Silver linear pillow block bearing with 0.750 inch bore and 1.875 inch length, anodized finish

Dayton

Dayton 2CNN7 Pillow Block Bearing 0.750 in Bore 1.875 in Length

SKU CH-ZN7Z-XRWYD

Linear pillow block bearing with 0.750 in bore and 1.875 in length, static load 308 lbf, dynamic load 194 lbf, operating range -4 to 176 °F

  • Linear motion with .750 in bore for precise shaft fit
  • 194 lbf dynamic load capacity handles moving forces
  • 308 lbf static load capacity supports stationary weight
  • Stainless steel and polymer cage resists corrosion
  • Operates from -4 to 176 Degrees F

Linear Pillow Block Bearing

The Dayton 2CNN7 is a linear pillow block bearing built for inch-series motion systems. It accepts a 3/4 in shaft and provides 1 7/8 in of travel length inside a single open housing. The stainless steel shell and polymer cage suit equipment that needs corrosion resistance and low-maintenance operation.

Thermals Noise and Power Draw

The bearing operates continuously from -4 °F to 176 °F without lubrication changes. Static load capacity reaches 308 lbf and dynamic load capacity is 194 lbf at a steady-state speed of 7 fps. Polymer cage construction keeps running noise low and eliminates the power draw of recirculating-ball alternatives.

Roll Pin Locking and Anodized Finish

A roll-pin locking mechanism secures the bearing to the shaft using #8 bolts, preventing axial drift without set-screw damage. The standard anodized finish adds surface hardness and chemical resistance for wash-down or outdoor environments. Buyers who need self-alignment or a closed housing should select a different series.

Questions about this item

How do I install the 0.750 in bore pillow block on a shaft and what step is often missed?

Slide the bearing onto the shaft, align the mounting holes, secure with #8 bolts, then insert the roll pin through the housing and inner race to lock rotation — skipping the roll pin is the common error.

What maintenance or replacement will the stainless steel and polymer cage bearing need over time?

The polymer cage and stainless steel races require periodic relubrication; replace the unit when clearance grows beyond tolerance or if the cage shows cracking from heat cycles between -4 and 176 °F.

At what load or speed limit does the 1.875 in long bearing show wear first during continuous operation?

Dynamic capacity is 194 lbf at 7 fps; sustained loads above that or speeds exceeding 7 fps will accelerate wear on the polymer cage before the static 308 lbf rating is reached.
