SPECIFICATIONS
Recommended Worm Gear Oil:
We have published the following specifi cations to help you determine which lubricant is best suited to your
application. For simplicity, Braden has listed readily available products in each temperature range which has
been tested and found to meet our specifi cations. This is not to say that other lubricant brands would not
perform equally as well.
If the following lubricant brands are not available in your area, make certain your lubricant vendor supplies
you with oil that is equivalent to those products listed below.

Do not use aftermarket additives in worm gear oil. Some additives may contain substances which could
cause glazing of brake discs or impede the fi rm locking action in the brake rotor assembly. Both symptoms
could reduce load control which may result in property damage, severe personal injury or death.
Brand recommendations in tier C climate range:
MOBIL Mobilgear 600xp 460
SHELL Omala 460
CHEVRON Gear Compounds EP460
TEXACO Meropa 460
NOTE: For cold weather applications, synthetic versions of the recommended oils may be used. Please note
that use of synthetic oils in worm gear winches requires the gear set to be “broken in” with mineral oil before
using the synthetic oil. Failure to break in the gear set with mineral oil will cause slippage between the gears
which could allow the load to slip or fall.
