Original NICE ROA8 30×8×1000 mm Steel Gear Rack
The NICE ROA8 is an original NICE galvanized steel gear rack designed for compatible automatic sliding gate systems.
Official NICE documentation specifies the ROA8 as an M4 galvanized steel rack measuring 30 × 8 × 1000 mm and supplied with screws and spacers for installation.
The rigid galvanized steel construction makes ROA8 suitable for professional residential, commercial and industrial sliding gate installations where a robust M4 rack is required.
Each rack section is 1000 mm / 1 meter long. Multiple sections can be installed in sequence to cover the full gate travel.

Important: ROA8 Is M4
The NICE ROA8 uses a Module 4 / M4 tooth profile.
It must be matched with a compatible M4 motor pinion.
Do not confuse it with the NICE ROA81, which is an M6 rack.
ROA8 vs ROA81
| Model | Specification |
| ROA8 | M4, galvanized steel, 30 × 8 × 1000 mm, supplied with screws and spacers |
| ROA81 | M6, galvanized steel, 30 × 30 × 1000 mm, welding type, used with RUA12 pinion |
ROA8 and ROA81 use different gear modules and must not be interchanged.
ROA8 vs ROA7
NICE also offers the ROA7 M4 galvanized steel rack.
- ROA7 – M4, 22 × 22 × 1000 mm galvanized steel
- ROA8 – M4, 30 × 8 × 1000 mm galvanized steel with screws and spacers
Both are M4, but their physical profiles and installation methods differ.
ROA8 vs NICE Nylon Rack
For lighter residential installations, NICE also offers reinforced nylon rack models.
| Model | Type |
| ROA6 | M4 nylon with metal insert, 25 × 20 × 1000 mm, officially rated up to 500 KG |
| ROA66 | M4 nylon with metal insert and six fixing points, officially rated up to 800 KG |
| ROA8 | M4 galvanized steel, 30 × 8 × 1000 mm |
No Official 1200 KG Rating for ROA8
Your current product page states that the ROA8 rack is suitable for gates up to 1200 KG.
The official NICE catalogue specification for ROA8 confirms the rack module, dimensions, galvanized construction and included screws/spacers, but it does not specify a 1200 KG maximum gate-weight rating.
For accurate product information, remove the fixed 1200 KG claim.
Use:
Suitable for compatible M4 sliding gate motors and applications where ROA8 is specified for the motor and gate installation.
Compatible NICE Sliding Gate Motors
NICE lists ROA8 as an accessory across several sliding gate product families.
Compatibility depends primarily on:
- M4 pinion compatibility
- Motor model
- Gate weight
- Gate duty cycle
- Installation geometry
NICE ROBUS Applications
NICE currently lists ROA8 among completion accessories for ROBUS sliding gate systems.
This includes suitable new ROBUS installations using an M4 pinion.
NICE ROX Applications
NICE's official ROX kit brochure also lists ROA8 as a sliding gate rack accessory.
Therefore, ROA8 is a valid NICE rack option for compatible ROX installations.
NICE RUN Applications
NICE technical installer documentation includes ROA8 among the selectable rack options for RUN installations using the compatible M4 pinion configuration.
Some heavy-duty RUN installations may use the optional RUA12 M6 pinion with ROA81 M6 rack. Always check the exact pinion fitted before ordering.
Do Not List THOR Automatically
Your current page lists the NICE THOR series as compatible.
Before keeping THOR in the compatibility list, verify the exact THOR motor pinion and rack specification.
A safer generic statement is:
Compatible with NICE sliding gate operators using the correct M4 pinion and ROA8 rack specification.
Remove NICE ACER Series
Your current page lists NICE ACER Series.
ACER is not a NICE sliding gate motor family. LIFE ACER is a separate manufacturer/product family.
Remove NICE branding from ACER on this page.
If you want to mention third-party compatibility, use:
May also fit selected non-NICE sliding gate motors using a matching M4 pinion; dimensions and tooth profile must be verified before installation.
