Sia 2925 sialoX 4 x 24 in 120 Grit Cloth Belt

Description

The Sia 2925 120 Grit Belt is a 4 x 24 inch cloth-backed abrasive for general metal sanding on compatible belt machines. This straight belt uses aluminum oxide grain on a durable X-weight cloth backing, giving fabrication and maintenance teams a practical choice for smoothing, blending, rust removal, weld preparation, and final sanding on non-ferrous metals and unalloyed or low-alloy steel.

Fitment and Sanding Use

Confirm a 4 x 24 inch belt size before ordering. The 120 grit grade sits in the medium-to-fine part of the 2925 sialoX range, making it useful after heavier stock removal and before finer finishing steps. The cloth backing supports edge stability and tear resistance as the belt travels around the machine. Sia lists the family for both dry and wet sanding applications, including stationary contact-belt work and portable belt use where the machine accepts this exact belt size.

What the 120 Grit Grade Does

This grade can blend sanding marks, clean light oxidation, refine weld-preparation areas, and establish a more uniform surface before the next finishing step. Aluminum oxide grain and resin-over-resin bonding provide an all-purpose cutting surface for common fabrication work. Use appropriate guarding, dust extraction, eye protection, and the machine manufacturer’s operating limits. Match belt direction, dimensions, and grit to the workpiece and existing process before production use.
