SKF 2203 ETN9 Self Aligning Ball Bearings

Description

All rolling bearings are open, shielded, or sealed. This cage type can be used at operating temperatures up to 120 degrees C (250 degrees F). Due to its optimized internal design, an SKF bearing with an E suffix has a higher load rating than a standard SKF bearing of comparable size. The bearing has a normal radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. The bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads. Its open design facilitates lubricating the bearing in place and dissipating heat. This bearing has a straight bore for fitting on a conventional cylindrical shaft. This bearing has concave sphered housing rings to compensate for static angular misalignments between the shaft and housing in applications subject to shaft deflections or mounting errors. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. It is suitable for applications supporting moderate radial loads and moderate to low thrust loads. Because this bearing type has the lowest operational friction of all rolling bearings, it runs cool at high speeds.

Key Features

• This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors.
• Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use.
• The bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads.
• This bearing has an injection molded snap-type cage made of polyamide 66 to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise.
• This self-aligning ball bearing is for use in commercial and industrial applications including film processing equipment, office automation, vertical spinning equipment, and industrial countershafts, among others.Rolling bearings use.
• This SKF double-row self-aligning ball bearing is an open bearing, and has an optimized internal design, cylindrical bore, reinforced polyamide cage, and normal clearance rating.
