CB4500 Heavy-Duty Cylinder-Bed Leather Sewing Machine
The HighTex CB4500 is a heavy-duty cylinder-bed sewing machine designed for professional leatherwork, saddlery, harness making, upholstery, and other demanding applications involving thick and difficult-to-sew materials.
Its compound-feed mechanism combines the feed dog, walking foot, and needle feed to provide consistent material feeding, while the large-capacity shuttle hook and heavy-thread capability make it suitable for demanding leather sewing applications.
With a maximum sewing thickness of up to 7/8 inch (22 mm) and a low-speed, high-torque servo motor, the CB4500 provides the power and precise speed control required for professional leatherwork.
Key Features
- Compound-feed mechanism — Feed dog, walking foot, and needle feed work together to provide consistent feeding of difficult materials.
- Extra-large shuttle hook and bobbin — Provides increased bobbin capacity and supports heavy thread sizes while reducing bobbin changes.
- High presser-foot lift — Up to 1 1/16 inches (25 mm), allowing clearance for thick and bulky materials.
- Large 12-inch flywheel — Provides additional torque for sewing hard and rigid leather.
- Precise reverse stitching — Designed to return reverse stitches into the same holes for consistent seams.
- Adjustable pedestal stand — Provides additional working clearance and free-arm access around the cylinder bed.

- High-torque servo motor — 750W / 110V low-speed servo motor provides controlled and precise sewing speed.
Precision Speed Control
The CB4500’s low-speed, high-torque servo motor allows operators to control sewing speed precisely, making it easier to sew thick leather and detailed work stitch by stitch.
A soft-start function helps provide smoother operation when beginning a seam.
Optional controls may include:
- Jog Dial for precise needle-bar positioning
- Speed Controller for adjustable sewing speed
- Half-Stitch Function for fine stitch positioning
- Needle Positioner for improved needle positioning
Optional controls and accessories may vary by configuration.
