Dayton 2CNL4 Ball Bushing Bearing Open 1/2 in Bore

SKU CH-Y78S-E6Z4R

Linear ball bearing with 1/2 in bore, 7/8 in outside diameter and 1 1/4 in length, self-aligning design and 230 lbf dynamic load capacity

  • Open design simplifies shaft installation
  • Self-aligning action compensates for misalignment
  • 230 lbf dynamic load rating handles linear motion demands
  • Stainless steel and polymer cage resists corrosion
  • Operates from -4 °F to 176 °F across varied environments

Linear Motion Bearing for 1/2 Inch Shafts

This open-type linear ball bushing fits a 1/2 inch bore and 7/8 inch outside diameter. It suits linear motion systems needing self-alignment on inch-series shafts. The stainless steel and polymer cage construction operates between -4 and 176 degrees Fahrenheit. It is built for machinery and automation tasks requiring smooth travel.

Dynamic Load 230 lbf and 5000 in/min Speed Limit

The bearing handles a dynamic load capacity of 230 lbf and a static capacity of 255 lbf. Steady-state speed reaches 5000 inches per minute under normal conditions. Inside diameter tolerance is held to +/- 0.001 inch for precise fit. Applications exceeding these load or speed ratings will need a larger or different bearing series.

Self-Aligning Design With 0.34 Inch Slot

The self-aligning feature compensates for minor shaft misalignment without extra components. An open slot width of 0.34 inch allows clearance for shaft support rails or mounting hardware. No seals are included, so the unit suits clean environments or setups with external protection. Lubrication access is direct through the open ball tracks.

Questions about this item

Will the 1/2 in bore match the 1/2 in shaft I already use?

Yes, the 1/2 in inside diameter with a tolerance of +/- 0.001 in fits a standard 1/2 in shaft.

How can I confirm the bearing is running correctly after installation?

The bearing should move smoothly along the shaft without binding and stay within the -4 to 176 °F operating range.

Does the open ball bushing come with seals or lubricant, or must I buy them separately?

The open design has no integral seals; lubricant and any external seals are purchased separately.
