Four point contact bearings - VLA200744-N that meet the rigorous requirements of the industry.
At the core of every mining operation is a complex array of mining machines, from compact, yet powerful, continuous miners in underground mining to the larger-than-life draglines found in surface mining. Even with some of today’s most complex equipment, mining is still, at its core, a fairly simple process that can be broken down into three basic components: mining, transport and removal.
Four point contact bearings - VLA200744-N. With our experience in the mining, construction, agriculture, and heavy-duty truck markets, we have the products capable of performing in the dirty, harsh environments of mines and exceeding reliability and life requirements.
One of the toughest industrial equipment applications for Four point contact bearings - VLA200744-N is vibrating screens or shaker screens. Distributor Bearing Wholesalers Inc has developed a special line of spherical roller bearings specifically designed for the severe applications found in shaker screens and all vibrating equipment. Distributor Bearing Wholesalers Inc Shaker Screen Sphericals have distinct features that make them ideal

We offer Four point contact bearings - VLA200744-N under the Distributor Bearing Wholesalers Inc. Most bearings feature case-carburized components. Rings and rollers are made from case-hardened alloy steel of “Bearing Quality” to provide superior fatigue life and reliability. Precise control of heat treatment, dimensions, and surface finish of the components further contribute to reliable bearing performance. So whether you’re looking for an American-made, case-carburized inch series cylindrical, or a metric series through-hardened variety, Four point contact bearings - VLA200744-N has you covered with a proper fit to your application. Premium steels and heat treatments are also available for applications requiring extended life and high reliability.
AS HEAT TREATMENT
Four point contact bearings - VLA200744-N’s Austenite Strengthening process (AS) is a special heat treatment applied to the rolling elements. By chemically altering the surface chemistry of the roller, Four point contact bearings - VLA200744-N is able to create a thin layer of retained Austenite that results in compressive stresses that increase bearing life. AS Treatment alone results in a material life multiplier of 1.5. When used in conjunction with TMB, that life multiplier increases to 3.6.
