National 205-SS Clutch Pilot Bearing

Overview of National 205-SS Clutch Pilot Bearing

The National 205-SS clutch pilot bearing is engineered for reliable performance in transmission systems requiring precise alignment and smooth operation. Designed as a single row radial ball bearing, it supports the input shaft of the transmission, ensuring proper clutch function in vehicles such as Ford, Chevrolet, and Dodge models.

• Single row radial ball bearing design for consistent load handling
• Inner race bore diameter of 0.984 inches (25.000 mm) for accurate fitment
• Outer race outside diameter of 2.047 inches (52.000 mm) for secure housing placement
• Width of 0.591 inches (15.000 mm) providing compact and efficient bearing profile
• Inner and outer race radius of 0.040 inches (1.020 mm) to reduce stress concentrations
• Part number 205-SS for precise identification and replacement

Technical Specifications and Design Details

The National 205-SS clutch pilot bearing features a 200 series, type A-3 ball bearing construction. Its single row radial design supports radial loads typically encountered in clutch assemblies. The inner race bore of 0.984 inches (25 mm) matches common input shaft diameters found in many domestic vehicles, including Ford F-150, Chevrolet Silverado, and Dodge Ram trucks. The outer race diameter of 2.047 inches (52 mm) ensures compatibility with standard transmission housings. With a width of 0.591 inches (15 mm), this bearing maintains a low profile while providing durability and smooth rotation.

Applications and Problem Solving

This clutch pilot bearing is used primarily to support the transmission input shaft and align the clutch disc during engagement and disengagement. It addresses several common issues:

• Reduces input shaft wobble and misalignment
• Minimizes clutch chatter and vibration
• Prevents premature wear of transmission components
• Ensures smooth clutch engagement and disengagement
• Supports proper transmission input shaft rotation

Installation Notes and Tips

When installing the National 205-SS clutch pilot bearing, ensure the transmission input shaft and housing are clean and free of debris. Use appropriate tools to press the bearing evenly into the housing without damaging the races. Verify the bearing is fully seated and rotates smoothly before reassembling the clutch components. Lubrication should be applied according to vehicle manufacturer specifications to maintain bearing performance.

Quality Assurance and Warranty

National bearings are manufactured to meet industry standards for durability and precision. The 205-SS clutch pilot bearing undergoes rigorous quality control to ensure consistent performance in demanding automotive environments. While specific warranty terms may vary, National typically offers coverage against manufacturing defects to provide confidence in product reliability.
