NSK responds to MRO demand by offering larger size NSK HPS Series Spherical Roller Bearings

Industrial production increased 0.6 percent in June primarily related to vehicle manufacturing and mining sectors experiencing small increases in production.  June was forecasted to only achieve 0.4 percent increase; therefore, economists are hopeful that second half of 2016 will experience continued, gradual growth in production as long as domestic demand for manufacturing stays consistent.  – Wall Street Journal (07/15/16) Sussman, Anna L.

To continue to grow business in these economic conditions, NSK has dedicated their efforts to MRO (maintenance, repair and operation) business for the aftermarket.  At NSK, we stand by our efforts to provide superior products and after-sales service backed by brand-recognized quality, reliability and performance.




In 2004, NSK introduced the HPS Series to the aftermarket with small size spherical roller bearings.  Over the last 12 years, NSK has expanded its product offering to include angular contact ball bearings, deep groove ball bearings, cylindrical roller bearings and other bearing types ranging in a maximum size of 400 mm.  Last month NSK announced that the HPS Series Spherical Roller Bearing size range would be expanded to 400-600 mm size range.

Spherical roller bearings are designed for high load capacity, high speeds and suitable for a wide range of applications.  The HPS Series can withstand working in temperatures up to 200°C, operate at 20% higher speeds and achieve two times more bearing life compared to conventional bearings.

NSK Spherical Roller Bearings Success

A cement mill was using a competing spherical roller bearing in their hammer mill application.  Contamination was entering the bearing block, which ultimately led to bearing failure.  Due to contamination, the bearing needed replaced every 4 months.  As a result, the mill was experiencing excessive change outs, lost production and increased maintenance cost.

NSK recommended changing from a standard labyrinth LER seal to a Taconite Seal TER155OS SAF Pillow Block and HPS Spherical Roller Bearing.  This solution increased bearing performance from merely 4 months to over 2 years and saved the cement mill more than $200,000 annually!

NSK increased Bearing Performance and saved Cement Manufacturer more than $200,000!

Cement SAF Housing

Contamination is a leading cause of bearing failure.  Heavy industrial applications are susceptible to even higher levels of contamination compared to others.  In order to combat against contamination and improve bearing performance, NSK applied AIP to suggest product changes that resulted in over $200,000 in savings.

A hammer mill application was using a competitor’s SAF pillow block and bearing that was failing after only 4 months of operation.  Upon inspection, NSK determined that debris had entered the block.  Excessive change-outs were causing significant financial strain in lost production and maintenance cost.

NSK proposed changing from a standard labyrinth LER seal to a NSK Spherical Roller Bearing inside a SAF Pillow Block (SAF22538) with Taconite Seal TER155OS.


TER-OS Taconite Seal


The TER-OS taconite seals are designed to prevent entry of contaminants in severe service conditions.  Each seal is equipped with a shaft contact spring-loaded oil seal, grease-charged channel, felt shaft seal and O-ring seal in the housing labyrinth to form an impenetrable barrier and provide a tight, yet flexible fit.  The use of this seal protected the spherical roller bearing within the SAF housing to achieve longer life.  The NSK solution provided over 2 years of service life compared to 4 months service life from competitor’s product.

Cost Savings Breakdown:

Competitor Product

Bearing Installation: 5 installs @ $2,981  = $14,905

Maintenance Cost: 40 hrs x 2 personnel @ $150 per hour = $12,000

Lost Production: 500 tons @ $90/ton x 5 failures = $225,000

Total:  $251,905

NSK Solution

Bearing Installation: 1 install @ $2,981  = $2,981

Maintenance Cost: 8 hours x 2 personnel @ 150 per hour  = $2,400

Lost Production: 500 tons @ $90/ton x 1 install  = $45,000

Total:   $50,381

Total Cost Savings:  $201, 524

NSK’s NH Series Linear Guide Increases Throughput for Automotive Supplier

An automotive supplier, who produces aluminum transmission housings, was experiencing issues with its transmission leak testing equipment.  The facility was experiencing a 20% failure rate once its transmission housing reached the test phase.


