NIBL’s shell-type needle bushes are lightweight bearings that offer large load ratings relative to their size. These bearings consist of a shell-type outer ring accurately drawn from special steel strips and further heat-treated for enhanced performance.
NIBL’s needle bushes are available in two types: cage-guided and full complement. The appropriate type can be selected based on the operating conditions.
The cage-guided type features needle rollers accurately guided by the cage and thrust rings. They are suitable for applications with vertical shaft arrangements and light to medium loads, as they are not designed to withstand significant misalignment. They are ideal for high-speed rotation applications.
The full complement needle bushes come in two variants: one with needles retained in the outer rings, offering advantages of low cost, high load capacity, and ease of handling and fitting; and another with grease-retained needles in the outer ring. The latter combines economy with high load capacity by using flat-ended needles that have a greater effective length. These are suitable for heavy-load applications at low speeds.
Since these bearings are press-fitted into the housing, no additional fixtures for axial positioning are required. They are ideal for use in mass-produced articles that demand cost-efficiency and have a wide range of applications.
