Description
Hangzhou Ever-Power Sprocket Co., Ltd.
We could tell you these sprockets are excellent. Instead, let’s start with what three production engineers reported after their first year of use.
Results Reported by Customers in the First Year
“Dairy conveyor ran 14 months straight after switching to 316 SS. Previously we had at least two corrosion-related stops per quarter.”
“We used to replace our #35 sprockets every 4 months. The SS units from Ever-Power are still in service at 13 months with no measurable tooth wear.”
“The MTR and CMM report that came with the shipment were the first time our incoming QC team approved a sprocket order without any additional verification. Everything checked out.”
What Makes These Results Possible
Consistent field results come from consistent manufacturing — and that starts well before the machining stage. Every #35 SS sprocket we produce begins with grade-verified bar stock (PMI-checked on delivery), machined on gear-hobbing equipment calibrated quarterly to laser ball-bar standards, and finished to Ra ≤ 1.6 µm on tooth contact faces. The bore is cut to H7 tolerance as standard — the same class used by tier-one OEM suppliers — so there is no fretting on the shaft, no movement under load, and no micro-cracking at the bore-shaft interface that causes hidden fatigue damage. These are not premium add-ons. They are how we make every sprocket.

The Grade Matters — Here Is How to Choose
Both 304 and 316 SS outperform carbon steel in corrosive environments, but the right choice depends on your specific cleaning protocol and process chemistry. Grade 304 handles alkali detergents, steam, and most organic acids well — and it costs less. Grade 316 adds molybdenum to resist chloride attack, making it the correct choice for any application using hypochlorite sanitizers, for seafood or meat processing where brine and blood acids are present, or for outdoor/marine installations. When in doubt, specify 316 — the cost difference between grades is much smaller than the cost of a premature replacement cycle.
Parts We Supply Alongside the Sprocket
The customers who see the best long-term results are the ones who build the entire drive in stainless — not just the sprocket. Mixing SS sprockets with carbon steel chain in a wet environment risks galvanic corrosion at the chain link contact. We supply matched stainless steel sprocket drive components:
- ANSI 35 SS Roller Chain — 304 and 316 grades, 10 ft and 25 ft lengths
- SS Master Links — spring-clip and cottered-pin types, matched grade
- Idler Sprockets — plain-bore and bearing-mounted for tensioning duties
- Taper-Lock Bush Sets — for rapid sprocket changeout on maintenance cycles
- NSF H1 Food-Grade Lubricant — PTFE dry-film spray compatible with SS chain
