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.

Thin-Profile Crossed-Roller Bearings
For a more compact machine, these bearings have thinner inner and outer rings than high-load crossed-roller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. 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.

High-Load Mounted Linear Ball Bearings for Support Rail Shafts
Designed to handle heavy loads, these bearings have higher load capacities than comparable standard mounted linear ball bearings for support rails.

Metric Clamping Lead Screw Collars
Thread these one-piece collars onto a metric lead screw to separate and position components, or use them as an end stop to limit travel. Made of black-oxide steel, they have mild corrosion resistance. Tighten the clamping screws to secure.
To ensure compatibility, please select a collar that has the same thread type, direction, size, pitch, and number of thread starts as your lead screw.

Bearing Retaining Locknuts
With a nylon insert that grips your threaded shaft or spindle without damaging its threads, these locknuts—also called shaft nuts—hold bearings, bushings, gears, and pulleys prone to vibration tightly in place. They come as one piece, so you can easily clamp them onto your shaft or spindle. But, since they aren’t made entirely of metal, they don’t stand up to heat as well as all-metal locknuts. Slots in their sides mean you can tighten and loosen them with a spanner wrench or spanner socket. Their face is also chamfered to help keep the size and weight of your assembly at a minimum. All meet international standards for bearing locknut dimensions.
When choosing your thread spacing, consider the precision of your application. The finer the threads, the more control you have when making adjustments.
All carbon steel locknuts are strong and resist wear, though they don’t stand up to corrosion as well as stainless steel locknuts. Zinc-plated steel locknuts resist rusting from some moisture, but you shouldn’t use them with salt water or chemicals.
303 stainless steel locknuts resist corrosion better than steel locknuts but aren’t as strong. They withstand washdowns and chemicals.

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.
Chamfered-face retaining nuts weigh less and produce less heat than stepped-face nuts. Some meet ISO 2982 (formerly DIN 981), an international standard for bearing locknut dimensions. Their sizes correspond to SKF KM series. Use them with DIN 5406 spring lock washers.
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.
