URETHANE ROLLERS

Urethane elastomers are unique because they combine many of the advantages of rigid plastics, metals, and ceramics with the elasticity of rubber. Urethane resists abrasion and reduces the affects of shock and impact on load bearing capacity. Urethane covered rollers will not slip like PVC and will not mar conveyed materials which metal rollers are apt to do. Urethane provides the ultimate in wear resistance and noise dampening, making it the material of choice for our sleeved and tapered rollers. In addition, our urethane shaft adapters, when placed over the roller shaft ends, eliminate frame wear caused by metal-to-metal contact and extend the life of your conveyor frame. The advantages of urethane versus metal, plastic, and rubber materials are summarized below.

Advantages vs Metal

·        

Abrasion resistance

·        

Noise Abatement

·        

Corrosion resistance

·        

Toughness upon impact

Advantages vs Plastic

·        

Non-brittle upon impact

·        

Elastomeric memory - when stretched will return to original dimensions

·        

Abrasion resistance

Advantages vs Rubber

·        

Abrasion resistance

·        

Cut and tear resistance

·        

Higher load bearing capacity

·        

Ozone resistance

·        

Colors available for color coding parts

·        

Harder durometer range

·        

Resistance to mold, fungi, etc

·        

Non-marking

CANTILEVER ROLLERS

Ralphs-Pugh cantilever rollers are available in many combinations of bearings, shafts and tube materials. We offer cantilever rollers for both gravity and powered applications. Cantilevered rollers are unique in that one end of the roller is capped preventing any type of contamination from reaching the bearing. The opposite end has an extended fixed shaft that can be threaded or standard finish. Typical applications are vertical guide rollers and belt guides.

Tubes:

  • Standard white PVC
  • “Hi-Impact” white PVC with UV stabilizer
