The sinoboltco SNBP000003 series represents the pinnacle of compact, reliable mechanical positioning hardware. Designed as a double-ended press-fit component, these knurled ball plungers are engineered for precise detent, indexing, locking, and locating applications where space is limited but reliability cannot be compromised. The unique integration of a brass body with dual stainless steel balls provides smooth mechanical cycling and exceptional longevity in automated systems, jigs, fixtures, and custom hardware assemblies.
Product Advantages
Dual-Material Performance: The combination of a heavy-duty brass shell and dual stainless steel components yields excellent natural lubricity, minimum wear, and zero rusting.
True Press-Fit Knurling: The raised straight-knurl band at the center of the SNBP000003 ensures a tight, friction-locked interference fit inside smooth bored holes, eliminating the need for costly tapping operations.
Double-Sided Functionality: The dual-ball layout allows for symmetrical positioning and balanced mechanical force distributions across your assemblies.
Strict Load Calibration: From the lightweight 1.3N option up to the heavy-duty 15N option, our internal springs deliver highly predictable mechanical resistance through millions of duty cycles.
