The 97 End cover represents one of the most frequently encountered mechanical components across diverse industrial applications and manufacturing sectors, functioning as a critical external structural element integrated into bearing seat assemblies. Within the broader context of rotating machinery design, the end cap serves multiple essential engineering functions that directly impact both operational reliability and component longevity.

The end cover is simple in structure and common in shape, and belongs to a general disk cover part. The main processing surface has the end cover left and right end faces, square end faces, requiring the end runout relative to the axis to meet 0.03mm, followed by the φ25 holes and φ10 holes in the 25 holes of the processing face is flat, can prevent the cobalt head in the processing process to ensure the processing accuracy of the hole; In addition, although the processing surface of the 10 holes is on the circumference, the processing technology requirements can be guaranteed through the special fixture and drill sleeve. In addition to the main machining surface of the part, the rest of the surface processing accuracy is low, do not need high-precision machine tool processing, through milling, drilling machine roughing can meet the processing requirements. It can be seen that the processing property of this part is good.
