4. Spur Gears, Sprockets, and Chains

Any size spur gear, helical gear, chains, and sprockets for your equipment. Our forged steel gears and high-quality sprockets are hardened for maximum lifespan. (Chain-driven sprocket shown in the diagram).

Replacement Spur Gear

5. Complete Drums and Shell Sections

Complete drums and replacement shell sections rolled to precise standards to ensure absolute concentricity with your tires and existing shell sections.

10. Drive Motors

Finch can provide replacements for any existing motor and work with you to ensure you get the right size for your application for optimal efficiency.

11. Gear Reducers

We work with our customers to ensure that the provided motor and gearbox combination will be a 100% fit for your final drive needs while meeting all torque and power requirements. Finch supplies all types and sizes of reducers to meet your power, torque, and operating speed needs.

12. Auto Lubrication Systems

Auto lubrication systems reduce maintenance time and guarantee regular and accurate amounts of lubrication for the component. Finch partners with industry experts to ensure the best lubricant for your application. Set your lubrication interval and volume and let the system minimize downtime and increase the lifespan of your drive.


13. Pinions and Drive Sprockets

Forged steel pinions and high-quality sprockets to mate with your existing drum gear or drive chain. We can reverse engineer sprockets and pinions if you do not have a drawing.

Pinion Gear Assembly

14. Bearings

Finch supplies high-quality brand-name bearings to meet the needs of our customers. When faced with availability issues and long lead times, we use our expansive network of partners and vendors to find suitable alternatives. We machine custom bronze bushings for larger kilns and can pour and machine babbitt bearings.

15. Trunnions

Manufactured from the highest quality forged steel and heat treated to our custom specifications based on years of knowledge and experience. Our trunnions are built to last. Finch offers refurbishment services. The roller face is machined true, the shaft repaired or replaced, and the surface re-heat treated to ensure the same Finch quality while saving you money.
