Product Description
STEEL IDLER ROLLERS
|
steel idler rollers are suited to belt conveyor and pipe conveyors. Rollers incorporate a sealed for life bearing and seal assembly that is designed for optimal sealing and lowest possible drag. |
Design of the roller, shaft diameter and bearing specification is determined by the load experienced on the roller. The shaft deflection at the bearing must be limited to specifications from bearing manufacturers to ensure that the appropriate L10 bearing life is achieved. |
|
Rollers are manufactured to SANS 1313 standards which determine size and performance standards. Alternative standards such as CEMA or DIN (or other required standards) can also be referenced where required. |
Rollers can be manufactured in any choice of face lengths with variety of end shaft designs,as per client requirements. |
Roll construction
-Shell:
ERW tubing in accordance with SANS 657 Part 3 (Conveyor Tube).
-Bearing Housing:
Rollers are manufactured with “turnback” bearing housings which aids roll assembly and improves TIR.
-Sealing system:
Standardized contactless and hermetic multi-part sealing system options Bearings:
Deep groove ball bearings as standard. Open, ZZ or 2RS bearings can be used in variety of bearing brands. LFD as standard, other quality brands on request.
-Shaft: Deep drawn according to BS 970-1 (EN3A) or stainless steel on request.
