The H in 1508H means very heavy duty, with longer stroke 190R Needles which allows for thicker fabrics and higher foot lift, a bigger hole in needle plate for thicker threads, and bigger teeth on the feed dogs which allow better feeding on thicker fabrics, etc compared to 1508N and 1541N that take shorter stroke 135×17 needles.

Note: Assembled Table , Stand and Motor. The very best heavy duty compound feed, walking foot and needle feed machine for applications including auto upholstery.N Stands for the Color: White
H Stands for Extra Heavy Duty 10-15% heavier duty than the Standard NS Version, with a longer needle and higher stroke.

• Single Needle
• Needle Feed And Walking Foot
• 2500 Stitches Per Minute
• New Rectangular Feed Prevents Gathering
• Includes Table, Stand, And Motor
• Handles Heavyweight Materials
• Industrial Sewing MachineThe Juki LU 1508 replaces the very successful Juki 562/563 model, which was sold for over 20 years and is still is use with many manufactures.This new model has many new features which Juki has researched & tested thought-out the heavy-weight fabric industry.It is a general purpose needle feed, walking foot machine for use on medium-heavy weight materials and is suited to sewing, for example, car seats, carpets, general upholstery and leather articles etc.FEATURES:
• New mechanism with a rectangular feeding motion promises consistent feed of materials of all thickness without the risk of stitch gathering
• Reduced lift of feed dog helps prevent the material from flopping and reduces operating noise and vibration
• With adoption of a new rectangular feed mechanism, an alternating vertical movement mechanism and a unison feed mechanism helps feed heavyweight materials powerfully and smoothly
• Well tensed seams are consistently produced without pitch errors
• With its maximum stitch length of 9 mm, the machine can be applied to a broader range of uses
• Stitch length can be easily selected by the stitch dial
• Many improved features offer enhanced operability such as an easy-to-observe area around the needle, placement of bobbin winder on the front face, and a large hand-wheel
• Knee-lifter mechanism built-in to bed reduces pressure required to operate the knee-lifter
• Full-open-type top design makes it possible to fully open the top of the machine arm and helps make adjustment easy without tilting the machine head
• Alternating vertical movement mechanism prevents irregular stitches
• High 16 mm presser foot lift enables easy material handling
• Since machine incorporates a vertical-axis double-capacity hook, the frequency of bobbin thread replacement is reduced, further increasing efficiency
• If thread gets caught in the hook, the safety device is automatically engaged, preventing possible hook damage
• Pressing the reset button will immediately return the machine back to the normal state
