Thrust Bearings
Thrust Retainers
Thrust Washers


  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.
  1. Retainer-based thrust bearings – the retainer separates the balls reducing the load capacity but allowing for higher speeds.
  2. 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.

National Bearings manufactures thrust bearings using both balls and needles in a wide range of materials. Designs can include:
  • Thrust washers/races with or without a ball groove
  • Plastic or metal retainers
Thrust bearings can be designed to carry loads from ounces to tons. By changing the size and count of the balls or needles, bearings can be tailored to meet the exact requirements of your application. To accommodate the balance of load and speed in your application, we focus on:
  • Ball /Needle Count
  • Ball/Needle Diameter
  • Material Selection
  • Race Design (flat or grooved)
Environmental conditions must be addressed in every effective design of thrust bearings. Corrosion, friction and temperature can be controlled through careful design. Features that can be tailored include:
  • Balls material selections such as chrome, stainless and ceramic
  • Retainers material selections such as stainless steel, brass, or plastic retainers
  • Washers/races material selections such as chrome, stainless steel and brass
  • Corrosion resistance selections such as plating, passivation, lubrication and rust preventatives
