Selden 40mm Ball Bearing Triple Block and
Ball bearing blocks are used where the loads
are more moderate and dynamic. The ball bearings provide for good sheave
rotation with the lowest possible friction. Available in 20, 30 and 40
mm sheave diameters.
Stainless steel ball bearing races,
stainless steel ball bearings and glass fibre reinforced sheave for best
bearing strength even under high dynamic loads.
Acetal bearing cage to prevent ball-to-ball
friction and to reduce weight.
Glass fibre reinforced composite.
Safe Working Load: 250kg
Breaking Load: 500kg
Max Line Size: 10mm
Shackle Pin Diameter: 4mm
Ball bearing blocks are typically used for
