The 40 double-row 304 sprocket (standard model: D40-2 304SS) is a double-row stainless steel sprocket conforming to the ANSI #40 standard. It is manufactured from 304 austenitic stainless steel and is specifically designed for corrosion resistance, medium-to-light loads, and clean or humid environments. It is matched with the 40-2 double-row roller chain (pitch of 12.7 mm).

The pin sprocket is a specialized transmission/conveying sprocket that uses cylindrical pins as “teeth” to engage with chains or gears. It features a simple structure, high strength, excellent shock resistance, and easy replacement, making it widely used in heavy-duty, harsh-service equipment such as mining machinery, cement plants, scraper conveyors, bucket elevators, and heavy-duty plate-chain drives. It is classified as a large-pitch, heavy-load transmission component.
Typically, a greater number of teeth is used to reduce the polygon effect.
The assembly of the head pulley for an elevator involves assembling components such as the sprocket, main shaft, bearings/bearing housings, expansion sleeves (or keys), seals, and locating retaining rings into a complete drive wheel assembly in accordance with process requirements. This assembly serves as the core power-transmission unit for bucket elevators and plate-chain conveyors, directly affecting operational smoothness, sealing performance, and service life.

Medium-carbon steel and alloy steel, with case-hardened tooth surfaces for wear resistance and impact resistance.
Flaw Detection of Cement Head Conveyor Sprocket
Flaw detection of cement industry head drive sprockets is a nondestructive testing (NDT) procedure specifically designed for heavy-duty, actively driven sprockets at the heads of bucket elevators, plate-chain conveyors, and clinker conveyors in the cement industry. It is used to identify potential defects such as cracks, shrinkage cavities, inclusions, and heat-treatment-related flaws that are prone to occur under conditions of heavy loading, impact, high dust levels, and prolonged continuous operation. By doing so, it helps prevent tooth breakage, spalling, equipment downtime, and safety incidents, making it an essential step in factory acceptance inspections, major overhaul acceptance, and safety assessments of cement conveying equipment.
Non-standard sprockets refer to custom-designed sprockets whose tooth profile, structure, dimensions, and materials do not conform to national or industry standards. They are used to address operating conditions—such as space constraints, non-linear motion paths, heavy-load/high-speed applications, and corrosive environments—that cannot be met by standard sprockets.
The parking garage sprocket is the core transmission component of mechanical parking systems such as lift-and-shift and vertical-circulation systems. It drives the lifting and lateral movement of the vehicle-carrying platform, supports the weight of both the vehicles and the equipment, and is characterized by heavy-load capacity, low speed, and high safety.
The tail sprocket (also commonly referred to as the tail wheel, driven sprocket, or deflection sprocket) is a core driven component that is paired with the head drive sprocket and installed at the tail end of plate-chain conveyors, bucket elevators, clinker conveyors, and scraper conveyors in the cement industry. It is specifically designed for the harsh operating conditions of cement production, which involve high dust levels, heavy loads, continuous operation, and severe wear.
A duplex sprocket, also known as a double-row sprocket, is a coaxial, integral sprocket with two rows of teeth, used to drive a double-row chain or two parallel single-row chains.
