Mounted Ball Bearings with Four-Bolt Flange

Smoother than smooth—the balls inside these bearings roll nearly friction-free. The four-bolt flange supports shafts with a stronger connection to the mounting surface than two-bolt alternatives.

Lubricate regularly to keep your bearing in tip-top shape. Bearings with seals keep lubricants in and contaminants out, and come packed with grease. Open bearings require initial lubrication and offer less protection against dust and debris.

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.

Nickel-Plated Cast Iron Housing—Combine the strength of iron with the corrosion resistance of stainless steel at an affordable price point. Nickel-plated iron is also unlikely to chip.

Polyester Plastic Housing—Lightweight and naturally rust-resistant, with a smooth surface that's easy to wipe clean.

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.

Eccentric Lock—An off-center opening wedges against the shaft to grip it as it turns. Eccentric locks won't mar the shaft like a set screw, but the shaft will only rotate in one direction, so they aren't suitable for applications where the load will be reversed.

Locknut—Tighten the nut for a strong hold that stands up to heavy vibrations without letting go. An adapter sleeve is required and sold separately.

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.

SKF—Manufactured in Europe with a strong focus on precision. The more precise the bearing, the more efficiently it will run.

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.

Mounted Tapered-Roller Bearings with Four-Bolt Flange

Support heavier loads than mounted ball bearings, but at lower speeds. These bearings also withstand thrust loads, which are forces acting parallel to the shaft. The four-bolt flange supports shafts with a stronger connection to the mounting surface than two-bolt alternatives.

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

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.

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. The four-bolt flange creates a stronger connection to the mounting surface than two-bolt alternatives.

316 Stainless Steel Housing—The most corrosion-resistant metal we offer, these housings hold up to harsh chemicals and salt water.

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.

Food-and-Beverage Mounted Ball Bearings with Four-Bolt Flange

With NSF-registered H1 grease, these bearings are safe for use on food and beverage lines. 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. The four-bolt flange creates a stronger connection to the mounting surface than two-bolt alternatives.

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

Plastic Housing—Lightweight and naturally rust-resistant, with a smooth surface that's easy to wipe clean.

300 Series Stainless Steel Housing—Prevent rust from exposure to moisture and mild chemicals, including ammonia-based cleaning solutions.

316 Stainless Steel Housing—The most corrosion-resistant metal we offer, these housings hold up to harsh chemicals and salt water.

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.

SKF—Manufactured in Europe with a strong focus on precision. The more precise the bearing, the more efficiently it will run.

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.

Closed Caps—Mount on the end of the shaft to block out debris and prevent accidental contact with rotating parts.

Open Caps—Install anywhere along the shaft to block out debris and prevent accidental contact with rotating parts.

Extreme-Temperature Mounted Sleeve Bearings with Four-Bolt Flange

From cryogenic chill to heat-treating furnaces, these bearings endure it all. Made to glide in temperatures from -400° to 750° F, they support shafts in conditions that seize or destroy other bearings. With graphite lubricant that never degrades, they require little to no maintenance.

With no moving parts, sleeve bearings stand up to dusty, dirty conditions better than ball bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing's four-bolt flange supports shafts with a stronger connection to the mounting surface than two-bolt alternatives.

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.

High-Temperature Mounted Ball Bearings with Four-Bolt Flange

Packed with heat-stable synthetic grease, these bearings keep their cool when machinery runs hot. Install them in applications as hot as 400° F, where standard, mineral-based lubricants would burn off. The balls roll nearly friction-free within a sturdy housing to support shafts as they turn. The four-bolt flange creates a stronger connection to the mounting surface than two-bolt alternatives.

Lubricate regularly to keep your bearings in tip-top shape. These bearings are sealed to block out dust and contaminants.

Dry-Running Mounted Ball Bearings with Four-Bolt Flange

Leave the lubricant in the supply closet—these low-maintenance bearings are made from naturally slippery plastic. They'll keep shafts spinning with no messy grease to drip off, wash out, or collect dust. The balls roll nearly friction-free within a sturdy housing to support shafts as they turn. The four-bolt flange creates a stronger connection to the mounting surface than two-bolt alternatives.

Bearing Guards

For Four-Bolt-Flange-Mount

Bearings

Cover base-mount or flange-mount bearings to protect personnel from injury and keep contaminants out. Place guards over the entire bearing housing and drill holes in their flange to install with screws. If necessary, drill the guards for access to bearing grease fittings or to create space for a shaft to pass through, and trim the flange to fit in tight spaces.

Black—Black ABS guards resist UV light, so they won’t color or crack when exposed to the sun.
