Thordon bearings can replace greased bearings in log grappler

Operation without grease, long wear life, low friction, high abrasion resistance, and application engineering technical support provide industrial customers with bearing solutions that meet, or exceed, specifications. ThorPlas-Blue thermoplastic bearings can replace greased bronze bearings offering increased strength and rigidity allowing working pressures in an interference fit bearing up to 45MPa (6,527 psi).  Elastomeric polymer grades, SXL, Composite, HPSXL and XL outperform metallic and less resilient, non-metallic bearings under abrasive and high shock loading conditions; Thordon bearings will not “pound out” or split. Many engineers also report a significant reduction in noise levels after installing Thordon bearings. Please see the Thordon Material Selection Guide for Various Application Parameters here for selecting the best Thordon grade given the operating pressures and medium.

Typical Thordon industrial bearing and wear component applications are found in pumps, hydro-turbines, sewage and wastewater treatment, pulp & paper, forest industry, sugar cane, mining, automotive manufacturing, injection molding presses, the steel industry and many others. Products include grapple bearings, pump bearings, lock and dam gate bushings, screw conveyor bearings, wire rope sheaves, wear components and hydraulic/pneumatic Thorseals.

ThorPlas-White

ThorPlas-White is the newest polymer in the Thordon bearing family, specifically developed to operate as a drinking water system component used in the treatment and distribution of potable water, and as a material used in the construction of food equipment. It has been listed by the NSF International Certification for NSF/ANSI 61 Drinking Water System Components and NSF/ANSI 51 Food Equipment Materials, and has also achieved WRAS (Water Regulations Advisory Scheme) material approval.  ThorPlas-White is an engineered thermoplastic alloy that offers high strength, low friction and dry start-up capability.

ThorPlas-White offers the following benefits:

  • Low friction operation
  • Long bearing wear life
  • Good dry run capability due to built-in lubricants
  • Easy to machine – no nuisance dust
  • Easy to install
  • High resistance to heat, corrosion and abrasion

Typical Applications:

ThorPlas-White is a great replacement for greased bronze and roller bearings.  It can be used in a variety of food equipment, drinking and potable water bearing applications, where NSF 51 or NSF 61 certification is required:

  • Water treatment plants
  • Food processing plants that require water
  • Mixer/ agitator bearings
  • Pumps: well and river, submersible, water intake
  • Bottle filling equipment and valve bearings
  • Water wheels and Irrigation systems
  • Conveyor bearings, hanger bearings
  • Milling equipment, labeling equipment
  • Scrapers

Engineered Molded Elastomers

Thorseal

Thorseal is a molded, polymer U-packing uniquely designed for hydraulic applications. Thorseal lip seals are formulated from a tough, high strength polymer impregnated with internal lubricants available in standard and custom sizes up to 100" (2.5m). Thorseals are designed to suit either piston or gland mounted applications operating in a temperature range of -50°C to 90°C (-60°F to
195°F).

  • high performance elastomer hydraulic lip (cup) seal Thordon thorseals for hydraulic applications
  • highly abrasion resistant - also used as a seal to exclude abrasives from limited motion bearings
  • suitable for pressures from 0 to 100.0 MPa (0 - 15,000 psi)
  • recommended for reciprocating linear or limited motion rotary applications
  • very tough - cut and tear resistant
  • low friction - self-lubricating
  • available in single lip or stacked ThorPak ("chevron" style)
