ZKL Spherical Roller Bearing, Inner Dia 180 mm, Outer Dia 280 mm, Width 74 mm, 23036CKW33J C3 NF

A ZKL Spherical Roller Bearing Inner Dia 180 mm Outer Dia 280 mm Width 74 mm, 23036CKW33J C3 NF is a type of rolling-element bearing that is designed to accommodate high radial loads and moderate axial loads in both directions. It consists of an inner ring with two raceways, an outer ring with a spherical raceway, and barrel-shaped rollers with symmetrical rollers between the inner and outer ring raceways. The center of curvature of the outer ring raceway surface coincides with the bearing axis, enabling the bearing to accommodate misalignment or shaft deflection. The spherical shape of the rollers enables the bearing to accommodate misalignment and angular deviation between the shaft and housing, which can occur due to mounting errors, shaft flexure, or thermal expansion. This capability reduces stress concentrations and extends bearing life. Spherical roller bearings are commonly used in heavy-duty applications such as mining, construction equipment, industrial machinery, and paper mills, where high radial and axial loads, as well as misalignment, are common. They are available in various designs, including: Straight bore: The inner ring has a cylindrical bore. Tapered bore: The inner ring has a tapered bore, which facilitates mounting and dismounting using an adapter sleeve or withdrawal sleeve. This design also allows for the adjustment of internal clearance. Sealed bearings: Some spherical roller bearings are equipped with seals or shields to protect against contaminants and retain lubrication. Cage options: Spherical roller bearings can have different cage designs, such as steel, brass, or polyamide cages, to suit various operating conditions and requirements for speed and temperature. Overall, spherical roller bearings offer robust performance, high load-carrying capacity, and the ability to accommodate misalignment, making them suitable for demanding applications in various industries.
