Hub Units with Patented Seals with Full Warranties

Strength and Endurance:

Our integral design for agricultural applications are easy to install and replace. Forged with high quality steel and a unique heat-treatment process yields a service life fitting of any application. Our agri hub units are lubricated for the entire life cycle of the unit and are maintenance-free. Not only do our patented seals prevent debris on average better than out competitors, but the risk of grease leakage is greatly reduced.

Strong and simple design, customizable components, and on-the-shelf availability make WD agri hub units a powerful and economical option for many applications.

Combined Bearings: Components and Uses

Most simply, a combined bearing is composed of three distinct components:

  1. Radial Bearing : A profiled outer ring used for guided rolling contact along a steel rail or channel
  2. Axial Bearing : This integrated roller guides and maintains the position of the bearing along its track while offering axial load resistance.
  3. Stub Axle (Shaft) : This central shaft stabilizes the bearing and offers simple relubrication and assembly.

Strong and simple design, customizable profiles, and easily exchangeable components make combined bearings a robust and economical option for many applications.

These high-load combined bearings offer the flexibility in handling axial and radial loads in one or both directions simultaneously. With so many rolling elements, the carrying capacity of combined bearings are some of the highest available in any bearing type.

In applications where space is tight, combined bearings offer a lower cross-section to maximize the available space. Combined bearings from WD Bearing Group have an optimized (customizable) profile and can be welded within the mounting plate to eliminate the need to dismantle the entire assembly for any reason.

The Social Influence of Bearings in PTOs:

It is paramount to the successful operation of any OEM to carefully consider the bearings they choose. When generating motion is essentially the standard of success, what does it say when bearings are overlooked? In many ways the decisions made on bearings influence the overall performance and lifetime of all applications that utilize combined bearings and ultimately affect customer relationships, revenue, and perception of brand.

All bearings, including combined bearings, require visual inspections and regular maintenance to increase longevity and maintain productivity. If it’s been a while since you have evaluated the efficacy of your bearings or bearing seals, feel free to take advantage of our no-commitment-required customer application review . We’ll help you see where your opportunities for improvements are. After all, productivity drives revenue.
