About Ball and 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.

Sealed bearings block out dust better than open bearings, but retain more heat.

One-Way Locking Needle-Roller Bearing Clutches

Single Row

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.

Single-row bearings do not support loads from any direction. To support radial loads, use with our Needle-Roller Bearings.

Triple-row bearings support radial loads.

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

Precision Needle-Roller Bearings

Bearing

Shaft Liner

Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.

Open bearings dissipate heat more efficiently than sealed bearings.

Sealed bearings block out dust and other contaminants.

Shaft liners allow you to use the bearing on unhardened and unground shafts.
