Overview
Product Description
S10 is the top of the S Series — a 41×118 mm cross-kit shaft delivering 1,905 Nm at 540 rpm and 3,500 Nm peak. The 41 mm cross-kit pin diameter is unique to S10 in the S Series; no other S Series model uses this bearing family. Workshop tooling (pressing fixtures, snap-ring pliers, and bearing cups) is specific to S10 and separate from the 30.2 mm and 35 mm tool sets used for lower series. S10 is also available in the equivalent T Series as T10 — the tube profile (star vs triangular) is the only selection criterion between them for a given implement housing specification.
At this torque class, the selection between S10 (star) and T10 (triangular) is entirely determined by the implement input housing design. Both transmit identical power and share the same cross-kit dimensions. If the implement housing is machined for a star bore, S10 is correct; if triangular, T10 is correct. Never substitute tube profiles at this torque class — the mechanical consequences of incorrect tube engagement in a high-torque housing are severe.
S10 is available from stock in standard lengths. For the largest OEM applications — custom compressed length, integrated CV joint, specific yoke configuration — lead time is 25–30 days from DWG approval with MOQ 50 pieces. Contact Ever-Power Drive Line for engineering review and pricing on S10 OEM contracts.

Key Features
Star Tube Profile — Six-Lobe Bore
The star (six-lobe) tube cross-section provides the highest torsional rigidity per unit outer diameter of any standard agricultural PTO tube profile. Specified by European implement OEMs for input housings machined to star bore dimensions — incompatible with triangular or lemon tube profiles.
Sealed Cross-Kit Bearings — IP67
Double-lip sealed needle-roller bearing cups, factory-filled with EP2 lithium complex grease. Grease nipple accessible with shield in place. Rated for 350+ hours between maintenance interventions in standard field conditions.
CE Safety Shield — Standard
CE-marked UV-stabilised HDPE bellows guard matched to S Series tube outer diameter. Spring-clip anchors and chain points at both ends. OECD Code 4 compliant. Included as standard with every S Series unit.
Forged 20CrMnTi Steel Yokes
Drop-forged chromium-manganese-titanium alloy steel yokes, normalised and induction-hardened at bearing seat journals. Designed for sustained peak torque applications in large baler and forage harvester duty cycles.
All Spline Standards Available
1-3/8 inch Z6 (540 rpm), 1-3/4 inch Z20 (1,000 rpm), and 1-3/8 inch Z21 push-pin or bolt-clamp yokes. Both ends specified independently at order.
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
S Series star tube — 120–200 hp tractor class applications
Maximum Output Forage Harvesters
Self-loading forage wagons and pull-type precision harvesters on the largest available tractors. S10 delivers 1,905 Nm at 540 rpm — the maximum capacity in the standard S Series — for sustained flywheel and rotor drive in high-density crop conditions.
Large Square Balers — 120–160 hp
High-density large square baler plunger drive on 120–160 hp tractors. The 41 mm cross-kit pin diameter and 118 mm journal provide the bearing capacity required for the 3,500 Nm peak loads of high-output square baling.
Industrial PTO Applications — Heavy Duty
Heavy-duty industrial rotary cutters, large wood chippers, and agricultural processing equipment requiring the maximum available star tube torque class at either 540 or 1,000 rpm PTO.
Installation and Maintenance
Attach safety chain to a fixed non-rotating point on both tractor and implement
Confirm Torque Class
Calculate implement demand (Nm). Add 20% safety margin. Select the lowest S Series where Nm@540 (or Nm@1000) exceeds the adjusted figure.
Adjust Working Length
Measure coupling centre distance with implement attached. Verify 50 mm min tube overlap at full extension, 80 mm at full compression.
Engage Yoke Connections
Push-pin yoke: engage at PTO stub and confirm audible click and positive retention. Clamp yoke: torque to manufacturer specification.
Anchor Safety Chains
Connect tractor-side chain to guard or frame; implement-side chain to implement body. Verify taut at working height.
Grease Before First Use
Apply EP2 lithium complex NLGI 2 grease (2–3 pumps) to both cross-kit nipples. Service every 8 hours; 4 hours in wet or abrasive conditions.
Frequently Asked Questions
- —S10 and T10 share the same 41×118 mm cross kit and identical torque ratings (1,905 Nm at 540 rpm)
- —Tube profile differs: S10 uses star bore, T10 uses triangular (trilobe) bore
- —Selection is determined entirely by implement input housing specification — never substitute
- —Cross kits are interchangeable; tube and yoke assemblies are not
- —Yes — Z20 (1-3/4 inch 20-spline) yokes are available for both ends
- —At 1,000 rpm, S10 is rated at 1,610 Nm — verify implement demand against this figure
- —Specify Z20 at order; standard stock is Z6 (540 rpm)
- —41 mm pressing tool and snap-ring pliers for the S10 yoke bore
- —This tooling is specific to S10 — not compatible with 30.2 mm or 35 mm tools
- —Bearing cup installation requires a press or vise with 41 mm adapter — do not hammer-install
- —MOQ 1 piece from stock in standard lengths
- —OEM custom configurations: MOQ 50 pieces, lead time 25–30 days from DWG approval
- —For contract volumes above 200 pieces per year, contact Ever-Power Drive Line for blanket order pricing
- —A shear bolt torque limiter is strongly recommended for all S10 applications
- —Set the release torque below 3,500 Nm (S10 peak) to protect the shaft and implement gearbox
- —At this torque class, implement gearbox repair costs significantly exceed shaft replacement costs — a limiter is essential investment protection
