Ball Transfer Unit KSM SP series

Core Advantages of SP Series

• SP Heavy-Duty Solid Machined Body One-piece thick housing, forged & precision turned, no deformation under continuous heavy impact loads, far stronger than thin stamped light-duty ball transfers.

• Two Surface Options: Stainless Steel / Chrome-Plated Carbon Steel Carbon steel shell with hard chrome plating achieves higher surface hardness, scratch resistance and gloss than traditional zinc plating; stainless steel variant meets cleanroom, food and marine anti-corrosion standards.

• 360° Omnidirectional Smooth Movement Multi-layer tiny support ball structure minimizes friction, heavy goods slide effortlessly in any horizontal direction without jamming or stuck balls.

• Simple Recessed Press-In Installation SP drop-in design only requires matching drilled holes on workbench/conveyor, press in directly without extra fasteners, fast assembly for mass production lines.

• Long Service Life & Low Maintenance Sealed inner structure blocks dust, metal chips and coolant contamination; pre-filled industrial lubricant extends re-greasing cycles.

• Full Size SP Series Coverage Complete size range from mini SP12 to ultra-heavy SP90, customizable ball materials (nylon ball optional for scratch-sensitive workpieces).

Wide Industrial Applications for SP Series Ball Transfer Units

• Warehouse & Logistics Conveying Equipment Heavy-duty pallet flow racks, cargo sorting tables, loading/unloading platforms, air cargo transfer stations (SP series is mainstream air freight ball transfer)

• Automotive & Heavy Machinery Assembly Lines Car chassis assembly stations, engine positioning worktables, heavy vehicle component sliding platforms, mold quick-change carts
