Dayton 2CNL8 Pillow Block .500 In Bore 3.500 In L Collectible

Specifications and Build Fit

This linear pillow block bearing uses an inch measurement system with a .500 in bore and 3.500 in overall length. The twin closed housing is made from stainless steel with a polymer cage and standard anodized finish. It mounts with #6 bolts using a retaining ring locking type and is not self-aligning. Dynamic load capacity reaches 230 lbf and static capacity 352 lbf at a steady state speed of 7 fps.

Operating Range and Integration

The unit operates between -4 Degrees F and 176 Degrees F, suiting indoor machinery and light industrial environments. Its fixed alignment means the shaft and mounting surface must be accurately prepared to avoid binding. The compact length frees space in tight linear motion assemblies while the anodized finish resists corrosion in humid conditions.

Upgrade Context

This bearing replaces worn inch-series pillow blocks with the same bore and bolt pattern where self-alignment is not required. The jump is worthwhile when the original unit has exceeded its load rating or shows cage wear, and the application stays within the 230 lbf dynamic limit. It does not suit designs needing angular compensation or metric mounting.
