BURLINGTON — Recently, a Texas-based company and a major customer for Thordon Bearings, had a last call requirement to replace the bearings in a cooling water pump for a thermal power plant in Mexico. The lead time from another supplier to replace the original rubber bearings exceeded the company’s contractual delivery schedule. Thordon Bearings was able to provide the four fully finished vertical pump bearings within three days to meet their delivery deadline.

Arturo Selvas, Sales Director with Rotary Parts, Thordon Bearings’ Mexico-based distributor, said: “We have created an excellent rapport with this company over the past several years, providing frequent service support. Thordon’s technology was highly recommended for this cooling water pump.”

Thordon Bearings’ Strategic Account Manager – Vertical Pumps, Keith Brand, elucidated the story: “An order was placed on July 3rd, 2020. Two days later Rotary Parts received the bearings and set about the machining and finishing process. The customer received all four SXL bearings within the very tight deadline and was able to have the critically important cooling water pumps back in operation on time.”

The SXL grade, the market leader in grease-free vertical pump bearings, is manufactured from Thordon’s proprietary elastomeric polymer and is the industry’s preferred choice for pump applications requiring a dry start. With a lower dry coefficient of friction typically 0.10 – 0.20, the SXL bearing has a working pressure to 10 MPa (1450 psi) and is resistant to abrasion, shock loading and vibration.

“Wear life is the biggest advantage to using Thordon non-metallic materials, but also offers ease of use. We have a bearing sizing calculation program that makes it easy to determine correct sizing, and they are easy to machine. There is no harmful dust when machining Thordon polymers which is a big advantage over phenolic bearings. And then when it comes to installation, we can freeze fit, press fit or bond fit, so there are other options there too,” said Axel Swanson, Business Development Manager, Thordon Bearings.

Thordon designs and manufactures a line of product lubricated vertical pump bearings for applications across a number of industrial sectors.
