Product specification

Retaining rings for shafts and axes with available nut

Rings with mounting lip for easy assembly and disassembly

Absorption of axial forces possible

Work like anti-friction washers

Chemical features:

Well suited for solvents, petrol, mineral oils and fats, alcohols and hydraulic fluids; resistant to weak acids and alkalis

Material properties:

POM features an interesting combination of strong hardness with dimensional stability and nevertheless high impact resistance

Shatter-proof

High toughness and hardness even at low temperatures

Very high resilience

Good resistance to stress cracking

Very good sliding and wear behavior, low friction values and good abrasion resistance

High fatigue strength with changing stress conditions

High dimensional stability under heat

Low water absorption

Very high dimensional stability, thus preferred material for precision, machine and apparatus construction; suitable for narrow tolerances

Good electrical properties

Approved for food

Weldable; bondable only after pretreatment
