The SEALMASTER SF-T series Y-bearing housing with insert is a 4-bolt flange mounted bearing, designed to support rotating shafts in applications requiring rigid mounting and easy installation. Its robust construction and sealing system make it suitable for demanding industrial environments with dust, moisture or moderate loads. MR Accesorios Industriales carries this line as a brand, with more than 80 years of experience in the industry.
The SF-T series designation is interpreted as follows: the letters SF identify the family of flanged housings with insert bearing, while the number following SF- indicates the nominal shaft diameter, as in SF-20RT for a 20 mm shaft and SF-32RT for a 32 mm shaft. The suffix RT indicates specific construction features of the series, such as the sealing type and the insert locking method. This nomenclature allows quick identification of the housing size and configuration.
These housings are used in a wide variety of industrial applications in Argentina, such as belt conveyors, agricultural machinery, food processing equipment, ventilation systems and packaging lines. Their 4-bolt flange facilitates mounting on metal or concrete structures, providing stable support for shafts rotating at moderate speeds. They are common in manufacturing plants, warehouses and agro-industrial facilities where durability and low maintenance are required.
To select the right housing, consider the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert seal is key to retaining lubricant and excluding contaminants; in humid or dusty environments, choose versions with higher protection seals. During installation, verify the alignment of the flange and shaft to avoid additional stresses, and ensure adequate lubrication according to the manufacturer's recommendations. The insert must be locked to the shaft using the set screws or the corresponding locking system, following the specified torque.
Regarding equivalences and interchangeability, SEALMASTER SF-T series housings can be replaced by products from other brands that share the same flange dimensions, shaft diameter and load capacity. It is essential to verify the mounting dimensions and insert type to ensure compatibility. MR Accesorios Industriales can advise you on selecting the right alternative for your application.
