For Business-Critical Continuity

Liebert DS Belts

Liebert DS models incorporate an automatic self-tensioning

motor base which keeps constant tension on belts while 

maintaining good sheave and pulley alignment. 

As part of the improved air delivery system, Liebert

developed a new belt offering for the DS. This improved

belt design increases belt life and reduces belt dust.

Key Features 

Cord tensile strength 18% stronger

than a conventional belt, which

provides greater strength and

superior stretch resistance.

100% neoprene rubber compound

increases belt strength while

reducing belt wear and improving

flexibility.

Belt temperature runs cooler with

better heat dissipation, improving

belt life.

Liebert belts are machined,

matched and tagged as a set 

for optimal life performance.

Belt design and material reduce

belt dust.

Polyester cords maintain

extreme belt load and

shock without stretching.

Four fabric plies top and

bottom relieve stress on

load-carrying cords for

added flexibility.

100% neoprene rubber 

compound supports cords, 

dissipates heat and provides

oil, heat and ozone resistance.

Raw-edge belt sidewalls grip

pulleys better to minimize belt

slip, noise and drive vibration.
