About Isostatic Industries
About Isostatic Industries
Isostatic Industries has manufactured standard and made-to-order bronze bushings and steel-backed PTFE-lined self-lubricating bearing products since the early 1970s and 1980s, growing into one of the leading suppliers of these bearing types in North America. The company is headquartered in Chicago, Illinois, and takes its name from the isostatic press used to compact the powdered metal that forms the core of its bronze bearing line.
The product range spans SAE 841 oil-impregnated powdered metal bronze (sold as Oilube), SAE 660 cast bronze, SAE 863 Super Oilube bronze, and TU series PTFE-lined split steel bushings, which combine the mechanical strength of steel with the heat dispersion of bronze and the low friction of PTFE. Isostatic maintains the largest bronze bearing inventory in the United States and one of the largest in the world, supporting fast turnaround on both stock and custom bearing sizes.
For maintenance teams and OEMs that need self-lubricating bearings without the complexity of grease fittings, Isostatic's broad stock and custom capabilities make it a practical source for replacement bushings across a wide range of machinery. ChatMRO indexes the Isostatic catalog so buyers can search by bore size, bearing type, or SAE grade to find matching part numbers.

Frequently asked questions
What is the difference between Isostatic's SAE 841 and SAE 660 bronze bearings?
SAE 841 is an oil-impregnated powdered metal bronze, sold under the Oilube name, that self-lubricates from pores within the bearing material. SAE 660 is a cast bronze bearing that offers higher load capacity, making it better suited to heavier-duty applications.
What are Isostatic's TU series PTFE-lined bearings used for?
TU series bearings are steel-backed and PTFE-lined, combining the mechanical strength of steel, the heat dispersion of bronze, and the low friction of PTFE in a single thin-walled bushing. They are commonly used where space is limited but low-friction, maintenance-free operation is still required.
How did Isostatic Industries get its name?
The company's name comes from the isostatic press used to manufacture its powdered metal bearings, a process that compacts metal powder uniformly from all directions. This naming reflects the core manufacturing process behind its bronze bearing line.
Does Isostatic Industries offer custom bearing sizes, or only standard catalog parts?
Isostatic manufactures both standard catalog bearings and made-to-order bushings in custom sizes. Its large Chicago-based inventory is intended to support fast delivery on common sizes while still accommodating non-standard specifications.
Where is Isostatic Industries located and how large is its inventory?
Isostatic Industries is headquartered in Chicago, Illinois, where it maintains the largest bronze bearing inventory in the United States and one of the largest in the world. This scale allows for quick fulfillment across a wide range of bore sizes and bearing types.
