Dewalt DW1150 Planer Idler Sprocket (Ref: 123240-00) – Bearing Upgraded

Eliminate Chain Slack & Feed Jamming with Needle Roller Bearing Precision

A worn or seized chain tensioner on your Dewalt DW1150 or DW1150K planer thicknesser causes chain slack, snatching, and erratic feed-roller movement that ruins timber surfaces. Because the original factory part (OEM 123240-00) is completely discontinued, finding a reliable, long-lasting replacement is critical to keep your machine running.

Designed and manufactured in the UK by a production engineer with over 30 years of precision CAD and tooling experience, this upgraded idler sprocket keeps your drive chain perfectly tensioned. Engineered with an integrated needle roller bearing, it completely replaces the prone-to-wear factory ABS part to deliver ultra-smooth, low-friction rotation and maximum lifespan.

Heavy-Duty Engineering & Performance Upgrades

• Direct Fit for Discontinued OEM Part #123240-00: Precision-modeled directly from the original Dewalt DW1150K Type 1 schematics for effortless drop-in installation.

• Upgraded Needle Roller Bearings: Replaces basic plastic-on-steel friction bushings with heavy-duty needle roller bearings, dramatically reducing heat buildup and drag on the motor.

• Mathematically True Sprocket Tooth Profile: Designed in high-end CAD to ensure flawless chain engagement without catching, link jump, or premature chain stretch.

• Upgraded Engineering Material: Printed in high-strength, impact-resistant industrial polymer that outclasses the original ABS component in fatigue resistance, torque handling, and wear life.

• Essential Chain Tensioning Performance: Maintains constant, reliable tension on the feed-roller drive chain to prevent timber stalling and severe chatter marks.
