Original NICE ROA7 22×22×1000 mm Steel Gear Rack
The NICE ROA7 is an original NICE galvanized steel gear rack designed for compatible automatic sliding gate motors using a Module 4 / M4 pinion.
Official NICE documentation identifies ROA7 as an M4 galvanized steel rack measuring 22 × 22 × 1000 mm. Each section is 1000 mm / 1 meter long and multiple sections can be installed together according to the required sliding gate travel.
The rigid galvanized steel construction makes the ROA7 suitable for professional residential, commercial and industrial sliding gate installations where a compatible M4 steel rack is required.

Official NICE ROA7 Technical Specifications
| Brand | NICE |
| Model | ROA7 |
| Product Type | Sliding Gate Gear Rack |
| Gear Module | M4 |
| Material | Galvanized Steel |
| Dimensions | 22 × 22 × 1000 mm |
| Length | 1000 mm / 1 Meter |
| Official Factory Pack | 10 pieces |
| Application | Compatible M4 sliding gate automation systems |
Important: ROA7 Is M4
The NICE ROA7 uses a Module 4 / M4 gear profile.
The sliding gate motor must therefore use a compatible M4 drive pinion.
Do not mix an M4 rack with an M6 pinion.
ROA7 vs ROA8
| Model | Official Specification |
| ROA7 | M4 galvanized steel rack, 22 × 22 × 1000 mm |
| ROA8 | M4 galvanized steel rack, 30 × 8 × 1000 mm, supplied with screws and spacers |
Both ROA7 and ROA8 use an M4 tooth profile, but they have different physical dimensions and mounting arrangements.
ROA7 vs ROA81
| Model | Official Specification |
| ROA7 | M4, galvanized steel, 22 × 22 × 1000 mm |
| ROA81 | M6, galvanized steel, 30 × 30 × 1000 mm, weld-on type for RUA12 pinion |
ROA7 and ROA81 are not interchangeable because they use different gear modules.
ROA7 vs Nylon Rack
NICE also offers reinforced nylon rack options for compatible sliding gate installations.
| Model | Specification |
| ROA6 | M4 nylon with metal insert, 25 × 20 × 1000 mm, gates up to 500 KG |
| ROA66 | M4 reinforced nylon rack, 25 × 20 × 1000 mm, six fixing points, gates up to 800 KG |
| ROA7 | M4 galvanized steel, 22 × 22 × 1000 mm |
| ROA8 | M4 galvanized steel, 30 × 8 × 1000 mm |
No Official 4000 KG Rating for ROA7
The NICE ROA7 should not be advertised as a rack officially rated for sliding gates up to 4000 KG.
NICE's official product specification confirms:
- M4 gear profile
- Galvanized steel construction
- 22 × 22 × 1000 mm dimensions
It does not assign ROA7 a 4000 KG maximum gate-weight specification.
Use:
Suitable for compatible NICE sliding gate motors using an M4 pinion where ROA7 is specified for the installation.
Compatible NICE Sliding Gate Motors
ROA7 is used with compatible NICE sliding gate operators equipped with the appropriate M4 pinion.
Compatibility must be checked according to:
- Motor model
- Pinion module
- Gate weight
- Gate dimensions
- Duty cycle
- Installation requirements
NICE RUN Compatibility
NICE officially lists ROA7 and ROA8 as standard M4 rack options for compatible RUN sliding gate motors.
For example, NICE specifies that RUN is supplied with a Module 4 pinion for use with standard ROA7 and ROA8 racks.
RUN with RUA12 M6 Pinion
Some RUN installations can use the optional NICE RUA12.
RUA12 is a 12-tooth Module 6 / M6 pinion.
When RUA12 is installed, NICE specifies the ROA81 M6 rack, not ROA7.
Important RUN Selection
- Standard RUN M4 pinion → ROA7 or ROA8
- Optional RUA12 M6 pinion → ROA81
ROBUS Applications
ROA7 can be used with compatible NICE ROBUS sliding gate systems using an M4 pinion where the rack is appropriate for the installation.
Always confirm the exact ROBUS generation and pinion specification.
ROX Applications
ROA7 can also be considered for compatible M4 NICE sliding gate systems where its mounting profile is suitable.
For ROX installations, confirm the motor pinion and preferred rack type before installation.
Do Not Advertise ROA7 Specifically for TUB4000
The current product page lists NICE TUB4000 as a primary compatible motor.
