YS 591 Ceramic X Weight Cloth Belt with Top Coat

Good

YS 591 is a ceramic aluminium oxide belt on X-weight heavy polyester with supersize top coat, built for centreless linishing on stainless tube, bar stock, high-carbon steel, and titanium. X-weight polyester provides greater elongation resistance than Y-weight under continuous centreless grinding tension, which means the belt holds its dimensional geometry — and consistent Ra values — from the first component processed to the last in a batch run.

Product Information

Features

- Ceramic aluminium oxide grain on X-weight heavy polyester backing with supersize top coat

- Close coat, wet and dry compatible, centreless linishing and backstand grinder compatible

- Engineered for stainless tube, bar stock, and titanium finishing where consistent Ra values are required

Benefits

- X-weight polyester provides greater elongation resistance than Y-weight under continuous centreless grinding tension — belt geometry stays stable, Ra finish stays consistent

- Ceramic grain self-sharpens at the contact zone — surface finish is repeatable from the first component to the ten-thousandth

- Supersize coat reduces friction heat at the interface, preventing thermal discolouration on SS316L, duplex stainless, and titanium alloys

Advantages

- X-weight specification is correct for centreless operations where belt stretch causes tracking deviation and Ra variation — Y-weight is insufficient for this application

- Supersize coat is the specification required when stainless tube or bar finish is cosmetically specified and thermal discolouration causes rejection
