How do I choose between 5M, 7M, and 11M rib spacing?

The cross-sectional designations (5M, 7M, 11M) represent the top width profile of the belt. Choosing the correct size requires balancing your precise mechanical power ratings with the space constraints of your machinery housing:

• 5M Profile (Top Width ~5mm): Engineered for ultra-compact drives, high-RPM light-duty operations, small medical equipment, precision spindle drives, and micro-machinery.
• 7M Profile (Top Width ~7mm): The general-purpose industrial workhorse. Ideal for medium power transmission applications including textile machinery, machine tool spindles, and advanced blowers.
• 11M Profile (Top Width ~11mm): Built exclusively for heavy-duty applications. Designed to handle severe high torque and massive power requirements in large machinery, industrial compressors, and heavy processing plants.
