Heavy-Duty PTO Shaft Compatible with CASE IH RB Series Round Balers \u2014 CAT4 & CAT5, Friction Clutch Included<\/h2>\n

Product Title: PTO Shaft for CASE IH Round Balers | CAT4\/CAT5 Constant Velocity Driveline with Friction Clutch<\/p>\n

\"PTO<\/p>\n

Product Overview & Compatibility<\/h2>\n

This agricultural transmission shaft is engineered as a direct-fit replacement for CASE IH round baler models requiring CAT4 or CAT5 constant velocity (CV) drivelines. It ships with a friction clutch pre-integrated, protecting your drivetrain from shock-load damage during bale formation cycles. Spline options cover the three most common CASE IH tractor outputs \u2014 1.375\u20116, 1.375\u201121, and 1.750\u201120 \u2014 so one SKU range serves the majority of RB series tractors without adapter kits.<\/p>\n

Compatible baler models: RB444, RB454, RB454 Silage, RB454 Rotor Cutter, RB455A, RB464, RB554, RB564<\/strong>. The standard input shaft is 1.375\u20116 spline; 1.375\u201121 and 1.750\u201120 configurations are available on request.<\/p>\n

PTO Shaft for CASE IH Round Balers \u2014 Technical Specifications<\/h2>\n

The CV driveline is built around a cold-drawn seamless steel tube with a wall thickness of \u22654 mm (CAT4) or \u22655 mm (CAT5), giving it the torsional rigidity needed at full rated power without adding unnecessary rotating mass. Yokes are precision-forged from heat-treated alloy steel (C45 or equivalent) and shot-peened to relieve surface stress. The friction clutch is factory-set to the torque value recommended for each baler model, with an external adjustment ring that lets service technicians re-calibrate in the field without full disassembly.<\/p>\n
