      • Ball Bearings: High compression strength carbon black Acetal

    Universal Bearing

    The Ronstan Universal Bearing incorporates proven 2-stage bearing system with proven dynamic and high static load performance.

    Stage 1 - Under moderate loads, Acetal ball bearings ensure minimum friction.

    Stage 2 - Under heavy loads, where deformation of ball bearings alone would result in increased friction, a sliding Acetal bearing on a polished stainless steel race takes over, maintaining low friction performance.

    Additionally the ball bearings are configured to act as a thrust bearing between the sheave and cheeks, preventing the sheave from rubbing on the cheeks and causing friction when the line lead in and out of the block isn't perfect. Particularly important for cheek blocks.

    Alloy cheek plates

    Block cheeks are manufactured from the highest quality alloy for maximum strength. Material optimization and the cut-away design minimizes weight and allows easy fresh water rinsing of salt and debris from the bearings. Cheek design has been further styled with flaring at the block throat and reduced gap between the cheek and sheave, minimizing rope wear.

    Universal head

    The head assembly incorporates a brass bearing washer to provide smooth 360° rotation of the post and shackle. A set screw arrangement allows the head to be locked at 0° or 90°.

    Shackles are high quality forged grade 316 stainless steel.
