Overview
Product Description
G8 enters the 35 mm cross-kit pin diameter family — a step up from the 30.2 mm family of G5, G6, and G7. The 35×106.5 mm cross kit delivers 1,240 Nm at 540 rpm in constant-velocity configuration. This is the CV joint equivalent of S8 — same cross-kit dimensions, same torque class, but with the G8 CV joint replacing the standard S8 cardan joint at the tractor end.
The jump from the 30.2 mm family (G5/G6/G7) to the 35 mm family (G8) requires a new set of workshop pressing tools — the 30.2 mm tooling does not fit the 35 mm pin. For workshops adding G8 to an existing G5/G6/G7 stock, this tooling investment is required. G8 and S8 cross kits are identical, so workshops already stocking S8 have the correct tools and cross kits for G8 service.
G8 is a lower-volume series than G5/G6 due to the more specific application profile. Stock availability should be confirmed before committing to a delivery deadline. For regular OEM supply of G8, a blanket order arrangement ensures priority allocation. Contact Ever-Power Drive Line for availability and OEM terms.
G Series vs Standard Cardan Shaft — G8 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 | 1,240 Nm @540 rpm | Equivalent T8 / S8 |
| Cross Kit | 35×106.5 mm | Same as equivalent T/S Series |
| Cross Kit Cross-Reference | Shared with T8 / S8 | 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°
Large Disc Mowers and Mower-Conditioners — 70–90 hp
G8 is the standard CV joint specification for large disc mowers and mower-conditioners in the 70–90 hp class. The 35 mm pin diameter provides the bearing capacity needed for sustained high-torque, high-angle mowing operation.
Front-Mounted Square Baler Feeder
Front-mounted baler feeder drive applications requiring CV joint operation at angles that standard cardan joint T8 or S8 cannot sustain — combines high torque (1,240 Nm continuous) with constant-velocity output.
Industrial Wide-Angle Drive — Heavy Duty
Heavy-duty industrial rotary equipment where both high torque and large operating angle are required simultaneously. G8 covers applications where T8 standard cardan shaft vibration at high angles causes implement gearbox or bearing failures.
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.
