About Ball and Roller Bearings

Ball Bearings

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 retaining ring have a removable retaining ring that holds the bearing inside a housing.

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.

Flanged Ultra-Thin Ball Bearings

Shielded

Flanged Bearing

Flanged and creating twice as many contact points as angular-contact ball bearings, these bearings ensure correct positioning within a tube or housing and resist radial loads.

Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.

Angular-Contact Thrust Ball Bearings

Open

Install these bearings for use with combined radial and thrust loads. They are often used in spindle applications and can be combined with cylindrical roller bearings to better handle radial loads.

Single-row bearings handle thrust loads on one side. For applications with thrust loads on both sides, mount them in pairs.

Open bearings dissipate heat more efficiently than shielded and sealed bearings.

Ultra-Thin Ball Bearings

Open

These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.

Open bearings dissipate heat more efficiently than shielded bearings.

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together. Bearings take on the shape of their housing and may be oblong prior to installation.

Open bearings dissipate heat more efficiently than sealed bearings.

One-Way Locking Needle-Roller Bearing Clutches

Triple Row

The needles in these bearings roll freely in one direction, but lock to transmit torque when the rotation of the shaft is reversed. Also known as drawn-cup roller clutches. An arrow on the lip indicates the rotational direction that locks the bearings.

Triple-row bearings support radial loads.

Bearings with 301 stainless steel springs handle higher temperatures than bearings with acetal springs.

Needle-Roller Thrust Bearings

Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings. Because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low-friction jobs. For use on hardened and ground surfaces.
