Timken® Fafnir® Housed Units

Timken®
Fafnir ®
Housed
Units
Designed to maximize performance,
Timken® Fafnir® ball bearing housed
units combine the bearing, housing,
seal and locking system into one device
for easy installation and operation.
Timken’s robust pillow block gives you
the same features you’ve come to rely
on, now in a stronger housing.
Similar to other housed units, this
product provides shaft support for
radial, thrust and combination loads to
help reduce friction in a wide variety of
industrial applications. The product’s
rugged design is its biggest advantage.
The robust block outperforms standard
housed units by operating in the
most demanding applications and
challenging environments.
These pillow blocks are available with
two types of locking mechanisms:
eccentric locking collar and set screw
with shaft guarding technology. The
patented eccentric locking collar selftightens to the shaft without shaft
damage. The set screw insert also
provides shaft protection and prolonged
shaft life with its newest enhancement
– shaft guarding technology. Housed
units equipped with this innovation help
eliminate the problems encountered
from relative motion typically associated
with set screw products – nicks, raised
metal or permanent shaft damage.
Robust Pillow Block Features:
Superior Finish. Black powder-coated
epoxy finish for corrosion protection and
superior performance.
Base-to-Center Line Height
Indicator. To help identify correct base-to-center line block.
HB=high base; LB=low base.
Set Screw Access. Allows for
bearing set screw access (during
installation or removal) regardless of
pillow block orientation.
Solid, Flat Feet. Increased strength and no recess corner
stress points. Virtually eliminates deformation of mounting surface. Prevents accumulation of ambient material under the feet.
Heavier, Stronger Block. Wider along
shaft axis and 30 percent heavier for
better bearing seat strength. Three times
stronger in both upright and upsidedown mounting positions.
Easy Access to Mounting
Bolts. Uses same mounting
hardware as current block
design.
Timken® Fafnir ® Housed Units
with Shaft Guarding Technology
Timken has introduced one of the
easiest-to-install housed units available.
It features a conventional setscrew, but
provides shaft protection and prolongs
the life of the shaft – no nicks, raised
metal or permanent shaft damage. You’ll
find Timken’s patented shaft guarding
technology where production uptime
is critical and shaft replacement is
expensive.
Where traditional setscrew products rely
on the setscrews to dig into the shaft to
maintain grip, Timken’s shaft guarding
technology transfers the pressure
of the setscrews through a stainless
steel, hardened band. This absorbs the
problems encountered from relative
motion typically associated with setscrew
product. The stainless band will not
corrode to the shaft.
Shaft guarding technology exceeds
gripping application requirements,
maintains dimensional integrity and
reduces fretting corrosion. It locks to the
shaft like a traditional setscrew, but with
new benefits:
Faster and easier installation
and removal
Reduces number of shaft replacements

Available with Timken thin-dense
chrome option
Seal options include three-piece “R”
seal for normal- to high-contamination
environments and “L” seal for higher
speeds and temperatures

Features
Combines
Two setscrews and nylon patch at
90-degree separation provide
maximum holding capability with
minimal distortion
Implements
Groove running beneath the
setscrews in inner ring bore
to keep the band in place
Hardened stainless steel band
protects the shaft from damage
Longer inner ring along the shaft
(ABMA-compliant) improves shaft
support and reduces bearing
misalignment
Timken offers a complete line of
application-specific, custom-formulated
lubricants that help bearings and
components operate efficiently
in industrial environments. Hightemperature, anti-wear and waterresistant additives offer superior
protection in the harshest conditions.
You can turn to Timken for all the friction
management products you need to
extend life, boost productivity and
reduce downtime.
