HIGH-SPEED KNOTTED-WIRE CUP BRUSH FOR HEAVY DUTY CLEANING
Osborn (Brooklyn Heights, OH), a leading global supplier of industrial brushes, introduces its redesigned, high-speed, knotted-wire cup brush. The improved brush features a taller inner cup that forces the brush to be used on the filament tips, rather than bending. Featuring the highest quality AB wire in the industry, threaded-nut connection and aggressive knot style, the redesigned cup brush offers premium performance.

“This new design on Osborn’s popular cup brush forces the brush to be used on the tips of the knotted filaments, preventing bending and providing improved performance,” explains Mark Johnson, the vice president of sales and marketing at Osborn. “In-house testing in our brush lab showed excellent results and we’re happy to provide a stronger product to users.” These knotted-wire cup brushes are rugged and efficient tools for heavy-duty cleaning of metal surfaces. They are specially designed for use on portable tools and filled with steel-wire filament for rigorous applications.

The company also announces its new 114-knot cutback brush. Used for angled removal of three or more layers of coating from pipe ends, the new brushes incorporate the heavy-duty features and quality expected from Osborn, which worked with leading machine manufacturers to develop the 114-knot cutback to make removal of pipe coating quicker and more cost effective. This special brush completes the three steps in the process of standard coating removal simultaneously. The brush cleans the pipe edge, removes the pipe coating and grinds the coating angle, all at one time.

“We wanted to solve a common issue in pipeline construction: preparing the coated pipes for welding. The ½ in thick coating has to be removed from the pipe end and leave an angle so that when welded together the pipe can be properly recoated to prevent corrosion,” said Jeff Naymik, the marketing manager at Osborn. “This special brush makes that long process much quicker and efficient.” Previously available only from suppliers in Europe, the cutback brush features a larger diameter and more knots than any brush currently produced in North America. The 114-knot brush is made with ultra-high-density, AB wire for heavy-duty applications such as pipe coating removal. The new brush is available in custom arbor hole/keyway dimensions.

Osborn also introduces a new catalog for its popular Load Runners® idler roller line. The 88-page four-color catalog offers specifications, diagrams, technical and application information, installation notes and quotation forms, as well as industry spotlights for a variety of industries. The Load Runners division manufactures a full line of cam followers, idler rollers and rail products in both metric and imperial, stud- or yoke-style, ranging in outside diameter sizes up to 12 in inside plain, flanged and V-groove design. In addition to its standard products, the company designs and manufactures customized products with special geometries, seals, lubrication and/or materials to exacting customer specifications. A four-page overview brochure also is available.
