It’s a Direct Bolt-on Replacement for Bridgeport 2J head (vari-speed) or J head (step-pulley) or the heads on other Bridgeport-type knee mills.

Yaskawa Variable Frequency Drive
EVS drive allows stepless spindle speed change at a turn of a knob. Insist on the best. We use Yaskawa V1000 frequency drive. 

High Precision You Can Count On
Our milling spindles are hardened, precision ground and chromed.
The spindle is supported by high precision preloaded bearings that can also handle high thrust load.
Spindle runout is within 0.00015”.

Durable Design Features 3-Bearing Support
Within the milling motor there are two support bearings. With our millign head, there's an ADDITIONAL bearing to support the drive pulley at the end of the motor shaft. This is an important feature to ensure smooth power transmission and motor durability.

Save Time and Money
Avoid hunting for spare parts. Avoid the downtime and uncertainty of rebuilds.
A direct replacement is a straight forward and economical solution.

Satisfaction Guaranteed
We thrive on repeat business. Some of our customers buy new milling heads from us to replace the heads on their aging Bridgeport milling machines year after year.
That’s the best testament to the quality of our milling heads.
