Custom abrasive filament brush roller with steel shaft

Custom Abrasive Filament Brush Rollers

Custom abrasive brush rolls made with silicon carbide, aluminum oxide, ceramic or diamond abrasive filament for industrial cleaning, deburring and surface treatment.

We manufacture custom abrasive filament brush rollers up to 600 mm in outside diameter and 6 m in overall shaft length, with single- or double-steel-band winding for OEM and replacement supply.

Abrasive Brush Rolls for Industrial Surface Treatment

An abrasive filament brush roller uses flexible nylon filaments containing abrasive grain throughout the filament. As the filament wears, new abrasive is exposed, maintaining a controlled brushing action for cleaning, oxide removal, deburring, surface conditioning and preparation across sheet, strip, plate and other wide workpieces.

Abrasive Filaments We Can Provide

Select the abrasive and grit for the workpiece and required finish. Filament diameter, carrier nylon and operating conditions are reviewed with the abrasive selection.

Custom abrasive filament brush rollers with different shaft-end designs

Silicon Carbide (SiC)

Grit 36 to 1000 for aggressive deburring, oxide or residue removal, and surface conditioning.

Aluminum Oxide

Grit 80 to 1000 for controlled polishing and finishing, particularly on steel and copper.

Ceramic Abrasive Filament

Grit 36 to 1000 for self-sharpening cutting, hard-metal deburring and controlled finishing.

Diamond Abrasive Filament

Grit 35 to 3500 for carbide, hard metal, stone and granite; a specialty option rather than the standard choice for steel-strip cleaning.

Identify the existing grit designation or applicable grit standard because the same grit number is not automatically interchangeable between abrasive systems.

Roller Construction and Supply Formats

Carrier Nylon, Core, and Shaft Options

Carrier nylon options include PA6, PA66, PA610, and PA612; PA610 and PA612 are commonly reviewed for wet operation.
Supply formats include a complete roller with finished shaft ends, a hollow replacement sleeve, or an internally welded brush package for the customer’s retained shaft.
Shaft and tube choices include carbon or stainless steel. Aluminum, PVC, PP, or HDPE cores can be reviewed for suitable designs, and reusable steel shafts or cores can be inspected for re-bristling.

Single- and Double-Steel-Band Winding

Band construction is selected according to fill retention, density and contact duty:

Single steel band — flexible fill and controlled coverage for lighter contact
Double steel band — stronger retention and higher density for coarse fill, heavier contact or continuous duty

For replacement supply, identify the existing construction or send a clear end view with the roller drawing.

Applications in Steel Strip, Sheet and Process Lines

Strip degreasing and rolling-residue removal
Scale and oxide removal around pickling and annealing processes
Surface activation before coating, galvanizing, tinning, or cladding
Sheet, strip, and plate conditioning or polishing
Aluminum and copper strip surface preparation

Filament polymer and roller construction are selected for the exact line position, process chemistry, contact requirement, and wet or dry conditions.

One-Piece Rollers up to 6 m Overall Shaft Length

The 6 m capability refers to overall shaft length, not automatically to the working brush face. Send the complete roller or machine drawing so the brush face, shaft and core design, journals, keyways, bearing arrangement, operating speed and support arrangement can be reviewed.

Made to Drawing for OEM and Replacement Supply

A drawing is required for OEM or replacement orders. Include the following information; photos and samples may be provided as supporting references:

Outside diameter, brush face, overall length, shaft ends, and mounting details
Abrasive, grit, filament diameter, trim length, fill pattern, and band construction, if known
Workpiece material, required surface result, and wet or dry operation
Process chemical, concentration, and temperature for wet lines
Operating speed, rotation direction, and any customer-specified runout, balance, test, or inspection requirements
Required quantity and repeat-order forecast

Feasible inspection criteria and records are agreed before production. Provide the roller drawing and use clear photos or an existing sample to help clarify the specification. Photos or samples do not replace the required drawing.

Abrasive Filament vs. Non-Woven and Wire Brush Rollers

An abrasive filament roller uses individual polymer filaments containing abrasive grain. It provides flexible contact for cleaning, deburring and controlled surface treatment.

A non-woven abrasive roller brush uses bonded abrasive web or disc material for blending and controlled finishing.

A wire brush roll uses metal wire for more aggressive scale removal and wire-brushing duties. Spiral-wound brush rollers can use either wire or abrasive filament, depending on the application.

Abrasive filament brush rollers from the Shanghai aluminum rolling mill replacement project

Installed Aluminum Rolling Mill Replacement

For an aluminum rolling mill in Shanghai, we measured the existing roller and reviewed its fill before recommending an SiC abrasive-filament replacement.

The customer ordered and installed 16 rollers of approximately 1.2 m each, demonstrating drawing- and sample-based replacement supply.

Custom Abrasive Brush Rolls Made to Your Drawing

A drawing is required. Include the workpiece, process conditions, required surface result, operating speed, and quantity. Minimum order: 2 rollers. Production lead time: 15–20 days after order and drawing confirmation, plus shipping time.
