Aetna Idler Sprockets, Idler Pulleys & Power Transmission Components

Aetna idler sprockets and pulleys form critical components in power transmission systems across manufacturing, maintenance, and mining operations. Proper idler selection ensures optimal belt tension, reduces system downtime, and extends overall component life. Our range encompasses single and double pitch sprockets, flanged and non-flanged pulleys, and specialised variants with zinc-plating for corrosion resistance.

Each product accommodates standard ANSI roller chain, double pitch conveyor chain, and multiple belt profiles, with bore sizes and load ratings matched to existing Australian industrial equipment specifications. Whether managing light-duty precision machinery or heavy-duty production conveyors, Aetna solutions deliver reliable performance across demanding operational environments.

Aetna Idler Sprockets — Single & Double Pitch

Aetna idler sprockets deliver precision tensioning across ANSI roller chain, double pitch conveyor chain, and specialised chain applications. Single pitch sprockets maintain consistent chain alignment in power transmission systems, whilst double pitch variants reduce component count and cost across extended conveyor runs. Each sprocket type offers multiple bore sizes, material options, and load ratings — enabling specification into existing Australian industrial equipment without modification.

• Aetna Single Pitch Idler Sprocket: A precision single pitch idler sprocket engineered for ANSI roller chain and standard pitch conveyor systems. Features hardened teeth for extended service life under repetitive tensioning cycles, with precision bore tolerance for smooth operation and minimal runout. Bore sizes accommodate various shaft diameters across light to medium-duty applications.
• Aetna Single Pitch Idler Sprocket (Yellow Zinc Plated): The zinc-plated variant offering enhanced corrosion resistance in washdown environments, food processing, and coastal industrial installations. Yellow zinc coating provides both decorative finish and long-term protection against rust development. Enables direct substitution where environmental exposure demands additional corrosion protection. Applications include beverage production, meat processing, agricultural equipment servicing, and coastal maintenance facilities experiencing accelerated corrosion patterns on standard steel.
• Aetna 1-1/4" Double Pitch 9T x 7/8" ID Idler Sprocket: A double pitch variant designed for use with double pitch conveyor chain systems. The 1-1/4" pitch and 9-tooth configuration suit heavy-duty conveyor lines moving bulk materials and palletised goods. Double pitch systems reduce component count and offer cost advantages across extended conveyor runs.
• Aetna Heavy Duty Double Pitch Idler Sprocket: Heavy duty construction engineered for applications with higher chain tensions, longer runs, and demanding production environments. Enhanced tooth thickness and reinforced hub design improve fatigue resistance in mining operations, bulk material handling, and high-tonnage conveyor systems. Maintains double pitch compatibility whilst delivering superior load capacity versus standard variants. Recommended for applications where component replacement costs or operational downtime justify premium component investment.
• Single Pitch Idler Sprocket (Extra Heavy Gauge Steel): Extra-heavy-gauge construction for high-load chain drive applications and severe-duty tensioning requirements. Thicker steel throughout sprocket structure and hub resists bending deflection under sustained high tension. Accommodates shock loading and sudden acceleration in mining operations, mobile crushing equipment, and refuse handling systems. Ideal where component failure creates safety risks or extended downtime. Enhanced material properties deliver improved yield strength supporting maximum-load operation.
• Sprocket Idler — Detachable Chain Idler: Designed specifically for detachable link chain systems with tooth profiles compatible with roller block designs. Enables rapid chain disassembly for cleaning, maintenance, and product changeovers without disturbing overall conveyor structure. Common in food processing, pharmaceutical manufacturing, and hygiene-critical applications. Maintains consistent tension throughout detachable chain runs whilst accommodating slightly different wear characteristics compared to standard ANSI chain systems.

Aetna Idler Pulleys — Flat Belt, V-Belt & Round Belt

Aetna idler pulleys span flat belt, V-belt, and round belt drive systems, accommodating light-duty precision machinery through heavy-duty production conveyors. Flanged and non-flanged variants address different belt alignment and installation requirements. Zinc-plated options provide enhanced corrosion resistance in washdown and outdoor environments. Load ratings, bore sizes, and belt compatibility information enable direct specification into existing drive systems.

• Idler Pulley Flat Flanged: A single row flanged flat belt idler for maintaining belt alignment and tension in conveyor belt systems. The flanged edges prevent belt run-off in installations with misalignment or side loading, common in aggregate, food processing, and general conveying applications.
• Idler Pulley Flat Flanged Double Row Zinc Plated: The double row zinc-plated variant providing extended bearing life under higher radial loads and corrosion resistance for moist, washdown, or food industry environments where single row bearings have insufficient capacity.
• Idler Pulley Flat Non Flanged Double Row: A non-flanged flat belt idler for installations where belt tracking is managed by the conveyor frame geometry rather than pulley flanges. Double row bearings are specified for higher load and longer service interval applications.
• Aetna Idler Pulley Flat Non Flanged (2-3/4" OD x 1/2" ID x 1-1/2"): A compact imperial-dimensioned non-flanged idler for light-duty flat belt applications. Suited to packaging machinery, bottling lines, and small conveyor systems built to inch specifications.
• Idler Pulley A/B/C Section V-Belt 4 Point Heavy Duty: A heavy-duty idler pulley designed for A, B, and C section V-belts. The four-point contact configuration provides superior belt engagement and is used in high-torque drive systems including agricultural machinery, compressors, and large fan drives.
• Idler Pulley A Section V-Belt 4 Point Heavy Duty: Configured specifically for A section V-belts in smaller centre distance drive systems where belt tension management is critical to drive efficiency. The four-point heavy duty design extends idler life in high-cycle applications.
• Idler Pulley B Section V-Belt Single Row: A standard single row idler for B section V-belts, used across general power transmission applications including pumps, fans, compressors, and industrial machinery where a B section belt is the primary drive element.
• Aetna Idler Pulley Round Belt: An idler pulley for round belt drives, used in lighter power transmission and conveyor applications including food processing equipment, textile machinery, and small appliance assembly systems where round belts are preferred for their self-tracking properties.
• Aetna Rubber Tyre Idler (4-1/4" OD x 1/2" ID x 7/8" Wide): A rubber tyre idler for noise-sensitive and vibration-attenuating applications. The rubber interface absorbs impact and reduces noise transmission between the belt and idler, suited to high-speed light conveyor systems in production and packaging environments.
