Full Extension Ball Bearing Drawer Slides 550mm Soft Close H53 80kg / pc

Usage

This full-extension soft-close ball bearing slide, 550mm in length and 53mm in height, is designed for heavy-duty drawers requiring smooth, controlled closing. It is suitable for furniture manufacturing, industrial applications, and machinery assembly.

Advantages

• Soft-close mechanism ensures silent and gentle drawer closure, preventing slamming and reducing noise[6][7].
• Impressive load capacity of up to 80kg per pair supports heavy contents without compromising stability[2].
• Full-extension design provides complete access to the entire drawer space for convenience[3][9].
• Durable steel construction with galvanized finish resists wear and corrosion over extended use[2][4].
• If installed flat instead of vertically mounted on the side, load capacity may be significantly reduced (to approximately 25%)[2].

Specifications

• Material: Galvanized steel with hardened steel ball bearings for quiet operation and longevity[2][4].
• Smooth motion system certified for high cycle durability; typically rated for over 100,000 open/close cycles at specified load capacities[1][4].
• Total slide length: 550mm; installation height: approximately H53 mm; maximum dynamic weight capacity: up to 80kg per pair when mounted vertically[1][2].
• Differentiators include a reliable soft-close damper system and tool-free disconnect feature for easy maintenance or cleaning.

How it works

The runner uses a ball bearing cage system combined with an integrated soft-close damper. When closing the drawer, the damping mechanism automatically slows down movement near closure to ensure a quiet finish while protecting both contents and cabinetry from impact damage[6][7][9].
