Description
Hangzhou Ever-Power Sprocket Co., Ltd.
The ANSI B29.1 standard does not charge a premium for the Browning logo. Neither should you.
What You Are Actually Paying For With a Brand-Name Sprocket
When a procurement team specifies a Browning, Martin, or Tsubaki #40 stainless steel sprocket, they are paying for a product that meets ANSI B29.1 dimensional tolerances, is made from 304 or 316 stainless bar stock, and comes with a material certificate. These are legitimate requirements — and they are also exactly what the Ever-Power #40 Stainless Steel Sprocket delivers, in the same document format, to the same tolerance class, from the same type of certified bar stock. The difference is that Ever-Power operates from a Hangzhou facility where manufacturing overhead and logistics cost structures allow us to price significantly below the major catalogue brands while maintaining the technical specification that actually matters to engineers. The brand name is not part of the specification. The pitch diameter accuracy, the bore tolerance, the material grade, and the documentation are — and those are the same.

The Procurement Argument Your Engineering Team Will Back
The conversation between procurement and engineering about switching away from a brand-name sprocket supplier usually goes one of two ways: either engineering signs off on the equivalent spec and the switch happens smoothly, or engineering asks for a sample, installs it alongside the existing brand, and runs a parallel comparison over one maintenance interval. We welcome both approaches. Our H7 bore tolerance, ANSI B29.1 Class A tooth profile, and mill-certified material grade are verifiable claims — not marketing assertions — and any incoming QC team with standard gauges can confirm them on the first delivery. The documentation package we include (MTR + CMM report) is usually more complete than what the brand-name supplier provides, which often makes the engineering sign-off faster rather than slower.
Components We Supply for a Complete #40 SS Drive
The same value argument applies across the drive system. We supply matched components so you can consolidate your SS drive sourcing from one supplier and one quality system:
- ANSI 40 SS Roller Chain — 304 and 316 grades, single and double strand
- Taper-Lock Bushing Sets — 1008 through 3020 series
- 40H Heavy Series SS Chain — for drives approaching the upper power boundary
- SS Chain Guards — 1.5 mm 304 sheet metal, hinged inspection window
- A2-70 Fastener Sets — grade-matched SS set screws and cap bolts
What Customers Say After Making the Switch
“Our engineering team approved the switch in one week after seeing the CMM report. The sprockets installed without any rework. We’re saving around 40% on unit cost versus our previous Browning-equivalent order.”
“I was sceptical about switching from Tsubaki at first. The sample we received had tighter bore tolerance than some Tsubaki units in our inventory. We’ve now standardised on Ever-Power for all our #40 SS requirements.”
“Paperwork was actually better than what we used to get from Martin — MTR and CMM included without asking. Procurement loves the price. Engineering is happy with the quality. Rare to get both.”
