Guide Rollers and Support Rollers on Ring Saws are wearable items and require changing on a regular basis. The Hycon HRS400 Hydraulic Premium Ring Saw features a 3 groove drive mechanism that outlasts the competition. Guide Rollers should be changed every 4-9 blades. Support Rollers should be changed every 9-12 blades. All Rollers are sold in pairs.
Drive Wheels should be changed every blade (All Diteq/Hycon Ring Saw Blades include a new Drive Wheel).