I recommend removing this claim unless the exact TUB4000 installation documentation specifies ROA7.
TUB4000 is an extremely heavy industrial sliding gate operator for gates up to 4000 KG. That motor's 4000 KG rating must not be transferred to the ROA7 rack simply because both products are NICE accessories.
Motor Rating Is Not Rack Rating
A motor's maximum gate-weight capacity and a gear rack's specification are separate technical matters.
For example, a motor may be rated for 1500 KG or 2500 KG, but that does not automatically mean every rack listed near that motor has the same weight rating.
Correct Gear Module Is Essential
The rack teeth must correctly match the motor pinion.
- M4 rack requires M4 pinion
- M6 rack requires M6 pinion
Never install ROA7 M4 onto an M6 pinion.
Problems Caused by Wrong Rack Module
- Incorrect tooth engagement
- Excessive operating noise
- Rapid rack wear
- Pinion damage
- Gate jumping
- Gearbox overload
- Unreliable gate movement
Galvanized Steel Construction
The NICE ROA7 is manufactured from galvanized steel.
The galvanized finish helps protect the steel surface against corrosion during suitable outdoor gate installations.
Outdoor UAE Installation
For UAE installations, a more accurate product statement is:
Galvanized steel construction provides corrosion protection for suitable outdoor sliding gate installations when correctly installed and maintained.
Do not claim an unverified special certification for extreme UAE heat, humidity or dust.
One Meter Rack Section
Each NICE ROA7 section measures 1000 mm / 1 meter.
Multiple rack sections are normally required for a complete sliding gate.
How Many Rack Sections Are Required?
The required rack quantity depends on the total movement length of the sliding gate.
As a general installation principle, the rack must cover the complete motor pinion travel from the fully closed position to the fully open position.
Always allow enough rack length for correct engagement at both end positions.
Joining Multiple ROA7 Sections
When joining two rack sections:
- Keep the tooth pitch continuous
- Keep both sections at the same height
- Keep the rack parallel with gate movement
- Maintain correct pinion clearance
Correct Rack Alignment
The ROA7 must remain correctly aligned with the drive pinion throughout the complete gate travel.
A misaligned rack can cause excessive noise, vibration and wear.
Rack-to-Pinion Clearance
The gate must be supported by its wheels and track.
The rack must not rest heavily on the motor pinion.
Maintain the clearance specified in the sliding gate motor installation instructions.
Do Not Use the Motor to Carry Gate Weight
The motor pinion drives the gate horizontally.
It must not support the vertical weight of the gate.
If the rack is pressing heavily onto the pinion, inspect the gate wheels, rack height and motor mounting position.
New ROA7 Rack Installation
- Check that the gate moves freely by hand.
- Install and level the sliding gate motor.
- Release the motor for manual movement.
- Confirm the motor uses an M4 pinion.
- Position the first ROA7 rack section.
- Maintain correct pinion clearance.
- Secure the rack to the gate.
- Move the gate manually.
- Install the next rack section.
- Align the teeth correctly at the joint.
- Continue across the complete gate travel.
- Check rack alignment from fully closed to fully open.
- Check all fixing points.
- Recheck pinion clearance.
Replacing a Damaged ROA7 Section
Before replacing only one section of an existing steel rack, compare:
- Rack module
- 22 × 22 mm profile
- Tooth dimensions
- Mounting arrangement
- Existing rack height
- Motor pinion
Do not assume every manufacturer's M4 22 × 22 rack will join perfectly with an existing NICE ROA7 section.
Common Steel Rack Problems
- Loose mounting points
- Damaged gear teeth
- Rack misalignment
- Incorrect rack-to-pinion clearance
- Uneven rack joints
- Gate track problems
- Damaged gate wheels
- Loose motor foundation
Gate Makes a Knocking Sound
If the gate makes a knocking noise at regular positions, inspect the joints between rack sections.
A step or incorrect tooth spacing can cause the pinion to strike the rack at every joint.
Gate Is Noisy During Full Travel
Check:
- Rack alignment
- Pinion clearance
- Gate wheel condition
- Track alignment
- Motor mounting position
- Rack and pinion wear
Damaged Rack Teeth
Before replacing damaged rack teeth, identify why the damage occurred.
Possible causes include incorrect module, poor alignment, excessive gate resistance, impact damage or incorrect rack clearance.
