Overview
Product Description
G38 is the wide-angle CV joint version of S38 — delivering 1,380 Nm at 540 rpm with an 80-degree CV joint at the tractor end. Like S38, G38 uses the 38×105.6 mm cross kit — a transitional specification between the 35 mm and 41 mm families that fits specific European OEM housings where neither standard 35 mm nor 41 mm is compatible. The CV joint adds constant-velocity output to the S38 torque class, extending G38 to high-angle applications where S38 vibration would be unacceptable.
G38 is a lower-volume model with a specific OEM application profile. If the implement manual or European OEM parts book specifies G38 or a CV joint shaft at the 38 mm pin diameter class, G38 is the correct specification. Confirm stock availability before committing to a delivery timeline.
G38 and S38 share the same cross-kit dimensions — a single 38×105.6 mm cross-kit part number covers both series. For OEM supply agreements on G38, contact Ever-Power Drive Line.
G Series vs Standard Cardan Shaft — G38 Comparison
| Feature | G Series (This Shaft) | T / L / S Series |
|---|---|---|
| Joint Type | CV Wide Angle Joint | Standard Cardan Joint |
| Max Operating Angle | 80° (CV end) | 25° continuous |
| Velocity Output | Constant velocity | Cyclic variation above 6° |
| Vibration at High Angles | Zero — eliminated | Increases with angle |
| Torque Class | 1,380 Nm @540 rpm | Equivalent S38 |
| Cross Kit | 38×105.6 mm | Same as equivalent T/S Series |
| Cross Kit Cross-Reference | Shared with S38 | As labelled |
Assembly Diagram — Component Reference
Component 1 is the CV wide angle joint — the key G Series differentiator from T/L/S Series
☈ Component 1: CV Wide Angle Joint
The CV (constant velocity) joint replaces the standard cross joint at the tractor end. It uses a ball-and-socket mechanism to deliver perfectly smooth, constant-velocity output at angles up to 80 degrees — eliminating the speed fluctuation that standard cardan joints produce above 6 degrees.

Key Features
80° Wide Angle CV Joint
The G Series CV joint allows operation at angles up to 80 degrees at the tractor end — more than three times the 25-degree limit of standard T, L, and S Series cardan joints. This enables G Series shafts in front-mounted implement drives, close-coupled mounts, and any application where the shaft angle regularly exceeds the standard cardan limit.
Constant Velocity Output
Standard cardan joints produce a sinusoidal speed variation at the output — the output shaft rotates faster then slower with each revolution, proportional to the operating angle. The G Series CV joint eliminates this variation, delivering perfectly constant-velocity output at any angle up to 80 degrees. This prevents vibration and eliminates implement gearbox acceleration fatigue.
Sealed Cross-Kit Bearings — IP67
Double-lip sealed needle-roller cross-kit bearing cups at the implement end, factory-filled with EP2 lithium complex grease. Grease nipple accessible with shield in place. Rated for 350+ hours between maintenance interventions under normal field conditions.
CE Safety Shield — Standard
CE-marked UV-stabilised HDPE bellows guard. CV joint end fitted with a flexible boot that accommodates the full 80-degree joint movement while protecting the CV joint grease cavity from contamination. OECD Code 4 compliant. Included as standard with every G Series unit.
Forged 20CrMnTi Steel Yokes
Drop-forged chromium-manganese-titanium alloy steel yokes, normalised and induction-hardened at bearing seat journals. The high-angle CV joint body is machined from the same alloy to the same surface hardness specification.
CE + ISO Certification Package
CE Declaration of Conformity, ISO 9001:2015, TS/16949 process certificate, LGPD compliance documentation. SGS third-party batch inspection available on contract orders.
Typical Applications
G Series CV joint — 60–90 hp tractor class at operating angles up to 80°
European-Spec Disc Mowers — Star Bore Housing
G38 is the wide-angle CV joint equivalent of S38 — same 38×105.6 mm cross kit, but with CV joint replacing the standard cardan at the tractor end. Required for European OEM disc mower housings specifying 38 mm bore star tube at this torque class with high-angle operation.
Compact Square Baler Drive — High Angle
Compact square baler drives where the baler hitch geometry creates high PTO shaft angles and the implement housing requires the 38 mm star bore specification.
Wide-Angle Transitional Applications
Applications requiring the torque level between G7 (30.2×106.5 mm) and G8 (35×106.5 mm) with the 38 mm pin diameter bore that fits specific European OEM housings.
Installation and Maintenance
Inspect the CV joint boot and anchor safety chains at both ends before first use
Confirm Torque Class
Calculate implement torque demand + 20% margin. Select the lowest G Series that meets the adjusted Nm figure.
Verify Operating Angle
Measure the maximum shaft angle at the tractor end at all implement positions. G Series handles up to 80° at the CV end; 25° at the implement cardan end.
Adjust Working Length
Verify 50 mm tube overlap at max implement height; 80 mm engagement at minimum. Tubes must not bottom out.
Inspect CV Joint Boot
Before first use, confirm the CV boot is correctly seated and both clamps are tight. A loose boot causes immediate CV joint contamination.
Anchor Safety Chains and Engage
Connect safety chains to non-rotating points. Engage PTO at low throttle first to verify smooth CV joint operation before running at full speed.
Frequently Asked Questions
- —G38 has a CV joint at the tractor end — 80 degree max angle, constant velocity
- —S38 has a standard cardan joint — 25 degree max angle
- —Both use the same 38×105.6 mm cross kit and identical torque ratings
- —Use G38 for high-angle applications; use S38 for standard angle applications at this torque class
- —G38 is required when the implement housing specifically requires the 38 mm bore (G38/S38 class)
- —If the implement fits G8 standard housing dimensions, use G8 — it has a wider availability
- —Always confirm the implement housing bore specification before ordering G38 vs G8
- —G38 is available — confirm stock availability before committing to delivery
- —Lead time: 10–15 days typical from stock
- —OEM blanket order arrangements available for regular G38 supply
- —No — G38 uses a 38 mm pin; G8 uses a 35 mm pin — different pressing tools required
- —G38 shares tooling with S38 if that is already in stock
- —G42 uses a 42 mm pin — also different from G38
- —CE Declaration of Conformity — standard with every unit
- —ISO 9001:2015 and TS/16949 — included with every batch
