Gates Round Belt for Commercial Drives

This 9/16 in diameter round belt is built for commercial sewing machines, power-turn and line-shaft conveyors, serpentine drives and twisted drives. The reinforced solid gum-rubber core delivers the strength needed for continuous industrial power transmission.

Thermals Noise and Power Draw

Gum rubber construction with a rough surface texture maintains grip without excessive heat build-up during normal operation. The 80A hardness rating balances flexibility and wear resistance so the belt runs quietly and efficiently on minimum 5 13/32 in pulleys.

Endless Length Simplifies Installation

Supplied as an endless 308 in loop with a 26 ft inside length, the belt requires no splicing or lacing on site. This reduces downtime during replacement and ensures consistent tension from the first cycle.

Questions about this item

How do I install the 9/16 in diameter round belt on a commercial sewing machine, and what step is often missed?

Route the endless 308 in belt around the pulleys ensuring the minimum pulley diameter of 5 13/32 in is met; the step often missed is verifying the 80A hardness gum rubber seats fully in the groove without twisting.

What maintenance or replacement will the reinforced solid core belt need later?

Inspect the rough surface texture regularly for abrasion or cracking; replace the 26 ft inside length belt when the gum rubber hardens beyond 80A or the reinforced core shows fraying.

What limit appears first on the 308 in round belt during sustained conveyor use?

The 80A hardness gum rubber reaches its heat and flex fatigue limit first, causing surface glazing or core separation before the reinforced solid construction fails.
