Drawn cup needle roller bearings

Drawn cup needle roller bearings, as the name suggests, are needle roller bearings with a deep drawn, thin-walled outer ring with either open ends or a closed end. They are characterized by a very low sectional height and high load carrying capacity.

DESCRIPTION

Drawn cup needle bearings are ideal for housing bores that are of low rigidity like cast iron, aluminum or plastic. Mechanical efficiency is improved with needle roller bearings because the rotating radius and torque is small. Due to the small bearing volume and weight, the moment of inertia of the bearing is minimized when put in motion, therefore requiring lower torque.
The outer ring is made by sintered metal. There are two kinds of cages: metal and plastic. The needle roller is made of bearing steel and its movement is guided by the cage.

Dimension inspection: Because the thin-walled outer ring may not be round in the process of production, the dimensional precision of drawn cup needle roller bearings cannot be inspected before installation. Only when the bearing is pressed into the seat hole of the recommended tolerance limit, the bearing can achieve the required precision.
(1)Press the bearing into ring gauge (wall thickness≥20mm)
(2)Use go gauge and stop gauge to inspect the internal diameter of the bearing