Aluminum Transmission Housing

When a failure occurred, a new test had to be administered leading to reduced throughput.

It was determined that the bushing system used to transport the transmission housing into the test area was the leading cause of the issue.  The bushing system didn’t deliver precise movement or protect transmission housing against contamination.

NSK proposed that the installation of NH Series Stainless Steel Linear Guides with K1™ Lubrication Units be used in replacement of the bushing system.

NH Series Linear Guides are known for offering maximum precision, high load ratings and smooth linear motion.  This product line is used for a wide variety of applications and has proven success in medical technology, semiconductor, machine tool and automotive industries.

Adding K1™ Lubrication Units provides long-term maintenance-free operation by allowing fresh, continuous oil to flow onto rail during operation.  This innovative solution is ideal for environments where grease replenishment is undesirable or in areas where grease is easily washed away.

New Linear Guides

NH Series Linear Guides with K1 Lubrication Unit


Once NH Series Stainless Steel Linear Guides with K1™ were installed in the facility, the failure rate was reduced to 6% which significantly improved throughput and decreased cost per piece produced.

Cost Savings Breakdown:

Bushing Method

Production Cost: 810 parts per month: $75,632 x 12 months = $907,584

NSK Solution

Production Cost: 940 parts per month: $64,273 x 12 months = $771,276

Total Annual Savings

Total Cost of Bushing Method minus Total Cost of NSK Solution

= $136,308 total cost savings!

Best Practices for Storage, Removal and Transportation of Bearings

Proper handling and storage of bearings is important to assure the best in bearing performance. Improper storage and handling can damage a bearing and/or create unnecessary contamination which can lead to bearing failures.


To ensure optimal bearing performance, bearings should always be stored flat, indoors, in low humidity and in original packaging.

NSK recommends that the Bearing Storage Area be:

  1. Clean.
  2. Dry.
  3. Kept at a consistent temperature.
  4. Kept away from vents or windows that might alternate temperature.
  5. Humidity less than 75%.
  6. Free from vibration.

If the bearing has been in use and removed from equipment, refer to these guidelines for storage after removal;

  1. Coat with LPS3 (or other corrosion inhibiting oil).
  2. Tightly wrap the bearing with VCI wrapping paper.NSK Bearing
  3. Lay bearings flat, not on end.
  4. For large bearings, lay flat on a wooden pallet.
  5. For smaller bearings, place flat in cardboard boxes.
  6. Always remember to follow 6 storage criteria from list above.


When a bearing needs to be removed from equipment, follow the guidelines below:

  1. Flush the bearing grease before final shutdown to remove as many contaminants as possible.
  2. Perform a visual inspection of the housing, neck and bearing before cleaning.
  3. Thoroughly clean bearing with a petroleum based solvent.
  4. Immediately apply rust preventative oil to avoid corrosion after cleaning.
  5. For spherical bearings, oil should be applied while rotating the inner ring to reduce potential scratching.
  6. Align ring and support all rolling elements.
  7. Handle with care.


Follow these guidelines to transport bearing only:

  1. Clean the bearing.
  2. Coat with LPS3 (or other corrosion inhibiting oil).
  3. Place O-ring material next to the sides of the rolling elements to avoid false brinelling.
  4. Tightly wrap bearing with VCI wrapping paper.
  5. Cover with heavy plastic bag or wrap with tire wrapping.
  6. Lay flat on a wooden pallet base and secure with blocks to prevent movement.
  7. Strap everything down to pallet.

If you need to transport assembled bearing in its housing, we recommended a few modifications for safer transport:

  1. Flush housing with new grease or oil.
  2. Rotate shaft to spread the lubricant.
  3. Secure the housing to the transport surface using the housing mounting flanges if possible.
  4. Secure the rolls with straps to the transport surfaces to reduce possibility of false brinelling.
  5. Cover the assembly with tarps and strap everything down.

Following these guidelines will help reduce bearing damage during storage and transportation.
