Shaft Sealing

The PackRyt® Sealing System is a unique stuffing box sealing arrangement that incorporates a bearing and flush channel system together. This replaces outdated packing/lantern ring/packing configurations. It can also replace hard-to-maintain mechanical seals. Our system brings shafts into concentricity and keeps them there, significantly increasing sealing reliability.

Don't be fooled by copy-cats with inferior designs and materials.

PackRyt BLR bearing


  • Machined to close-clearance, the bearing stabilizes the shaft and prevents movement
  • Cavitation caused deflection is minimized
  • Results in minimal friction to sleeve/shaft
  • Minimal clearance sharply throttles solids, which allows the low-flush to keep them out of the shaft area
  • Flush use reduction averages over 65%
  • Flush flow remains constant
  • Automatically positions flush channel correctly, lantern ring cannot move past flush inlet
  • Little, or in some cases, no leakage from gland follower to atmosphere
  • Eliminates need to constantly adjust packing
  • As few as two rings of packing required
  • High performance, ultra pure heat conductive sealing rings can virtually eliminate sleeve/shaft wear


  • Tremendous compressive strength
  • Impervious to most chemicals.
  • Virtually no dimensional growth up to 260ºC
  • Split, pinned, drilled and tapped for easy installation and removal.
  • Available as split bearing without lantern ring groove (Product Name: BRG).

The root cause of most rotating equipment
failure is shaft movement

SealRyt's patented technology has proven it's ability to seal, support shafts, and increase reliability.

Shaft movement in the stuffing box is unrestrained and is the root cause of equipment and sealing failures.

The PackRyt Bearing System virtually eliminates shaft movement which increases both equipment and sealing reliability.

Case Studies

Dissolving Tank Agitators

A PackRyt® Sealing System was installed on 4 hard coated shaft tank agitator units and they have been running trouble free for over 2 years.

Previously these units had shaft change outs every year at a cost of approximately $80,000.00.

Stock Pumps

A PackRyt® Sealing System was installed on a 3175 stock pump having extreme leakage and maintenance issues. The PackRyt® eliminated the problems. All pumps and agitators on the paper machine and the pulp dryer are now being considered for change out.

Fiber Line Equipment

A chip chute pump was being re-packed every 2 months and now with the PackRyt® Sealing System installed it has one annual packing change. The bearing has had a life span of over 5 years.

We have compiled a list of life span results from different equipment the PackRyt BLR has been installed.
