YDTech® MANUFACTURER of metric grooved taper pins studs(A,B,C types); supplier of dowel^cotter grooved pins with split(Y15,Y12, stainless steel) in china.
What's grooved(dowel) pins?
grooved pins are press-fit fasteners that combine superior holding power, unparalleled vibration and shock resistance, and easy installation. Each solid cylindrical pin features three longitudinal grooves that have been pressed in to expand the pin’s original diameter in a precisely controlled way. This creates a strong spring mechanism.
how grooved pins work?
When pressed into a hole the size of the grooved pins original diameter, the hole compresses the expanded pin and creates a forceful hold. This unique locking action is cre.
as a professional grooved pins, needle rollers, tapered rollers manufacturer, exporter, supplier and factory in china.We focus stable high quality and professional service as well as reasonable price. supported by our very strong team. we are the right company to supply our customers with very stable high quality products, cylindrical roller, needle roller, tapered roller and professional service.
advantages of grooved pins
withstand severe shock/vibration, even with axial displacement. Solid construction stronger than spring pins. Different groove types for a wide range of applications, require only a straight drilled or molded hole,reduce assembly steps. driven with hammer, air cylinder or hydraulic press. easy installation and quick assembly, removable and reusable.
