Sealed Both Sides

Lip seals on both sides of outer ring exclude contamination and retain a secondary grease charge that lubricates the seal contact faces.

PTFE Fabric Liner

Woven PTFE composite bonded to outer race spherical bore. Lower friction and higher load capacity than PTFE composite (GE..C) under oscillating conditions.

Chromium-Plated Inner Ring

Inner ring spherical surface chromium-plated HRC 58+ for hardness and corrosion resistance — the running surface against the PTFE fabric liner.

Single Axial Split

Outer ring split in axial direction for assembly. Phosphate-treated for corrosion resistance.

Higher Load than GE..C

PTFE fabric liner provides higher dynamic load capacity than GE..C PTFE composite for the same bore size due to the woven structure's higher compressive strength.

16 Bore Sizes

15 mm to 120 mm covering medium to large pivot joint applications requiring sealed, maintenance-free spherical accommodation.

PTFE Fabric Liner

Woven PTFE composite bonded to outer ring spherical bore. Higher load capacity than unwoven PTFE composite. Dry-running.

Chromium-Plated Inner Ring

HRC 58+, Ra 0.1–0.2 µm. Corrosion-resistant. Compatible with PTFE fabric without metallic wear.

NBR Lip Seals

Contact seals both sides. Retain seal-cavity grease. Exclude contamination. FKM option for high-temperature duty.

Hydraulic Cylinder Joints

Sealed maintenance-free clevis joints on hydraulic cylinders in construction, agricultural, and industrial machinery where re-lubrication between service intervals is not practical.

Agricultural Machinery

Sealed pivot joints in combine harvesters, balers, and precision seeders where contamination from soil and crop residue is severe and lubrication access is limited.

Off-Highway Equipment

Articulation joints on telescopic handlers, aerial work platforms, and off-road vehicles where sealed, maintenance-free spherical bearings reduce downtime between services.

Conveyor Systems

Sealed pivot joints on heavy conveyor drives, transfer chutes, and belt tensioning mechanisms in bulk material handling where contamination is continuous.

Outdoor Structures

Solar tracker horizontal pivot joints, antenna mount bearings, and outdoor equipment linkages where maintenance-free sealed operation is required in all weather conditions.

Wind Turbine Pitch Systems

Blade pitch pivot bearings in wind turbines use GE..ET 2RS for the combination of maintenance-free operation, contamination sealing, and high load capacity over long service intervals.

🔎 Housing Bore

H7 tolerance. Press outer ring into housing using press tool on outer ring end face. The axial split must be located at the point of minimum load in the housing.

🔧 Shaft Tolerance

h6 for press fit; js6 for tight sliding. Inner ring chromium-plated surface is the running surface — do not grind or machine after installation.

📈 Do Not Re-lubricate

The PTFE fabric liner provides dry lubrication. Do not attempt to inject grease into the spherical contact — this pressurises the lip seals and can extrude them from their grooves.

⚙ Seal Inspection

Inspect lip seals at each equipment service for extrusion, cracking, or contamination bypass. Replace bearings with compromised seals immediately — contamination ingress accelerates liner wear rapidly.

🌡 Temperature Limit

NBR seals: −30°C to +110°C. FKM seals: −20°C to +200°C. PTFE fabric liner is unaffected across both ranges.

✅ End-of-Life

Replace when detectable play develops or when friction increases noticeably. PTFE fabric liner cannot be replenished. Inspect at every equipment overhaul.

①

Identify Load Type

Confirm maintenance-free sealed operation is required. If re-lubrication is feasible, GE..ES 2RS may be more cost-effective.

②

Select Bore & Series

Match bore d to shaft nominal. Verify outer diameter D and width B. Note GE..ET 2RS has larger B than GE..C due to seal housings.

③

Verify Misalignment Angle

Verify dynamic load rating C ≥ equivalent load. Check α ≤ rated misalignment. Confirm oscillating motion only — no continuous rotation.
