Compared to the m7 type, the p7 type has greater inner diameter shrinkage, so please pay attention during hole machining.The inner diameter tolerance of the bushing is highly precise. If a vernier caliper is used for measurement, the result may be smaller than the actual value. It is recommended to use high-precision measuring instruments (such as an inside micrometer or plug gauge) for inspection.Some specifications and models may be incomplete. Thank you for your understanding!Feature 2: The economy bushings offer a higher cost-performance ratio, and in-stock models can be shipped the same day.
Feature 3: Equipped with a reference line, which can be used to align the horizontal position during press-fit installation to ensure smooth installation of the bushing.
Feature 4: Material: Bearing steel (SUJ2).
Feature 5: The inner diameter tolerance is F7, which increases the clearance with the locating pin, making assembly and fitting quicker.
