RAND
Machine's Standard Sheaves
are machined from extremely wear-resistant UHMW
(ultra-high molecular weight) polyethylene. This
is a lightweight and cost-efficient manufacturing
material which offers reduced friction and longer
life in comparison to other materials.
| Properties
of UHMW include: |
| •
|
good
chemical and moisture resistance |
| •
|
continuous
working temperature range of -22° to 180°F |
| •
|
self-lubricating |
| •
|
superior
dielectric characteristics |
| •
|
high
stress and crack resistance |
| •
|
shatter
resistance |
| •
|
noise-damping
characteristics |
| •
|
heat and cold resistance |
UHMW
provides very good impact, abrasion and chemical
resistance. It has excellent electrical properties
and exhibits very good impact resistance. UHMW
is RAND's most popular material, mainly due to
its inherent lubricity and low coefficient of
friction.

Temperature range: -22° to
180° F
Following
are some of RAND's most popular custom
materials. We also offer aluminum, hard-coated
anodized or ceramic-coat aluminum, steel, stainless
steel, D-2 tool steel (hardened) 4140-Ht annealed
material and plasma nitride steel.

High-Density
Polyethylene (HDPE)
HDPE is very similar to UHMW and works well
in coated, clean or insulated wire applications.
It is generally a less expensive option.

Ceram-P
(Filled UHMW)
Ceram-P incorporates ceramic particles with
standard UHMW. Together, they form a superior
material that is one of the most abrasion-resistant
options available in today's market.
Color:
lime green
Temperature range: -20°
to 180° F |

Nylon
(Polyamide)
Polyamide is a self-lubricating, general-purpose
nylon that offers outstanding wear and abrasion
resistance, excellent chemical resistance
and low friction.
Color:
off-white
Temperature range: -40°
to 190° F |

Nylatron
— GS
Nylatron is molybdenum disulphide-filled
6/6 nylon. Benefits include excellent wear
resistance, low surface friction and high
strength and rigidity.
Color:
black
Temperature range: -40°
to 210° F |

Delrin
(Black & White)
Delrin provides excellent wear resistance
and also resists fuels and solvents.
Color:
white or black
Temperature range: -20°
to 180° F |
