Mitutoyo 21DZA235 | Guide Assembly | Series 511
Part No. 21DZA235 | Type Guide Assembly | Fits Series 511 Bore Gauges | Quantity 1 Piece
Product Overview
The Mitutoyo 21DZA235 is a guide assembly spare part for Series 511 bore gauges. It is intended as a replacement component when the original guide assembly is worn, damaged or missing and helps maintain the mechanical operation of the bore gauge.
A dial bore gauge depends on precise movement between its contact mechanism and indicator. Wear, damage or incorrect replacement hardware can introduce unwanted movement or affect the way components seat within the measuring head. Using the correct replacement part helps restore the gauge to its intended mechanical configuration.
The 21DZA235 is identified by its exact Mitutoyo part number, making part-number matching the preferred way to order. Mitutoyo does not publish detailed dimensional specifications for this individual spare part, so dimensions, thread details and other physical measurements should not be assumed from the part number alone.
The part is listed for Series 511 bore gauges. If you are unsure whether 21DZA235 matches your specific gauge, provide the gauge order number, such as 511-713-20, or send a clear photograph of the existing component. General Tech Services can help confirm compatibility before you order.
If other components show wear during inspection or calibration, replacement parts and bore-gauge service or calibration can also be discussed.
