A drawer slide is a mechanism that allows for telescopic motion in one axis and are commonly found in a wide range of household and industrial applications. There are six types of drawer slides, however the technology used is really only split into two types, the others refer to the installation location.  Roller slides and Ball-bearing slides. This blog will aim to help you distinguish between these types of drawer slides. To learn more about the basics of drawer slides, check out our Drawer Slides 101 blog.

Roller Slides

Roller slides or rolling drawers consists of two components, the cabinet member and the drawer member, each having their own roller, usually made of plastic. As their names suggest, cabinet member mounts to a stable or grounded component, i.e. the cabinet, and the drawer member attaches to the moving component, i.e. the drawer. Each roller will fit into the groove found on the other member and will be at opposite ends of the mechanism when fully retracted with the cabinet member’s roller being at the front. As the mechanism is extended, the cabinet member’s roller allows the drawer member to move outwards and the roller of the drawer member follows in the grove of the cabinet member. When fully extended, the two rollers will meet. This two-roller design gives the mechanism horizontal stability and allows for level extension.

You’ll typically see roller drawers slides used in household applications like desk drawers where you expect fairly lightweight loads and a horizontal configuration using bottom drawer slides. Due to their design, it is not recommended to use roller slides in any other configuration than horizontal. They also can only be mounted to the side of a drawer due to their design.

Ball-Bearing Slides with soft close

Ball-bearing slides make use of ball bearings instead of rollers to allow for the telescopic motion. They consists of three components; the cabinet member, intermediate member, and the drawer member. Like with the roller slides, cabinet member mounts to a stable or grounded component, i.e. the cabinet, and the drawer member attaches to the moving component, i.e. the drawer. The intermediate member interfaces with two sets of ball bearings; the first set interfaces with the grooves of the cabinet member and the second set interfaces with the grooves of the drawer member. As the mechanism extends, the first component to move is the drawer member, which slides over the ball bearings between itself and the intermediate member. Once the drawer member reaches the end of the ball bearings, the intermediate member will begin to slide along the ball bearings between itself and the cabinet member until fully extended. Like the two-roller design, the ball bearings within each groove of the mechanism gives it horizontal stability and allows for level extension.

The Soft close feature of a drawer slide is typically available in two different styles, one fsar more expensive than the other. Once method is where a rubber coating is applied to a particular part of the slide rail component along with an indentation on the metal to create a soft closing feature on both the open and closed actions.  This method works very well for most applications where alot of weight is used.  The second method is where a damping piston type device is actually place in the rail system to offer what we call a parachute landing style closing (only on the closing), This works fine for kitchen cabinets where the weight is not that high, but not suitable for heavy work loads.

You will see ball-bearing slides used in a wide range of applications from household applications, like dresser drawers, to industrial machinery. The use of ball-bearings in the design of these drawer slides provide greater durability and can carry larger loads compared to the plastic rollers of roller slides. As the ball-bearings of these drawer slides are fitted within the grooves of each member, they are capable of being used in horizontal configurations, vertical configurations, and at various angles. Some ball-bearing slides can be mounted to either the sides or bottom of the drawer, but you’ll need to check the manufacture’s specifications to ensure you can do so and how bottom mounting effect other specifications like load rating. You can also find heavy duty versions of ball-bearing slides that are design for harsher and heavier applications.

Locking Drawer slides (Lock in and Lock out)

Locking Drawer slides (Lock in and Lock out) are needed for applications where the drawers are typically in a mobile application and thus you cannot have the drawere opening and closing when the vehicle is in motion.  The FIRGELLI style of locking drawer slides have a lever tthat sticks out the front and that has a blue rubber handle molded onto it to give it a nice soft feel. The process is simple, you simply press the lever down (one on each slide) and that unlocks the slide so you can open the drawer. Once fully extended the slides also lock into their full open position and cannot be closed until you press the lever again to close them.  These locking style drawer slides are available off the shelf in different extensions and can hold 500-lbs weight a pair.
