Description
ATA 43T Nylon Sprocket Kit – 92236
The ATA 43T Nylon Sprocket Kit – 92236 is a genuine Automatic Technology commercial door component designed to provide a 43-tooth drive sprocket and drum adaptor assembly for compatible industrial roller door and roller shutter installations.
The kit mounts the large 43-tooth nylon sprocket directly to the roller door drum assembly, providing the driven sprocket required to transfer power from the commercial door operator through the drive chain to the roller door.
Supplied as a complete drum adaptor pack, the kit includes the 43T sprocket, retaining collar and associated mounting hardware required for installation.
⚙️ 43-Tooth Drive Sprocket
At the centre of the 92236 kit is ATA’s 43-tooth 10B nylon/plastic sprocket.
The sprocket forms the driven side of the operator’s chain-drive system.
When connected to the drive sprocket on the commercial operator by the appropriate chain, rotation from the operator is transferred to the roller door axle and drum assembly.
The 43-tooth configuration provides the required mechanical reduction for compatible ATA commercial roller door applications.
🔩 Drum-Mounted Installation
The 92236 sprocket kit is designed to mount directly to the end of a compatible roller door drum assembly.
ATA’s installation procedure positions the 43T sprocket at the end of the axle and drum, with the supplied adaptor hardware securing the sprocket to the drum assembly.
The sprocket must be correctly positioned and aligned with the operator drive sprocket to ensure smooth chain operation.
🔗 Commercial Chain-Drive System
The sprocket forms part of the mechanical transmission between the commercial door operator and the roller door.
The basic drive arrangement consists of:
Commercial Operator → Drive Sprocket → Drive Chain → 43T Drum Sprocket → Roller Door Drum
This provides a robust mechanical drive arrangement suitable for commercial and industrial roller door automation.
🏭 Commercial & Industrial Applications
The ATA 43T Sprocket Kit is intended for compatible commercial roller door and roller shutter installations.
Typical applications can include:
- Commercial roller doors
- Industrial roller doors
- Roller shutters
- Warehouse doors
- Factory entrances
- Workshop doors
- Commercial vehicle entrances
- Storage facilities
- Industrial buildings
- Commercial access doors
The complete drive configuration must be correctly selected according to the operator and roller door installation.
🛠️ Complete Sprocket Adaptor Pack
Part number 92236 is supplied as a complete sprocket drum adaptor pack rather than simply the nylon sprocket by itself.
According to ATA’s installation documentation, the kit contains:
- 1 × 43T 10B Nylon/Plastic Sprocket
- 1 × Sprocket Adaptor Hardware Pack
- 1 × Retaining Collar Kit
- 6 × M10 Flat Washers
- 3 × M10 Spring Washers
- 3 × M10 × 40 Hex Head Screws
- 3 × M10 Hex Serration Flange Nuts
- 3 × M10 Nyloc Nuts
- Installation instructions
This provides the core components required to mount the sprocket to the compatible roller door drum.
🔧 Retaining Collar Included
The kit includes ATA’s retaining collar assembly.
During installation, the retaining collar is fitted to the roller door axle and secured using its set screw.
Its purpose is to help prevent unwanted end movement of the axle assembly and correctly locate the sprocket installation.
🔩 Heavy-Duty M10 Mounting Hardware
The 43T sprocket is secured using three M10 mounting points.
The supplied hardware includes:
- M10 × 40 hex head screws
- Flat washers
- Spring washers
- Flange nuts
- Nyloc nuts
This provides a secure mechanical connection between the sprocket and compatible drum assembly.
📐 Adjustable Sprocket Alignment
Correct sprocket alignment is essential on a chain-driven commercial door operator.
ATA’s installation procedure allows the supplied washers and mounting hardware to be used as required to correctly position the 43T sprocket in relation to the operator sprocket.
The two sprockets should be accurately aligned so the drive chain runs straight between them.
Correct alignment helps provide:
- Smooth chain travel
- Reduced sprocket wear
- Reduced chain wear
- Lower operating noise
- Reliable power transmission
- Reduced risk of chain derailment
⛓️ Designed for 10B Chain Systems
The supplied sprocket is identified by ATA as a 43T 10B sprocket.
This means the sprocket is designed around the corresponding 10B chain profile used in the compatible commercial drive system.
The correct chain and operator sprocket must be used to maintain proper engagement with the 43T drum sprocket.
💪 Mechanical Reduction
Using a larger driven sprocket at the roller door drum provides mechanical reduction between the operator and the door.
The actual reduction ratio depends on the number of teeth on the operator drive sprocket compared with the 43 teeth on the drum sprocket.
This gearing arrangement allows the operator system to balance:
- Door operating speed
- Available torque
- Starting load
- Door size
- Mechanical load
The complete sprocket ratio should always match the requirements of the operator and roller door.
🔄 Smooth Power Transfer
When correctly installed and aligned, the 43T sprocket provides a reliable mechanical connection between the operator and roller door.
The chain-drive arrangement transfers rotational movement from the operator to the roller door drum, allowing the curtain to open and close.
Correct chain tension and sprocket alignment are essential for reliable operation.
🔧 Replacement & New Installations
The ATA 92236 kit can be used as part of a compatible new commercial door operator installation or when replacing the 43T drum sprocket and associated mounting components on an existing compatible system.
When replacing an existing sprocket, check:
- Existing sprocket tooth count
- Chain size
- Operator model
- Drive sprocket configuration
- Drum construction
- Existing mounting arrangement
- Required reduction ratio
before ordering.
