Construction

Construction
  • ・The main unit is composed of an austenitic stainless steel sprocket and special double strand stainless steel roller chain.

    ・Comes with special stainless steel connecting links and clips.

Housing (Selling seperately )

Please mount a casing in the following cases,

  • (1) Used at high rotating speeds.
  • (2) Used under abrasive conditions, such as dusty areas.
  • (3) Used in corrosive environments, such as moist areas.
  • ・Special case for Stainless Steel Series roller chain couplings.
  • ・When mounting the casing, the chain coupling life is extended due to the prevention of lubricant splash and dust infiltration.
  • ・For ease of mounting and inspection, the casing can be split at a right angle to the shaft.

Casing Structure

Casing Structure
  • ・The case is a two piece split type aluminum die-cast case with a gasket (cork with synthetic rubber) along the mating surface.
  • ・It comes with four hexagonal bolts and a special (NBR) oil seal.
  • ・The oil seal and gasket are also available for individual purchase. You will need to purchase the lubricating grease separately.
  • ・Install the oil seal on the side subject to greater vibration.
  • ・When used vertically, the oil seal side should be the top side.
    If grease leakage countermeasures are to be taken, please contact us for a quotation.
  • ・Paint specifications :Baked melamine resin coating
  • ・Paint Color :Munsell 8.1YR7.6/15.2 orange yellow
