High-Load Crossed-Roller Bearings
The thicker inner and outer raceways on these bearings can handle heavier loads than the thin-profile crossed-roller bearings. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.
Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

Ultra-Low-Friction Oil-Embedded Thrust Bearings
For applications with frequent starts and stops, the oil in these bearings contains particles of slippery PTFE that lubricate the bearing during startup.
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.

Food Industry Oil-Embedded Thrust Bearings
The oil in these bearings is NSF registered H1 and FDA compliant for incidental contact with food. Startup friction causes them to release a thin layer of oil on the bearing’s surface.

High-Load Food Industry Oil-Embedded Thrust Bearings
Made of 863 iron-copper and embedded with NSF registered H1 oil, these bearings can tackle high-load applications in food plants, such as bottling and filling lines. Startup friction causes these bearings to release a thin layer of oil onto their surface. The oil is safe for incidental contact with food. Also known as Super Oilite® bearings, these bearings have high iron content, so they’re strong and hold up to shock loads.

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. 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.

Ring Shims
Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Stainless steel shims are more corrosion resistant than steel shims. 316 stainless steel shims have the best corrosion resistance of our stainless steel shims.
Carbon steel shims have excellent strength and can be welded, but aren't as corrosion resistant as other shims.
Spring steel shims are comparable in strength to carbon steel shims, but are harder and hold their shape better. They aren't as corrosion resistant as other shims.
Aluminum shims are lightweight and nonmagnetic. They have good corrosion resistance.
Brass and copper shims are corrosion resistant and nonmagnetic. Copper shims are good conductors of heat and electricity, so these shims are often used when installing heat sinks.
PTFE plastic shims are slippery, so they can be used to reduce friction between parts. They also have excellent chemical resistance.

Bearing Retaining Nuts
Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle. They have slotted sides, so you can tighten and loosen them with a spanner wrench or spanner socket.
Use stepped-face retaining nuts with DIN 462 spring lock washers. You can also use them in pairs or with other bearing retaining nuts as jam nuts. For the nut closer to the bearing, position the stepped face towards the bearing. All meet DIN standards for bearing lockout dimensions.
Carbon steel retaining nuts are strong and resist wear.

Bearing Retaining Jam Nuts
Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle. Threading two nuts tightly against each other makes it harder for vibration to loosen your assembly than if you used only one nut. For the nut closer to the bearing, position the stepped face towards the bearing. These jam nuts have holes on the side, so you can tighten and loosen them with a pin spanner wrench. Made of carbon steel, they’re strong and wear resistant. All meet DIN 1816, an international standard for bearing locknut dimensions.

Washdown Clamping Shaft Collars
Suitable for use in washdown applications, these plastic collars also offer good chemical resistance. They clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screw to secure.
Acetal collars have a naturally slippery surface and resist swelling when exposed to moisture.
