Products
- Advanced polymers allows a simple, reliable and economical alternative to rolling element bearings. TriStar offers a wide range of products that are ideal for non-lubricated, high-load applications in a variety of climates and operating environments.
Solutions
- Engineers face serious challenges when deciding which bearing materials to select. Plastic and composite materials effectively eliminate many of the issues associated with using metal bearings, while also providing benefits in cost-effectiveness and self-lubrication.
Industries
- With TriStar as your
  in-house engineering department, we can help you streamline maintenance, reduce costs, and improve equipment performance. We take the time to understand your specific requirements and then help you find the right product for your application.
Engineering
- With capabilities including component engineering consulting, material selection, prototyping, manufacturing, and surface modification, our in-house engineers will help you find cost-effective, performance improving solutions for your next project.
About Us
- Established in 1982, TriStar Plastics Corp. provides engineering, custom fabrication and manufacturing of high-performance polymers, composites and self-lubricating bearing materials. With engineering and sales offices coast to coast we stand ready to serve you.
Resources
- As your in-house engineering department, our goal is to provide the broadest range of resources to help you find solutions for your most challenging applications.

Calculators

Here are some useful calculators you can use to help you with your bearing and plastic component design.

Plain Bearing: PV

Bearing Application Type:

Load - "L" (lbf): RPM - "n" (revolutions per minute): Shaft Dia (in): Bearing Width (in): Surface ID (in): Surface OD (in):

Bearing Material:

Calculated Value

Limits for this Material

P (psi):

V (sfpm):

PV (psi-sfpm):

Radial Terms

L = load on bearing, pounds force

n = Shaft speed, rotations per minute

d = Diameter of shaft (ID of bearing), inches

w = Bearing width, inches

P = Pressure on bearing, psi

V = velocity of bearing surface, feet per minute

PV = Pressure × Velocity

How to Use: Select the unit to convert from in the input units list pull-down. Select the unit to convert to in the output units list pull-down. Type the value to convert from into the input box on the left. The conversion result will immediately appear in the output box.