Correct Rack Module Is Essential
The motor pinion and gear rack must use the same gear module.
- M4 pinion → M4 rack
- M6 pinion → M6 rack
Never mix M4 and M6 parts.
Why M4 Compatibility Matters
If the rack and pinion modules do not match:
- Gear teeth will not mesh correctly
- Movement can become noisy
- Rack or pinion teeth can wear rapidly
- The gate can jump during movement
- The motor gearbox can be overloaded
Galvanized Steel Construction
The NICE ROA8 is manufactured from galvanized steel.
Galvanizing helps protect the steel surface against corrosion during normal outdoor use.
However, installation quality and local environmental conditions still affect service life.
Do Not Claim Unlimited UAE Weather Resistance
Your current page says the rack is designed for extreme UAE heat, dust and humidity.
I recommend replacing this with a more accurate statement:
Galvanized steel construction provides corrosion protection for suitable outdoor sliding gate installations when correctly installed and maintained.
Supplied with Screws and Spacers
NICE officially states that ROA8 is supplied complete with screws and spacers.
Your live page currently says screws and nuts.
Change this to:
Supplied with screws and spacers.
Rack Mounting
The included spacers position the rack correctly away from the gate structure and help provide adjustment during installation.
The exact mounting arrangement should follow the gate construction and motor installation instructions.
Correct Rack-to-Pinion Clearance
The gate weight must be carried by the gate wheels and track, not by the motor pinion.
Correct clearance should be maintained between the rack and pinion across the full gate travel.
If the rack is mounted too tightly against the pinion, gearbox load and operating noise can increase.
Rack Alignment
The ROA8 should remain straight and aligned with the motor pinion from the fully closed position to the fully open position.
Check alignment at every mounting point.
Joining Multiple 1 Meter Sections
Long sliding gates require multiple ROA8 sections.
The sections must be installed so that:
- Tooth pitch remains continuous
- There is no height step at the joint
- The rack remains parallel with the gate movement
- The correct pinion clearance is maintained
Use a Rack Section as an Alignment Guide
When joining two gear rack sections, a spare rack or matching tooth section can be used as an alignment guide to maintain the correct tooth pitch across the joint.
New Sliding Gate Installation
- Make sure the gate rolls freely by hand.
- Install and level the gate motor.
- Unlock the motor.
- Position the first ROA8 section over the pinion.
- Maintain correct rack-to-pinion clearance.
- Secure the first rack section.
- Move the gate manually.
- Add the next rack section.
- Keep the teeth correctly aligned at the joint.
- Continue across the entire gate travel.
- Check rack height and alignment.
- Recheck clearance from fully closed to fully open.
Replacing a Damaged Steel Rack
Before replacing only one section of an existing rack, compare:
- Gear module
- Rack profile
- Tooth size
- Mounting method
- Spacer height
- Existing pinion
Do not assume every 30 × 8 mm rack from another manufacturer will join perfectly with ROA8.
Common Steel Rack Problems
- Loose rack screws
- Incorrect rack height
- Damaged teeth
- Corrosion at cut or damaged areas
- Misaligned rack sections
- Incorrect clearance
- Gate track problems
- Loose motor foundation
Gate Makes Knocking Noise
If the gate makes a regular knocking sound, inspect the joints between rack sections.
A step or incorrect tooth spacing at one joint can cause the pinion to strike the rack every time it passes that point.
Gate Is Noisy Along Full Travel
Check:
- Pinion-to-rack clearance
- Rack alignment
- Gate wheel condition
- Track straightness
- Motor base alignment
Broken Rack Teeth
If teeth are damaged, identify the cause before fitting a replacement rack.
Possible causes include:
- Mismatched rack and pinion module
- Gate impact
- Poor rack alignment
- Excessive mechanical resistance
- Incorrect rack clearance
Do Not Use the Rack to Support the Gate
The rack is a drive component only.
The gate must be supported by its wheels, rollers and track system.
