SKF - Spherical Plain Bearings and Rod Ends

Rod ends requiring
maintenance
Steel/steel and steel/bronze rod ends require
lubrication. To facilitate this:

• All SKF steel/steel rod ends, with the exception
of small-sized E and ESA design rod ends,
can be relubricated via a lubrication hole or
grease fitting in the rod end housing as well
as via the pin and the inner ring († fig. 5).
• All SKF steel/bronze rod ends can be
relubricated via a lubrication hole or grease
fitting in the rod end housing († fig. 6).
The general recommendations for steel/steel
radial spherical plain bearings also apply to
steel/steel rod ends as well as steel/bronze rod
ends.
For steel/bronze rod ends in the SIKAC .. M and
SAKAC .. M series, SKF recommends SKF LGMT 3
grease († table 1 on page 87). Lithium based
greases with a normal consistency without solid
lubricant additives can also be used.

Maintenance-free rod ends
Maintenance-free, self-lubricating rod ends are
designed to be used as dry sliding bearings and
must not be lubricated. Consequently, these rod
ends do not have a relubrication facility in their
housings.
Steel/PTFE FRP rod ends are an exception.
They can be used without additional lubricant,
but their service life can be extended appreciably
if they are lubricated prior to use.
CAUTION: Depending on their design, SKF rod
ends are either completely or partially coated
with an oily preservative or filled with grease.
Avoid skin contact as these substances may
cause skin irritation or an allergic reaction.
