If you're piecing together a power transmission line or a custom shaft setup, the silent make-or-break detail is often the collar or coupling that locks components in place. You need something that mounts cleanly, holds firmly, and doesn't scratch the shaft. The Face Flange Mounted Shaft Collar from Summit Collars & Industrial Supply, priced at $38.65, tackles exactly that with a straightforward hub-mount design.
Quick Verdict
This is a solid go-to for a 1-inch shaft application where you want mounting flexibility and a secure, mar-free hold. The collar's three tapped counterbored holes and three unthreaded holes give you multiple ways to attach it, and you can pick aluminum or black-oxide steel depending on whether you prioritize lightweight corrosion resistance or raw strength.
Who It Suits
Anyone who needs a simple, keyed shaft collar for a hub mount application. The standard ANSI keyway opens the door to use with keyed shafts, keys, and key stock, making it a practical pick for mechanical power transmission setups. It also suits those who care about shaft finish, because the clamping action holds evenly without scoring.
What Stands Out From the Listed Details
The first detail that stands out is the dual mounting pattern. Three tapped counterbored holes and three unthreaded holes in the face flange mean you can bolt it on from either side or adapt to different hardware without reworking the part. Second, the collar clamps evenly around the shaft, which is exactly what you want for a strong, mar-free grip. Third, the material choice matters: black-oxide steel offers more strength with some corrosion resistance, while aluminum is lightweight and offers good corrosion resistance.
Meaningful Trade-Offs
The main trade-off is strength versus weight and corrosion behavior. Go with black-oxide steel if the load demands it and you don't mind a heavier collar. Choose aluminum if you're watching weight and want good corrosion resistance, but understand that aluminum is typically not as strong as steel. Also note that the aluminum version has a black anodized finish, which adds a layer of protection and a clean look.
Bottom Line
For a well-priced, versatile 1-inch hub mount shaft collar, the Summit Face Flange Mounted Shaft Collar deserves a spot on your shortlist. It offers real mounting flexibility, a secure grip, and a choice of materials that lets you match the part to your environment.
Face Flange Mounted Shaft Collars Hub Mount Shaft Collar Couplings Alum or Steel
Priced at $38.65, this Summit Collars hub mount shaft collar comes in a 1-inch inside diameter and can be specified in aluminum black anodize or black-oxide steel. The three tapped counterbored holes and three unthreaded holes provide genuine mounting flexibility, and the even clamping around the shaft gives a strong, mar-free hold. If you're working with keyed shafts, the standard ANSI keyway is a clear advantage. The main limitation to keep in mind is the material trade-off: the steel version is stronger but heavier, while the aluminum version is lighter and more corrosion-resistant but not as strong. Choose based on your load and environment, not just the price.
