NSK Bearings for the Paper Industry

The high quality and toughness of NSK bearings reduce maintenance costs in the papermaking industry.

Papermaking machine bearings operating under high temperature conditions are vulnerable to problems such as fracturing of the inner ring, which can result in work stoppages. NSK bearings, with their long service life, superior resistance to inner ring fractures, outstanding hardness, and excellent dimensional stability under high temperatures, produce solutions or a host of paper mill applications and operating environments.

TL Series Spherical Roller Bearings

Provide superior resistance to inner ring fractures, which is ideal for papermaking machinery operating under high-temperature conditions. The tough, long-life, TL series of bearings help boost productivity and lower costs.

Adopting NSK’s proprietary steel grade (new specification bearing material) and a special case hardening and heat treatment process, resistance against inner ring fracturing has been dramatically improved. Raceway surface hardness has been increased for longer life performance. Dimensional stability under high temperature (200°C) operating conditions.

NSKHPS Spherical Roller Bearings

Next-generation standard bearings utilizing innovative materials and technologies benefit from NSK’s experience and expertise to deliver longer life and higher limiting speed.

Molded-Oil™ Bearings

Molded-Oil bearings are lubricated with oil-impregnated solid material, which is contained within the bearing. Oil slowly seeping from this solid lubricant material provides ample lubrication to the bearing for extended periods.

  • Designed to prevent water and other liquids from washing out the lubricating oil while preventing dust and other contaminants from getting inside the bearing.
  • Low-torque performance, which is achieved by packing the bearing with oil-impregnated solid material after bearing surfaces have undergone a special surface treatment.
  • Protect the working environment by eliminating stray oil mist or leakage.
  • High-speed capability enabled through optimal composition of the solid lubricant material and methods used for the molding process.

EM Series Cylindrical Roller Bearings

Bearings with integrated machined cages offer enhanced performance by combining the advantages of the conventional M series bearings and high-load EMA1 series.

Triple Ring Bearings

A uniquely structured, highly precise, long life, anti-creep bearing that also facilitates easy of handling and mounting.

  • High load capacity design.
  • Vacuum melted, carburized steel for long life performance.
  • High precision.
  • Optimal inner ring design for improved lubrication.
  • Lubrication hole and groove provided on inner and outer rings.

CA Series Spherical Roller Bearings

The CA series features a machined cage; offers superior radial load capacity and alignment; and provides high load capacity and excellent strength. This product lineup includes high running accuracy to ISO tolerance class 5.
