Description
Hangzhou Ever-Power Sprocket Co., Ltd.
You are not buying from a trading company that farms work out to whoever has capacity this week. You are buying from the plant that makes it, with 24 dedicated gear-hobbing machines, in Hangzhou, China.
Why Factory-Direct Matters for Large-Pitch Stainless Sprockets
The #80 pitch sprocket is not a commodity item. The large tooth form, the heavy stainless billet, and the precision required to hold pitch accumulation errors within class A tolerances across a high tooth count make this a part that benefits enormously from vertical manufacturing integration. When you buy from a trading company that subcontracts to whichever shop is available, you lose visibility into material sourcing, tooling condition, machine calibration, and inspection protocol. When you buy from Hangzhou Ever-Power, all of that happens in one facility under one quality management system — and we can tell you exactly which machine made your sprocket, which cutter was used, and when it was last calibrated. That traceability is not just a quality-system nicety. For heavy industrial buyers in petrochemical, paper milling, and offshore equipment, it is a procurement requirement.

No Subcontracting — Why That Matters to You
Industrial buyers sourcing from China often discover that the “manufacturer” they contacted is actually a trading company that places orders with two or three different workshops depending on who has capacity. This introduces variability between batches, inconsistent tooling, and broken traceability chains. Every #80 SS sprocket from Ever-Power is produced start-to-finish within our Hangzhou factory walls — billet receipt, PMI check, turning, hobbing, heat treatment, polishing, inspection, and packing. The production traveller that ships with your order tracks every step and every operator sign-off, creating a complete chain of custody from raw bar to your receiving dock. For buyers who have experienced batch-to-batch inconsistency from other Chinese suppliers, this is usually the decisive factor.
Components from the Same Factory, Same Quality System
Our large stainless steel sprockets are available alongside matching drive components for complete system sourcing from one supplier:
- ANSI 80 SS Roller Chain — 304 and 316 grades, single and duplex strand
- 80H Heavy Series SS Chain — for drives operating at peak single-strand capacity
- QD and SDS Taper Bushings — in SS for planned maintenance changeout
- Custom 316 SS Drive Shafts — turned with keyways and shaft collars
- Laser Alignment Tools — for precise chain-line setup after installation
What Customers Report After Factory-Direct Sourcing
“Three consecutive orders — all within tolerance, all with matching documentation. Previous supplier had batch-to-batch bore variation that required hand-fitting. Not an issue with Ever-Power.”
“Split-hub #80 SS sprockets for our overhead slaughterhouse conveyor. Delivered in 16 days with complete documentation. Fit perfectly — no adjustment required. The production traveller gave our QA team everything they needed.”
“Good quality and accurate. The factory-direct pricing versus what we were paying through a European distributor for equivalent quality was the real surprise. Significant saving.”
