Thrust Bearings

Thrust bearings are designed to support loads parallel to the axis of rotation. Single direction thrust bearings are composed of 2 races and a complement of balls. There are two common thrust bearings.
Retainer-based thrust bearings – the retainer separates the balls reducing the load capacity but allowing for higher speeds.
Full-complement thrust bearings – which contain a full complement of balls inside the bearings that touch one another. This design is intended for maximum load capacity and limited speed.
National Bearings specializes in retainer-based custom thrust bearings because they offer tremendous flexibility in design, can withstand high speeds, and provide for greater customization to meet the needs of an application.
Bearing DesignBy working with National Bearings, you can be assured our design team will create custom thrust bearings that precisely fit your need. We will individually address space, load, speed and environmental issues to create bearings that will match the lifecycle of your application without wasting resources on "one size fits all" thrust bearings.
