Performance LubricantsRotary Unions for Corrugating or Pulp and Paper Applications

Product Information
Corrugators and pulp andpaper manufacturers canreduce downtime, extend
maintenance intervals,
and enhance productivity
with a high-performance
lubricant.
Rotary unions—also known
as rotary joints, swivels,or couplings—are used totransfer cooling water, steam, hot oil, or process fluid froma stationary source, such as a supply pipe, into a rotating
piece of equipment. Rotary unions often incorporate ballbearings to keep the motion of the rotary union smooth.
Seals are typically made from rubber and plastic, and mayneed to be changed periodically, depending upon the typeof material being transferred. Rotary unions are used insingle-facer rolls, glue applicator rolls, chill rolls, rewinders,
sheeters, paper machine calender stacks, and papermachine dryer cans.
The Challenge
The ball bearings and seals found in rotary unions usedin the corrugating and pulp and paper industries areexposed to extreme conditions that can include: steam
temperatures ranging from 204–343 °C (400–650 °F);
pressures of 100–250 psi; and speeds ranging from
300–700 rpm, to name just a few. The lubricant selectedmust be able to withstand these extreme operating
conditions and be compatible with the metals andelastomers used for the ball bearings and seals.

The Solution
Krytox™ GPL 227 lubricant provides superior lubricity,
stays in place in the presence of steam or water, performs
at temperatures up to 288 °C (550 °F)*, and does notreact with the chemicals used by corrugators and pulp
and paper manufacturers.
Krytox™ GPL 227 will not carbonize on the ball bearings,
nor break down under the pressures and speeds found inrotary unions. In addition, Krytox™ GPL 227 is compatible
with all elastomeric seal materials and all steels, stainlesssteels, and alloys typically used in rotary unions.
Key Advantages• Using Krytox™ GPL 227 lubricant, corrugators and pulp
and paper manufacturers can improve productivity by
reducing breakdowns of rotary unions and extending
intervals between re-lubrication.
• Krytox™ GPL 227 grease stays in place in the presenceof steam or water, performs at temperatures up to288 °C (550 °F), and does not react with the chemicals
used by corrugators and pulp and paper manufacturers.
• Krytox™ GPL 227 can also be used for rotary unions
used in textile equipment.

*Krytox™ GPL 227 performs at continuous operating temperatures up to 288 °C(550 °F); for higher temperatures up to 343 °C (650 °F), Krytox™ XHT BDX isrecommended.
