INA K115X123X27-A/-1-3 INAK115X123X27

Needle roller and cage assemblies are single or double-row units comprising cages and needle rollers. As their radial design height only corresponds with the diameter of the needle rollers, needle roller and cage assemblies can be used to realize bearings with a minimal radial design envelope. They have high load carrying capacity, are suitable for high speeds and are particularly easy to fit. If the raceways are produced to high geometrical accuracy, bearing arrangements with high runout accuracy can be achieved. The radial internal clearance can be influenced by the needle roller sort as well as by the shaft and housing tolerances. Needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.

INA Needle Roller and Cage Assembly, Single Row, Series: K Series, 115 mm Bore, 123 mm OD, 27 mm Width, 63000 N Dynamic/170000 N Static Load, Sheet Steel, 4100 rpm Maximum, -30 to 140 deg C

• Radial needle roller and cage assemblies are suitable for applications with a very small radial design envelope, where the raceways on the shaft and in the housing are designed as rolling bearing raceways (direct bearing arrangement)
• Support high radial loads
• Allow high speeds
• Combine the load carrying capacity advantages of full complement needle roller bearing arrangements with the speed advantages of a cage bearing
• High running accuracy
• Result in rigid bearing arrangements
• Easy to mount
• Permit technically straightforward, economical and cost-effective designs
• 1 to 3 micron red needle roller sort
