LDF Series Large Diameter Gages

LDF series production gages utilize fixed frames which are more rigid, lighter and more compact than LDA series adjustable gages. LDF gages are normally used for tight tolerances and built to order based on application requirements

Hump Frame

Description

This design can be used on the LDF, LDDF, or the LDLTF to increase the rigidity of the vertical gaging shafts by extending the support castings up to 5.5" deeper. It is generally recommended to use this type of frame design if the gaging depth exceeds 6". Add "-HF" to the part # of the basic gage to select this option.

Donut Frame

Description

This design can be used on LDF, LDDF, or LDLTF. The Donut Frame design permits the gage to completely encircle a large obstruction such as the part’s hub, case, clamp, or fixture setup. Special size Donut Frames are also available.

Extended End Block Frame

Description

Due to part configuration, it is sometimes necessary for the gage frame to rest internally or externally to the check dimension. Holding fixtures used during the machining operations can introduce further restrictions that may require gages to rest on fixture pads located outside or inside the part.

Bridge Frame

Description

This design permits the gage frame to bridge over short center obstructions such as posts, clamps, or raised contours. These castings extend and support the gaging extension shafts in order to gain measuring rigidity. This raises the frame 2.75". Add "-BF" to the part # of the basic gage for this option.

"C" Frame

Description

LDC series "C" frame gages are used for applications where the gage cannot be placed directly over the part. The frame is intended to partially encircle the part and is "side loaded" during use. Cam style (LDF), lever style (LDLT), or direct read type (LDD) transfer mechanisms can be used on this frame.
