SKF 2203 ETN9 Self Aligning Ball Bearings

Description

The bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads. This cage type can be used at operating temperatures up to 120 degrees C (250 degrees F). The company, founded in 1907, is headquartered in Gothenburg, Sweden, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance. Because this bearing type has the lowest operational friction of all rolling bearings, it runs cool at high speeds. Additionally, the bearing is manufactured to normal tolerances in accordance with International Organization for Standardization (ISO) 492:2002 specifications. 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. 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. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. Its open design facilitates lubricating the bearing in place and dissipating heat. 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. All rolling bearings are open, shielded, or sealed.

Key Features

• 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 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.
• 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.
• The bearing is made of low-alloy, through-hardened chromium steel for durability and resistance to deformity under heavy loads.
• 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.
