Return idlers

Idlers

The flat return is the most common idler on the return side of a conveyor and support the belt to prevent sagging and stretching. RS’s Return Idlers are available with a steel roll and 2 drop brackets. In abrasive and sticky environment, our return rubber disc idlers are an option to reduce material build up

PIPE

High precision longitudinal seam-welded steel pipe
Remove internal and external welding bars and uniform wall thickness ensure the roller good dynamic balance
Good out of roundness of pipe ensure the roller have small T.I.R
The pipe is cut and machined using automatic CNC machines, that guarantee the tolerances precision
Roller surface treatment is electrostatic powder coating, thickness of coating approx. 50-60 μ.

SHAFT

Cold-drawn round steel bar
High precision diameter tolerance and perfect match with bearings
Cut and machined by automatic numerically controlled machines
Precise positioning of circlip groove ensure roller have very small axial movement

BEARING

Deep-groove ball bearings
Bearings are filled with lithium base grease throughout its service life
Nylon cage advantage: self-lubricating, abrasion resistance and low heat by friction, low noise, long service life
A variety of brands are available (SKF, FAG, NTN, etc.)

BEARING HOUSE

Made of high quality cold-rolled steel plate, materials SPCC
High precision, smooth and no burr, bearing fit tolerance standard Perfect concentricity ensure the roller low T.I.R

SEAL SYSTEM

Labyrinth Seal uses a new type of roller seal that protects the roller bearings from water and dust at both ends of the roller with the belt conveyor. It consists of five parts: inner seal, outer seal, bearing, middle seal and end seal

LUBRICATING GREASE

Long lasting lubricating grease, working condition -20°c to 120°c

SURFACE TREATMENT

Electrostatic Powder Coating

FEATURES

1. Low Total Indicator Run-out (T.I.R), low rotational resistance;
2. Highly-effective labyrinth seals protected from dust & water into the bearing;
3. Designed and manufactured for a long lifetime
4. Maintenance-free, high-quality sealed ball bearing.
