PT Select™ in the Grain Industry

Article Tags:
Spherical Roller Bearings
North America produces about 25 percent of the world's grain. A key to success in the grain industry is ensuring power transmission equipment is operating at optimal levels. Quality components keep equipment moving and reduce downtime. One component found in many places is the mounted spherical roller bearing. In grain production, you'll see these bearings in:
  • Bucket elevators
  • ​Screw, belt and drag conveyors
  • Mixers
  • Hammer mills
  • Dryers
  • Other equipment

Regal Rexnord's PT Select™ bearings are high quality products that will keep grain production moving.

Why PT Select™ Roller Bearings for Grain Production?

The PT Select™ line is made of readily available, off-the-shelf solutions. These bearings provide the quality and performance customers expect from Regal Rexnord. PT Select™ is available in shaft diameters from 1-7/16” to 4-7/16” and in six different housing configurations. Configurations include Type E flange and pillow block housings. Both configurations are prevalent in the grain industry.

An Upgrade from Tapered Roller Bearings

Many producers use tapered roller bearings. PT Select™ are drop-in interchanges to tapered roller bearings. Spherical roller bearings are superior to tapered roller bearings in misalignment capabilities. Additionally, they offer higher speed ratings. Switching from existing tapered roller bearings to spherical roller bearings can provide significant performance advantages for your grain operation.

Bearings That Can Stand Up to Contamination

The leading cause of bearing failure in the grain industry is contamination due to grain dust. Superior sealing capabilities are of the utmost importance. To this end, PT Select™ offers two engineered bearing seal options:
  • A standard triple lip seal option. This provides the highest level of ingress protection against contamination. The PT Select™ triple lip seal has been thoroughly tested against competitive seals. PT Select™ is proven to provide superior contamination protection. PT Select™ also has the lowest steady operating temperature. Grain dust can be explosive, so minimizing operating temperature is extremely important.

  • All-metal clearance seal. PT Select™ offers an all-metal clearance seal for high-speed applications. A recently-introduced magnetic end caps feature can be easily added to any bearing in the field.

PT Select™ has a wide variety of housings styles and shaft sizes. Combine that with excellent availability and we likely have a high-quality PT Select™ bearing ready to ship to you today.
