Stainless steel linear ball bearing with polymer cage, closed type, 3/4 inch bore

Dayton

Dayton 2CNK8 Linear Ball Bearing Closed 3/4 in Bore

SKU CH-F8T6-XQ4NT

Closed linear ball bearing with a 3/4 in bore, self-aligning design, 470 lbf dynamic and 600 lbf static load ratings, operating from -4 to 176 °F

  • Self-aligning design compensates for shaft misalignment
  • 3/4 in bore fits standard inch-dimension shafts
  • 470 lbf dynamic load capacity handles linear motion forces
  • 600 lbf static load capacity supports stationary loads
  • Stainless steel and polymer cage resists corrosion

Linear Ball Bearing for Inch-Shaft Motion

The Dayton 2CNK8 is a closed, self-aligning linear ball bearing built for 3/4 inch shafts. Its stainless steel and polymer cage construction supports dynamic loads up to 470 lbf and static loads up to 600 lbf. It operates reliably between -4 and 176 Degrees F at speeds to 5000 in/min.

Fits 3/4 Inch Shafts with Tight Tolerance

The bearing accepts a 3/4 inch shaft with a tolerance of +/- .001 in and seats in a 1 1/4 inch housing bore. Its 1 5/8 inch overall length keeps the assembly compact. Self-alignment compensates for minor shaft deflection, reducing the need for precise mounting fixtures.

Suited for Light-Duty Linear Guides on Inch Shafts

Engineers specifying inch-series linear motion with moderate load and speed requirements will find this bearing a direct fit. It is not intended for applications exceeding 600 lbf static load, 5000 in/min travel speed, or temperatures above 176 Degrees F. Buyers needing open-type bearings for shaft support or higher dynamic capacity should look elsewhere.

  • 3/4 in bore fits standard inch-dimension shafts
  • 470 lbf dynamic load capacity handles linear motion forces
  • 600 lbf static load capacity supports stationary loads
  • Stainless steel and polymer cage resists corrosion

Questions about this item

How much continuous load can the 3/4 in bore bearing sustain before wear accelerates?

The dynamic load capacity is 470 lbf, which is the rating for sustained linear motion.

What temperature does the bearing reach during extended operation at 5000 in/min?

Maximum operating temperature is 176 Degrees F; the bearing is designed to run continuously at that limit.

What shaft tolerance must the mating shaft meet for the +/-0.001 in bore?

The shaft should be held to a matching tolerance so the installed clearance stays within the specified +/-0.001 in.
