Description
The FAAC Z20 Pinion – 719167 is a genuine FAAC 20-tooth Module 4 drive pinion designed for compatible FAAC sliding gate operators using Module 4 gate rack.
The pinion mounts to the sliding gate operator’s output shaft and engages directly with the gate rack, transferring the rotational movement of the operator gearbox into linear movement of the sliding gate.
On compatible FAAC 844 installations, the Z20 pinion can also be used as a higher-speed alternative to the standard Z16 pinion, increasing the gate travel speed while changing the operator’s maximum gate weight and duty capabilities.
FAAC Part Number: 719167
⚙️ Genuine FAAC Z20 Drive Pinion
The 719167 is a genuine FAAC sliding gate operator drive pinion.
The Z20 designation identifies the pinion as having:
- 20 Teeth
- Module 4 Gear Profile
It is designed to engage with compatible Module 4 sliding gate rack.
🔩 20-Tooth Configuration
The Z20 pinion has 20 drive teeth.
Increasing the number of teeth compared with a Z16 pinion increases the distance the rack travels for each revolution of the operator output shaft.
This allows the Z20 to provide a higher gate travel speed on compatible operators.
🏎️ Higher Speed for Compatible FAAC 844 Operators
When fitted to a compatible FAAC 844 operator, the Z20 pinion increases the gate travel speed compared with the standard Z16 configuration.
Published Australian specifications identify:
- Z16 Speed: Approximately 9.6m/min
- Z20 Speed: Approximately 12m/min
The Z20 therefore provides approximately 25% greater linear gate speed compared with a Z16 pinion at the same output shaft speed.
This can be useful where a faster opening and closing cycle is required.
⚠️ Speed vs Gate Capacity
Increasing the pinion diameter and number of teeth changes the mechanical relationship between the operator and gate.
While the Z20 provides greater gate speed, it also reduces the amount of effective drive force available at the rack compared with the smaller Z16 pinion.
For this reason, fitting a Z20 pinion can change:
- Maximum permitted gate weight
- Gate speed
- Available drive force
- Operator duty capability
The complete gate installation must therefore be checked before replacing a Z16 pinion with a Z20.
🚧 FAAC 844 Application
The FAAC Z20 719167 is specifically listed by FAAC as an available pinion for compatible 844 sliding gate operators.
On compatible 844 configurations, the Z20 can be used where increased gate speed is required and the gate remains within the applicable operating limits.
Australian application information for the 844 identifies the Z20 configuration as providing approximately 12m/min gate speed.
🚪 FAAC 746 Application
FAAC also lists the 719167 Z20 pinion within the accessories for compatible FAAC 746 sliding gate operators.
Both the Z20 719167 and Z16 719130 are listed as pinion options within the 746 operator family.
The correct pinion must be selected according to the exact operator version and gate requirements.
🦷 Module 4 Rack Compatibility
The Z20 pinion is designed for use with compatible:
- Module 4 Sliding Gate Rack
FAAC offers several Module 4 rack configurations, including galvanised steel and reinforced nylon options for compatible installations.
The rack and pinion must have the same gear module to engage correctly.
🔄 Rack & Pinion Drive
The pinion is a critical component of the sliding gate drive system.
As the operator turns the pinion, the teeth engage with the fixed rack mounted along the gate.
This converts the operator’s rotary output into the linear movement required to:
- Open the sliding gate
- Close the sliding gate
Correct pinion and rack engagement is essential for smooth and reliable operation.
📐 Correct Rack Clearance
The gate rack should be correctly positioned relative to the Z20 pinion during installation.
The rack should not rest directly on the pinion.
Correct installation provides suitable clearance between the rack and pinion so the weight of the gate remains supported by the gate rollers and track rather than by the operator gearbox.
Correct alignment helps provide:
- Smooth operation
- Reduced operating noise
- Consistent tooth engagement
- Reduced pinion wear
- Reduced rack wear
- Reduced gearbox loading
🔧 Replacement Drive Pinion
The FAAC 719167 can also be used as a replacement Z20 pinion where an existing compatible pinion has become damaged or excessively worn.
Pinion replacement may be required if the existing component shows:
- Damaged teeth
- Excessive tooth wear
- Physical damage
- Poor rack engagement
- Damage resulting from incorrect rack alignment
The gate rack should also be inspected when replacing a damaged pinion.
🛠️ Check Rack Condition
Installing a new pinion against badly worn or damaged rack can result in poor engagement and accelerated wear.
When replacing the Z20 pinion, inspect the rack for:
- Damaged teeth
- Excessive wear
- Incorrect alignment
- Loose mounting points
- Incorrect rack height
- Excessive pinion clearance
- Insufficient pinion clearance
Any rack problems should be corrected before returning the gate to service.
🏭 Residential, Commercial & Industrial Applications
Depending on the compatible FAAC operator, the Z20 pinion can be used across a range of sliding gate applications.
These can include:
- Residential sliding gates
- Apartment complexes
- Commercial entrances
- Industrial sliding gates
- Factory entrances
- Warehouse entrances
- Car parks
- Controlled vehicle access gates
The operator and pinion configuration must remain suitable for the actual gate weight, length and required duty cycle.

⚠️ Please Note
This product is the genuine FAAC Z20 Pinion only.
FAAC Part Number: 719167
The sliding gate operator and gate rack are not included.
The Z20 pinion has 20 teeth and is designed for compatible Module 4 gate rack.
Changing from a Z16 to a Z20 pinion increases the gate travel speed but also changes the mechanical output of the operator. Maximum gate weight, available force and applicable duty cycle must therefore be checked before carrying out a Z20 conversion.
For applicable FAAC 844 configurations, Australian supplier information specifies approximately 12m/min gate speed with the Z20 pinion.
The rack must be correctly aligned with the pinion and must not place the weight of the gate onto the operator output shaft.
If replacing a worn or damaged pinion, inspect the gate rack for corresponding wear or damage before installing the replacement.
