Product Description
The Timken Fafnir cast iron pillow block with eccentric collar locking is the go-to mounted bearing unit for industrial, agricultural, and material handling applications. Available across 6 housing series with shaft sizes from 1/2″ to 3-15/16″ , these units combine Timken’s precision insert bearings with rugged cast iron housings for reliable, long-lasting performance. Unlike set screw designs that can mar the shaft or loosen under vibration, the eccentric collar uses a cam-action locking mechanism that grips the shaft concentrically with a single wrench.
