About Shaft Collars
Shaft collars are useful for holding and positioning components on a shaft. They can also serve as mechanical stops and stroke limiters.

Ultra-Thin Ball Bearings
These bearings have twice as many contact points as angular-contact ball bearings. Fit onto large-diameter hollow shafts to run air and hydraulic lines, electrical wiring, and other components through moving parts in assemblies such as index and rotary tables, packaging equipment, and robotics.
Open bearings dissipate heat more efficiently than shielded bearings.

Oil-Embedded Thrust Bearings
Startup friction causes these porous bronze bearings to release a thin layer of oil on the bearing’s surface. They are also known as Oilite® bearings.
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 Thrust Bearings
Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings. Because of the large contact area between the rollers and washers (not included), these bearings are great for medium to heavy duty, low-friction jobs. For use on hardened and ground surfaces.
Washers allow you to use the bearing on unhardened and unground surfaces.

Bearing Retaining Locknuts
With a nylon insert that grips your threaded shaft or spindle without damaging the threads, these locknuts—sometimes called shaft nuts—keep bearings, bushings, gears, and pulleys in place. They won’t shake loose from vibration. However, their nylon insert also means you shouldn’t use these locknuts in applications with high temperatures. Their sides are slotted, so you can tighten and loosen them with a spanner wrench or spanner socket. To reduce the total size and weight of your assembly, they have chamfered edges.
All meet international standards for bearing locknut dimensions.
Carbon steel locknuts are strong and wear resistant. 303 stainless steel locknuts are nearly as strong as carbon steel but won’t rust in outdoor, washdown, and other corrosive environments.
When choosing your thread spacing, consider the precision of your application. The finer the threads, the more control you have when making adjustments.
