NSK self-aligning ball bearings combine balls with geometry allowing angular accommodation between rings within the design. This distinguishes them from deep groove ball bearings, without making them interchangeable with spherical roller bearings. That line uses different rolling elements and construction. Angular accommodation does not justify ignoring shaft or housing condition; both belong to the position being identified.

108, 1204 K and 1205 K illustrate a short numeric base and four-digit bases followed by a space and K. The catalog records an 8 mm bore for the first and 20 mm for the second. These attributes do not establish one formula for every base. Retain K and verify seat form in the product record. No suffix meaning or inclusion of a sleeve or accessories is assumed here.
In a fan or transmission shaft, the bearing may sit in a housing transmitting shaft loads. Establish which position provides axial location and which parts lie between shaft and bearing bore. The assembly drawing distinguishes direct mounting from intermediate components. Seat condition remains relevant: the bearing's angular accommodation does not replace assessment of structural deformation, wear or geometric errors.
Send MR Accesorios Industriales the full designation, quantity, shaft size and housing reference. List any sleeve separately and photograph assembly order. If markings are unreadable, add outside diameter and width with measurement details. The drawing supports review. Do not select between self-aligning ball and spherical roller bearings by similar names, or reconstruct a damaged marking using a part from another machine position.
No; its balls and construction define another line.
No, it belongs to the designation requiring verification.
The bearing code does not identify a complete housed unit.

The NSK self-aligning ball bearing is a self-aligning bearing with two rows of balls and a spherical outer raceway that compensates for misalignment between shaft and housing. It is used in applications where shaft deflection or mounting errors make precise alignment difficult. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, in bearings and power transmission.
The NSK K series self-aligning ball bearing is a double-row self-aligning ball bearing with a tapered bore, which compensates for angular misalignment between shaft and housing. It is used in applications where the shaft may flex or where assembly is not perfectly parallel, such as fans, pumps, conveyors and agricultural machinery. MR Accesorios Industriales sells this series in Buenos Aires, Argentina, and helps you choose the correct part number for your equipment.
Just the manufacturer part number is enough: we will quote it and provide dimensions and equivalents via WhatsApp or email.
