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.
