Descrição
Hangzhou Ever-Power Sprocket Co., Ltd.
ANSI 40 stainless steel sprockets — designed for heavy-duty chain drives where corrosion and hygiene standards cannot be compromised.
Visão geral do produto
Among all ANSI chain sizes, the #40 pitch (12.7 mm) is the most widely used standard in industrial machinery globally — making the Ever-Power #40 Stainless Steel Sprocket our single highest-volume product family. Machined to ANSI B29.1 tolerances with gear-hobbed tooth forms that guarantee smooth chain engagement, these sprockets are available across a tooth-count range of 9T to 96T to satisfy everything from high-speed small-diameter drives to large-diameter slow indexers. Whether your plant engineering team specifies 304 SS for cost-efficiency or 316 SS for an aggressive chemical environment, we hold both grades in stock and can ship standard bore sizes within 5 working days.
Especificações técnicas
ANSI 40 chain pitch is 12.7 mm (1/2 inch), roller diameter 7.92 mm, inner width 7.85 mm. These are the most common dimensions in the global chain-drive industry, making replacement and spare-part sourcing straightforward. Our #40 SS sprockets are manufactured to tolerance class A as defined in ANSI B29.1.

Hub Styles Explained
Selecting the right hub style for your application is as important as choosing the correct tooth count. Understanding the ANSI hub type system prevents installation errors:
No hub projection. Used where axial space is tight or where the sprocket mounts directly to a flange or disc.
Hub projects to one side only. The most common general-purpose configuration — positions the chain centerline close to a bearing.
Hub projects both sides. Best for long-bore applications and shafts that require maximum engagement length for torque transfer.
Aplicações industriais
The #40 pitch is the workhouse of industrial chain drives. Our roda dentada de aço inoxidável for ANSI 40 chain finds service in sectors as diverse as chemical plant dosing systems, poultry processing conveyor lines, commercial laundry equipment, offshore drilling deck machinery, and automotive paint-shop conveyors. Wherever the environment would corrode a standard steel sprocket within a service interval, stainless is the only practical answer.
| Indústria | Aplicativo | Material Choice |
|---|---|---|
| Poultry / Meat | Evisceration conveyor | 316 SS (blood acids) |
| Chemical Processing | Reagent drum conveyor | 316 SS (acids/alkalis) |
| Automotive Paint | Overhead monorail | 304 SS (humidity) |
| Offshore / Marine | Deck winch drive | 316 SS (saltwater) |
Our Manufacturing Capabilities
Our Hangzhou facility operates 24 gear-hobbing machines and 18 CNC turning centres, giving us the capacity to produce over 50,000 sprockets per month across all chain sizes. In-house heat treatment — solution annealing for maximum corrosion resistance and selective induction hardening for high-wear tooth faces — means we control every process variable without sub-contracting. Each batch is documented with a full production traveller that accompanies the shipment: material grade, heat lot, machining date, inspection results, and operator sign-off.

Avaliações de clientes
“We switched our poultry line conveyor to Ever-Power 316 SS #40 sprockets two years ago. Zero corrosion, zero tooth breakage. We’ve extended the planned maintenance interval from 3 months to 8 months.”
“Custom 72T sprockets delivered in 14 days with full dimensional inspection report. The quality is on par with what we used to buy from Martin at nearly double the price.”
“Decent quality and quick response to our RFQ. The keyway was cut to spec — no rework needed. Would like more standard stock items held for same-week dispatch.”
