Product DetailProduct Overview
The bushing for locating pin is a mechanical positioning part that is used in conjunction with a positioning pin to achieve a guiding effect, in whch the round flanged type can be fixed by bolt, is easy to install, has high fixing strength (falloff prevention), and can effectively prevent the rapid wear of the workpiece.

Specifications Overview
■Material Specification Table
If there are requirements for rust prevention, give priority to the products with surface treatment of electroless nickel plating or products made of austenitic stainless steel.
Since the wall thickness of the countersunk hole is only about 1.5mm and the product is hard, make sure that the flange edge fits perfectly with the mounting surface before locking the bolt. Otherwise there is a risk of rupture of the countersunk hole.
The I.D. tolerance of bushing is high. If a vernier caliper is used for detection, the measurement result will be too small. It is recommended to use a high-precision measuring tool (internal micrometer or plug gauge, etc.) for detection.

Example introduction: Application of flanged bushings for locating pins in fixtures
Function description and precautions:
The fixture plate has positioning accuracy requirements during operation, and is designed to use a bushing to mate with the locating pin to ensure positioning accuracy. Since the fixture plate is susceptible to impact during operation, the bushing is bolted and countersunk in areas where space is confined.
Advantages of flanged fixture bushings:
①The bushing hardness is slightly lower than the positioning pin, which effectively protects the positioning pin from rapid wear and ensures the positioning accuracy.
②The bushing is easy to replace when it wears out, effectively protecting the bottom plate or workpiece from damage.
③Bolts can be used for fixing to ensure that the bushing will not fall off or rotate under the actual operating condition.
