Machine Tool Spindle NU1005 E M TV TN Cylindrical Roller Bearing

Cylindrical roller bearings are available in many designs, series and sizes. The major design differences between the bearings presented in this section are in:

• the number of roller rows (one, two or four)
• the type of cage (with, without or special designs)
• Bearings with cage can accommodate heavy radial loads, rapid accelerations and high speeds.
• Full complement bearings (without cage) incorporate a maximum number of rollers and are therefore suitable for very heavy radial loads at moderate speeds.
• high-capacity cylindrical roller bearings combine the high load carrying capacity of a full complement bearing with the high speed capability of a bearing with cage.
• the configuration of the inner and outer ring flanges (position and number of guide flanges)
