Dayton

Dayton 2CNK1 Linear Ball Bushing Bearing, Closed, 1/2 in Bore

SKU CH-TDWF-5BVB4

Linear ball bearing with 1/2 inch bore, 7/8 inch outside diameter, 114 lbf dynamic and 176 lbf static load capacity

  • Closed design keeps contamination out
  • Stainless steel and polymer cage resists corrosion
  • 114 lbf dynamic load handles linear motion forces
  • 176 lbf static load supports stationary weight
  • Operates from -4 to 176 °F for wide temperature range

Product Identity

The Dayton 2CNK1 is a closed linear ball bushing bearing with a 1/2 inch bore designed for inch-measurement linear motion systems. It suits engineers and maintenance teams who need a ready-to-install bearing for precise shaft guidance in machinery and automation equipment.

Capacity and Headroom

The bearing delivers a dynamic load capacity of 114 lbf and a static load capacity of 176 lbf, providing reliable support for moderate radial loads in continuous operation. It operates within a temperature range of -4 to 176 degrees Fahrenheit and maintains performance at steady state speeds up to 5000 inches per minute.

Interface Limits

The 1/2 inch inside diameter with a tolerance of +/- .001 inch and 7/8 inch outside diameter define the shaft and housing fit requirements for this closed-type bearing. Its stainless steel and polymer cage construction sets the material boundary for corrosion resistance and operating temperature limits without self-alignment capability.

Highlights

  • Closed design keeps contamination out
  • Stainless steel and polymer cage resists corrosion
  • 114 lbf dynamic load handles linear motion forces
  • 176 lbf static load supports stationary weight
  • Operates from -4 to 176 °F for wide temperature range

Questions about this item

Will the 1/2 in bore and 7/8 in outside diameter fit the shafts and housings I already use?

The bearing has a 1/2 in inside diameter with a ±.001 in tolerance and a 7/8 in outside diameter, so it matches standard inch-series shafts and housings of those sizes.

How can I confirm the bearing is running correctly once installed?

After installation, the shaft should rotate smoothly without binding, and the bearing should stay within the -4 °F to 176 °F temperature range while operating up to 5000 in/min.

Does the closed ball bushing come pre-lubricated or do I need to supply grease and seals separately?

The unit is a closed-type linear ball bearing with a stainless-steel/polymer cage; lubrication and any additional seals are not included and must be sourced separately.
