Case-IH® Compatible Straw Spreader Shaft Bearing (Hex Bore)
Ensure the processing and discharge reliability of your residue management system with this premium aftermarket straw spreader shaft bearing. Specifically engineered for Case-IH® combine harvesters, this high-performance bearing is the professional solution for repairing worn components within the primary straw spreader and chaff distribution layout.
Manufactured to strict agricultural machinery standards, this specialized single-row deep groove ball bearing features a precision-machined 7/8" hexagonal bore to provide absolute, positive engagement with the hex drive shaft. Designed to withstand heavy rotational strain and the intense, dust-heavy conditions of seasonal residue processing, it features an extended inner ring and high-integrity contamination-resistant seals to exclude dirt, chaff, and fine grit. This high-strength replacement part ensures your spreader drive remains in top condition, securing a reliable and significantly longer service life.

Expert Maintenance Review
The straw spreader shaft bearing operates in one of the highest-fouling, most abrasive micro-environments on the entire combine harvester. Positioned directly under or behind the sieve discharge, it is continuously subjected to a high-velocity stream of chopped crop material, fine dust, and aggressive sap residues that strip standard lubrication away. Once dust breaches the seals, internal abrasion rapidly destroys the ball track, leading to excessive heat, shaft lock-up, or thrown spreader belts. We recommend a meticulous physical assessment of these bearings during every annual preventative maintenance check.
Upgrading to this high-performance agricultural bearing is a smart choice to save money on mid-season breakdown costs. Replacing a gritty or noisy bearing prior to harvest preserves the integrity of your vertical drive shafts, keeping your residue distribution system working in top condition for a trouble-free longer service life.
Installation Tip: Hex Shaft and Flange Check
When installing the new 195293C91 bearing, meticulously inspect the flat surfaces of the 7/8" hexagonal drive shaft for rounding, notches, or twisting. A compromised or loose hex shaft profile allows the bearing inner ring to slowly spin or "chatter" under heavy harvesting loads, resulting in intense friction and rapid shaft failure. Clean out the mounting flanges completely to ensure a perfectly aligned, high-strength mechanical seat.
