Product Description (Listing-Ready)

The SKF SIKB12F/VZ019 is a female-thread rod end incorporating a spherical plain bearing (no rolling elements). It is commonly used on hydraulic or pneumatic cylinders and linkage assemblies where misalignment capability is required, while supporting radial loads in tension or compression.

This maintenance-free version features a steel-on-PTFE sliding contact. During run-in, PTFE transfers to the opposing surface and fills minor surface irregularities, helping create a smooth, low-friction contact surface for reliable operation.
