Tapped-Base Mounted Ball Bearings

Smoother than smooth—the balls roll nearly friction-free within a sturdy housing to support shafts as they turn. These bearings mount from the bottom through threaded holes. With a narrow profile, they're a good fit for cramped spots where multiple shafts are mounted close together.

Lubricate regularly to keep your bearing in tip-top shape. These bearings come packed with grease and sealed to block out dust and contaminants.

Powder-Coated Cast Iron Housing—A rugged iron base coated in thick powder that protects against water, mild detergents, and oil. However, if the coating is scratched or chipped, the underlying iron may rust.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.

Clamp On—Tighten the clamping screw to close the collar around your shaft for a secure, mar-free grip. The collar centers the shaft, decreasing vibration and allowing for higher speeds than set screws. Also known as concentric lock bearings.

Sealmaster—Famous for exceptional sealing, Sealmaster bearings include a signature three-part seal in the inner ring. This design blocks out gritty debris and purges old grease to extend the life of the bearing.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

Food-and-Beverage Permanently Lubricated Tapped-Base Mounted Ball Bearings

Reduce upkeep on your food line with bearings that never need lubrication. On startup, an oil-infused solid polymer releases the optimal amount of food-safe, NSF-registered lubricant—never too much or too little. The embedded oil never leaks out, and seals keep dust and contaminants from sneaking in. Install them into conveyors, packaging systems, and other food processing applications where contact with ingredients is rare but possible. The balls roll nearly friction-free within a sturdy housing to support shafts as they turn. These bearings mount from the bottom through threaded holes. With a narrow profile, they're a good fit for cramped spots where multiple shafts are mounted close together.

Plastic-Coated Cast Iron Housing—Combines the structural strength of cast iron with the natural rust resistance of plastic.

Set Screw—Turn the screw to lock your shaft in place. A simple, reliable choice, set screws grip tightly, but they can mar shaft surfaces.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.
