Fire-retardant leather bellows protecting machine guideways and spindles from chips, sparks, and coolant — manufactured to drawing from a single piece.
Every bellow is manufactured to order from your dimensions, drawing, or physical sample. Minimum order: 1 piece.
Fire reaction class B1, resistant to sparks up to +300°C. Leather thickness 1.2 / 1.5 / 2.0 mm. The standard choice for welding and CNC environments.
Stainless steel 304 or 316 leaf inserts provide axial rigidity and longer travel life. Suitable for high-cycle CNC machining centres and industrial presses.
Maximum travel up to 3000 mm with a 1:5 compression ratio. Available with 2–12 leaves to match the required stroke and collapsed height.
Conical or cylindrical profile, diameter range 30–500 mm. Used on lathe spindles, grinding machines, and rotary axes. Conical form for tapered slides.
Width 50–800 mm, height 30–400 mm, double or triple stitched seams. Standard solution for milling machine tables and linear guideways.
Any shape or size manufactured to ±1 mm tolerance from genuine leather or synthetic fire-retardant material. Minimum order: 1 piece.

Every bellow is made to measure. Here is how it works from enquiry to delivery.
Share your drawing, sketch, or physical sample with overall, collapsed, and expanded dimensions.
Our engineers review the application and create a cutting pattern optimised for fit and service life.
Leather cut, folded, and stitched by hand — each seam double or triple stitched for maximum durability.
Dimensional check against drawing before dispatch. Shipped with a certificate of conformance.
Leather bellows protecting critical machine components across many sectors.
Send us the dimensions or the old bellow — we will manufacture an exact replacement or an improved version.
