BACKSTAND IDLERS SERIES SBS (REPLACES RBS) -SPRING TENSION
The SBS series of backstandidlers offer an economical method of tensioning and abrasive belt for manual grinding applications.
Tension is provided by a torsion spring. The 6” dia. pulley is machined from an aluminum casting and rotates on sealed ball bearings. The arm and base of the backstand are made of cast iron.
Model SBS-4 for belts of 4” width or less
Model SBS-6 -for belts of 6” width or less
Table Height Adjustment
Accessories:
Angle Mounting Brackets
Shown on the front of this bulletin. When the backstandidler is to be at floor level, the angle mounting brackets position it at an angle that simplifies mounting a guard.
Pedestal
Provides a mounting for backstand idler at approximately the same height as the contact wheel.
Universal Joint
Provides the advantage of removing the tracking knob from the base of the backstand and repositioning it at the front of the machine within easy reach of the operator.
SERIES ABS-HD -AIR TENSIONED
The ABS-HD series is adequate for grinding applications where pressureassist units are used to apply grinding pressure. Tension is provided by a heavy duty air cylinder. The 9” dia. pulley is machined from an aluminum casting, & rotates on sealed ball bearings. The base of the unit is a weldment.
Model ABS-HD-4 for belts of 4” width or less
Model ABS-HD-6 -for belts of 6” width or less
TORO DROP-IN REPLACEMENT
Toro Drop-In ReplacementThe TR-4 and TR-5 are dimensionally identical to the old To ro Backstand Iders. The Idler pulleys are crowned aluminum. 9” diameter, and 4 1/4” (TR-4) or 6 1/4” (TR-6) wide. Tension is supplied via two torsion springs. Tracking is adjustable by rotating the idler pulley shaft, screwing it in or out. These Backstand Idlers are dimensionally equivalent to the old Toro Backstand Idlers, enabling them to be “dropped in” as replacements.
