JET
Rail Roller Blocks
There is no standard off-the-shelf
direct drop-in replacement
for all open single
and twin linear ball bearing pillow
blocks. Jet Rail's open architecture and sealed roller design
allow for smooth, low resonance/noise, lightweight, high
speed linear motion.
Unlike linear ball bearings that include debris which can
lead to premature failure, Jet Rail's
open features and sealed rollers inhibit the accumulation of
debris and contaminants.
Make sure you have us quote your
linear shafting needs along with
our bearings!

LM76 JET Rail Roller Blocks
successfully endure debris such as saw
dust, lint and other contaminants
via a beryllium copper scraper
which clears debris from in front of the top
roller.

Jet Rail
Roller Blocks 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.
