Value Collection 12L0506FSFB1/2 Timing Belt Pulley

Product Description

The VALUE COLLECTION 12L0506FSFB1/2 is a 12-tooth timing belt pulley designed for synchronous drive applications in light industrial and mechanical power transmission systems. It features a 1/2 inch inside bore diameter and a 1.402 inch outside diameter, with a pitch diameter of 1.432 inches. The pulley is sized for L-series timing belts with a 1/2 inch belt width and a 0.75 inch face width. Constructed from steel cast iron, this pulley provides the rigidity and wear resistance required for consistent belt engagement under repetitive load cycles. Installation is performed by mechanical technicians and millwrights working on conveyor, indexing, or motion control systems.

This pulley fits applications that use L-series (3/8 inch pitch) synchronous timing belts with a 1/2 inch width. It is suited for light-duty industrial drives, small conveyor systems, and OEM machinery where precise timing and positional accuracy are required. The 12-tooth count and 1.432 inch pitch diameter make it appropriate for compact drive arrangements with moderate speed ratios. Both original equipment builds and field replacement installations are common use cases for this pulley configuration.

Key Features

• 12-tooth profile for L-series timing belt engagement
• 1/2 inch bore diameter for direct shaft mounting
• 1.402 inch outside diameter and 1.432 inch pitch diameter
• 0.75 inch face width accommodates 1/2 inch wide L-series belts
• Steel cast iron construction for durability and dimensional stability
• Single-piece pulley design suitable for OEM and replacement use

Compatibility

Designed for use with L-series synchronous timing belts with a 1/2 inch belt width. Verify bore diameter, pitch diameter, and tooth count against the driven shaft and belt specifications before installation.

Installation Notes

Installation is typically performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before removing or installing any pulley. Ensure the shaft diameter matches the 1/2 inch bore and that the belt is properly tensioned per the belt manufacturer's guidelines. Misalignment between the driving and driven pulleys can cause premature belt wear and should be checked with a straightedge or laser alignment tool before returning the system to service.
