Model-specific review

Interpret this model's dimensions

The slash names the cone/cup pair, not two spelling alternatives. Source-published metric values retain their inch-design reference context; confirm both component identifiers and do not round the envelope into a nearby metric model.

These values describe the cited engineering reference. They do not verify LTO-specific load ratings, speed limits, material, precision, clearance, seals, application suitability or interchangeability. Provide the complete designation, quantity, drawing and operating conditions for quotation review.
