Product Description

NTN CZPT CZPT K  1206k 2206K 2207K 2208K 2217M 2218M Self Aligning Ball Bearings
Self aligning ball bearing is a kind of bearing with spherical ball between the inner ring of 2 raceways and the outer ring with spherical raceway.
The curvature center of the outer ring raceway surface is consistent with the bearing center, so it has the same self-aligning function as the automatic self-aligning ball bearing. When the shaft and shell are flexed, it can be adjusted automatically without increasing the bearing load. Self aligning roller bearing can bear radial load and axial load in 2 directions. Radial load capacity, suitable for heavy load, shock load. The inner diameter of the inner ring is a taper hole bearing, which can be directly installed. Or it can be installed on the cylindrical shaft by using the fastening sleeve and the dismounting cylinder. The cages are made of steel stamping cages, polyamide forming cages and copper alloy car cages.
The self-aligning ball bearing has cylindrical hole and conical hole. The cage is made of steel plate and synthetic resin. Its feature is that the outer ring raceway is spherical, with automatic self-aligning, which can compensate the error of self-aligning ball bearing caused by different centrality and shaft deflection, but the relative inclination of the inner and outer rings shall not exceed 3 degrees.
It can bear large radial load and certain axial load. The outer ring raceway of this kind of bearing is spherical, so it has self-aligning performance. When the shaft is bent or tilted, the relative inclination between the inner ring center line and the outer ring center line is not more than 1 ° to 2.5 °, the bearing can still work.
There are 2 kinds of bore in self-aligning ball bearings: cylindrical bore and conical bore. The taper of conical inner hole is 1:12 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and 3 oil holes are machined on the outer ring of the bearing.

What are the common types of self-aligning bearings, such as spherical or barrel roller bearings?

There are several common types of self-aligning bearings, each offering unique features and advantages. Here’s a detailed explanation of some of the common types:

  • Spherical Roller Bearings:

Spherical roller bearings are one of the most common types of self-aligning bearings. They have a spherical outer ring raceway and two rows of barrel-shaped rollers positioned between the inner and outer rings. This design allows for the accommodation of misalignment and provides high radial load-carrying capacity. Spherical roller bearings are commonly used in heavy-duty applications, such as mining equipment, paper mills, and crushers.

  • Barrel Roller Bearings:

Barrel roller bearings, also known as toroidal roller bearings, have a barrel-shaped roller arrangement with a concave outer ring raceway and a convex inner ring raceway. This design enables the bearing to accommodate misalignment and axial displacement. Barrel roller bearings are suitable for applications with high radial loads and moderate axial loads, such as in conveyor systems, printing presses, and industrial gearboxes.

  • Self-Aligning Ball Bearings:

Self-aligning ball bearings consist of an inner ring with two rows of balls and an outer ring with a spherical raceway. The design allows for misalignment compensation and is particularly suited for applications with low to moderate radial loads and moderate axial loads. Self-aligning ball bearings are commonly used in electric motors, pumps, and automotive applications.

  • Self-Aligning Thrust Roller Bearings:

Self-aligning thrust roller bearings are designed to accommodate misalignment in applications with axial loads. They have a spherical rolling element between the shaft washer and the housing washer, allowing for misalignment compensation. These bearings are commonly used in applications such as screw conveyors, heavy machinery, and marine propulsion systems.

  • Adapter Sleeve Bearings:

Adapter sleeve bearings are a type of self-aligning bearing that incorporates an adapter sleeve, which facilitates easy mounting and dismounting of the bearing. They are commonly used in applications where frequent bearing replacement or adjustment is required. Adapter sleeve bearings are often employed in conveyor systems, agricultural machinery, and textile equipment.

These are just a few examples of common types of self-aligning bearings. Other variations and specialized designs exist to suit specific application requirements. It’s important to consider factors such as load capacity, operating conditions, and dimensional constraints when selecting the appropriate self-aligning bearing for a particular application.
