PMI

Ballscrews and precision guides

Roller is an official PMI distributor, a brand specialising in the production of ballscrews and precision guideways. We chose to be a PMI distributor due to their emphasis on continuous product improvement.

PMI manufactures ballscrews under stringent quality conditions, at a constant temperature of 20º C, to ensure the high precision of this product. These ballscrews are made of German Alloy steel, treated to provide good rigidity, with a surface hardening treatment that ensures long durability.

PMI precision guideways have a very low friction coefficient and a very small variance between dynamic and static friction.
