Thrust Ball Bearings
Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components. With an open design, they dissipate heat more efficiently than one-piece thrust ball bearings.
Bearings with steel cage and with bronze cage handle higher loads and speeds than bearings with a plastic cage.

High-Temperature Dry-Running Sleeve Bearings
Graphite provides a layer of dry lubrication that operates in high-temperature environments.
932 bearing bronze bearings are cast, making them strong, wear resistant, and excellent at handling shock loads. They are sometimes called 660 leaded bronze bearings.
Grooved bearings have a graphite-filled groove on the inside of the bearing that distributes lubricant evenly along the bearing’s surface.
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.

Multipurpose Sleeve Bearings with Groove
A figure-8-shaped groove provides a flow path for lubricant, distributing it evenly along the bearing’s surface. Bearings are cast bronze, making them strong, wear resistant, and excellent at handling shock loads. 932 bearing bronze is sometimes called 660 leaded bronze.

Linear Bearings for Ball 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.
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. Those with a step-down end have a shoulder near the end to stop gears, sprockets, and bearings.

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.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.

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. 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.

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.

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.
