The new FYH original solid base pillow block housings

seat better and produce a more stable mounting configuration that significantly reduces vibration.
The support ribs have been eliminated to make more room for mounting bolts and washers, yet these housings are more than 30% stronger than before while also reducing housing weight.

The new FloBack seal incorporates a number of features which translate to
longer bearing life over competitive designs. It consists of a double-lip
seal which is stamped into place in the outer ring of the bearing to reduce
the possibility of being pushed out from over-lubrication. The first seal
makes contact with the inside of the slinger which provides the first line
of defense against contamination. The next seal makes contact with the inner
ring to provide another level of contamination resistance. An additional
level of protection exists in the extra non-contact inward facing lip which
allows grease to flow back towards the balls and raceways during operation
thereby improving lubrication performance and extending bearing life. The
new FYH FloBack seal design allows for excellent bearing outer ring
roundness which maintains the FYH "J" fitting tolerance with all housings
and mounting configurations.
Allowable rotating speed is same as the previous seal design.

New FYH Lithium Bearing Grease is a perfect match for the specific design considerations of FYH Bearings, and it has been formulated to handle a wide range of operating conditions. FYH Lithium Bearing Grease can be mixed with other brands of FYH grease including Gold 3A lithium soap grease as it will improve performance, corrosion resistance, loading capability, and promote longer bearing life.

FYH Lithium Bearing Grease is an NLGI 2 lithium complex grease that provides substantial improvements over general purpose lithium soap based lubricants. It functions extremely well under a variety of highly demanding operating conditions including wide temperature ranges, variable speeds, water contamination, vibration, heavy loads, and shock loads.
In addition to its high quality base oils, it contains oxidation inhibitors and extreme pressure additives which are both crucial to maintaining a high degree of protection where high loading and moisture and chemicals are present.
FYH Lithium Bearing Grease exhibits excellent water wash-out resistance, and extensive testing has proven this lubricant to be successful where such challenging conditions exist.
Due to its compatibility with the existing formula, not only can the new and improved formulation enhance operating characteristics, it can also extend the useful life of units that are currently in operation.

The FYH LUBE EZ an electrochemical automatic single point lubricator, operates based on the proven technology of electrochemical reaction which generates inert Nitrogen (N2) gas through the systematic use of an electrolyte and electrical energy. FYH LUBE EZ can be programed easily with five different preset dispensing rates of 1, 3, 6, 9, and 12 months and is filled with FYH Lithium Bearing Grease. FYH LUBE EZ is not only great match with FYH Pillow Block Units, but also offers a cost effective solution for a wide variety of industrial applications.
In addition, the intuituive design of FYH LUBE EZ ensures both error-free operation and safe use.
