GE 20 ES 2RS FLURO Dimensions

Catalogue dimensions:

d - Bore Diameter: 20 mm
D - Outside Diameter: 35 mm
B - Inner Ring Width: 16 mm
C - Outer Ring Width: 12 mm
dk - Spherical Diameter: 29 mm
Basic Dimensions: 20x35x16 mm
Weight: approx. 0.065 kg

The distinction between B = 16 mm and C = 12 mm is important when comparing spherical plain bearings with apparently identical basic dimensions.

Steel/Steel Sliding Contact Combination

GE 20 ES 2RS FLURO uses the sliding contact combination:

Steel / Steel

The bearing rings are manufactured from bearing steel 100Cr6 / 1.3505 / AISI 52100. The sliding surfaces are treated with molybdenum disulfide - MoS2.

This is a maintenance-required, relubricatable design, rather than a maintenance-free spherical plain bearing with a PTFE-based sliding layer.

MoS2 Sliding Surface

The steel/steel sliding surfaces are treated with:

MoS2 - Molybdenum Disulfide

MoS2 is used on the sliding surfaces as part of the bearing's tribological system.

For this bearing design, the MoS2-treated steel/steel contact works together with periodic lubrication. The bearing should therefore not be confused with maintenance-free spherical plain bearing variants.

2RS Seals

The 2RS designation identifies a bearing with seals on both sides.

Catalogue data for this FLURO version specify:

Sealing: both sides
Seal Type: contact seal
Seal Material: NBR - Nitrile Butadiene Rubber
Seal Material Temperature Range: -30°C to +120°C

The seals help protect the sliding contact surfaces against external contamination and help retain lubricant within the bearing.

Relubrication

GE 20 ES 2RS FLURO is designed for periodic relubrication.

The bearing incorporates a lubrication arrangement with a lubrication groove and hole, allowing lubricant to reach the sliding surfaces during maintenance.

This is an important selection parameter because spherical plain bearings with the same basic dimensions may use different sliding contact materials and may be designed as either maintenance-required or maintenance-free bearings.

Dynamic Load Rating

Catalogue data for this specific FLURO bearing specify:

Dynamic Load Rating C: 30,000 N / 30 kN

The dynamic load rating is a catalogue engineering parameter used when evaluating the bearing under dynamic operating conditions.

It should be considered together with the actual load direction, oscillation angle, lubrication, operating temperature and required service life.

Static Load Rating

The catalogue static load rating is:

Static Load Rating C0: 146,000 N / 146 kN

The static rating is significantly higher than the dynamic rating, which is characteristic of spherical plain bearing load-rating methodology.

The catalogue value should not be interpreted simply as the maximum permissible working load under every operating condition.

Maximum Angle of Tilt

The specified maximum angle of tilt for GE 20 ES 2RS FLURO is:

9°

The spherical geometry allows the inner ring to articulate relative to the outer ring, enabling the bearing to accommodate angular movement within its specified range.

DIN ISO 12240-1

GE 20 ES 2RS FLURO corresponds to:

DIN ISO 12240-1

This standard covers radial spherical plain bearings.

The dimensional series for this bearing is:

Series E

The standard designation and dimensional series are useful when comparing technically corresponding spherical plain bearings.

GE 20 E-2RS and GE 20 ES-2RS

This FLURO bearing can be encountered under the designations:

GE 20 E-2RS
GE 20 ES-2RS

Both designations are associated with the same FLURO product specification:

20x35x16 mm -> Steel/Steel -> Sealed on both sides -> Relubricatable

Keeping both forms in the product description improves catalogue identification when customers search using different manufacturer or industry designation formats.

Selection and Interchangeability

When selecting an equivalent for GE 20 ES 2RS FLURO, the basic dimensions alone are not sufficient.

The relevant catalogue parameters are:

Designation: GE 20 ES 2RS
Dimensions: 20x35x16 mm
Outer Ring Width C: 12 mm
Sliding Combination: Steel/Steel
Sealing: 2RS
Lubrication: Relubricatable
Dynamic Load Rating: 30 kN
Static Load Rating: 146 kN
Maximum Angle of Tilt: 9°
Standard: DIN ISO 12240-1

Particular attention should be paid to the steel/steel, relubricatable construction, because maintenance-free spherical plain bearings with identical dimensions may use a fundamentally different sliding contact system.
