80BB12NM 3/4 SPK IDLER BALL BEARING
- Martin idlers are smooth-running and available in oil-impregnated, sintered bronze, extra-duty bearing press-fitted in sprocket and a hardened steel journal case for maximum resistance to wear.
- Steel sprockets used in Martin idlers are accurately machined (not stamped) the same as sprockets normally supplied for power transmission use.
- Martin can also alter existing sprockets and install bearings to make custom idlers.
- Can be used to change the direction of chain motion or to adjust chain tension
