Self-Locking Ball Bearing Slides

HA5333 Heavy-Duty Self-Locking Ball Bearing Slides

The HA5333 is a heavy-duty, 3-section self-locking ball bearing drawer slide designed for robust industrial applications. With a load capacity of 115kg (250 lbs) at 450mm (18"), it features a durable 2.0mm thick cold-rolled steel construction with a blue zinc-plated finish for corrosion resistance. Available in lengths from 16" to 26" (400mm-650mm), this non-separable slide ensures smooth, full-extension operation with minimal friction, thanks to high-quality steel balls. Its spring-loaded lock mechanism at the slide's front secures drawers in both closed and extended positions, ideal for industrial drawers, vehicle toolboxes, and large trays. Engineered for stability and longevity, the HA5333 undergoes rigorous testing, including 100,000 open-close cycles, making it perfect for demanding environments like server racks, medical equipment, and heavy storage systems.

Key Innovations:
Positive Auto-Lock - Front-mounted spring steel tab ensures automatic engagement when closed and secure retention when extended
Industrial Durability - 2.0mm triple-wall construction with blue zinc plating resists corrosion (500hr salt spray tested)
Vibration-Proof - Pre-loaded ball bearings maintain alignment in mobile applications

A fresh locking system. To open or close the drawer, you must press the blue button. Whether fully extended or closed, it will lock.

Constructed with 2.0 mm thickness cold-rolled steel. By using 5% salt spray for 48 HRS
