Description

Martin Pulley – 2SPB170+ & 2SPB160+

Manufactured: Martin (Martin Sprocket & Gear)

Product Type:  Pulley

Product Tag: 2SPB170+, 2SPB160+

 

General Information

Taper Bushed Martin Pulley, a device used in mechanical transmission systems. To transfer torque from the drive shaft to the belt or chain. Designed to be used in conjunction with bushing, Taper Bushed Martin Pulley is used in a variety of industries, such as manufacturing, transportation, and automotive. When choosing, you should consider the size of the shaft. Belt type and rotational speeddesired to achieve the most suitable and efficient equipment

 

Materials Information

• Base Metal: High-grade GG25 gray cast iron (ISO 185 standard).
• Tensile Strength: Minimum tensile strength rating of 250 N/mm².
• Hardness Profile: Measures between 180 and 250 HB (Brinell) to resist groove wear.
• Surface Finish: Treated with a protective black phosphate conversion coating for rust prevention.

 

Features

• Vibration Dampening: Flake graphite microstructure naturally absorbs heavy operational machinery vibrations.
• Interchangeability: Built to international metric standards for global component swapability.
• Slip-Fit Mounting: Taper bushing design creates a high-torque shrink fit without scoring shafts.
• True-Running: Precision-machined grooves prevent belt twisting and minimize lateral belt wear.
