16Teeth Perlin Pulley GT2 with teeth 3mm Bore for Belt 6mm Idler Wheel راس استيبر 20 سن - 6 مل

Pulley Type

GT2 Smooth Idler Pulley (Toothless Idler / Passive Pulley)

Tooth Profile

Smooth/No teeth (designed to run on the back/smooth side of a GT2 belt, or for guiding the toothed side without engaging teeth)

Tooth Pitch

2mm (refers to the compatible belt's pitch)

Equivalent Teeth

16 Teeth (This typically refers to the outer diameter of the pulley, which is similar to a 16-tooth GT2 geared pulley. It does not mean it has teeth.)

Belt Width Compatibility

Designed for 6mm wide GT2 timing belts

Bore Diameter

3mm (inner diameter, for mounting on a 3mm shaft)

Outer Diameter (OD)

Approximately 12.5mm - 13mm (similar to a 16-tooth GT2 geared pulley)

Overall Height/Length

Approximately 8.5mm - 10mm (can vary slightly by manufacturer)

Material

High-Quality Aluminum Alloy (common for durability and smooth surface)

Flanges

Dual flanges (to keep the belt properly aligned and prevent it from slipping off)

Bearings

Typically includes 1 or 2 miniature ball bearings (e.g., 623ZZ or similar) for smooth, low-friction rotation.

Shaft Fixing

Usually slips onto the shaft; may or may not include grub screws (since it's an idler, it doesn't transmit torque via the shaft, but rather rotates freely on it). Some designs might have an integrated shaft or bolt.

Precision

High precision bearings ensure smooth, quiet operation and minimal friction. Essential for maintaining belt tension and guiding.

Weight

Very lightweight, typically 3g - 6g
