Simplicity 60 Plus Shafting

In this video we'll explain why matching the shafting or inner raceway to the bearing is absolutely critical to maximizing system performance. PBC Linear's development team, working in close conjunction with engineers from Lee Linear, have together formulated the Simplicity 60 Plus shafting: an inner-race shaft designed specifically for optimal plain bearing performance. Advanced process capabilities maintain the ideal surface finish, resulting in the longest life and highest-performing shaft-to-bearing combination available. There is a myth surrounding shafting that smoother is better. Some suppliers tell you that a finish of 8RA or better is needed. This is simply not the truth. Don't be misled. Don't settle for below-average performance. Don't believe the line that smoothest shafting is always the best. The truth is that a smoother shaft surface actually means decreased performance and shortened life. Upon first installing Simplicity's self-lubricating bearings, the Frelon bearing material experiences a break-in process. This is where small amounts of the PTFE-based liner are actually transferred to the surface of the shaft. Deposits fill the minute gaps or valleys in the surface of the shaft, creating a truly self-lubricating condition. No added grease or oils are required. What happens when the shaft is finished to less than 8RA is that the PTFE deposits have nowhere to settle, and they fall away from the shaft. The bearing liner then continues to think it needs to transfer material to the shaft's surface. The result is that the bearing continually transfers material, ending in premature liner wear and shortened bearing life. Only certified Simplicity 60 Plus shafting is designed and matched to provide maximum performance with Simplicity's self-lubricating bearings.
