introduce excessive stress into the bearing.

The shaft and bearing unit must be aligned according to the equipment manufacturer's requirements.

Seal Protection

Inspect the sealing components for damage before installation.

Avoid direct mechanical contact with the sealing lips and metal flinger during assembly.

Do not direct high-pressure water jets at the seals, as this can force contaminants or moisture into the bearing.

Lubrication and Inspection

Follow the lubrication and maintenance instructions applicable to the exact FKL bearing unit and machine.

During operation, inspect for:

• Unusual noise or vibration.

• Excessive operating temperature.

• Increased bearing play.

• Seal damage.

• Contamination around the bearing housing.

• Loose mounting fasteners.

Early identification of these conditions can help prevent unexpected bearing failure.
