1 Pcs, K 7x10x10 Needle Roller Bearing Cage Assembly

Key features

• A radial needle roller and cage assembly without separate inner and outer rings. The prepared shaft surface and housing bore function as the rolling element raceways.
• Slender needle rollers provide radial load support within a small cross-section, making the assembly suitable for mechanisms with limited radial installation space.
• The cage separates and guides the needle rollers, helping reduce direct roller-to-roller contact and supporting stable rotation at suitable operating speeds.
• Verify shaft diameter, housing bore, assembly width, raceway hardness, surface finish, alignment, lubrication, and axial retention before installation.
• Intended mainly for radial loads in gearboxes, transmissions, machine tools, conveyors, agricultural equipment, and compact industrial drive mechanisms. Use separate axial support when axial force is present.

The K Series Needle Roller and Cage Assembly is designed for compact radial bearing arrangements where the shaft and housing bore can function as raceways. Its slender needle rollers are retained and guided by a cage, allowing radial load support within a small installation cross-section. Because the assembly does not contain a separate inner ring or outer ring, the condition of the mating surfaces directly affects operation. The shaft and housing bore should have suitable hardness, surface finish, dimensional accuracy, roundness, and alignment for use as rolling element raceways. Proper lubrication and axial retention should also be provided according to the operating environment.
