Dynapro runner set, Grass Dynapro, full extension, load bearing capacity up to 50 kg, steel, surface mounted, snap-in coupling

  • Information
  • Runner type

    The type of runner is determined by the design of the running elements, independently of the mounting method.


    Plastic guide railsact as gliding surfaces that support the weight of drawers and their contents.


    Roller guided drawer runnersThe running elements are rollers. The type of roller varies from friction bearing mounted polyamide rollers to ball bearing mounted polyamide rollers, ball bearing mounted polyamide-coated steel rollers and soft rollers for silent moving.


    Ball guided drawer runnersSteel or plastic balls in ball cages are used as the running elements.

    Groove mounted runners, are a subgroup of the ball bearing runners and are characterised by following features:

    • The runners are recessed into a groove that is milled into the drawer side or side panel.
    • Small gap between drawer and side panel
    • Installation with threaded screw inside the drawer
    • Can be removed by loosening the screws

    Roller bearing guided concealed dynamic runnersRollers are running elements in running gears.


    Mounting option

    Internal drawer

    The drawer front panel is flush or set back from the cabinet side panel.


    Load bearing capacity

    The load bearing capacity values for Accuride runners apply to a rail length of 450 mm and an extension width of 450 mm. Unless otherwise specified, the load bearing capacity of longer rails is about 20 % less.


    Something that all of the information has in common is the fact that the values for dynamic loading apply, and only if all mounting holes are screw-connected using suitable fastening material.


    The load bearing capacity of ball bearing runners that are suitable for side and base mounting is reduced to about 25% if the ball bearing runners are installed horizontally.


    We recommend trial mounting to determine if lowering lies within an acceptable range.
