What is a filament wound composite bearings?
A filament wound composite bearing is a type of bearing made from continuous fiberglass, PTFE, and polyester filaments within an epoxy resin matrix.
Which industries use BowMax™ Bearings?
BowMax™ Bearings are used across various industries, including agriculture, mining, construction, food machinery, and more.
Do BowMax™ Bearings require lubrication?
No, BowMax™ Bearings are self-lubricating due to the PTFE film that forms on the shaft. Additional lubrication may extend their life.
How do BowMax™ Bearings compare to traditional bearings?
BowMax™ Bearings offer superior strength, load capacity, and resistance to corrosion, with the added benefit of low friction and self-lubrication.
