60kg Heavy Load Over-Travel Ball Bearing Slide Rail

HA3504 60kg Heavy Load Over Travel Ball Bearing Slide Rail

In many industrial and equipment applications, standard drawer slides may not provide enough travel distance for accessing items stored in deeper compartments. When the drawer or platform needs to move further beyond the cabinet edge, an over travel slide can offer a more flexible solution. This type of slide is designed to improve accessibility while making better use of limited installation space.

The HA3504 is developed for projects that require more flexibility in drawer movement and better utilization of internal space. Compared with conventional slide solutions, its special over travel design helps create additional access distance, allowing users to reach items or components that are positioned deeper inside the cabinet or equipment. The double layer structure provides a balanced combination of compact installation and extended travel capability. It is often selected for industrial storage units, maintenance equipment, tool organization systems, and other applications where convenient access and smooth operation are important factors.

Long extension capability improves accessibility in deep cabinets and equipment systems.

Constructed with 1.50 mm thick cold rolled steel and tested by 5% salt spray for 48 hours.

The ball bearing action can create a quiet environment at work.

Nylon buffer can reduce the direct contact between the outer and the inner channel.

APPLICATIONS

Laboratory Equipment Cabinets
Applied in laboratory storage units to provide stable movement and help users access equipment and materials stored at the back of the drawer.

 

Electrical Control Cabinets
Used in electrical cabinets and control system enclosures to allow internal modules or trays to extend outward for easier maintenance. 

Commercial Display Cabinets
Applied in display and presentation cabinets to create smooth pull-out functions and improve access to displayed products.

 

 

Industrial Workstations
Used in production workstations and assembly areas to support pull-out platforms and improve workspace flexibility. 

Q1: What makes this slide different from a standard full extension slide?
A: Unlike standard slides that stop at the normal full extension position, this model uses a double stack structure to achieve additional travel distance. It allows the drawer or platform to move further outward, improving access to deeper storage areas.

Q3: Does the slide require additional support when used at longer extension lengths?
A: For longer extension applications, proper installation and a suitable drawer structure are important. The supporting frame should be designed according to the expected load and working conditions.
