SEALMASTER BEARINGS LOWER MAINTENANCE COSTS, PROVIDE LONGER PRODUCT LIFE

By Woody Schmetzer

When choosing the right bearing, cheaper is not always better—or even cost effective. A less expensive bearing typically means lower quality, additional bearing change outs and more bearing purchases. Even though the bearing is less expensive on paper, over time the costs can add up.

For example, OTP recently helped a customer with two bottling facilities lower its maintenance costs and improve its operations by choosing a product line that stood above the competition and was a great fit for our customer’s needs. Each of the customer’s plants experienced premature bearing failures and went through many pillow and flange block bearings, which we supplied to them for years. It reached a point where we needed to do something different to improve the bearings’ performance.

After analyzing our customer’s operations and unique needs, OTP technicians selected Sealmaster bearings. The Sealmaster bearing chosen for our customer handles loads better and provides enhanced lubrication, which results in longer bearing life. The Sealmaster bearing provides superior features:

  • Wider inner and outer races
  • Felt seal instead of rubber lip
  • Land riding metal ball retainer
  • Zone hardened inner race
  • Locking pin that allows grease to go directly into the insert bearing

Overall, switching our customer to Sealmaster bearings meant less maintenance and downtime from changing out worn bearings. Three years later, the Sealmaster bearings are still running strong inside our customer’s facilities.

EXTERNAL INFLUENCES ON LIQUID VISCOSITY AND YOUR SPRAY SYSTEM

By Nathan Webb

How often does an operator come to you reporting solvent popping, poor material coverage or orange peeling on your company’s product? These are common problems and can lower production efficiencies, increasing rejects and reworked product on your production lines. One important factor to consider when troubleshooting your spray system is the changes in viscosity due to the varying temperatures of the material being applied.

Change in liquid viscosity primarily affects your spray patterns and the application capacities of the product. Many operators will combat this by changing air or fluid pressures on their spray equipment to get the desired results, but this can negatively impact your system’s efficiency. Liquids with a high viscosity require a higher minimum pressure to begin spray pattern formation, while lower viscosities require less. The result is inconsistent spray patterns and poor coverage of product.

There are several areas to consider when your viscosities are being influenced by outside elements:

  • Spray booth ventilation system function – Check for proper airflow through your spray booth. Verify all equipment and dampers are functioning properly. Is humidity a factor?
  • Temperature of the production area Do the occurrences appear on specific shifts only? Are seasonal changes influencing these areas on your line?
  • Distance from material reservoir to spray equipment Loss of heat during transfer is common and easily remedied. Relocation of reservoirs, in-line heaters or jacketed lines should be considered to maintain a consistent fluid temperature if pipe run is significant.
  • Proper storage and placement of product – The storage and staging of material before it’s used in production can adversely affect viscosity if the containers are not handled correctly. The average time required for a 55 gallon drum of material to return to ambient temperature is TWO days if not stored in an environmentally controlled area.

To assure consistent viscosity of the liquids, one consideration is to maintain a consistent temperature of the material. A KREMLIN AD60 heater is an excellent way to maintain a constant temperature in your fluid lines. By maintaining a lower viscosity, atomization pressures can be reduced, resulting in higher transfer efficiencies and a more consistent finish.
