The lining is woven in one piece on massive looms, under
proper tension to insure a tightly woven superior quality product. Impregnated by
vacuum process with high heat resisting compound, cured under tremendous heat
and pressure, and specially treated, Lewis Lining is impervious to water, oil
and grease. Abrasive-free fiber, wire insertion with infusible resins, tight
weave, and pressure curing eliminate flange scoring tenden-cies and assure
longer life!
Roll Lining is available in all thicknesses and widths for neutral
brakes, special size drilling units and cable tool spudders, and miscellaneous
units not shown in the catalog.
LEWIS BRAKE BLOCKS are formed to the precise arc of
the flanges, are easy to install, and can be counted on to conform to the
flanges during a long life of dependable performance. They are recommended for
deepest well digging under all conditions. New Drawworks – Our engineering
department keeps abreast of the latest engineering developments in draw-works.
We are in a position to furnish the proper size brake
blocks for newest type drilling rigs. Lewis Brake Blocks are drilled to fit each
individual drawworks and are also available undrilled. Unless the band is known
to have a standard or A.P.I. hole spacing, we recommend ordering undrilled
blocks. HOLE PLUGS can be furnished, if desired. These plugs
provide 100% wearing surface and minimize the collecting of dirt and abrasive
particles.
Built-in wiper blocks are available
optionally. These latest engineering advancement make for longest life of brake blocks and drum flanges. Frictional
torque is more regular, evenly distributed around drum flanges, and fewer hot
spots and strains develop. Wiper blocks provide a non-abrasive scouring and polishing
action on brake flanges for smoother, better condition.
