Rutgerson ROC Block – ball-bearing high-load block with needle-bearing axle

When it comes to peak loads on board, the Rutgerson ROC Block shows its strengths: The unique combination of lateral ball bearings and axial needle bearings distributes the pressure over a larger area – thus allowing significantly higher working loads than pure ball bearing blocks. A professional block for demanding sheet and halyard applications.

Tip: The needle bearing on the axle is more sensitive to dirt than a ball bearing – occasionally rinse the block with fresh water after sailing and lubricate the bearings with a suitable lubricant to maintain smooth operation permanently.
