Full-extension linear slide SDB series

telescopicdrawerheavy-duty

OverviewRear-mount drawer slides are telescoping linear rail assemblies supported from a rear mounting surface and designed for full-extension movement. The SDB Series uses two hardened steel SDP rails mounted back-to-back to form a rigid telescoping configuration that lets the internal slider extend beyond the nominal rail length, providing long reach from a compact mounting footprint. This rear-mount arrangement is ideal where side mounting is impractical, access is confined, or a cantilevered load must remain stable through the full stroke. SDB slides are intended for heavy-duty and industrial drawer applications, delivering guided motion, load support, and extension rigidity.

Features

• Extended telescoping motion: stroke exceeds individual rail length
• Design flexibility: available in single- and double-direction stroke configurations
• Maximum stroke: up to 2,026 mm
• Rail lengths available: 130 mm to 1,970 mm
• Load capacity: up to 3,092 N
• Back-to-back rail configuration: improved rigidity during extension
• Construction: hardened steel SDP rails; typical variants include hardened, zinc-plated steel with precision ball guidance for corrosion resistance and smooth motion

Frequently Asked Questions

• What is a back mount or rear mount drawer slide? A rear-mount drawer slide is a linear rail assembly supported from the rear mounting surface and intended to carry cantilevered loads where the moving element extends outward without side support. It is used when side mounting is not practical or when extended reach is required from a compact base.
• When should a back mount drawer slide be used instead of a side mount? Use a rear-mount slide when side access is limited, when the application requires the load to extend outward from a fixed rear support, or for cantilevered and deep assemblies that need long reach from a compact footprint.
