Heavy-Duty Drawer Slides
100lb–250lb full-extension ball bearing slides with optional locking
Built for Demanding Loads
BWD heavy-duty drawer slides are engineered for sustained loads from 100 lb (45 kg) to 500 lb (227 kg) per pair, targeting industrial cabinets, truck/RV storage, warehouse bin systems, and CNC machine drawers. Every slide uses cold-rolled carbon steel rails (SPCC/Q235) with hardened ball bearing raceways rated for 50,000+ full-extension cycles under maximum load, verified via in-house BHMA A156.9 cycle testing.
Key features: full-extension or over-travel (105-115%); optional dual lock-in/lock-out; zinc plating (8+ micron) or e-coat (salt spray 72+ h per ASTM B117). Rail thickness 1.0-1.5 mm by load class; lengths 250-900 mm with custom lengths available.
Selection: match load rating to drawer weight with 25%+ headroom. Side-mount for widest compatibility; bottom-mount when interior width is critical. For vibration environments (vehicles, machinery), always specify locking variants.
