Products Features


●With typical friction driven accumulation, the accumulation force is associated to load capacity.


●The bearing end cap consists of a precision ball bearing, apolymer housing and end cap seal. Combined they provide anattractive, smooth and quite running roller.


●The design of the end cap protects the bearings by providing excellent resistance to dust and splashed water.


●Utilizes durable, steel sprockets.


●Suitable for conveying weight 10-30kg.


●Temperature range:-5℃~+40℃.


●Please pay attention to the driving force, try best to reduce the frictional resistance between goods and guard bar.

Please make a test running on sample machine if user doesn't have a long-term experience.
