Mechanical Components

Mechanical components transmit power and motion throughout industrial machines. Belts, sheaves, bushings, bearings, couplings and shaft collars all work together, and one failed part can stop a whole line.

Belts

Belts are the simplest way to transmit power between shafts in conveyors, fans, pumps, compressors and machine drives. Choosing the right belt type and size keeps drives efficient, quiet and low-maintenance.

Belt Types

Classical V-belts (A, B, C) – the standard for general industrial drives
Narrow wedge belts (3V, 5V, 8V) – more power in a smaller drive
Cogged V-belts – run cooler and flex around smaller sheaves
Timing and synchronous belts – no slip, for precise speed and positioning
Banded and multi-rib belts – reduce belt whip on multi-belt drives

Belt Selection & Care

Match the belt cross-section to the sheave grooves and confirm the length from the part number printed on the old belt. On multi-belt drives, replace all belts as a matched set. Check tension after the first 24 hours of running, and replace worn sheaves to stop premature belt wear.

Centro carries V-belts, timing belts and the sheaves and bushings to go with them.
