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 Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

Sealed Bearing—Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

Shaft Liners for Precision Needle-Roller Bearings

Adapt high-precision needle-roller bearings to use on unhardened, unground shafts. The liner fits between the roller and the shaft.

One-Way Locking Needle-Roller Bearing Clutches

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

Triple-Row Bearing—Triple-row bearings support radial loads.

301 Stainless Steel Springs—Bearings with 301 stainless steel springs handle higher temperatures than bearings with acetal springs.

Precision Needle-Roller Bearings


	Bearing

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

Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

Sealed Bearing—Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

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