GE 40 ES 2RS CT 40x62x28 Spherical Plain Bearing

DESCRIPTION

GE 40 ES 2RS CT is a radial spherical plain bearing measuring 40x62x28 mm. Catalogue dimensions for the GE40ES-2RS design are: d 40 mm, D 62 mm, B 28 mm, C 22 mm and spherical diameter dk 53 mm. The ES-2RS construction uses a steel/steel sliding contact combination, incorporates lubrication grooves and holes for relubrication and is sealed on both sides. This is a maintenance-required spherical plain bearing designed for periodic grease lubrication.

GE 40 ES 2RS CT 40x62x28 Spherical Plain Bearing

GE 40 ES 2RS CT is a radial spherical plain bearing with dimensions 40x62x28 mm.

Complete identification:

CT -> GE 40 ES 2RS -> 40x62x28 mm -> Steel/Steel -> 2RS -> Relubricatable

The GE ES-2RS design combines a steel/steel sliding contact system with sealing on both sides and a lubrication arrangement for periodic relubrication.

GE 40 ES 2RS CT Dimensions

Catalogue dimensions for GE40ES-2RS:

d - Bore Diameter: 40 mm
D - Outside Diameter: 62 mm
B - Inner Ring Width: 28 mm
C - Outer Ring Width: 22 mm
dk - Spherical Diameter: 53 mm
r1 min.: 0.6 mm
r2 min.: 1 mm
Basic Dimensions: 40x62x28 mm

The distinction between B = 28 mm and C = 22 mm is important when checking installation dimensions and comparing spherical plain bearings.

Steel/Steel Sliding Contact

The GE ES-2RS bearing design uses the sliding contact combination:

Steel / Steel

In this construction, the spherical sliding surfaces of the inner and outer rings operate directly against each other. Catalogue documentation for steel/steel GE40ES-2RS bearings specifies molybdenum disulphide treatment of the sliding surfaces to reduce sliding friction.

This design should be distinguished from maintenance-free spherical plain bearings using PTFE-based sliding materials.

Relubricatable Design

GE40ES-2RS is a maintenance-required bearing designed for periodic relubrication with grease. SKF catalogue data specify regular grease relubrication for this bearing type.

The construction incorporates:

lubrication grooves
lubrication holes

These provide a path for lubricant to reach the steel/steel sliding contact surfaces.

Periodic lubrication is therefore an integral part of the operating concept of this bearing design.

2RS Sealing

The suffix 2RS identifies the sealed version.

GE40ES-2RS bearings have seals on both sides, protecting the sliding contact area against contamination and helping retain lubricant within the bearing.

SKF catalogue documentation describes the sealing solution for GE40ES-2RS as double-lip seals.

Spherical Diameter dk

An additional catalogue dimension relevant to the internal geometry is:

dk = 53 mm

This is the spherical diameter associated with the sliding contact geometry of the bearing.

It is useful when comparing technically corresponding spherical plain bearing designs rather than relying only on the three basic dimensions 40x62x28 mm.

Angular Movement

The spherical sliding geometry permits angular movement of the inner ring relative to the outer ring.

Catalogue values for GE40ES-2RS vary between manufacturers. For example, one catalogue gives approximately 7°, while SKF documentation for its own version specifies 6°.

For this reason, I would not assign a specific maximum tilt angle to the CT version without CT catalogue confirmation.

Load Ratings - CT Version

I would also avoid publishing a dynamic or static load rating for GE 40 ES 2RS CT without the CT manufacturer's catalogue.

This is important because nominally equivalent GE40ES-2RS bearings can have different published ratings depending on manufacturer and rating methodology. Available examples range from 99/495 kN to 114/686 kN for dynamic/static catalogue ratings.

These values therefore must not be presented as CT specifications without direct manufacturer confirmation.

Selection and Interchangeability

When selecting a replacement for GE 40 ES 2RS CT, verify the complete bearing specification:

Designation: GE 40 ES 2RS
d: 40 mm
D: 62 mm
B: 28 mm
C: 22 mm
dk: 53 mm
Sliding Contact: Steel/Steel
Sealing: 2RS
Maintenance: Relubricatable

A bearing with the same 40x62x28 mm dimensions should not automatically be considered technically identical if it uses a different sliding contact combination or maintenance concept.

FAQ

What are the dimensions of GE 40 ES 2RS CT?

The basic dimensions are 40x62x28 mm: d = 40 mm, D = 62 mm and B = 28 mm. The outer ring width C is 22 mm and spherical diameter dk is 53 mm.

What type of bearing is GE 40 ES 2RS?

It is a radial spherical plain bearing with a steel/steel sliding contact combination.

What does 2RS mean?

2RS identifies a bearing sealed on both sides.

Does GE 40 ES 2RS require lubrication?

Yes. The steel/steel GE40ES-2RS design requires regular relubrication with grease.

Does the bearing have lubrication grooves?

Yes. Catalogue documentation for the GE40ES-2RS steel/steel design specifies grooves and through holes for relubrication.

What is the dynamic load rating of GE 40 ES 2RS CT?

I would not assign a value without the CT manufacturer's catalogue, because published load ratings for GE40ES-2RS vary between manufacturers.

Is GE 40 ES 2RS maintenance-free?

No. The steel/steel version is a maintenance-required, relubricatable spherical plain bearing.

AI OVERVIEW

GE 40 ES 2RS CT is a radial spherical plain bearing measuring 40x62x28 mm. Standard GE40ES-2RS catalogue dimensions are d 40 mm, D 62 mm, B 28 mm, C 22 mm and dk 53 mm. The ES-2RS design uses a steel/steel sliding contact combination, is sealed on both sides and is designed for periodic grease relubrication through lubrication grooves and holes. Because dynamic/static load ratings and permissible tilt angles differ between manufacturers, these parameters should be taken directly from the CT catalogue rather than from another brand's GE40ES-2RS data.
