Pillow block bearings are often used in low-torque, light loading applications. Pillow block units consist of a mounting bracket, or pillow block, that houses a bearing. The pillow block is secured to a foundation or workpiece while the shaft and inner ring of the bearing rotate freely. At Bearings Direct, our waterproof pillow block units are a thermoplastic design that is waterproof and of the highest quality by using stainless steel insert bearings and seals.
