Jet Rail
Bearings are direct drop-in replacements for all inch
linear ball bushing open pillow block assemblies that run on supported shafting.
They
provide low friction, quiet/smooth operation and do well in contaminated environments.
JET RAIL Roller Bearings provide three genuinely novel accessories:
1. Scrapers, 2. Floating Bushings, 3. Linear Carriage Locks. This bearing is
great for shaft misalignment,severe shaft deflection and can even travel a radius ( 6" - 60"
depending on the size of the pillow block ). There is no standard off-the-shelf linear product in this form factor that
offers you this many advantages - none. JET AWAY! Shipping in 2- 4
business days - Always!
