Industrial Double Flange Knurled Bushing for Press

Qimao Metal Manufacturer provides high-quality Industrial Double Flange Knurled Bushing for Press in China. The double flanges prevent axial walking by contacting the housing faces on both sides. A plain bushing has no such stops. Once you press this bushing, the flanges hold depth position permanently. The knurling holds rotational position permanently. You still get a smooth inner bore for shaft or pin movement. But you no longer worry about the bushing backing out or spinning inside the machine. It is a small change in design that makes a large difference in long term reliability.

Our advantage

We produce every Industrial Double Flange Knurled Bushing cold former mold, so flange thickness stays consistent across whole production runs. Our knurling tooling uses form rolls that create full depth teeth without tearing or smearing the material surface. We stock 1215 steel, 360 brass, and 303 stainless blanks ready for same day machining to your length and bore size. Each bushing gets a quick bore check with an air plug gauge before packing. You can order small trial lots of ten pieces without paying setup fees charged by larger bearing houses. We also offer press fit calculators on our website where you enter housing material and bore size then we recommend exact outer diameter oversize. For urgent breakdown repairs we often ship within 24 hours for standard industrial sizes. Random samples get pulled for torque testing to verify knurl grip strength before labeling.

Product Parameter (Specification)

Product Feature

· Double Flange Stopping Power: Both flanges work together to limit axial movement in both directions, so the Industrial Double Flange Knurled Bushing for Press stays exactly where you pressed it without shifting under reverse loads.

· Knurled Locking Grip: The outer knurl pattern digs into the softer housing material during press fit assembly. This mechanical lock stops spinning even when the mating shaft cycles on and off repeatedly.

· Self Centering During Install: Because flanges sit on both sides of the bushing body, the part aligns itself straight as you press it into the bore. Crooked installations happen less often.

· Smooth Inner Bore: The inside diameter is reamed after knurling so it stays round and consistent. Pivots and sliding shafts move freely without scratching or binding up over time.

· Material Choices: Select brass for corrosion resistance, steel for heavy loads, or stainless steel for wet or wash down environments. Each version holds the knurl pattern differently.

Application

· Press Tooling & Die Sets: Industrial Double Flange Knurled Bushing for Press used as guide bushings in stamping dies where the upper shoe moves up and down repeatedly. The knurling stops rotation while double flanges hold depth setting.

· Hydraulic Cylinder Pivots: Fits into clevis mounts or cylinder rod ends where a steel pin rotates through the bushing. The lock keeps the bushing from walking out during articulation.

· Agricultural Linkage Pins: Works on tractor three point hitch arms or implement pivots where dust and vibration would loosen plain slip fit bushings over time.

· Packaging Machinery: Installed into oscillating arms on carton folders or seal jaws. Double flanges keep the bushing centered in thin wall brackets.

· Automotive Jigs & Fixtures: Used in weld fixtures or assembly line stops where locating pins need a wear resistant sleeve that will not shift position after thousands of cycles.

· Conveyor Roller Ends: Pressed into the ends of gravity conveyor rollers where the axle runs through. Knurling stops the bushing from spinning inside the roller tube.

Product Details

Shop floors often deal with two problems on press fit bushings. First, the bushing spins inside the housing after a few cycles. Second, the bushing walks out axially when loads reverse direction. This Industrial Double Flange Knurled Bushing for Press solves both at the same time. The knurling digs into the bore wall during installation and creates a interference lock that stops rotation permanently. The double flanges work like built in stops so the part cannot shift forward or backward under vibration. You do not need set screws, Loctite, or snap rings to hold it in place. Once pressed, it stays exactly where you set it. The inner bore stays smooth for pin movement while the outside fights movement. Machine builders like this design because it cuts assembly steps and eliminates future callbacks for loose bushings. It simply works harder than plain sleeve designs.
