Description
When a shaft needs to stay put or you need a spacer that won’t budge, a solid steel collar is the answer. Whether you’re dealing with a loose pulley on your PTO-driven equipment, need proper spacing on a roller shaft, or want to keep a bearing in the right position, this little collar handles the job without fuss. It’s the kind of simple, reliable part that mechanics reach for when they need something that’ll hold tight and stay there.
Key Features
- 1/2 inch inside diameter fits standard half-inch shafts used throughout agricultural equipment
- Solid steel construction won’t crack or strip like cheaper alternatives under field conditions
- Zinc plating provides corrosion resistance for outdoor use and harsh farm environments
- Precision machined for smooth installation and consistent performance
- Set screw design allows secure positioning anywhere along a shaft
Built for Real Farm Work
This collar works on all kinds of agricultural machinery where you need shaft positioning control. Think PTO-driven equipment like mowers and balers where precise spacing matters, conveyor systems on grain handling equipment, or any rotating shaft assembly where components need to stay in their proper places. The half-inch bore size fits many common drive shafts found on farm implements and auxiliary equipment.
Made to Last
Farm equipment collars take a beating from vibration, weather, and the constant cycling that comes with seasonal use. The solid steel construction won’t fatigue like thin-wall alternatives, and the zinc plating keeps rust at bay even when exposed to moisture and fertilizer chemicals. This isn’t a part you’ll be replacing next season.
Installation Notes
Clean the shaft thoroughly before installation to ensure the collar sits flush and the set screw bites properly. Position the collar where needed and tighten the set screw gradually – over-tightening can damage threads or distort the collar. A drop of thread locker on the set screw keeps it from backing out under vibration.
