Special Features

special-features-1.png

One piece construction is superior to our competitor's 2 piece.

special-features-2.png

Our design uses a splined pinion shaft which is much stronger and more rigid than the keyed shaft.

special-features-3.png

Our standard spring type micrometer adjusting nut provides quick and easy movement for setting spindle depth.

special-features-4.png

Gaskets are used to prevent grease and oil leakage.

special-features-5.png

One pieces quill housing ensures precise alignment, eliminates vibration, and prevents premature bearing failure.

special-features-6.png

Dynamically balanced pulley with special bronze key attached with 2 screws prevents premature breakage.

special-features-7.png

Our special power down feed parts are so strong, they can be used over 3,000 RPM spindle speeds. Our 1 piece cluster gear is superior to the much used 3 piece design.

special-features-8.png

The splined shaft is much stronger and provides greater safety than the keyed shaft.
