Sprockets

Industrial Roller Chain Sprocket Solutions & Sourcing

Sprockets are toothed power transmission components designed to engage roller chain and transmit rotational motion between shafts. Available in a wide range of sizes, tooth counts, hub styles, and materials, sprockets provide a reliable and efficient method of transferring power in industrial machinery and equipment. Proper sprocket selection helps maximize chain life, improve system efficiency, and reduce maintenance requirements in demanding operating environments. Weimer supplies a broad range of industrial sprockets to support power transmission, conveyor, and material handling applications across numerous industries.

Choosing the Right Sprocket

Selecting the correct sprocket helps maximize power transmission efficiency, extend chain life, and reduce maintenance costs. We can assist with identifying the proper sprocket for new equipment, replacement applications, and custom requirements.

Chain Size and Pitch – Sprocket chain pitch must match the roller chain for proper engagement and performance.
Hub Style – Available in A, B, and C styles, affecting mounting and machining options.
Number of Teeth – Determines the sprocket's size and affects drive ratio, speed, and performance.
Number of Strands – Single, double, triple, and multiple strand types.
Caliper Diameter – Diameter measured from tooth valley to tooth valley across the sprocket.
Outside Diameter (OD) – Overall diameter measured from tooth peak to tooth peak on the opposite side.
Maximum Bore Diameter – Largest bore size that can be machined without reducing sprocket strength.
Length Through Bore (LTB) – The length of the hub bore that supports proper shaft engagement and torque transmission.
Bore Configuration – Available as finished bore, plain bore, taper-lock, or QD bushed designs.
Material and Environment – Available in steel, stainless steel, cast iron, and specialty materials to suit the application.
Chain Standards – Available in ANSI and British Standard (BS) configurations to match corresponding roller chain sizes.

Types of Sprockets

From standard roller chain sprockets to specialty and custom-machined designs, Weimer provides solutions for a wide range of industrial power transmission applications.

Single Strand Sprockets

The most common sprocket style, designed for use with ANSI roller chain in a wide range of industrial applications.

Double Pitch Sprockets

Used with double pitch roller chain, often in conveyor and material handling systems requiring longer chain lengths.

Multiple Strand Sprockets

Designed to accommodate multiple strands of chain for higher horsepower and torque transmission.

QD and Taper-Lock Sprockets

Utilize removable bushings for easier installation, shaft mounting flexibility, and simplified maintenance.

Steel Split Sprockets

Split into two halves for quick installation and replacement without removing the shaft assembly.

Double Single Sprockets

Allow two separate chains to be driven from a common shaft, often in conveying and automation applications.

Idler Sprockets

Used to maintain chain tension, reduce chain whip, and guide chain travel.

Double Plus Sprockets

Designed for Double Plus conveyor systems where products move at higher speeds than the drive chain.

Engineering Class Sprockets

Designed for heavy-duty conveying and power transmission applications using engineering class chain

Stainless Steel Sprockets

Ideal for food processing, washdown, and corrosive environments where rust resistance is required.

Custom Machined Sprockets

Modified to customer specifications with custom bores, keyways, hub styles, and other special requirements.
