Introduction
Credit for long service and dependable operation of a gear drive
is often given to the engineers who designed it, or the craftsmen
who constructed it, or the sales engineer who recommended
the type and size. Ultimate credit belongs to the mechanic on
the job who worked to make the foundation rigid and level,
who accurately aligned the shafts and carefully installed the
accessories, and who made sure that the drive received
lubrication at prescribed intervals. The details of this important
job are the subject of this manual.
NAMEPLATE - Operate gear drives only at horsepower, speed
and ratio shown on nameplate and in the mounting position for
which it was ordered. Before changing any one of these, submit
complete nameplate data and new application conditions to the
Factory for correct oil level, parts and application approval.
WARNING: Consult applicable local and national safety codes
for proper guarding of rotating members. Lock out power source
and remove all external loads from drive before servicing drive or
accessories.
Warranty
Rexnord Industries, LLC (the "Company") warrants that Ultramite
gear drives (I) conform to Company's published specifications,
and (II) are free from defects of material for three years from the
date of shipment.
Company does not warrant any non-Company branded products
or components (manufacturer's warranty applies) or any defects
in, damage to, or failure of products caused by: (I) dynamic
vibrations imposed by the drive system in which such products
are installed unless the nature of such vibrations has been
defined and accepted in writing by Company as a condition of
operation; (II) failure to provide suitable installation environment;
(III) use for purposes other than those for which designed, or other
abuse or misuse; (IV) unauthorized attachments, modifications or
disassembly, or (V) mishandling during shipping.

Falk Ultramite • Installation & Maintenance Instructions
® ®
Type UJ • Sizes 302 thru 312
Type UJ
General Information
The following instructions apply to standard Falk Type UJ drives
shown above. If a drive is furnished with special features, refer to
the supplementary instructions shipped with the drive.
WELDING - Do not weld on the gear drive or accessories without
prior approval from the Factory. Welding on the drive may cause
distortion of the housing or damage to the bearings and gear
teeth. Welding without prior approval could void the warranty.
EFFECTS OF SOLAR ENERGY - If the gear drive operates in
the sun at ambient temperatures over 100°F (38°C), then special
measures should be taken to protect the drive from solar energy.
This protection can consist of a canopy over the drive or reflective
paint on the drive. If neither is possible, consult the Factory.
MOUNTING (Figure 13 and 19) - Unit sizes 308UJ and above
are furnished without oil. Refer to Table 16 for a list of typical
lubricants meeting Rexnord specifications. Fill drives to the oil
level plug. Refer to Table 11 for the approximate quantities of oil
by the drive mounting position.
Unit sizes 307UJ and below are factory filled with oil. Refer to
Figure 13 and 19 for the placement of the breather, drain and oil
level plugs based on the drive mounting position.
FOUNDATION GENERAL - To facilitate oil drainage, elevate the
gear drive foundation above the surrounding floor level. If desired,
replace the drive oil drain plug with a valve, but provide a guard to
protect the valve from accidental opening or breakage.
FOUNDATION, STEEL - When mounting gear drive on structural
steel, it is recommended that an engineered design be utilized
for a pedestal, adapter base or bed to provide sufficient rigidity,
to prevent induced loads from distorting the housing and causing
gear misalignment. In the absence of an engineered design, it is
recommended that a base plate, with thickness equal to or greater
than the thickness of the drive feet, be securely bolted to steel
supports and extend under the entire drive.
FOUNDATION, CONCRETE - If a concrete foundation is used,
allow the concrete to set firmly before bolting down the gear drive.
For the best type of mounting, grout
structural steel mounting pads into
the mounting base, as illustrated,
rather than grouting the drive
directly into the concrete.
Motors and other components mounted on motor plates
may become misaligned during shipment. ALWAYS check
alignment after installation.
