Sliding gate gear rack FAAC SP157 – replacement rack for sliding gates

Gear rack FAAC SP157 is a replacement rack designed for use with FAAC sliding gate operators. It provides the toothed segment that meshes with the gate motor pinion to enable linear movement of sliding gates. Intended for repair and maintenance of automatic sliding gates, this rack restores drive engagement and helps to recover smooth gate operation without modifying the existing motor or pinion.

Advantages

The FAAC SP157 gear rack is manufactured to match the tooth profile and pitch required by compatible FAAC sliding gate motors, ensuring consistent meshing and reduced backlash. Its design supports straightforward installation and direct replacement of worn or damaged sections, which can extend the service life of the gate drive system. The rack material and machining provide stable contact with the motor pinion, helping to reduce noise and uneven movement.

Suitable for

• Repairing worn or damaged gear rack segments on FAAC sliding gate systems
• Maintenance replacement during routine servicing of automatic sliding gates
• Restoring engagement between gate motor pinion and rack after mechanical wear
• Use in residential and light-commercial sliding gate installations

Key specifications

• Form: straight toothed rack segment suitable for sliding gate drives
• Compatibility: intended for use with FAAC sliding gate operators requiring matching rack profile
• Function: transmits rotational motion of the motor pinion into linear gate movement
• Construction: machined/formed teeth for accurate engagement with the pinion

How to use

Install the replacement FAAC SP157 rack by aligning the teeth with the motor pinion and securing the rack to the gate frame or guide rail according to the gate manufacturer’s mounting points. Ensure the gate is supported and immobilized during replacement to avoid movement while fitting. After mechanical installation, check meshing along the full travel, adjust lateral position if necessary to eliminate binding or excess clearance, and perform several test cycles at low speed to verify smooth engagement before returning the gate to normal operation.

Usage recommendations

For reliable operation, inspect adjoining components such as the motor pinion, mounting brackets, and guide rails when replacing the rack. Replace any worn pinion or damaged mounting hardware to ensure correct engagement. Apply corrosion protection or recommended lubricant sparingly on teeth only if specified by the gate operator manufacturer; excessive lubrication can attract debris and accelerate wear.
