Needle cages are inexpensive and very easy to install, often fitting by hand without the need for tools. They may be manufactured in two parts and mounted on an inner raceway between two shoulders, which enhances the rigidity of the shaft.
The double cage design features two rows of needles, comprising two bearings side by side in one continuous unit. This arrangement facilitates the easy fitting and stability of parts such as idler pinions. The double cage can also be produced in two separate parts.
NIBL manufactures cages from steel, polyamide, and brass materials. The needle rollers used in these assemblies are made of high-carbon chrome steel, which is hardened, ground, and lapped to close tolerances for diameter and roundness.
The needle cages provide both inward and outward retention for the needle rollers. Their design ensures maximum cage strength, consistent with the high load ratings of needle roller bearings. The accurate guidance of needle rollers by the cage bars allows for high-speed operation. Needle roller and cage assemblies are available with either one or two rows of needle rollers.
NIBL’s steel cages offer advantages of great rigidity, mechanical stability, and low weight.
