Description
When you’re rebuilding or extending a PTO driveshaft, getting the right inner profile tubing can mean the difference between smooth power transfer and constant headaches. This trilobe-shaped inner tubing is built specifically for Bondioli Series 1 applications, giving you the precise fit and durability you need to keep your implements running strong season after season.
What You’re Getting
- Trilobe inner profile design provides three-point contact for smooth power transmission and reduced wear
- Heavy-duty construction with 0.138-inch wall thickness handles high torque applications without twisting
- Precision machined dimensions ensure proper telescoping action in your driveshaft
- 39-inch length gives you plenty of material for most standard and custom applications
- Quality Weasler manufacturing means it’ll mate perfectly with Series 1 outer tubes
Built for Real Farm Work
This tubing is designed for tractors running PTO-driven implements like balers, mowers, tillers, and post hole diggers. The trilobe profile distributes load evenly across three contact points instead of just two, which means less stress concentration and longer service life when you’re pushing your equipment hard.
Made to Last
With its 26.5mm outside diameter and robust wall thickness, this tubing won’t collapse under load or wear out prematurely from the constant telescoping action of field work. The steel construction handles the punishment of heavy implements and rough terrain without missing a beat.
Good to Know
This is inner profile tubing, so it slides inside the outer tube of your driveshaft assembly. Make sure you’ve got the right Series 1 outer tube to match, and always check your measurements twice before cutting to length. A little grease on the contact surfaces during assembly keeps everything sliding smoothly.
