Description
SKF BTW 90 CTN9/HCSP is a reference of thrust ball bearing, within Bearings. Request a quote for BTW 90 CTN9/HCSP via WhatsApp or email with the quantity you need; we respond promptly with the quote and equivalents.
The SKF thrust ball bearing is a component designed to support predominantly axial loads in one direction. Its ball and ring design allows smooth operation and high axial load capacity. It is used in applications where precision and reliability are required, such as machine tool spindles and measuring equipment. MR Accesorios Industriales supplies this brand to provide technical solutions in Argentina.
The designation BTW … CTN…/HCSP is interpreted as follows: BTW indicates the series of high-precision thrust ball bearings; the number following BTW represents the bore diameter; CTN indicates the polyamide cage design with ceramic balls; the digit after CTN specifies execution variants; and HCSP denotes high capacity, bearing steel and special precision. For example, BTW 90 CTN9/HCSP corresponds to a bearing with a 90 mm bore and special features for demanding applications.
These bearings are used in machine tool spindles, rotary tables, precision measuring equipment and positioning systems. In Argentine industry, they are common in the metalworking, automotive and capital goods sectors, where axial rigidity and rotational accuracy are required. They are also used in robotics applications and optical equipment that demand smooth and repeatable movements.
To select a thrust ball bearing, take into account the axial load it must support, the operating speed and the environmental conditions. It is essential to verify axial clearance and adequate lubrication; in high-precision applications, lubrication with high-quality grease or oil is recommended. Mounting must ensure correct alignment between the rings and the support surfaces, avoiding misalignments that reduce service life. Sealing or additional protections depend on the working environment.
Regarding equivalents and interchangeability, thrust ball bearings from different manufacturers may differ in dimensions and tolerances. It is crucial to consult interchangeability tables and verify technical specifications before replacing a bearing. MR Accesorios Industriales can advise you on compatibility with other brands, but it must always be validated with actual measurements and application requirements.
