Industrial Sprockets

Simplex Sprocket

Single-strand sprocket precision-machined to match ANSI and DIN standard roller chains. Available in 8T to 120T tooth count with custom bore and keyway.

8T – 120T Single Strand Custom Bore

Duplex Sprocket

Double-strand sprocket for duplex roller chains, offering higher load capacity in the same shaft space. Ideal for high-torque power transmission drives.

Double Strand High Torque Custom Bore

Industrial Sprockets

Triplex Sprocket

Triple-strand sprocket delivering maximum power transmission capacity. Used in heavy industrial drives where space is limited but load requirements are very high.

Triple Strand Max Load Capacity Heavy Duty

Manufacturing

Materials & Surface Finishes

Every sprocket is machined from quality-certified material and finished to your specification.

Mild Steel (MS)

IS 2062 grade mild steel. Most common and economical choice for general industrial drives in dry, non-corrosive environments.

General Purpose

Case Hardened Steel

Medium carbon steel with case hardening (HRC 55–62 on tooth flanks). Significantly extends wear life in high-speed, heavy-load drives.

Stainless Steel

SS304 and SS316 options for food processing, pharmaceutical and chemical industries where corrosion resistance is essential.

Food Grade

Cast Iron (CI)

Grey cast iron sprockets for large-diameter, slow-speed drives. Good vibration damping and economical for large tooth counts.

Large Diameter

Available Surface Finishes

Black Oxide Standard rust protection for indoor use

Zinc Plated Enhanced corrosion resistance

Phosphate & Oil Good rust protection with lubrication

Nickel Plated Decorative and corrosion resistant

Natural / Bare Unfinished for customer processing

Electropolished (SS) Hygienic finish for food applications

Design Guide

Sprocket Hub Styles

We manufacture sprockets in three standard hub styles. When placing an order, specify the hub style along with the bore diameter and keyway dimensions.

Style A — Flat / No Hub

Flat plate sprocket with no hub projection on either side. Used where axial space is very limited. Bore and keyway machined directly in the plate.

Style B — Single Hub

Hub extends on one side only (typically the back face). The most common configuration for standard shaft mounting with keyway and set screw.

Style C — Double Hub

Hub extends on both sides of the sprocket body equally. Provides maximum shaft engagement and stability for heavy loads and reversing drives.

Tooth Profile — matches chain roller diameter precisely

Pitch Circle Diameter — determines sprocket ratio

Bore & Keyway — custom-machined to your shaft size

Hub Length — Style A, B or C as required
