conveyor roller/idler

1.Seal，D&D rollers forming a complex winding and narrow maze the labyrinth seal is press-fit into the housing and constructed of a resin seal which rotates in conjunction with the roller as well as a separate seal which is secured oddinto the shaft .In addition, it feature the 2# grease pocket which allows the stowing of grease resulting in excellent waterproofing and dust proofing capacity the precise design and manufacturing of the labyrinth seal symbolizes our durable high water proofing/dust proofing capacity.The performance has been sufficiently tested.And also have the flexibility of rotation simultaneously. 2.Bearing，We have developed a technique for press-fitting deep groove radial ball bearing (C3) between housing and shaft at a fixed tolerance.We have a long-term relationship with HRB our rollers select the HRB ZZ/C3 bearing. 3.Housing，We have purposefully used the finest deep stamp material and precision metal mold to produce the housing.The structure reasonably shorten the depth of the housing. Through dedicate welding equipment welding automatic at the same time in order to ensure the overall strength and stiffness. 4.Snap ring，We select the ring from professional factory which use the finest spring steel to produce and have sufficient toughness and rigidity. 5.Shell，The shells are made by dedicated high-precision tubing control according to GB intermediate standards ensure the shell consistency by use special equipment processing. 6.Shaft，The shafts are refined by special processing machinery ensure product qualification rate 100% 1.Seal，D&D rollers forming a complex winding and narrow maze the labyrinth seal is press-fit into the housing and constructed of a resin seal which rotates in conjunction with the roller as well as a separate seal which is secured oddinto the shaft .In addition, it feature the 2# grease pocket which allows the stowing of grease resulting in excellent waterproofing and dust proofing capacity the precise design and manufacturing of the labyrinth seal symbolizes our durable high water proofing/dust proofing capacity.The performance has been sufficiently tested.And also have the flexibility of rotation simultaneously.2.Bearing，We have developed a technique for press-fitting deep groove radial ball bearing (C3) between housing and shaft at a fixed tolerance.We have a long-term relationship with HRB our rollers select the HRB ZZ/C3 bearing.3.Housing，We have purposefully used the finest deep stamp material and precision metal mold to produce the housing.The structure reasonably shorten the depth of the housing.
