It is worth taking care of a durable rotor because its low quality can lead to improper operation of the grinder. This increases the risk of damage to the tool, which translates directly into user safety and inaccuracy of grinding. Therefore, it is not worth choosing the cheapest price when choosing such an important element as a grinder rotor. Our rotor features: Adequate balance winding additionally flooded with resin which makes the rotor more durable and resistant to mechanical damage, moisture and weather conditions. More resistant to corrosion. By pouring resin, the rotor works much quieter. Advantages of our carbon brushes: estimated working time: 150-200 HOURS brushes have two fuses- one on each brush! FUSE - AUTOSTOP- brushes "self-shutting off" protecting the rotor from damage. The fuse operates on the principle of a spring placed inside the brushes, which pops out when the brushes have aged to a minimum limit. The ball bearings carry axial and radial loads in both directions and can be used even at high rotational speeds. LSP brand bearings feature: High quality of workmanship - bearings checked in the factory for manufacturing defects The bearings are manufactured in accordance with applicable standards: dimensions and markings We are the exclusive seller of bearings presented in the offer. Characteristics of bearings with C3 clearance: Luz C3 in a ball bearing refers to the gap that exists between the inner rings and the outer rings of the bearing. Bearings with c3 clearance have a greater distance between the rings than the standard C0 clearance. Why buy C3 bulk bearings Luz C3 in RS ball bearings provides greater precision of operation, which is important for devices requiring precise movement. Bearings with C3 clearance are characterized by greater vibration resistance, which is important in the case of machines with high dynamic load, i.e. electric motors, rotors or hydraulic presses. 2RS ball bearings with C3 clearance are less susceptible to wear. C3 clearance bearings are the ideal compromise between precision and load-bearing capacity relative to bearings with less clearance. Each product is checked directly at the factory for manufacturing defects. Product index : 22-004SLA-2
