McMaster-Carr Deep Groove Ball Bearings

1166 Products

Deep groove ball bearings are the most widely used bearing type and are particularly versatile.They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.

Permanently Lubricated Ball Bearings

Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing. Sealed bearings have even better resistance to dust and contaminants than open bearings.

High-Load Ball Bearings

High-Load Ball Bearings

With a wider profile than standard ball bearings, these rugged bearings are good for handling heavy loads at low speeds. Open bearings dissipate heat more efficiently than shielded and sealed bearings. Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings. Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat. Bearings with extended inner ring provide additional shaft support. Bearings with retaining ring have a removable retaining ring that holds the bearing inside a housing.

Precision Ball Bearings

Precision Ball Bearings

For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings. Shielded bearings dissipate heat more efficiently than sealed bearings. Sealed bearings block out dust and other contaminants better than shielded bearings.

Light Duty Ball Bearings

Light Duty Ball Bearings

Use these bearings where high speed and precision are not a concern. Open bearings dissipate heat more efficiently than shielded and sealed bearings. Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings. Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.

Electrically Insulated Ball Bearings

Electrically Insulated Ball Bearings

Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently. Shields keep out dust and contaminants.

Hex-Bore Ball Bearings

Hex-Bore Ball Bearings

Mount these bearings onto a hex shaft. All have an extended inner ring for additional shaft support. Seals keep out dust and contaminants.

Permanently Lubricated Stainless Steel Ball Bearings

Permanently Lubricated Stainless Steel Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing. Sealed bearings have even better resistance to dust and contaminants than open bearings.

Stainless Steel Ball Bearings

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance. Open bearings dissipate heat more efficiently than shielded and sealed bearings. Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings. Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat. Bearings with extended inner ring provide additional shaft support.

Precision Stainless Steel Ball Bearings

Precision Stainless Steel Ball Bearings

Made to tight tolerances, these 440C stainless steel bearings combine speed and accuracy with corrosion resistance. Open bearings dissipate heat more efficiently than shielded bearings. Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Food Industry Permanently Lubricated Stainless Stell Ball Bearings

Food Industry Permanently Lubricated Stainless Stell Ball Bearings

Good for applications with incidental food contact, these 440C stainless steel bearings have a food-grade, solid polymer lubricant between the balls and ring that eliminates the need for additional lubrication. The solid lubricant blocks out water and dust, extending the life of the bearing. Sealed bearings have even better resistance to dust and contaminants than open bearings.

Ultra-Corrosion-Resistant Stainless Steel Ball Bearings

Ultra-Corrosion-Resistant Stainless Steel Ball Bearings

These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.
