A Profitable Solution to Paper Mill Rope Sheave Problems--SKF
Rope sheaves have always been a frequent cause of maintenance problems. If the sheaves are not running properly, the rope can slip, resulting in rope wear and paper tail tears. Worn ropes can break, requiring unscheduled shutdowns. Lubricant leakage damages the paper, and the need to access hazardous locations for relubrication can be risky for maintenance personnel. For such situations, SKF offer a unique rebuild service that includes the use of component upgrades to make rope sheaves virtually maintenance-free for two years and more.
Another less common but important issue is the danger of sheaves falling off their shafts, causing damage to the product, the felts, the rolls or even worse, people.
Most mills have learned to accept these conditions as normal, and use preventive maintenance to minimize their possible impact. The sheaves are periodically removed and replaced with new or refurbished sheaves, or are simply equipped with new bearings. And still, failures occur during machine startup
