Dayton 2CNK4 Ball Bushing Bearing Closed 1 in Bore

1-inch bore linear bearing

The Dayton 2CNK4 is a closed-type linear ball bushing with a 1 inch inside diameter and 1 5/8 inch outside diameter. Its stainless-steel and polymer cage construction suits new machinery builds and replacement jobs where inch-series dimensions are required. The bearing is not self-aligning, so the mounting must provide accurate alignment. It operates between -4 and 176 degrees Fahrenheit.

220 lbf dynamic and 353 lbf static load

Dynamic capacity of 220 lbf gives reliable performance for moderate linear motion at steady speeds up to 5000 inches per minute. Static capacity of 353 lbf provides headroom for stationary loads and momentary peaks. Inside-diameter tolerance of +/- 0.001 inch ensures consistent fit on precision shafts. The closed design retains lubrication and excludes contaminants in clean environments.

Replaces worn inch-series bushings

This unit upgrades or restores linear guides that have developed play or binding due to wear. The jump is worth it when existing bearings no longer hold the +/- 0.001 inch tolerance or when operating temperatures approach the 176 degree Fahrenheit limit. It is not for applications requiring self-alignment or metric shaft diameters.
