70 mm 2 in 1 double gate roller

Product Description

70 mm 2 in 1 double gate roller

The 70mm 2-in-1 double gate roller set is a complete sliding gate hardware kit. It combines two 70mm load-bearing wheels and two guide rollers into one comprehensive package.

The “double” designation refers to the two distinct wheel types working together. The 70mm wheels carry the gate’s weight as it slides along the track. The smaller guide wheels maintain lateral alignment and prevent the gate from derailing or swaying during operation.

The 70mm load wheels are available in V-groove or U-groove profiles. This ensures compatibility with various sliding gate track systems. The guide wheels run along the track’s side, keeping the gate stable and preventing lateral movement.

This complete set is suitable for residential driveway gates, automated motor gates, commercial security entrances, and industrial sliding door systems.

What Is Included in a 70mm 2-in-1 Double Gate Roller Set?

A complete set typically includes all hardware necessary for a sliding gate installation or repair.

It includes load-bearing wheels, which are 70mm V-groove or U-groove wheels with double bearings. It includes guide wheels, which are smaller alignment rollers measuring 40mm x 40mm. It includes mounting hardware such as bolts, nuts, and washers as required.

The complete 4-piece set provides everything needed for proper gate support and alignment.

What Are the Key Specifications for 70mm Double Gate Rollers?

For U-groove models, the wheel diameter is 70mm. Groove type is U-groove. Wheel material is zinc-plated steel. Bearing type is double bearing. Load capacity per wheel is 220kg. Maximum gate load for two wheels is up to 440kg. Finish is gold or zinc-plated. Mounting type is internal bracket.

For V-groove twin wheel models, the wheel diameter is 70mm. Groove type is V-groove. Wheel material is steel. Bearing type is double bearing. Maximum gate load is up to 500kg or more. Guide roller size is 30 x 40mm. Finish is yellow zinc. Mounting type is bolt-on.

For the 2-in-1 complete set, the wheel diameter is 70mm. Groove type is typically V-groove. Maximum gate load is up to 800kg. Guide roller size is 40 x 40mm. Finish is multicolour. Mounting type is bolt-on.

What Are the Advantages of a Complete 2-in-1 Roller Set?

Purchasing a complete set rather than individual components offers several benefits.

Matched components mean the load wheels and guide wheels are designed to work together for optimal tracking and stability. A complete solution includes both wheels for carrying the gate and rollers for guiding it in one package, ensuring proper compatibility.

Easy installation means all necessary hardware is included, with no need to source separate parts. Cost-effectiveness means buying a complete set is often more economical than purchasing wheels and guides individually.

High load capacity means complete sets can support gates up to 800kg, suitable for residential and light industrial applications.

What Groove Types Are Available for 70mm Gate Rollers?

The 70mm wheels in this set are available in two primary groove profiles.

V-groove is designed for secure tracking on angle iron rails and V-track systems. The V-groove design provides low friction and quiet operation, making it ideal for security gates and automated gates. The twin-wheel design ensures smooth rolling movement and stability for your gate.

U-groove is designed for U-groove tracks, ensuring a secure fit and reliable performance. The U-groove sliding gate wheel rollers provide exceptional stability and durability. The double bearings allow for effortless movement, reducing friction and ensuring a quiet and smooth sliding motion.

What Guide Wheel Options Are Included?

The “2-in-1” designation is completed by the inclusion of guide wheels.

Guide wheels are typically 40mm x 40mm or 30mm x 40mm in size. Their function is to maintain gate alignment and prevent lateral movement.

The roller structure effectively reduces friction when the gate moves, making opening and closing easier and smoother. The sliding door guide roller can be installed on the support or on the rear column wall to achieve smooth operation and prevent the door from tilting off the track.

How Do You Install a 70mm Double Gate Roller Set?

Installation options vary by specific set.

For the U-groove internal bracket model:
First, prepare the gate and track. Ensure the sliding gate is installed and the track is level and secure.

Second, measure the cradle. Measure the sliding gate wheel cradle to ensure enough space to attach the wheel to the steel frame. Drill four holes using an appropriate drill bit.

Third, clean and protect. Clean up the rectangular hole with a file to ensure smooth edges, then spray the area with galvanised paint for protection.

Fourth, place the wheel. Place the sliding gate wheel into the cut-out and check that it can rotate freely.

Finally, secure the wheel. When screwing in the tek screws, make sure the wheel is aligned with the edge of the steel.

For the complete 2-in-1 set:
The wheels and rollers can be bolted onto the gate frame using the included hardware. The simple design allows easy placement on all sliding gate tracks with minimal maintenance required.

Where Should You Use a 70mm Double Gate Roller Set?

The set is suitable for numerous applications.

For residential sliding gates, use for driveway gates and garden entrances. For automated gates, it is compatible with motor gate systems.

For commercial security gates, use for factory and warehouse perimeter entrances. For industrial applications, use for rolling doors, machine rails, wire rope rail devices, and container racks.

For agricultural gates, use for farm and ranch gates that must operate over uneven terrain.

What Is the Load Capacity of 70mm Double Gate Rollers?

Load capacity varies by configuration.

Single U-groove wheels support 220kg per wheel. They are best for residential gates and light duty applications. The 2-in-1 complete set supports up to 800kg total gate load. It is best for residential and light industrial use.

For a standard residential gate, the 2-in-1 complete set provides substantial capacity for most driveway and garden gates.

What Are the Advantages of Double Bearings in Gate Rollers?

Double bearing gate rollers offer significant performance benefits.

Reduced friction means two precision bearings distribute the load more evenly, reducing rolling resistance. Enhanced stability means the double bearings allow for effortless movement, reducing friction and ensuring a quiet and smooth sliding motion.

Better weight distribution means the dual bearing design provides greater flexibility, reduces vibration, and ensures smooth operation. Extended service life means with bearings sharing the load, individual components experience less stress, resulting in longer operational life.

What Are the Material Options for 70mm Gate Rollers?

Zinc-plated steel is corrosion-resistant, has a gold finish, and is durable. It is best for outdoor gates and weather-exposed installations.

Carbon steel has high strength and heavy-duty construction. It is best for industrial gates and heavy-load applications.

Galvanised mild steel is rust-proof with one-piece molding. It is best for general residential and commercial use.

Nylon is wear-resistant, corrosion-resistant, and offers quiet operation. It is best for guide rollers and noise-sensitive areas.
