Use where high loads and speeds are not required.

Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

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.

Bearing with Retaining Ring Grooves

Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included). For bearings with retaining ring grooves, secure with two retaining rings (sold individually).

Bearings with end seals keep lubricant in and dust out.

Bearings with stainless steel balls are more corrosion resistant than bearings with steel balls.

Fixed-alignment bearings are for use where shaft misalignment is unlikely.

Linear Bearings for Ball Splines

For Four Splines

Combine these bearings with a ball spline to create a compact linear and rotary motion system for applications with fast, complex movements, such as robotics. These bearings move smoothly and precisely even at high speeds along ball splines while grooves on the ball spline transmit rotary power. Clip a retaining ring into the groove on these bearings to position them in your system. Use the keyway and included machine key for attaching your load.

Stainless steel bearings are more corrosion resistant than steel bearings.

Splines are alloy steel for high strength and wear resistance. They're hardened only on the outside, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads.

Mounted Linear Bearings for Ball Splines

A flange with mounting holes makes it easy to attach a load to these bearings. Create a compact linear and rotary motion system for robots and other applications requiring complex, fast movements, by combining them with ball splines. These bearings move smoothly and precisely even at high speeds along ball splines while grooves on the ball spline transmit rotary power. Clip a retaining ring (not included) into the groove on these bearings to position them in your system.

Metric Press-Fit Drill Bushings

Also known as jig bushings, these metric drill bushings fit inside fixture plate holes to guide drill bits, counterbores, reamers, and other cutting tools. They improve accuracy so that your drilled holes and cuts are consistent from part to part. Known for their versatility, drill bushings are also used as spacers, shims, and machinery bushings. These bushings are made of hardened, ground steel that holds its shape and resists wear, so they last for many cycles without needing to be replaced.

All bushings have a chamfer on the outside that centers the bushing as you place it into the hole. Press into place with a manual or hydraulic press. They also have internal chamfers, so it's easier to insert bits, pins, and punches into the bushing. Some bushings have internal chamfers on both ends, so no matter which end of the bushing is inserted into your jig, your bits, pins, and other tooling enter easily. Having an internal chamfer on the bottom of your bushing may cause shavings to get caught and bind as you remove the bit, however.

DIN 179 bushings meet dimensional and material standards that make sure they're compatible with other parts and tools. Although DIN 179 is no longer an active standard, it's still a common reference point for designers.

Metric Press-Fit Drill Bushings with Head

Shown in Countersunk Hole

Shown in Standard Hole

Even under extreme drilling pressure, these metric bushings won't press through your jig plate. A flanged head on the top of the bushing acts as a stop, preventing it from moving as you push down your drill bit, reamer, or other cutting bit. Drill bushings ensure accurate, consistent cuts and drilled holes from one part to the next. They sometimes also work as spacers, shims, and machinery bushings. Made of hardened, ground steel, these bushings hold their shape and resist wear over time. The flanged head protects your jig plate from damage caused by heavy use.

Although it's no longer an active standard, DIN 172 is still a common reference point for making sure parts are compatible with other parts and tools.

These bushings work in both countersunk and standard drill holes. To install, place the bushing inside the hole in your jig. A chamfered edge on the bottom of the bushing helps center the bushing in the hole. Once centered, press the bushing into the hole with a hydraulic or lever press.

Quick-Disconnect (QD) Bushings

Machinable

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

304 stainless steel bushings resist corrosion from washdowns and humidity, so they’re common in food-processing plants and other frequently-cleaned areas. You can machine the center of these bushings to fit the exact dimensions of your shaft.
